Check your electric car battery pack state of health with the OBD LINK MX+ (Amazon): amzn.to/3oWbp9u . Has the 2020 Renault Zoe lost already 10% of its original range in only 3 years time and only 23.000 km? How do you measure Battery SoH and did you ever get your pack replaced because of it at the dealer? Was it tough to convince them to do this?
I had the BMS / LBC updated because the predicted range was behaving strangely: after resetting the trip meter it showed very low range and then counted up while standing still...
Thanks for your suggestion and for sharing. I think my wife should do the same with her car, I have the feeling the range is more than it shows. Let's hope they can do it for free with the next planned service interval!
SoH=94,74 after 129,650km driven om my May 2020 ZE50 R135 (it had 8200km on the odometer when I got it in Nov-2021). You NEED to get the "Battery managment System ACTIS 64453" update. And "Energy screen + improved Pre heat system ACTIS 64756 and ACTIS 64273". This is needed for all spring 2020 cars. They will complain and trying to avoid doing it. but stand your ground and demand it. Both helps a lot. The usable "range" is the average related to the SoH and the avarage consumption from the latest 10 trips (so that part is temperature dependent). And without doing the ACTIS 64453 it is basically useless as in that software you have it is very temperature dependent. Doing service on Zoe is an expensive 20 min joke. They only replace the cabin filter. All other is just useless checkpoints that make zero sense. The first that really matter is 12V battery replacement after 3-5 years and braking fluid after 5 years (can not be done at home due to ODBII operation is needed to properly flush the ABS system).
Many Thanks this is by far the best number I have seen on a Renault Zoe after that many kilometers. I'm putting your comment on the top and will copy paste it for my wife to demand the update and send it in writing to Renault Netherlands. Many thanks for sharing this is very nice and super helpful!
My Zoe has recently passed 160,000 km and the SoH is now at 93.38%. The Zoe ZE50 battery pack warranty is less than 8 years and less than 160,000 km AND below 70% SoH for a warranty replacement (75% for ZE40). My driving habit recently may be the reason for the faster degradation. For about the last 100 traveling days, I have returned home with less than 10% SoC... For the first 100,000 km, I only got back home once with less than 25% SoC. Regarding needed services. I have just figured out that the brake fluid exchange is just like any normal car. Also, the coolant exchange, using the original Renault coolant is a must, but it MUST be a vacuum exchange procedure to avoid air traps. Air pockets might destroy the electronics due to lack of cooling, so be aware... I had to replace the brake pads on one rear wheel due to crappy adhesive, so the brake material dislodged from the steel plate. Figuring out the EPB (Electronic Parking Brake) took some time, but basically, it is just 12V DC directly to the motor and reverse it for changing direction. But I will replace both rear discs and a new set of brake pads on both sides as that side with the faulty brake pads was severely corroded. Maybe I will do a YT-video about it (at least the second side).
Looks like you haven't had the BMS update. My June 2020 Zoe had a SOH of 88% prior to having the update. After update the SOH showed up as 98.8% in June 2021. After 25000 miles and 3 1/2 years it is now 96.6% .
Thanks for letting me know. I think I will indeed double check this for my wife at its her car. I hope the BMS update is for free even when out of the warranty period?
You are very welcome, glad I could share this with other people. Such a cool tool to have in your pocket, can make starting a discussion with a dealer so much easier this way. But I hope you will not need it ;)
Do you limit how much you charge? I remember a video by Matt from GoGreen autos where he said he looks for high mileage evs for friends and family, both because they are significantly cheaper, but also because the battery health is usually good on high mileage EVs. He reckons this is because cars that do lower mileages are often charged at home to 100% and left full for days. He says this is the worst thing for battery health, but high mileage cars usually spend much less time at 100%.
Hey that's an important one. Didn't realize that. For first year my wife charged to 100% always but now we don't charge beyond 80-90%. Unfortunately the Renault Zoe does not have a charge limit setting like for example my Opel ampera-e / Chevy Bolt EV
@@maximaalski I'm looking for a used 2020 Zoe at the moment. I just discovered something really interesting. On one dealer they have two Zoes that have done 60,000 miles / 90,000 Km. Looking at the dashboard pictures on their site, I did a quick calculation using the remaining range and remaining charge shown. It's a rough estimate, but those two high mileage cars both came out at 208 miles when 100% full. But they also have two cars that have done 20,000 miles / 30,000 Km, and by the same method they both have 185 miles range at 100%! Sure, I have no idea if the last two cars have recently been driven hard, affecting the range estimate. But even so, 208 real world miles from 4 year old high mileage car is pretty good I think.
I don't know much about electric stuff, but here in Germany you can request a full certified battery check from a dealer, they usually don't have it ready, but you can request it and they do it for free, because they want to sell the car. There is a very low chance that they scam you with these numbers, because they have to give you a certified check from a third party. But now to my main part, this certified check takes several hours, I don't know the details but I think they empty the battery and recharge it during the process and check all kind of things. So Im wondering how this little device would show accurate values after such a short time. I would assume that the certified checks would use the same tools, if they are accurate enough, so I also have to assume that this little device does only a assumption based on some of the current battery values and doesn't show the real health state of the battery. This point would also explain why some people comment about different values after an software update, a real health check wouldn't care about any software, because it is done with the battery directly and will always show the real numbers, no matter which software update.
