I am also not a fan of the leasing concept.No.
I still hate the leasing concept. After the useful life of the battery for automotive purposes has ended it still has value. It could be integrated into the renewable energy system of my house, for instance. Or perhaps sold on to another end user of some type.
I don't know. Leasing always struck me as a way for a manufacturer to get more money for a product than it could by selling it outright.
I suspect that, once the BEV's battery has reached the end of it's useful life, it would not be particularly useful in a home energy system. You might use it to hold down a large tarp or something, though. . . I think I'd just rather recycle it.
