Hi there! Thank you for the video. Is it ok to keep charging the battery even though my battery is only at 80-100miles? Will this shorten the battery life? Or do I need to wait until I reach 20-30% before charging? have the SR+ Rated @220miles.
Like Tesla So when you took your car to Tesla did they fix it? Or did you have to do all the recalibrating your self through charge techniques because my 240 mile model three only reads 221 and I just started charging it to 90% about two weeks ago from 80%
Marky Maarty You will not significantly impact the life of your battery if you charge up again at a lower SOC. At 5:08 of this video it explains the various SOC number of cycles. 75% to 65% and back is the best, 75% to 45% and back is next, and 75% to 25% and back is 3rd best. Even 85% to 25% would be just fine, and is still going to take 2,000 cycles to reach 10% degradation. 2000 times current SR+ 250 miles is close to 500k miles or 800k kilometres. The important thing is not to charge above 90% unless you are going to drive it down to below 90% right away.
Like Tesla Can you cover charging speed ata Tesla supercharger pls?
Had a battery replacement on my S at 140,000 miles. Charged to 100% daily, ran consistently down to 20%. What prompted the replacement was the car completely shut down with 34 miles of range left. Silver lining was that Tesla upgraded at no charge from 60 kWh to a 75 since they don’t make the 60 anymore.
Tesla Rocks. I was wondering if they gave you a new badge on the back Sean.
Chris Bates they sure did!
60 and 75 were always the same batt. Just a software unlock
Does it Matter not the early models. Was truly a 60.
Sean Mitchell I knew Sean would be here!!!!!
My 2015 Model S 70D is set to charge to 90% and I plug it in every time I pull into the driveway. (unless I plan to go right back out in a few minutes.)
The car has over 35-thousand miles on it and when I fully charge it, it still shows between 236 and 240 miles which is what it showed when new.
Tesla has recommended the 90% charge for as long as I can remember and since they designed and built the car it seems one should go with their recommendation.
:) Jeff S. and Elon M. know best. :)
Sounds like a opportunity for a in car app that recommends a charging and maintenance routine based on the cars driving and charging history.
Wonderful idea, though why not have it built into Tesla's own software?
@@mark-govers from what I can tell, Tesla tries not to build in complexity with their vehicle. I wish they would give us techie owners more access and information if we wanted it, but alas they want to keep it simple.
Great idea!!!
Thanks
This was a fantastic episode! Thanks for covering this!!!!
To be clear, what Kim is talking about here is the *calculation* of battery capacity, which is not the actual battery capacity. The reason to charge to 100% occasionally is to reset the *calculation* , and also to balance the cells in the battery pack.
Charge to 70 or 80% daily and try to keep the charge centered around 50% during a daily trip. If you need to use 30% of charge in a day, charge to 65% and discharge to 35% before charging. That's a way to maximize the long term life of the battery pack.
Jeff Dahn suggested a daily maximum of 70%. Elon suggested 80%. Either should be ok. For long trips, start with 90% or more.
Tesla recommends charging every night. If your daily driving is a short distance, then set the maximum charge to 70% or less.
We have been driving EVs for more than 20 years and have studied battery technology informally.
Loanword Eggcorn good thing u cleared it up
You seem to be suggesting that we do not recharge if we only drive a little bit and the charge drops from say 70% to 60%, as an example. Is that what you intend? That seems to contradict Tesla's guidance to "always be charging." In other words, Tesla says to charge every night, even if you only used 2-3-5% that day. Given that they have published so little guidance on this, we should be cautious about violating what little guidance they have given.
Charge everynight is ridiculous especially for those that dont drive that much 10/ 20 miles a day and/or dont have a home plug
Very helpful comment! Thank you!
@@davidbryant2872 Charge every night, but keep the limit low, like 70% or even less, if the daily distances are short.