Hey thanks a lot for your comments. I'm also definitely not an expert. I believe that the OBD device with the software that monitors different aspects of the main battery is a good compromise. It puts some of the power back in the people's hands to measure some of it themselves. Then if they see something abnormal bring it in for the full testing you suggest. I would most certainly trust the Germans with this and the certificate approach 😀 I was shocked that my wife's Renault Zoe dealer does not want to update the BMS for free. They want 75 EUR for it or that we purchase some accessories and they give it then for free. I'm going to write Renault directly about it. What do you think? Shouldn't a BMS update always be included and pushed to the car for free. Since it is responsible for monitoring the main battery and how it charges et cetera? Have a great weekend ahead 👍🍺
@@maximaalski We have inspections which cost money where they check general things, this also includes software updates, so Im not sure if or how much it would cost us to just update the software alone. But I agree that 75 for a software update is way too much, The BMS software seems to be buggy in some cases, so it should be free. Maybe you have to word it differently, instead of asking about the update, complain that the battery (or range) is too low and start to talk about battery warrenty and stuff, maybe they will get worried and update it for free :D
The measured SoH may be incorrect. Try calibrating it. Drive the vehicle until it reaches 1% charge. Then, park in front of a max. 11 kW charging station. Set the temperature to activate the air conditioning compressor, and wait for the vehicle to shut down itself. Let the car remain locked for 1 hour. Then, connect the charger and wait for it to reach 100% charge completion. Afterward, you will see the true SoH value.
Hi that's indeed a very good tip I haven't thought of yet. Basically run it to complete zero and follow your steps. I will give this a try soon with my wife's car and see what happens. Thanks!
Generally manufacturers recommend below 10% then to 100% but I guess the lower the better. And to do this every 3 to 6 months I know Tesla do, and MG Tesla bjorn ( bjorn nyland) has just posted 3 videos about this and a cupra born, this didn't work in his case but I suspect it could be a faulty battery pack in the cupra.
@danuk2005 Thanks for the comments and reference. I will keep on doing this in the Renault Zoe the results are still there. Not sure why in my Opel Ampera-e I did not notice anything again first time maybe I will try it again 👍😀⚡
Good point; but this method will not take in to account the losses from charger to the battery which is perhaps 5-10% (if I haven't missed your point)... I think degradation measurement is very difficult and only an approximation is possible and I will propose another method: If you charge your car 20 to 80% say five times which makes 300% over the period (assuming you've zeroed the consumption at the beginning) now read your car's total (drive and accessories ie a/c etc. - Megane Etech seperates these two so you need to add) consumption meter then divide by 3 for our example case you would get a better battery capacity measure; I think. What is your thoughts ? Brgds from Istanbul
@gokcemuratozaydn799 Hey thanks for your suggestions. This is good and worth trying too as another means of checking and monitoring this. These data combined with one's own observations about how the range developed can help convince a dealer to check your car under warranty. I also noticed an improvement in range after I fully charged the Zoe battery then drain it to zero and then recharge it to full again. The range stayed and was probably there due to some recalibration of the battery. Thanks for sharing your suggestions here with other viewers!

Thanks for your confirmation on this. That's same car as my wife's but with more kilometers on the clock. It seems like this is just a reference number, but more parameters are required to interpret the battery condition and degradation. How about in the winter when it's cold. You have still the feeling the range is equally as good there as it was when you got it?
Not yet from my side. It's my wife's car but she agrees next time we will force the dealer to update it based on all the useful feedback we have received here. The update is essential and should be provided to anyone free of charge by Renault. Battery management software updates are in my opinion an integral part of the car.
Hello, thank you for this very useful video. I have just bought a 2020 Zoe R135 ZE50, (23000 MILES/37000km) and shocked at the numbers in range at full charge. I've ordered a cheaper OBDII device, hoping to get some insight on battery SoH and software to improve it? Currently - In ECO mode, 168 miles on full charge. It was 148 not on Eco mode. It's not summer but it's still between 15-18 degrees here, so absolutely not winter either. The car got delivered today, is there anything else that I need to be thinking of when talking again with the dealer? Thank you
Hello you're welcome. I would check with your dongle and download the CanZe app for Renault Zoe car from the Playstore or Apple Store. Do a check for battery state of health when charged full. Then discharge complete and recharge to 100% and check again. If you have the feeling the range is too low I would present the battery state of health figures you found together with the low range to the dealer and demand an inspection since the battery is under warranty still. Also an upgrade of the BMS system could be done free of charge if that is necessary. What really helped me is the complete drain to zero percent (drove it to 2 percent parked it and did the rest to get to zero with airco full blasting on a safe spot). And the recharge via the home socket all the way to 100 percent. I got somehow better readings and a bit more range consistently. Let me know how it goes and I hope it was helpful. Drive it around and drive it normal and empty a few times and it should be better with the range. If in doubt go to the dealer and write Renault customer service in your country with a formal complaint. Good luck and enjoy the new car .. I'm sure all will be alright we love the Zoe and is very reliable too 👍 By the way some people here wrote some very good comments and suggestions worth checking them out!
I havnt got a ev but interested in one for a future buy. I regularly check the SOH of my sandero car 12v battery so i wonder if the SOH that you are checking is the 12v battery which operates lights etc in the car and not the main motor battery . I would anticipate the voltage drop that you are showing from the 12v battery and anticipate replacing this as part of normal maintenance around 5 years just like a non ev car The EV 12v battery charge is relenant is that it can show an engine fault I understand when it gets too low when in fact the main hv battery is perfect. Ambvol
Hello thanks for your message. I can highly recommend an EV. We have an 2019 Opel ampera-e for longer distance (65 kWh) and a Renault Zoe (52 kWh). The Zoe statistics shown in the video are from the main battery pack and state of health. The 12v starter battery needs to be checked separately, but I would check it rather with clamps on the battery itself with a conventional reader when the car is turned off and left idle for 15m or so. I think that statistic would be more reliable than via the OBD tool. The car recharges the 12v periodically when plugged in or left idle. But My 12v battery is now almost 5 years old and I will be replacing it as a precaution probably by the summer. I always drive around with a booster battery pack in my trunk just in care especially for loner trips not to get stranded somewhere. Just common good practices as with a normal car. Have you already decided what type of EV you're looking to buy? I hope you will like it and let me know if you have any further questions Take care and happy new year!
