If batteries are easily swappable with minimal tools, then a lot of range concerns go away as well. I think battery ownership and care needs to be decoupled from the vehicle. I also think the federal government should enforce interoperable batteries between vehicle brands.
The cars shape and structural components are designed around the battery. The cars software, motors, charging electronics, software, cooling systems, etc are all designed for the specific battery. The battery eats up a significant fraction of the cost of the car, and the systems designed around it a significant fraction of the remainder. Asking for interoperable batteries between vehicle brands is like asking for int…
But it seems like there could be a hot-swappable portion of the battery, kind of like a separate "reserve tank" (although it wouldn't actually be reserved).
Some back of the envelope math says that if 1200 lb battery gets you 250 miles, a 200 lb hot-swap battery would get you 40 miles. Possibly enough to get to your next destination.
