When we bought our EV in the middle of winter we had the battery tested first, and we were told it was 89% of original capacity.
But inspired by my wife telling me about this article, and having to make an about 25% charge today, I thought I'd try to calculate the capacity from the information on the charger (Zaptec).
This is probably not the most accurate way to do it, but I was very surprised that the result of my calculation is that the battery still has 99% of the original capacity!! Even if that is 10% off, it means it may not have lost capacity in the 9 months we've had it.
Maybe it's because conditions today are better than in the cold of winter, where a garage even though it is indoor gets a bit cold.
And today was probably near perfect conditions with 20°C.
Our car VW ID.4 77 kWh battery, is nearing 5 years old, and 130.000 km. But the battery seems to be in very good shape. 😎
Electric Vehicles
Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

Thanks for the article. I'm glad the newer EV batteries are doing well.
Just curious, is there a good/cheap used EV car or small SUV to look for that has the ability to do small battery repairs and has good longevity? Something that sells cheap since it's a few years old, but still has plenty of life left and can be repaired seems like a fantastic option in today's market.
Avoiding Tesla, I'm guessing the Bolt might be a decent option?
I know that our VW ID.4 has 12 battery modules, and a bad battery can usually be fixed by replacing a single module. If you are lucky you can even get them 2nd hand. It's still not dirt cheap to fix, but it's a long way from other brands where a bad battery can mean the car is essentially totaled. AFAIK it is about $ 1000 USD to have one module replaced.
The VW ID.4 is a very good car IMO, but IDK if you would consider it cheap?
Not exactly what you’re looking for, but something to keep an eye on. The slate truck is under $30k with roughly 200 miles of range. It remains to be seen if it’s any good though.