What you check on the 12V battery is the CCA and the steady-state voltage. Those two figures give a rather good indicator of the state of the 12V battery. I have so far not read anything about problems with the ZE50 12V battery (if not the result of total neglect). The onboard 400V/12V charger has a 200A charging capacity and has very high efficiency combined with smart charging (also temperature-dependent charging voltage). On the ZE40 it is a rather different story. 400V/12V charger with only 100A capacity and a constant voltage charging scheme so overcharging in summer and undercharging in winter conditions. The ZE40 only charges the 12V battery during driving and active charging. Never when the charger is "only" connected, so having the ZE40 just plugged in for a few weeks and not used may destroy the 12V battery...
Hi Folks. I am about to Check my Soh soon. (R135, 52kWh, 2020, 29tkm) When it comes to updating the firmware of LBC, what was the Price for such Update? I read some Blogs which stated more than 500€ !?!
Hello unfortunately I don't know this but I'm sure there will be people here who commented under my video that know and will comment I hope to help you with this. Let me know and please share if you know. One could also mention that the range has dropped and less battery SoH during warranty period and maybe then they will do it for free? I will try this trick during next service interval 😁
It was free, but took time and effort to convince dealer. The symptoms in my case, May 2020 Zoe were: 1. Low SOH like 88%, 2. Lower range, 3. Huge time to reach from 99 to 100% SOC (like 30-45 minutes..), 4. Huge predicted range change between 99 to 100% SOC. All these reported and documented issues helped convince dealer to apply BMS update. After BMS update SOH went up to 96%, and range went up and charging from 99 to 100% SOC takes just couple of minutes. Good luck
Hi. Do I have to buy the paid version to see the battery life? Because after connecting and selecting Zoe, it shows me an empty field in place of soh. . Thanks
Hello no you don't have to. I use the free one only. Maybe depending on your model and year there are several connection profiles in the app for the Zoe. I suggest playing around with the connection profiles for Renault available and see if one differs from the other. I hope it will work for you!
Hey I have got the same car, only a couple of months younger and 33000km. I have measured the SOH over a couple of years using the CANZE - app., extracting the same data as the CAR SCANNER. Over time SOH has gone from 98% (spring 21) to 86% (winter 22) to 95% (summer 22) to 88% (winter 22) to 97% (spring 23) and now 92% (summer 23). So I dont find it very reliable. I have for 1½ years calculated the SOH : Energy (kWh) when full (green light at the socket) divided by 52 kWh. The results from these calculations also varies with seasons but are generally higher as the measured SOH's - last calculated 97% vs measured 92%.
Hey Jan many thanks for sharing this and your experience with the measurements and actually interpretation of this SoH number. Quite amazing to see all the fluctuations over the years and especially the seasons. I will actually try out your strategy here and see what numbers that produces. Did you have to drive the Zoe completely to almost down to 0% to get the best readings or this is not required? Also curious if you ever had a discussion about your findings with the dealer... Did they say anything about your investigations, or did they do an update of the BMS? Many thanks for the feedback and have a nice evening.
Hey Maximaalski. I have not talked to the dealer about the issue - I dont think it would be to much use. I did not drive down to zero. When calculating the SOH I used data from Canze showing availible energy (kWh) then charging to finish divided by nominal capacity (52kWh). I found a relation between battery temperature (°C) after charging to full and SOH: SOH= 0,4696 x temp. + 87,644 with R^2 = 0,63 Have a nice day🙂
Do you know if your Zoë is on the latest BMS firmware, (I couldn’t get that bit to work on canZE) but maybe worth investigating. My dad has a 22kwh Zoë 6 year old with 98% SoH.
My concern is yhe obd2 you recomend clearly states not suitable for hybrid or electric so if this is the case are you seeing the auxiliary 12v battery condition?
Hi I actually have never used my MX+ from obdlink (yet) to check the 12v battery status condition. Only used it for checking battery State of health and main traction battery stats. This works perfect on both my Opel Ampera-e (Chevy Bolt EV) and my wife's Renault Zoe (both new electric cars from 2020). I do believe you can pull 12v battery stats from it, actually I can do this and take a look for you and send you some Screenshots. I'm quite curious myself as now my 12v battery is 4y old. Perhaps need to replace it as a precaution. Another way to check would be with traditional clamps and voltage readers. Would you like me to do that with the MX+? Specially what 12v stats are you looking for... To determine whether the 12v starter battery still has decent voltage? Best Regards , GJ
Battery state of health BOH are tests used for both the car batteries . The 97% you have quoted would be about normal for the 12v battery. are you sure you are measuring the right battery .
