Our 8 year old 2015 Kia Soul EV is about 15% degraded (on the worst cell, which could be replaced individually btw). Battery degradation is generally fairly linear between 100% to 70% SoH. So I don’t see why I shouldn’t expect another 8 years on it. It depends on how much it is driven of course. The mileage is probably a bit below average on that one. I have a short commute to work. We did some road trips in it though. You gotta take into account that old EVs with small batteries will probably often be used as a second car, and so used less often. That’s the case for us since we got a newer bigger car as our family grew. We don’t take the Kia on road trips anymore and my wife takes the bus to work.
