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. ■...
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.