My SoH statistics show up right underneath DC battery capacity 47,78 kWh in another test. Then right underneath is the Zoe DC battery State of health showing 90,19% in another reading I did. Although 12v could be read with the OBD I would still recommend a separate reading device with clamps on the 12v battery poles when car has been left idle for some time. What do you think can you get reliable readings for the 12v with the OBD only? I always drive around with a 12v battery booster just in case I long trips. Will be replacing my 12v now in my opel ampera-e as the car is almost 5y old
Hello Josh, I havent checked yet the BMS version in my wife's 2020 Renault Zoe, but I'm going to do that one of these days with the OBD reader, then check online in the spreadsheet I found if it is the latest BMS. If battery SoH is again like this, I will approach Renault Zoe to update the BMS of this is not the most up to date Version in the car. I guess this would be the best way to approach this, what do you think? Have you had a drop of range and then did a BMS update that improved things?
@@maximaalski Hi,i have also a drop of range,i don’t know the SOH,i will ask the dealer soon for a check up,did you see this one; ruclips.net/video/iA3p7p3AF60/видео.htmlsi=lPpH2Mg5ANLkWpMQ Or i will buy a obd so i can see for myself,thanks and stay sharp
@Josh-du7ij Thanks for the video, I will watch it today. Yeah can highly recommend getting an OBD they are great for checking stuff and can even get you out of trouble resetting a code if you get stuck somewhere. Let me know please if you had a good feedback and experience with the dealer and what your strategy was convincing them to do the check. Good luck!
Hello thanks for your experience. I honestly don't know but in a previous comment someone named Alper made a good suggestion to drive the battery all the way done to nearly zero and then recharge it to 100. Maybe I will also try this before I do more measurements
Thanks.... That sounds more or less what others have been saying and I've read. Has your expected range also gone done you think or haven't really noticed that?
Thanks for sharing. That's a decent amount of kilometers. Based on what I'm reading this seems "normal" something around that number of state of health. You have almost same number as my wife's Zoe. I wish it would just be a 100%. Have you also noticed the almost 10% reduction in range or not really?
no. because i learn how to drive. and i use for summer MICHELIN E·PRIMACY tyer. i usualy use 11 kwh charge. summer consumtion 10.9 . winter 18@@maximaalski
Sorry to hear that. Maybe something updated in the app that I have suggested in the video. I will try again myself soon to see. I can also recommend the CanZE app that a lot of Renault Zoe drivers like and also allows you to view OBD data via the dongle
Impressive Zoe driving! Do you find the range reduction an issue or are you not that bothered by it? I recently charged to 100 and drained to zero and then again to 100 and got quite a bit of range back 👍
@@maximaalski I use it on urban and interurban trips. The autonomy it provides me is more than I need. I can also enter the city center and park for free or with significant reductions.
I know :( I found it very tough for some reason to pronounce it the correct way. Whatever I did it just flew out in the wrong letter order. But I've been practicing and in the future I will try not to mix it up any more.
Haha 😂 Yes Barrie thanks for rubbing that in 😉 But you are very right! Current EVs are really great but this uncertainty about how battery will degrade and hold up over time really needs to be dealt with by the industry. If you read the guarantee most ev companies say something like 80 degradation over x amount of years. If you ask me it should be no more than 10% or rather zero like with regular cars.

Agree, they will try to prevent you or make it as difficult as they can for you to claim the warranty. Luckily there are now more certified companies that can test the battery and generate a report used for escalation and claims. A great way to start is to test it yourself too if you suspect something. I hope you have not had a bad experience yourself with the dealer about this topic?
Haha, yes I noticed this too. Very difficult I finally got it right but now the video is already out there. Glad you liked the video. I love having an OBD available in case I may need one 👍
@@maximaalski You are right. But i think the problem is that most people with an electric car drive 50 miles a day from house to work and back. That's let's say 10% used. Still, people see a free chargepoint at work? Plug it in. Juice up to 100% again. Back home with still about 90-95% charge on the home charger. A trip? Turbocharge in 30 minutes. I say, if it's bad for your phone, it's bad for your car. Same batteries, just a lot bigger.
Ha, dat klopt inderdaad! Ja ik begrijp je punt. Wij zijn gek op onze elektrische auto's, voelen ons alleen misleid doordat die standaard Battery degradatie plaatsvinden. Ook al is het binnen het acceptabele niveau. Met een brandstof tank had ik niet na 3 jaar 10 procent verloren. 10% op een relatief gemiddeld bereik van 350km is 35 km bereik eraf. Ik had verwacht dat dit soort cijfers pas na 100.000 km zouden optreden, niet al zo snel!
I have 1126 full charge cycles, 1150 partial charge cycles, 20521kWh used energy from the battery, 786kWh returned from regenerative braking, and over 160,000km driven with a 93.38% SoH. So your statement is faulty. No "KABOOM" yet... You are a joke.
Check your electric car battery pack state of health with the OBD LINK MX+ (Amazon): amzn.to/3oWbp9u . Has the 2020 Renault Zoe lost already 10% of its original range in only 3 years time and only 23.000 km? How do you measure Battery SoH and did you ever get your pack replaced because of it at the dealer? Was it tough to convince them to do this?
I had the BMS / LBC updated because the predicted range was behaving strangely: after resetting the trip meter it showed very low range and then counted up while standing still...
It was a firmware software issue
Thanks for your suggestion and for sharing. I think my wife should do the same with her car, I have the feeling the range is more than it shows. Let's hope they can do it for free with the next planned service interval!
SoH=94,74 after 129,650km driven om my May 2020 ZE50 R135 (it had 8200km on the odometer when I got it in Nov-2021).
You NEED to get the "Battery managment System ACTIS 64453" update.
And "Energy screen + improved Pre heat system ACTIS 64756 and ACTIS 64273". This is needed for all spring 2020 cars.
