It’s perfectly possible to swap faulty cells in an EV battery, but it requires specific skills and tools. Most shops don’t bother. It’s easier to swap the whole battery.
- ZeroGravitas 3y agoSwapping the whole thing is reasonable if you get the full value of the "dud" battery. There's specific factories that buy and refurb these, only replacing specific cells and/or modules and then selling them on again as replacement parts. Even the totally mashed parts (from a crash perhaps) have some residual value as scrap. Fairly certain similar has happened when I've mailed off Xboxes for warranty repairs. I've got someone else's refurbed unit sent to me and mine then enters the refurb process before being returned to someone else.
- theshrike79 3y agoAs long as you can get the battery working, even with the missing cells, it's gonna be multiple tens of kilowatts of capacity. And if you can sell the client a full battery replacement for full price while still keeping the old one, you're making $$$