I always charged my P85 from 2014 to 90%. My rated km's dropped from 352 at 25.000km to 336km at 172.000km. So doing fine.
i would not follow your regimen, study up on lithium batteries
Love the channel. I just bought my Model 3 Performance a week ago and I can confirm they told me to charge it up to 90%.
Tesla S85 charged to 90% daily for 6 years, and 100% most weekends for long trips. 97% original capacity and no range loss in 4 years with this strategy. Ontario Canada.
What’s your maximum charge speed at a supercharger? Thanks
That great... We got a model 3 SR+ with only 41.9 kWh pretty much right after getting it... Warranty = up to -30% and I only am at -14% ... Not joking
Hi Kim! We have a Model X P100D that we purchased in June, 2018. Although we have a Tesla Charger at our warehouse, we primarily charge it every other night at the Tesla Super Charger down the street and we always charge it to 90% unless we're going on a long trip, then we charge it to 100%. After 6 months of doing this and 6,500 miles on the odometer our first FULL Charge in June resulted in 288 Miles now it's down to 287 Miles. And THANK YOU for the incredible videos we always look forward to watching!!!
I needed this video! Thanks for the research and clarifying.
do your own research on Lithium tech
When I first started having concerns was when I saw 217 miles displayed range at 70% slowly drop to 198 miles at the same 70%. After a few phone calls and follow-ups, I talked to a battery tech at the Gigafactory that looked at my stats from the car and explained that my shallow daily charges were not enough to get a proper result from the algorithm the car uses. He recommended to not charge every day unless I really need the range and to run the car down to about 100 miles of range before charging again. I started doing that and after about 3-4 charges, I was back to displaying 217 miles at 70%. I recently charged to 100% to take a trip to the Tesla Fremont factory tour and the displayed range showed 309-310 miles after charging the morning we left. I still plug in every day for the convenience of pre-heat/cooling of the car or if something comes up and I decide to add a few miles I can use the app to do so. That requires me to take the car off a timed start charge and stop it from charging when I plug in to let the range get down to 100 miles before charging but I can't argue with what works.
+JeffnReno -- Very interesting.
// We're probably all good to be varying the SOC, but occasionally maintain 80-90%.
Not sure if Tesla is like this but your range based on 70% could be due to your driving habits? For instance, your drain your battery energy and range faster driving 80 mph compared to those who spend hours in traffic and are slowly going 20 mph. Thus, Tesla is telling you how far you are going to go based on how you have driven the car over time.
@@ethanrichie7022 I thought that too since that is the way my Leaf works but I've been reassured that Teslas don't work that way and my driving habits are pretty consistent. My lifetime kWh has been 225 over the first 6000 miles and never changes. I stand by what I posted and it works for me.
Just found your videos today Kim and I love them! I'm a happy Model 3 owner but after 6 months there is still so much to learn. Thanks so much for sharing your experience.
Great video! Thanks for looking into this issue. i hope the video helps to prompt Tesla to formally publish some clarified guidance.
Thanks, Kim, for your dogged follow up on best Tesla charging practice. I have personally gradually found that charging my new Model 3 to 90% seems to suit my car best for my driving style and needs. You have just confirmed that what I have been doing is not only not damaging my car, but is nowTesla recommended. I also look at it this way-- My 3 is now fully charged & ready to take on whatever the day offers me, emergencies included (fires, power outages, family emergencies). To be ready only makes sense. Additionally, with a 90% charge level, I can also have some spare power to have a little driving fun with my new Tesla friend! Thanks again.
Merry Christmas!🎄
I charge to 90% every night (rarely do I go below 50%) and my battery retention is great. I've had my model 3 since about March and it still has a rated (100%) range of OVER 310mi - it's like 314mi. Great video, btw. Loved the updated charge info from Elon, glad he replied.
Great information and I went ahead and took a couple of screenshots! Congrats on the website! I’ll be sure to check it out.