They will complain and trying to avoid doing it. but stand your ground and demand it. Both helps a lot.
The usable "range" is the average related to the SoH and the avarage consumption from the latest 10 trips (so that part is temperature dependent). And without doing the ACTIS 64453 it is basically useless as in that software you have it is very temperature dependent.
Doing service on Zoe is an expensive 20 min joke. They only replace the cabin filter. All other is just useless checkpoints that make zero sense. The first that really matter is 12V battery replacement after 3-5 years and braking fluid after 5 years (can not be done at home due to ODBII operation is needed to properly flush the ABS system).
Many Thanks this is by far the best number I have seen on a Renault Zoe after that many kilometers. I'm putting your comment on the top and will copy paste it for my wife to demand the update and send it in writing to Renault Netherlands. Many thanks for sharing this is very nice and super helpful!
My Zoe has recently passed 160,000 km and the SoH is now at 93.38%.
The Zoe ZE50 battery pack warranty is less than 8 years and less than 160,000 km AND below 70% SoH for a warranty replacement (75% for ZE40).
My driving habit recently may be the reason for the faster degradation. For about the last 100 traveling days, I have returned home with less than 10% SoC...
For the first 100,000 km, I only got back home once with less than 25% SoC.
Regarding needed services. I have just figured out that the brake fluid exchange is just like any normal car. Also, the coolant exchange, using the original Renault coolant is a must, but it MUST be a vacuum exchange procedure to avoid air traps. Air pockets might destroy the electronics due to lack of cooling, so be aware...
I had to replace the brake pads on one rear wheel due to crappy adhesive, so the brake material dislodged from the steel plate. Figuring out the EPB (Electronic Parking Brake) took some time, but basically, it is just 12V DC directly to the motor and reverse it for changing direction. But I will replace both rear discs and a new set of brake pads on both sides as that side with the faulty brake pads was severely corroded. Maybe I will do a YT-video about it (at least the second side).
Looks like you haven't had the BMS update. My June 2020 Zoe had a SOH of 88% prior to having the update. After update the SOH showed up as 98.8% in June 2021. After 25000 miles and 3 1/2 years it is now 96.6% .
Thanks for letting me know. I think I will indeed double check this for my wife at its her car. I hope the BMS update is for free even when out of the warranty period?
96,68% ? That is suspicious if you exactly have the same
Thanks a lot - really appreciate what you give us all here.
I’m getting my OBD2 immediately
You are very welcome, glad I could share this with other people. Such a cool tool to have in your pocket, can make starting a discussion with a dealer so much easier this way. But I hope you will not need it ;)
it's O B D not ODB On-board diagnostics (OBD)!
Do you limit how much you charge? I remember a video by Matt from GoGreen autos where he said he looks for high mileage evs for friends and family, both because they are significantly cheaper, but also because the battery health is usually good on high mileage EVs. He reckons this is because cars that do lower mileages are often charged at home to 100% and left full for days. He says this is the worst thing for battery health, but high mileage cars usually spend much less time at 100%.
Hey that's an important one. Didn't realize that. For first year my wife charged to 100% always but now we don't charge beyond 80-90%. Unfortunately the Renault Zoe does not have a charge limit setting like for example my Opel ampera-e / Chevy Bolt EV
@@maximaalski I'm looking for a used 2020 Zoe at the moment. I just discovered something really interesting. On one dealer they have two Zoes that have done 60,000 miles / 90,000 Km. Looking at the dashboard pictures on their site, I did a quick calculation using the remaining range and remaining charge shown. It's a rough estimate, but those two high mileage cars both came out at 208 miles when 100% full. But they also have two cars that have done 20,000 miles / 30,000 Km, and by the same method they both have 185 miles range at 100%! Sure, I have no idea if the last two cars have recently been driven hard, affecting the range estimate. But even so, 208 real world miles from 4 year old high mileage car is pretty good I think.
I don't know much about electric stuff, but here in Germany you can request a full certified battery check from a dealer, they usually don't have it ready, but you can request it and they do it for free, because they want to sell the car. There is a very low chance that they scam you with these numbers, because they have to give you a certified check from a third party. But now to my main part, this certified check takes several hours, I don't know the details but I think they empty the battery and recharge it during the process and check all kind of things. So Im wondering how this little device would show accurate values after such a short time. I would assume that the certified checks would use the same tools, if they are accurate enough, so I also have to assume that this little device does only a assumption based on some of the current battery values and doesn't show the real health state of the battery. This point would also explain why some people comment about different values after an software update, a real health check wouldn't care about any software, because it is done with the battery directly and will always show the real numbers, no matter which software update.
Hey thanks a lot for your comments. I'm also definitely not an expert. I believe that the OBD device with the software that monitors different aspects of the main battery is a good compromise. It puts some of the power back in the people's hands to measure some of it themselves. Then if they see something abnormal bring it in for the full testing you suggest. I would most certainly trust the Germans with this and the certificate approach 😀 I was shocked that my wife's Renault Zoe dealer does not want to update the BMS for free. They want 75 EUR for it or that we purchase some accessories and they give it then for free. I'm going to write Renault directly about it. What do you think? Shouldn't a BMS update always be included and pushed to the car for free. Since it is responsible for monitoring the main battery and how it charges et cetera? Have a great weekend ahead 👍🍺
@@maximaalski We have inspections which cost money where they check general things, this also includes software updates, so Im not sure if or how much it would cost us to just update the software alone. But I agree that 75 for a software update is way too much, The BMS software seems to be buggy in some cases, so it should be free. Maybe you have to word it differently, instead of asking about the update, complain that the battery (or range) is too low and start to talk about battery warrenty and stuff, maybe they will get worried and update it for free :D
The measured SoH may be incorrect. Try calibrating it. Drive the vehicle until it reaches 1% charge. Then, park in front of a max. 11 kW charging station. Set the temperature to activate the air conditioning compressor, and wait for the vehicle to shut down itself. Let the car remain locked for 1 hour. Then, connect the charger and wait for it to reach 100% charge completion. Afterward, you will see the true SoH value.
