My Skoda ENYAQ RS has some charging problems! Strange SoC behavior and wrong charging limit
HTML-код

- This is an odd phenomenon. When plugging to an AC Charger my ENYAQ loses a couple percent of State of Charge....just to add them later on. What is happening here? I tried to find that out. Also sometimes my ENYAQ sets the charge limit to 100% percent...and I even caught that on camera!

Please make a tutorial with the OBD adapter👍🏻
You plug in OBD and use Torque. It's not ICE science to set up a monitoring environment for a car on your phone. Well unless you like a walled off garden that's walls are starting to fall like the Berlin Wall.
I set my 85x to do a 80% charge, and overnight it charged to 100%….no idea why
I now have 3.7 and it turns out to be a mistake. Off-peak scheduling from intelligent octopus via my Myenergi Zappi charger no longer works.
When charging from my solar panel excess, the car randomly stops the charging and only restarts when I unlock an relock the car.
My advice to everyone with ME3.0 is DON'T UPDATE until Skoda have fixed the problem.
While this might affect you if you only charge from the grid during the day, there may still be other serious charging issues.
I'll add that other owners are experiencing the same issues.
NIce video. I would like to see a video about car scanner. Mainly the best dashboards to use ewith an EV!
I've noticed when using the route-planning with the skoda app and have it set to 100% starting SOC. The car sets the charging limit to 100%. I have the 3.7 sw.
is there a change in the charging loss percentage. kwh delivered from the charger vs. kwh added to the battery, when this happens, and when i doesn't (or you charge to 100%
I think that with so many battery cells there could be post charge variations due to temperatures of individual cells . I'd guess that the batteries are split into groups of cells for monitoring so the software can't access the finished state of charge until everything evens out. (only a guess - I've got no expertise in battery management!)
Interesting. I have a 2022 Enyaq on ME3.0. I have no problems with charging currently. I am getting an update to 3.7 next week and I'm concerned about overnight charging via my energy supplier octopus energy. They control my Myenergi Zappi charger remotely and will be turning the charger on and off for several slots overnight.
Currently it works fine. I'm hoping it still works after the update. 🤞
The times my car changed the charging limit to 100% by itself was after using the app. I think 2 times it was after starting cabin preheating via the app but it could be a coincidence
It would be good to know which OBD adapter you are using - and also where the port is on the Enyaq as I've heard it may require some moving of trim?
No trim needs to be removed. Did a video on OBD a while ago on my German channel. Will do a new one in English. OBD port is on the left side of the steering wheel (left driver) and mirrored when right driver down where the pedals are directly under the cockpit. Cannot miss it because it's shiny purple :)

Have an 85 -24 with the same issue that the charge limit sometimes is set to 100%, despite battery care mode. But I haven't noticed any overcharging...yet.
All lithium batteries need to be charged to 100% once per month to allow for maximum performance. If not done, performance will go down and wear will increase. After this 100% charging, performance will be restored.
To me it looks mostly like a software/communication issue. The problem lies mostly in the GOM calculation part. The same can be said about battery care mode. I also have this when I charge with ‘Charging locations’. I can set a timer with specified SOC, but it won’t work, it just charges to whatever it likes. 😂
GOM is always a guess for the BMS, but I think this will be fixed by a Over-The-Autohaus update.
The car won’t overcharge, it always stops charging at a certain Cut-off Voltage.
Very strange behavior Matthias🤔 Since the Carscanner app (pro version) saves the data while recording, that could give some more clues about what is happening at the Cell level and other parameters of the battery and the BMS. I don’t know what exact BMS value (name) is displayed on the Infotainment display, but that might also be helpful information. The fact that it’s different from what you showed is strange also. Looks like a different parameter.
If I remember correctly you also did some analysis using an export to Excel in a previous video on the OBD adapter and the App? Maybe that will give some clarity since you can plot multiple parameters of a charging session in one graph.
Charging at BP pulse stations fast chargers In Northern Ireland is impossible … something to do with their software…. And confirmed by their engineers
Maybe SOC changes when battery pack gets much colder/warmer? Stellantis EVs show less energy in CarScanner when battery gets cold next morning (while SOC remains the same). Also you might want to check the Cell Voltage Delta mV, for any faulty cells.
Did this yesterday and today and grabbed the values...will post an update. But Batteries stayed same temp and same voltage yet a drop auf SoC when plugging in. Car was not moved for over 36 hours.
@@electrifiedspeicher One of the preloaded dashboard screens shows histogram of all cell voltages, very easy to spot a bad cell.
Very interesting. I have a similar issue with my 2019 Tesla model 3, the range would drop by 2-4% at end of the trip but usually will get the same percentage after charging. Have contacted Tesla service and suggested to put car into sleep (i.e. no charging for a few days), however the problem persists. Will contact Tesla service again if the issue is getting worse or in a few months time
Yes I have the same problems on my MY24 Enyaq
What sw version? I also have an 85x, and haven't seen this issue. (4.0)
Same issues with sw 4.0…still wondering when OTA to 4.0->4.1 Will be released.
All lithium batteries need to be charged to 100% once per month to allow for maximum performance. If not done, performance will go down and wear will increase. After this 100% charging, performance will be restored.
Well... according to my Skoda dealer it's a BUG....not a feature...
I would be really interested in a carscanner video
Why not take the car back to your supplier and ask them for a definitive answer?
Already scheduled but have to wait some weeks due to high demand of services in spring at my dealership
The charger is turning on function(pessimism). Any battery while being charged is going to show a higher voltage(float charge) than it will after removing the charger. If you need a 15min video to explain you that you need to go back to SDI for your daily commute, since you forgot to add in how much rubber the heavier EV is leaving on the road (increasing emissions).
Plug in hybrids all the way
Matthias do you have any news on the Enyaq 2025 face-lift any changes to batteries, infotainment. Ordered an 85x, my wife had a call from the dealer with an update, the dealer was able to look around the new Enyaq and a quick look on line you can see some long lenes photographs taken during testing. I think the newer models could be released later this year - what do you think?
At the end of the line its still a crappy expensive plastic no range car.. And yeah i'm driving one myself. I cant wait for all this ridiculousness to fly over and never comes back. Electric is not the future, it could be but they like to milk the cow too much