I hope to get 400,000 miles from my 2019 Model 3 ! Should be easy based on this, cheers. 😀
Great video, thanks!
Thank you so much for the information Kim !!!!!!
Thank you for making these videos they’re amazing
Unequivocally super informative ! Thanks You KIM, your vids are still tops !
Great video...I charge to 90% everyday and leave it plugged in. It's a new Model 3 Per+ with only 2800 miles but I am not worried in the least charging to 90% daily, especially with winter in full swing we can use that little bit extra!
I'd also like to add that if you drive a Tesla because you like how quick it is...the high state of charge does give you a bit more power. Brooks over at Dragtimes I believe it was showed no matter the SOC the instant torque is about the same however the sustained horse power as speed increases is affected...so lower SOC equals lower HP over the speed range and vice versa. Just a thought!
Damien Gambill I recall that Dyno video too, where an SOC over 80% did make more power. If I recall correctly, dropping under 60% really started to show a steep power falloff curve.
@@aussie2uGA Exactly...most people drive their Teslas and then some of us DRIVE out Teslas! I am definitely the latter so I like a higher SOC!
Thank you for this video!!! What great info, thank you for doing your homework and shareing your answers!!😊
Thank you for this, very informative and it was hard to find this info.
Kim talking data and Tesla makes me 😀
Now kiss
Ben's and Kim's are the best! Finally decided to subscribe! Can't wait to get my Model 3 early next year!
Lol your wife reading this comment makes her🙃
The emoji you were looking for is 🍆
What a creeper..
Great job on the video ! You made it concise and relevant, I learned a lot of useful info in a short time- thanks!!
WOW THANK YOU FOR UPDATED INFO
helps a lot
Fantastic round-up, Kim. Well done on the research, summary and details.
Great video very informative. I will watch it again for info later too.
Thank you for doing this research.
Thanks for this update! Awesome vid!!!
Kim,
I really enjoyed this video that dove deep into the numbers and batteries. Feel free to make more like this one.
Holy cow, thank you for deep diving into this and getting that data like teslanomics' Ben Sullins
Thank you, Professor Kim, for the learned discourse. The short version, as I see it, is that the battery likes to be between half and two thirds full most of the time, but the sensors require charging to 90% fairly regularly to record correctly. When doing that though, charge it and drive it, don't charge it and leave it overnight. Equally, it's fine to run it down to 10% or lower, but charge it up again straight away, don't leave it that empty for any lengthy period.
Congrats on the website! I love hearing your story!
Thanks for doing all the leg work Kim. 6 months, 22,000km, I’ve been charging 80-50% daily. 80% maxes out at 370km now. I’m going to do 90% nightly now and 100% every 3 months and will report any changes on a follow up vid. Good work.
What about the 2013 18650 cells? Still charge to 90%?
We charge our MX to 90% daily because my wife has a long commute. Never charged to 100% yet in our 6mos of ownership. I'll try it out to see if we have any degradation. Thanks for bringing up this topic!
BPRIME I have 10,000mi on the M3 now and have never charged to 100% either. The theory passed around was that the anode and cathodes physically expand/contract/change when fully charged or discharged. The going recommendation was keeping the battery between 85%-15% and it was happiest being stored around 50%.
If you don't need 100% it's better for the battery pack to charge to a lower level. Avoid extremes of both charge and discharge. Maximum battery life in the graph is all at 75% maximum.
really informative episode. Thanks!
Is this true of Model S and X? Or is it just the 3?
@@bayoneman and @like Tesla. Same question. Does this apply to S and X too?
I've got 10k miles on my 3 and have been charging at 70%. Charged to almost full Monday - I stopped charging at 301 miles and hit the road so I don't think I've had the issue. Nonetheless I am changing my habits. Thanks for this info!
Very important subject. Great post and love you wouldn't accept their explanation at face value and kept on digging.
