Tesla model 3 LR 2021 with 257.000km (159.600 miles) on it. degradation 7% That nummer is from the test made in the tesla service menu. And I did pull number from the OBD to scan my tesla. And I also use teslafi. All 3 says 7-7,5%
@@korbenDK that just proves what I found out, that degradtion is more with age on Tesla batteries rather than mileage and potentially fast charging. Can you share your number of KW AC and DC charged please? 👍👍
@@chargeheadsuk iam at work atm. But the last data i have on my phone. is from 13. aug. so around 2000km ago. DC= 8498,1 AC = 44571,7 Regen= 6295,3 I did charge to 100% 97 times so around 2 times a month. and 1415 times to 80%
@@korbenDK well there seems to be mixed content out there ref DC charging effecting specifically Tesla batteries. Its interesting to see that clearly majority AC charging has looked after your battery. Thanks for the info 🙏
@@chargeheadsuk yes i see many saying that test shows that fast changing is no problem. And the funny thing is that I did talk to a company who renovated or replace EV batteries. And he did tell me that he has a lot of taxi drivers getting a battery replacement. Because they use fast charging all the time, and sometimes many times in a day. They don't last that long. I'll say even some reports says otherwise. Fast charging is more damaging to the battery that slow charging. And for me it's logical because of the heat difference...
This goes along with the study that just came out that said for degradation is averaging about 1.8% per year. This being a 5 year old car would be about 9%. They also said that mileage didn't seem to matter.
The final charge to 100% takes a bit of time even though the app says 100%. I think it's performing a final cell balance which takes some time to complete and is the reason the screen is off.
Seriously, the sun is not going to crack the roof glass 😂. I never use cabin overheat. If you think about it, it's more likely to crack with a massive temperature differential cold inside and hot outside, not that it will anyway. Anyway, got my test running and will be interested to see result. Car has done 68,000 miles
You only test degradation by charging and discharging, so Service menu test is the best in terms of accuracy. And only test against the nominal pack, BMS will adjust buffer based on degradation to preserve maximum range. That's why with degraded battery you better not go below 0%, but you can with a new pack
Comparing to the original capacity is definitely the right way, otherwise its easy for a slightly more unscrupulous manufacturer to just throw in an excessive buffer so they can claim to have "0 degradation (for the first 100k miles)" or something similar to feign superior reliability but at the end of the day the other car without such a big buffer but a better chemistry, construction, cooling system, management algorithm, etc... that does see degradation (but gradual) during the first 100k miles might actually stay above 70% much longer.

Is the rear glass breaking a real possibility if you don't have cabin protection on? I've already just got the roof shades but thought the cabin protection thing was a myth!
@@rolandmoore9527 I've not used it, however heard good things. It woykd be interesting to do it on mine as a comparison.So if anyone has it and lives in the Northants area let me know
@chargeheadsuk I do have it, and I could see a day trip looming in a few weeks' time. It says I can add a second car, but the set up needs to take place close to the car since it commicates withe car and then needs to be validated. Let me know if you do not get a better offer.
@@whitey5000 same as mine. I found out after talking to a specialist that Tesla batteries tend to wear just as much with age rather than miles. So i recommend to buy on price and age. No point booking it in IMO. I hope you're enjoying her 👍

Just out of interest, when you say that the range started off as 310 miles is that real world or WLTP?
@@aquanick2001 thats range on the car, however there are so many factors, temp, speed its hard to call.
