Okay, sure, in Canada, where the number of EVs is already low and access to used parts is almost nonexistent, someone scrapped a single copy of an extremely unpopular toy EV with a tiny battery that sold only 22,000 units in total that model year worldwide.
That's not an EV problem. It's an ultra-rare car problem. Rare ICE cars have the same problem.
FWIW, when you can actually get them, used batteries for that model of car cost only about $4k. But you'll probably spend another $2,000 on shipping it by boat from Europe, because there are more people living in my immediate neighborhood plus the one across the street than there are 2017 Ioniq EVs in all of North America.
So let me restate that. There are no *popular* EVs that are getting scrapped because of the cost of battery replacement. After all, you could make that battery from scratch today for about $3,000, give or take, if somebody actually cared to do so. But they don't, because there's no market for it. You could also replace all the cells in that battery for under $3k, not including the labor. So a $50k estimate falls into "don't make me laugh" territory. It's a ludicrously inflated price, probably because they don't actually have any of the batteries left, and would have to spin up a production line just to build more. :-D