Thanks! This is really great to know. I've been charging to 80% daily as I only use about 10% for my commute leaving tons of extra miles to allow for cold weather or unexpected errands. My Model 3 has always reported 248 miles at 80%. Now that it's winter in Seattle, I charge to 80% as soon as I get home then in the morning I turn the heat on before I leave and move the charge rate up to 90%. I don't have a garage so it helps to warm up the battery a bit so I have a little bit of regen. Is there a way to warm the battery faster? Even after driving to or from work I still have limited regen.
Great info. Question: Why is a headquarter approval needed for hard reset? I don’t get it!
Makes sense. I planned on charging every few months to 100%. I noticed this when I charged at 70% for a couple weeks and noticed reported less by as much as 10 miles. A couple charges later at 90% it came back to what I expected. It does vary even at the same percent a few miles. I originally thought of only charging to 70%. Even if the battery doesn't have memory issues like old battery tech, I can seen the same thing with cell phones over the years that frequent charging helps and not dropping below 30% often unless you need to.
I charge up to 80% each night and I come back with variable SoC, my car has 130 000 km and when I charge it at 100% I can drive 350km. I have a 85kWh battery in a 2013 signature model s.
Great video, good job sharing that info.
Thank you for the video (and your many others) and for the information. I'm glad to hear that Tesla was able to give you information and that there is a "built in" buffer to prevent any battery issues. Living and working here in North Dakota I keep my Model 3 (Jarvis) charged nightly to about 90%-93%. I've had the vehicle for 3 months, and I haven't seen any drop in the displayed range. Only during the cold weather (today it's about 10 Fahrenheit here) do I see a loss in range. , Only if I am not able to use the 120V outlet at work to mitigate the cold weather impact do I see any limits on range. This winter will be a interesting test to see how Jarvis will handle the very cold temps here.
I believe if you can set your charge timer so that the car finishes charging just before you need the car in the morning, you may get the best range. Reason being that the pack will be warmer due to the charging.
Also unless you actually need more range, charging to a lower maximum still may be better for the battery pack life.
Good luck with your web effort. 30K miles on our Model X. Loving it! The 6 weeks of waiting for delivery were filled with TeslaForum and LikeTelsa, and Tesla Bjorn. Thanks!
Thanks Ross!
One RUclipsr complains that his model X is falling apart after only 6 months of ownership, how are things going your side dear Tesla owners?
What's aTelsa?
M3 owner 6 mos with 14300 miles . I break up habits a lot. Sometimes charge daily 80-90%, occasionally discharge to 15- 20%. Range charge for longer rides every month or so. 90% soc fluctuates between 272 and 280 miles. Seems the balance practice to range charge then discharge to around 20% then over the next couple carges I will see 90% increase from 272 to 278-80. I do most charging at work 12 hour shifts but I never let a soc sit below 50% after a ride parked at home then charge the rest of the way at work the next day. Winter I plug in more often.
I’ve had my Model 3 for 2 weeks. I plug it in to 110v every night charging at around a 5mi/hr rate. That usually results in a full charge by the next morning unless I do more than a normal day of driving (less than 50 mi). I have been on 1 road trip where I did probably a total of 2 hours of supercharging but other than that have only used 110v at home.
I have not changed the “default” setting which has the max charge set to 90% (279mi/310mi). I haven’t spoken to anyone at Tesla about it so I hope I am doing the right things here.
Thanks for you work on looking into the best practices for charging to maximize battery life! I’m counting on 150,000 miles!
80% daily charging on my model 3, which displays anywhere between 248 and 251 miles. Good, informative video.
Damn my performance has 241mi on 90%.
Wow, 1 hour of editing to 1 minute of video. Husband is totally awesome and you make very interesting videos. Thank you
#SharingTesla
We have 5500 miles on our model 3 and we are glad that we got the long range battery. We have used a super charger 3 times on a long trip, we normally charge in our garage to 75% every 2 days or when needed. We have noticed that the cold weather really takes its toll on the battery range as we live near St Louis. Love the car.
