Reply to comment by hacktheself in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
I would need to visit a special place to recharge my car and a person or myself would have to manually remove 1000lbs of battery and replace it with a new one? That sounds like a much, much worse option than just taking 3 seconds to plug it into the charger in my garage. I don’t see how that’s better for anyone, even if you can’t charge at home and need to visit DC fast chargers all the time.
Could I do it both ways? Allow swapping and charging at home? Sure, but is that worth the immense design and engineering trade offs, when home charging + DC fast chargers work fine in almost all cases?
Relying on swapping would also be a big profit center for car companies because they could charge big recurring swap subscriptions. They don’t do it because it’s a bad idea, not just because of money.
