Not sure it’s practical to hot swap EV batteries right now.
“An electric vehicle battery typically weighs between 300 kg (660 pounds) and 900 kg (2,000 pounds).”

Getting automakers to agree to a standardized form factor (and to not put non-battery components in their battery packs ala Tesla,) automatically locating and removing whatever retentioning mechanism is used, having a large enough stock of batteries at each “filling station”, etc. are more difficult problems.
But, as I said, I hope this does happen in the future.
But it begs a question, who’s liable when the battery is swapped to some faulty unit that catches fire when it’s in your car?
(I’d expect that all-in, this gets a lot closer to the cost of a gasoline fill-up. My current charging costs are far lower than the equivalent cost to fill up with gasoline, but my primary interest in this is environmental. I’ll take the lower cost while I can get it, but I don’t expect it to last forever.)
Of course, here in the US we don't need any of that commonist technology. We're all so great, we're gonna say "Please, Please, don't make me any greater!". Can't wait 8-/
So, qualify what I wrote before with: _in_China_ they'll be able to charge as fast as a refuel.
