A note of those top 5 EVs that have the largest depreciation, 4 of the 5 had huge price drops. The price dropped on some Tesla models by $30K, which obviously dropped the resale value of those that bought them when they were much more expensive. The Chevy Bolt, bought new, went from $37K, in 2020, to $26K -- so again, a reason for a huge loss for people looking to sell. The Nissan Leaf is an issue of outdated technology, for charging it uses a ChadeMo plug, which never really caught on in the US. On top of that, it doesn't have a real cooling system for the battery (it is just air cooled) which causes issues with the battery in hot climates, causing used buyers not only to have to worry about how to charge their Leaf (other than at home) but also if they battery might fail soon.
It's also worth noting there are a lot of cars, not just EVs, that have had a lot of depreciation on the used market -- and a lot of it was due to the high prices car prices during and after the pandemic, so popular cars frequently were sold for thousands over the MSRP, and as supply has caught up with demand prices have gone back to normal (leading to huge depreciation on some models). For example, the BMW 7 Series has depreciated 62%, the BMW 5 Series at 59%, the Cadillac Escalade ESV at 59%, the BMW X5 at 58%, Infiniti QX80 at 58%, Jaguar XF at 58%, and Audi A7 at 57%. It isn't just EVs; just with EVs it is some of the top selling cars.
I note that EVs aren't the segment that depreciated the most, despite the huge price drops some models had. Also, if you remove vehicles like the Teslas and the Bolt, cars which had huge drops in MSRP, EV depreciation drops down close to the overall rate.