Hi that's indeed a very good tip I haven't thought of yet. Basically run it to complete zero and follow your steps. I will give this a try soon with my wife's car and see what happens. Thanks!
Generally manufacturers recommend below 10% then to 100% but I guess the lower the better. And to do this every 3 to 6 months
I know Tesla do, and MG
Tesla bjorn ( bjorn nyland) has just posted 3 videos about this and a cupra born, this didn't work in his case but I suspect it could be a faulty battery pack in the cupra.
@danuk2005 Thanks for the comments and reference. I will keep on doing this in the Renault Zoe the results are still there. Not sure why in my Opel Ampera-e I did not notice anything again first time maybe I will try it again 👍😀⚡
Good point; but this method will not take in to account the losses from charger to the battery which is perhaps 5-10% (if I haven't missed your point)...
I think degradation measurement is very difficult and only an approximation is possible and I will propose another method:
If you charge your car 20 to 80% say five times which makes 300% over the period (assuming you've zeroed the consumption at the beginning) now read your car's total (drive and accessories ie a/c etc. - Megane Etech seperates these two so you need to add) consumption meter then divide by 3 for our example case you would get a better battery capacity measure; I think. What is your thoughts ?

@gokcemuratozaydn799 Hey thanks for your suggestions. This is good and worth trying too as another means of checking and monitoring this. These data combined with one's own observations about how the range developed can help convince a dealer to check your car under warranty. I also noticed an improvement in range after I fully charged the Zoe battery then drain it to zero and then recharge it to full again. The range stayed and was probably there due to some recalibration of the battery. Thanks for sharing your suggestions here with other viewers!

My car is Zoe r135 2020 , at 78.000km . Soh is % 94.75 . This number is really bad , but my range is still same as factory data.
Thanks for your confirmation on this. That's same car as my wife's but with more kilometers on the clock. It seems like this is just a reference number, but more parameters are required to interpret the battery condition and degradation. How about in the winter when it's cold. You have still the feeling the range is equally as good there as it was when you got it?
@@maximaalski In my opinion, there is no change in the range for now. only the battery health values seem low.
Is there any progress on this situation? In some forums, it is said that the ACTIS software needs to be updated.
Not yet from my side. It's my wife's car but she agrees next time we will force the dealer to update it based on all the useful feedback we have received here. The update is essential and should be provided to anyone free of charge by Renault. Battery management software updates are in my opinion an integral part of the car.
Hello, thank you for this very useful video. I have just bought a 2020 Zoe R135 ZE50, (23000 MILES/37000km) and shocked at the numbers in range at full charge. I've ordered a cheaper OBDII device, hoping to get some insight on battery SoH and software to improve it?
Currently - In ECO mode, 168 miles on full charge. It was 148 not on Eco mode. It's not summer but it's still between 15-18 degrees here, so absolutely not winter either.
The car got delivered today, is there anything else that I need to be thinking of when talking again with the dealer?
Thank you
Hello you're welcome. I would check with your dongle and download the CanZe app for Renault Zoe car from the Playstore or Apple Store. Do a check for battery state of health when charged full. Then discharge complete and recharge to 100% and check again. If you have the feeling the range is too low I would present the battery state of health figures you found together with the low range to the dealer and demand an inspection since the battery is under warranty still. Also an upgrade of the BMS system could be done free of charge if that is necessary. What really helped me is the complete drain to zero percent (drove it to 2 percent parked it and did the rest to get to zero with airco full blasting on a safe spot). And the recharge via the home socket all the way to 100 percent. I got somehow better readings and a bit more range consistently. Let me know how it goes and I hope it was helpful. Drive it around and drive it normal and empty a few times and it should be better with the range. If in doubt go to the dealer and write Renault customer service in your country with a formal complaint. Good luck and enjoy the new car .. I'm sure all will be alright we love the Zoe and is very reliable too 👍 By the way some people here wrote some very good comments and suggestions worth checking them out!
I havnt got a ev but interested in one for a future buy.
I regularly check the SOH of my sandero car 12v battery so i wonder if the SOH that you are checking is the 12v battery which operates lights etc in the car and not the main motor battery . I would anticipate the voltage drop that you are showing from the 12v battery and anticipate replacing this as part of normal maintenance around 5 years just like a non ev car
The EV 12v battery charge is relenant is that it can show an engine fault I understand when it gets too low when in fact the main hv battery is perfect.

Hello thanks for your message. I can highly recommend an EV. We have an 2019 Opel ampera-e for longer distance (65 kWh) and a Renault Zoe (52 kWh). The Zoe statistics shown in the video are from the main battery pack and state of health. The 12v starter battery needs to be checked separately, but I would check it rather with clamps on the battery itself with a conventional reader when the car is turned off and left idle for 15m or so. I think that statistic would be more reliable than via the OBD tool. The car recharges the 12v periodically when plugged in or left idle. But My 12v battery is now almost 5 years old and I will be replacing it as a precaution probably by the summer. I always drive around with a booster battery pack in my trunk just in care especially for loner trips not to get stranded somewhere. Just common good practices as with a normal car. Have you already decided what type of EV you're looking to buy? I hope you will like it and let me know if you have any further questions
Take care and happy new year!