The range in cold weather isn't really lost; it's just reduced due to cold temperatures. When the pack warms back up, it gets most of the range back.
@@LoanwordEggcorn , actually range is lost when you need to generate heat to keep the cabin comfortable and defrost the windows.
@@darrenfon Agreed, but the pack does not permanently lose capacity as a result, as long as the resulting discharge is not too extreme. What you're describing is a practical concern; some of the energy is used for heating the cabin (and the battery). I'm trying to say that the battery is not permanently damaged by cold temperatures. When it warms back up, its capacity largely returns to normal.
Live in STL as well, cold weather sucks and it has inconvenienced me a few times now. Afraid to take it on a short road trip in January due to the reduced range. Need a technological breakthrough or larger battery capacity to combat cold weather.
@@84corvan Tip: If you finish charging just before leaving on a road trip, the pack may be warmer and have more capacity.
Great info, thanks so much.
Excellent video. The 2170s are amazing batteries. The longevity is crazy!!
I’ve had my model 3 for about two months now. When I got it I was told that the prevailing wisdom was to charge it to 90% and that matches what the app says as well. They placed the line between daily and trip charges at 90% on the app too.
Hi Kim, I have been loving your channel since before I picked up my Tesla Model X. You and your hubby helped push us over the edge to buy it.
I've had my Model X 75D for a little over 16 months now and put about 22,000 miles on it. I've had TeslaFi capturing statistics on it from the get-go.
I live pretty much around the corner from you North of Atlanta so that's my typical climate (with occasional forays to Canada and South Florida).
My charging regimen is a mix of economic vs utility. I have free charging at work and I go into the office 3 days a week. So I use TeslaFi's scheduling to:
Charge the car to 90% when I'm at work and for weekends.
Charge the car to 60% all other times.
The net result is that I seldom charge the car during the week at home. I have 15 total charges to 60% for the past 16 months while I have 319 total charges to 90%
According to TeslaFi's statistics I'm showing:
1.86% degradation for my High Range vs. Low Range (238.21-233.85)
0.19% for High Range vs Current Range (238.21-237.76)
0.03% for Starting Range vs Current Range (237.83-237.76)
So... if I'm understanding your numbers correctly, your absolute degradation is 0.03% (range on Day 1 versus range now), but your range calculations have varied as much as +0.16% to -1.67% versus the range on Day 1.
@@bigdream_dreambig Yes, the criteria seem a bit arbitrary to me but it seems this is the best we can do.
It might be more accurate to average the numbers for each month or quarter to compare since that would soften the impact of a particularly negative (or positive) outlier kind of result. But the degradation appears to be slight enough that I'm not sure it makes any kind of difference anyway.
Also, all of this is predicated on Tesla's estimated range calculations being pretty accurate as well.
So I'm going to just go with the results TeslaFi has to offer and assume that will be good enough for my purposes. Basically it's telling me that I won't be stung the way I was with my early NiCd electric drill. :)
Found a perfect shirt for my son. Thx! Finishing Christmas shopping
Thanks so much!
👏🏻
Thanks for looking into this and explaining it. Takes away some “Battery anxiety “
We’re at about 9000 miles and have been charging to 85% basically since we got it. We do make trips of about 130 miles and back regularly and when we charge to 100% it says 310 miles still :)
redzombi2k lucky
Great battery information Kim! Thanks.
My M3 is also 6 months old, and I have about 9k miles on it. I've been charging at 90% every night since day one. I work about 2 hours from home. I have not seen any issues with the SoC, and still when charged at 90% it shows 279 miles. I live north of Washington DC and currently is kind of chilly around here and the battery seem to be behaving well. Great video! Thanks Kim
Thank you for posting this. I think it is helpful for new Tesla owners that will expect to see 310 miles of range when charging to 100%. My first time charging to 100% I only saw 299 miles of range. I think I need to do the battery balancing procedure as well.
