Nio is a Chinese auto maker that offers an alternative to charging: just swapping out the whole battery whenever you need it. I borrowed one of their cars. ■...
Can’t tell if this is a serious comment or not… Sure a battery will last as long as the car, but it’s of limited use of it only holds 30% of its original capacity after 7 or 8 years. Sure. It’ll do 75 miles, so still useful for city drivers, but not for its intended use.
You have that backwards. The vehicle is good for the life of the battery. We could design EV where the shell and motor last 30 years, and the battery just swaps out every decade or so.
I don’t think so. Think of the engineering challenges. The battery would have to be a separate structure so more weight, less range/performance, more wear on tires and brakes, less rigidity unless you add even more weight, etc.
Batteries can be replaced now. It’s just a time consuming job but one that might only need doing once.
Aren’t EV batteries good for the life of the vehicle? Why would you want to replace one?

EV batteries lose about 1-2‰ per year. At the high end, that would be down to 78% after 10 years. A 300mi EV would still do 230mi.

Cars need to repairable. Plus lithium fails quite a bit.
If a car can work 10+ years thats a good thing. And most lithium based batteries will not last that long.
I don’t think that’s a fair statement in relation to EV batteries. Most of them are proving to last well over 10 years.
