I am under the impression that battery trains do not last anything like that long - am I misinformed?
Doesn't change the maths much, but curious
- cbo100 4y agoMost EV manufacturers are offering around 8 year/160,000-200,000km warranties on the batteries. So not 200,000miles. But definitely covering the average usage pattern. And not all will last that long, but the majority will. And potentially the worst case is just degradation - I.e. 200km range instead of 400km range, so still quite useful for a variety of use cases even outside of cars.
- freshpots 4y agoYes, current EV batteries (not the old Nissan Leaf ones without active cooling) are projected to last as long as 3 million kilometres: https://youtu.be/7DYknTVskTw?t=325 https://youtu.be/7DYknTVskTw?t=325 https://www.greencarcongress.com/2019/09/20190927-dahn.html https://www.greencarcongress.com/2019/09/20190927-dahn.html Dahn’s “million-mile battery” detailed in open-access paper in JES
- coryrc 4y agoWarranty is to some percent of original capacity, like 80 or 90%. Then you have another few hundred thousand miles for the next quantum of degradation.
