Only tangentially related, but I wonder what the expected battery lifetime drops to when you factor in crashes. You mention that the cells might last 500,000 miles but is that really relevant if you're likely to have your car totaled before 200,000?
Are there diminishing returns if you are a company working on a million mile battery since virtually no vehicles will make it that far?
I am speaking as someone who has had three cars totaled before 100,000 miles (none of which were my fault!)
- cbo100 4y agoI imagine most of the longevity research is actually being done for the stationary battery market. The fact it carries over to vehicles is just a bonus. Besides the salvage value of a battery pack would be huge, so I suspect a battery would be about the last piece of a car to end up on the scrap heap.
- wumpus 4y agoThe point is that the worst quality studies do assume that the battery ends up on the scrap heap, way before the car itself does.

- Robotbeat 4y agoTotaled EVs are a great source of second-hand battery modules, used either for fixing broken batteries or even for grid storage. Lots of commercial vehicles make it to a million miles. Those are the ones that will want the longest lived batteries.