Dtube31337 how do you do the balancing procedure ?
Great video Kim. I have a 2013 MS 85 that I purchased 9 Months ago with 114k miles and now have 125K miles. I was charging each night to 70% but will now change to 90%. Over all I have about 8-9% degradation but am going to run the recalculation test mentioned and see if it improves. Either way I am still very pleased with this car. Thanks-
The voltage curve in the middle is relative flat so the BMS can not use the voltage to calculate the state of charge.
in order for the BMS to learn what an empty and a full battery is, it has to occasionally be fully charged and fully discharge.
The owners manual for my EV recommends a full discharge/ charge every 3 months in order for the BMS to calibrate it self..
Model 3 LR owner for 6 months. 5200 miles. Charge at home with mobile connector nearly always to 70%. Always shows 217 miles. After about 2-3 days or 100 miles, I recharge. So the battery is always 30-70% full. Only before 2 long trips did I charge to 100% and the range indicated was 312 and 307. I don’t perceive any degradation, yet. An occasional charge to 100% followed by a discharge to 10% might be a good idea. I don’t know.
David Nizel
Same here bro! 6 months, 5000 miles, 1 charge to 100% where it stopped at 97% with 307 rated. I charge to 80% daily but only use about 10%.
jujitsuboy730 So you normally charge to 80% and then recharge at 70%? I only have 705 miles on mine as it’s fairly new but I’m so confused as to what the best practices are given all these conflicting numbers lol.
@@2CommaClub Best practice is to charge every night to 70%. If you're only using 10% of charge every day, charging to 55% would actually be better. The goal is to be centered around 50% and not go either too high or too low.
@@LoanwordEggcorn That isn't what Tesla recommend, is it? They say at least 80%, and 90% is fine also. There is no information that it is good to center around 50%?
Yeah, see this is what I'm talking about I've heard just in the past day about 5-10 different opinions as to what the best practices are.. I've heard drive to 10% and charge to 90%, go from 80--30%, go from 70%-25%, go from 80-20% and then every now and then go from 5% to 100%... now keep it around 50%... I don't think there's any best practice at this point lol other than don't go to 0% to 100% to 0% every time. At least we know that much! :-p
I have a 2015 Model S and a brand new 2018 Model X. The Model S has 108K miles on it with about 80% of the miles being supercharger miles. I travel a lot for business. I have only lost about 5% on the S. My charging habit is always to 90%. I can count on my fingers the number of times I charged to 100% I routinely discharge to 10% or less on road trips. When at home I don't charge every day. Maybe 2-3 times a week, because I work out of my home when not on the road.
Unless Tesla comes out with another Model S that I just "must have", I will continue to drive the S indefinitely. If they came out with an S with over 400 miles range, and or full self driving became a reality, then I would feel compelled to buy a new one.
Kim - I have to agree with you that the Model X is the perfect family car. We love it!
Thank you so much for the great information.
Haha as an engineer kinda figured this despite what I had read online about going to only 70%, batteries like being just below completely full and just above completely empty. Been charging myself to 90% daily since I got my Model 3 in September. Great video as always!
I had always been led to believe that 50% was the ideal but it seems that consistently charging to 90% doesn't hurt anything!
Hi Kim, enjoy all of your videos. Do you leave your Teslas plugged in when not driving them, or charge them as needed? I usually charge our Model 3 once or twice a week as needed.
When we purchased a year ago (Dec '13) they instructed us to charge to 90% for daily use and to only charge to 100% before a long trip when you would want the extra 10%.
I had the same "issue" of range loss and contacted my tesla service center. They were helpful and after cycling the pack one time, we were back to the new car range +2 miles. They told us to cycle the battery at least once a month and charge to 80% or 90% nightly. We have a MS P85 with 65K miles on her and had been living in the safe zone of 50-70% daily charge because of "things read on the internet" and yeah, just bumped her to 90%.