What you check on the 12V battery is the CCA and the steady-state voltage. Those two figures give a rather good indicator of the state of the 12V battery. I have so far not read anything about problems with the ZE50 12V battery (if not the result of total neglect). The onboard 400V/12V charger has a 200A charging capacity and has very high efficiency combined with smart charging (also temperature-dependent charging voltage). On the ZE40 it is a rather different story. 400V/12V charger with only 100A capacity and a constant voltage charging scheme so overcharging in summer and undercharging in winter conditions. The ZE40 only charges the 12V battery during driving and active charging. Never when the charger is "only" connected, so having the ZE40 just plugged in for a few weeks and not used may destroy the 12V battery...
Hi Folks.
I am about to Check my Soh soon. (R135, 52kWh, 2020, 29tkm)
When it comes to updating the firmware of LBC, what was the Price for such Update?
I read some Blogs which stated more than 500€ !?!
Hello unfortunately I don't know this but I'm sure there will be people here who commented under my video that know and will comment I hope to help you with this. Let me know and please share if you know. One could also mention that the range has dropped and less battery SoH during warranty period and maybe then they will do it for free? I will try this trick during next service interval 😁
It was free, but took time and effort to convince dealer. The symptoms in my case, May 2020 Zoe were: 1. Low SOH like 88%, 2. Lower range, 3. Huge time to reach from 99 to 100% SOC (like 30-45 minutes..), 4. Huge predicted range change between 99 to 100% SOC. All these reported and documented issues helped convince dealer to apply BMS update. After BMS update SOH went up to 96%, and range went up and charging from 99 to 100% SOC takes just couple of minutes. Good luck
@matejmraz8122 Thanks for sharing. Great to see the improvements after the update!
Hi. Do I have to buy the paid version to see the battery life? Because after connecting and selecting Zoe, it shows me an empty field in place of soh. . Thanks
Hello no you don't have to. I use the free one only. Maybe depending on your model and year there are several connection profiles in the app for the Zoe. I suggest playing around with the connection profiles for Renault available and see if one differs from the other. I hope it will work for you!
Hey
I have got the same car, only a couple of months younger and 33000km. I have measured the SOH over a couple of years using the CANZE - app., extracting the same data as the CAR SCANNER. Over time SOH has gone from 98% (spring 21) to 86% (winter 22) to 95% (summer 22) to 88% (winter 22) to 97% (spring 23) and now 92% (summer 23). So I dont find it very reliable. I have for 1½ years calculated the SOH : Energy (kWh) when full (green light at the socket) divided by 52 kWh. The results from these calculations also varies with seasons but are generally higher as the measured SOH's - last calculated 97% vs measured 92%.
Hey Jan many thanks for sharing this and your experience with the measurements and actually interpretation of this SoH number. Quite amazing to see all the fluctuations over the years and especially the seasons. I will actually try out your strategy here and see what numbers that produces. Did you have to drive the Zoe completely to almost down to 0% to get the best readings or this is not required? Also curious if you ever had a discussion about your findings with the dealer... Did they say anything about your investigations, or did they do an update of the BMS? Many thanks for the feedback and have a nice evening.
@@maximaalski H
Hey Maximaalski. I have not talked to the dealer about the issue - I dont think it would be to much use. I did not drive down to zero. When calculating the SOH I used data from Canze showing availible energy (kWh) then charging to finish divided by nominal capacity (52kWh). I found a relation between battery temperature (°C) after charging to full and SOH: SOH= 0,4696 x temp. + 87,644 with R^2 = 0,63
Have a nice day🙂
Cool! I will try it out, thanks so much for sharing this is great info!
Do you know if your Zoë is on the latest BMS firmware, (I couldn’t get that bit to work on canZE) but maybe worth investigating. My dad has a 22kwh Zoë 6 year old with 98% SoH.
My concern is yhe obd2 you recomend clearly states not suitable for hybrid or electric so if this is the case are you seeing the auxiliary 12v battery condition?
Hi I actually have never used my MX+ from obdlink (yet) to check the 12v battery status condition. Only used it for checking battery State of health and main traction battery stats. This works perfect on both my Opel Ampera-e (Chevy Bolt EV) and my wife's Renault Zoe (both new electric cars from 2020). I do believe you can pull 12v battery stats from it, actually I can do this and take a look for you and send you some Screenshots. I'm quite curious myself as now my 12v battery is 4y old. Perhaps need to replace it as a precaution. Another way to check would be with traditional clamps and voltage readers. Would you like me to do that with the MX+? Specially what 12v stats are you looking for... To determine whether the 12v starter battery still has decent voltage? Best Regards , GJ
Battery state of health BOH are tests used for both the car batteries . The 97% you have quoted would be about normal for the 12v battery. are you sure you are measuring the right battery .
My SoH statistics show up right underneath DC battery capacity 47,78 kWh in another test. Then right underneath is the Zoe DC battery State of health showing 90,19% in another reading I did. Although 12v could be read with the OBD I would still recommend a separate reading device with clamps on the 12v battery poles when car has been left idle for some time. What do you think can you get reliable readings for the 12v with the OBD only? I always drive around with a 12v battery booster just in case I long trips. Will be replacing my 12v now in my opel ampera-e as the car is almost 5y old
Zoe from June 2022, now 23000km, SOH 97,2%
That sounds like she is one very healthy Lady 👍🚙
Hi. When measuring the battery status does the Zoe first need to be fully charged?
