A $20,000 EV?, page-44

Rubbish, all EVs have active temperature and charging management these days (although not so sure about that $20K NIO) so the majority of batteries will be better than 80% of new capacity at 8 to 10 years (200 to 400 000 km) and gradually decline after that if they aren't abused. Most decent quality EVs will still have useful range (more than 60% of original) at 20 years (400 to 600 000 km) by which time it is likely the rest of the car will be feeling its age as well. The big difference will be the maintenance costs for a well looked after 20 year old EV will be way less than an equivalent ICE car.