This is fantastic news for all of us that are trying to adhere to a “best practices” charging routine! But it begs the question why the screen inside the car still shows “daily” as a much lower range and 90-100% as “trip”. Think Tesla will revise the charging screens on a future OTA update?
They sure do need to update their screen and apps if this is true for model 3 BMS.
If this is accurate, it would be nice if Tesla sent out some updated information on this topic. I happened to stumble on this video (thanks!) but I'd say the widespread mindset was with the original statements. I have been charging to 70% each weekend (free weekends) and discharging throughout the week. If I am causing mis-calibration issues based on what was recommended at the time....that would be nice to know.
Krahnin I agree, I’m a new Tesla owner and I work from home mostly so I don’t drive much so I often go 3-5 days before I need to charge. And I’m still using a regular outlet so I’m only getting 4-5 miles of charge per hour so I’ve been going to the nearest Supercharger station to fill up to 70-83% most of the time. I’ve only plugged in overnight at home a few times (I’ve only had the car for 2.5 weeks). I’m really wondering what the best practices are. I’m definitely thinking I’ll need to get a Tesla charger installed but I was going to wait til my 6 months of free supercharging ran out in May.
I agree. Tesla has been so silent on this topic in their owner's manual that I have always doubted the various people who self-identified as experts and claimed that this practice or that would be good for the battery. I have always been very skeptical of people telling us to "re-balance the cells" and so on, because nowhere did Tesla ever say to do that or that there was any imbalance. So if there really is new guidance, or if the guidance is different for Model 3 than for Model S/X, Tesla really has an obligation to put out the clarification in some manner that everyone gets it -- not just via social media!
I agree 100%. They should put a video or infographic or even just some text on their website stating what the official best practices are. All we can do right now is run our own experiments but I'd rather just know what to do lol.
Tesla has been telling everyone to charge to 90% when the car is delivered. A least that is what have heard most people who have taken delivery has said recently. Everyone just thought it was better from what others have said in the past so they didn't listen to their recommendation, including me. I will charge to 85-90% from now on. At this point it seems to make more sense to not charge for a while and let it go down to 20-30% before charging as well. Then, like Kim said, charge it fully and discharge it down to around 10% every 3 months.
I picked mine up in late October and was told 70-80% for daily use; 100% only for when doing long road trips. That mimics the only high profile tweet I’ve seen from Elon on the topic until this video. It sounds like Kim has confirmed with them that this has a high probability of causing mis-calibration. I don’t have time to stalk Elon on twitter, so the possibility of missing a single tweet is high. I feel the responsible thing to do would be to send an official email to owners clarifying this matter since they have, on several occasions, released information contrary to what was detailed in this video and which will seemingly lead to battery issues.
Is it at all beneficial to charge at a lower amperage to "trickle charge" or just best to charge at full 48amp my Wall Connector is capable of?
Did you try the factor reset to see if it resets the calculation?
Ever since I got my Model 3 since september 19, I always charged my car up to 90%. I went to 100% once so far just before I traveled. So far the numbers are ok.
I always leave my car plugged too at home (I live in an appartment).
Love this video. Great info. Thanks.
So what about the impact of supercharging vs L2? I've heard mixed opinions about how much this affects the health of the battery. Someone should set the record straight on that one as well.
Thanks for this. As someone who knows this science well you had mentioned variables I never considered.i used to preach a range of 30-70% keeping your source electricity 40 amps and below for maximum life and for model s and x I stand true on this and Tesla recommendation to avoid any risk of battery replacement guaranteed out need to be keep your state of charge between 20%-80% and have most of your charges not exceeding 60 amps on the s and x and I assume it was a standard that model 3 was also held too. Oddly enough my habits have been 50-80 this meaning i should full cycle more frequently but with this from Elon I will try to get my batteries barely below 20and set limit to 85 lol
Tesla model 3 AWD 9/27/18 delivery. Car was factory set to 90%. Also instructed by Tesla keep the car plugged in while parked and charging to 90% daily. Now if Tesla service can get us in to fix the many delivery issues, ;)
So should we be charging each night?? I am having a issue with a new model 3.. I am getting about 50 miles only for 40% of batt???