I believe this is not required. Mine in the video was not charged to 100%
Hi,did you already have an BMS update?
Hello Josh, I havent checked yet the BMS version in my wife's 2020 Renault Zoe, but I'm going to do that one of these days with the OBD reader, then check online in the spreadsheet I found if it is the latest BMS. If battery SoH is again like this, I will approach Renault Zoe to update the BMS of this is not the most up to date Version in the car. I guess this would be the best way to approach this, what do you think? Have you had a drop of range and then did a BMS update that improved things?
@@maximaalski Hi,i have also a drop of range,i don’t know the SOH,i will ask the dealer soon for a check up,did you see this one; ruclips.net/video/iA3p7p3AF60/видео.htmlsi=lPpH2Mg5ANLkWpMQ

@Josh-du7ij Thanks for the video, I will watch it today. Yeah can highly recommend getting an OBD they are great for checking stuff and can even get you out of trouble resetting a code if you get stuck somewhere. Let me know please if you had a good feedback and experience with the dealer and what your strategy was convincing them to do the check. Good luck!
@@maximaalski ok,you will hear me when i know more.

Hello thanks for your experience. I honestly don't know but in a previous comment someone named Alper made a good suggestion to drive the battery all the way done to nearly zero and then recharge it to 100. Maybe I will also try this before I do more measurements
92% after 4 years - 57.800 km - ze 40
Thanks.... That sounds more or less what others have been saying and I've read. Has your expected range also gone done you think or haven't really noticed that?
91% after 4 years and 5 mounth - 87.200 km - ze 40
Thanks for sharing. That's a decent amount of kilometers. Based on what I'm reading this seems "normal" something around that number of state of health. You have almost same number as my wife's Zoe. I wish it would just be a 100%. Have you also noticed the almost 10% reduction in range or not really?
no. because i learn how to drive. and i use for summer MICHELIN
E·PRIMACY tyer. i usualy use 11 kwh charge. summer consumtion 10.9 . winter 18@@maximaalski

Hello, what car do you have and did you search for "health" only?
@@maximaalski I have a zoe. Yes, I tried to filter by the word health and the option does not show up
Sorry to hear that. Maybe something updated in the app that I have suggested in the video. I will try again myself soon to see. I can also recommend the CanZE app that a lot of Renault Zoe drivers like and also allows you to view OBD data via the dongle
@@maximaalski ok, thank you!
3.5 years, 48 000 km, my SoH is 95.61% so 4.39% degradation
Those are very good numbers and low battery degradation!
Very helpful Thankyou.
You're welcome. I hope this works for you too and unlocks some extra range and better estimates.
Ze40, after 8 years, 110.000 km, 81%
Impressive Zoe driving! Do you find the range reduction an issue or are you not that bothered by it? I recently charged to 100 and drained to zero and then again to 100 and got quite a bit of range back 👍
@@maximaalski I use it on urban and interurban trips. The autonomy it provides me is more than I need. I can also enter the city center and park for free or with significant reductions.
Please make this correction - it's OBD standart and O B D device On-board diagnostics (OBD) not odb :)
I know :( I found it very tough for some reason to pronounce it the correct way. Whatever I did it just flew out in the wrong letter order. But I've been practicing and in the future I will try not to mix it up any more.
Toyota Aygo no loss of range in 13 years......😮
Haha 😂 Yes Barrie thanks for rubbing that in 😉 But you are very right! Current EVs are really great but this uncertainty about how battery will degrade and hold up over time really needs to be dealt with by the industry. If you read the guarantee most ev companies say something like 80 degradation over x amount of years. If you ask me it should be no more than 10% or rather zero like with regular cars.

Needs a BMS update for sure!
I think so too... Getting it later this year when up for maintenance. Did you get it too?
dealer can't do shit about your battery, that's the probleme about EV
Agree, they will try to prevent you or make it as difficult as they can for you to claim the warranty. Luckily there are now more certified companies that can test the battery and generate a report used for escalation and claims. A great way to start is to test it yourself too if you suspect something. I hope you have not had a bad experience yourself with the dealer about this topic?
Its soo funny how you keep saying "ODB" instead of "OBD" :D :D :D hahahahaha ....but good advice. Cheers
Haha, yes I noticed this too. Very difficult I finally got it right but now the video is already out there. Glad you liked the video. I love having an OBD available in case I may need one 👍
That's French quality. Should have bought a honda or toyota.
Maybe.... But this lithium battery degradation seems to be a real problem for all car manufacturers. I think it is misleading.
@@maximaalski You are right. But i think the problem is that most people with an electric car drive 50 miles a day from house to work and back. That's let's say 10% used. Still, people see a free chargepoint at work? Plug it in. Juice up to 100% again. Back home with still about 90-95% charge on the home charger. A trip? Turbocharge in 30 minutes. I say, if it's bad for your phone, it's bad for your car. Same batteries, just a lot bigger.
Hmmm, volgens mij had ik ook in Nederlands kunnen reageren. 🤔
Ha, dat klopt inderdaad! Ja ik begrijp je punt. Wij zijn gek op onze elektrische auto's, voelen ons alleen misleid doordat die standaard Battery degradatie plaatsvinden. Ook al is het binnen het acceptabele niveau. Met een brandstof tank had ik niet na 3 jaar 10 procent verloren. 10% op een relatief gemiddeld bereik van 350km is 35 km bereik eraf. Ik had verwacht dat dit soort cijfers pas na 100.000 km zouden optreden, niet al zo snel!
