Why don't electric cars have batteries that are swapped, rather than recharged in the vehicle?
OK instead of having monolithic battery blocks, use modular "cubes" of say 2ft wide. change them from under the vehicle and hang them underneath the car. Plates, to keep them in will form a cover for the battery compartments. Few people look at the undersides of cars so it shouldn't spoil the lines. If dimensions chosen carefully then it SHOULD be possible to fit them in a wide range of vehicles. pick up trucks can of course have more.
Weight to lift. something like a lifting pallet truck+ some air tools to undo bolts.
Quantity required. Why would so many be needed? Only need sufficient batteries to deal with 1 full days resupply. Thought electric cars did about 800 miles. if average use is 80 miles a day, that would work out at average of 1 complete battery recharge every 8 days. 1/8 th of the total number of batteries installed in vehicles should cover that.
New battery technology does cause changes to the voltage of an individual cell. But as batter