Good lnfomation thank you.
Over 100k miles and NO DEGRADATION! 2015 Model S P85DL 103,082 miles at the moment. My vehicle is rated for 253 miles but this week after a trip (and the battery pack was all warmed up from the trip) I received 254 miles at 100% that night! This vehicle sees 90% charges most nights and not too many miles during each day but gets a workout twice a month that includes 100% charging and trips that take multiple supercharger visits. I couldn't be happier and can't wait to hit 200k miles to check the degradation at that point...
It sounds like the specific requirements to charge up to or discharge below to avoid inaccurate readings will just increase range anxiety more.
So, what are you charging it to every night after this new recommendation ?
And is the recommendation the same for Model 3 vs S&X?
Congrats on launching your web site! Great episode regarding best practices on charging the car. I've researched this and found so many different opinions and I'm glad you were able to pull the pertinent info together and even back it up with recorded historical data and recommendation from Elon! So 90% it is charging every night.
What's the best thing to do with Model S & X with 18650 cells? Same as the new 2170 cells or still follow the older advice?
We get the same thing on Zero motorcycles. The fix is an occasional run up to 100% assigns leave it plugged in for a couple of days (pick cool days). It's not needed very often, maybe every 3-6 months.
Big thanks for this... I have a 2018 S75D (now at 5k miles) and I've been charging to 80%. Drive about 80mi/day .. I never got the 259 the book claims; max is 252, but I lose 2x mi within the first 20 min of driving. Still the case. I got the car to 2% then did a full charge and no change, but only did that once. I'll start charging to 90% more often, see what happens.
Mehmetcan Karahan charge to 100% and down to 10% a couple of times and then the algorithm calculation for SoC should then be accurate. Repeat every 3 months or so
Love the vids, watch them all!
Thank you so much for sharing Kim! I appreciate your tenacity of going all the way to Elon to confirm the proper way to charge.
Thanks for including the range in (the much better) kilometres! 🙂
Model 3 has one of the most sophisticated battery systems in the world. The most important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN when you are not using it. This is particularly important if you are not planning to drive Model 3 for several weeks. When plugged in, Model 3 wakes up when needed to automatically maintain a charge level that maximizes the lifetime of the Battery. Note: When left idle and unplugged, your vehicle periodically uses energy from the Battery for system tests and recharging the 12V battery when necessary. There is no advantage to waiting until the Battery’s level is low before charging. In fact, the Battery performs best when charged regularly.
So I just got my Tesla and I'm curious say I run to the store and use only like 15 miles or so. Should I plug in my Tesla and recharge it to 90% or just wait untill the end of the day and then charge.
Duuuuude the merch is sooo good looking.
Great information! Thanks
Just changed my daily charging percentage limit from 80 to 90. I've asked Tesla the same question, still waiting for the response. So far, my M3 shows correct mileage vs percentage, we'll see what will happen with higher charging levels. Thanks Kim!
Interesting, so does this apply to model s and x chemistry also?
This has been my biggest question since delivery a month ago. Living in PA winter has set in and I am trying to precondition the battery. I set my charge at 80% to start every morning at 5am but I don’t always finish the charge if I get out the door on time. I really wish there was a definitive answer from Tesla. When I saw Elon’s tweet I was happy that I was doing the right thing. Now after watching your video I have no idea again. When charging does finish, 80% is consistently getting me 249 of estimated range so it seems in line. Any-who thanks for the video keep up the good work. I will check out the website to find out why we never hear from your hubby. We want to hear bantering!
I have always charged my model 3 to 90% from day one (may 24th 2018)
