electric cars have very large and heavy batteries right? Why is it prohibitively difficult to replace them on demand? What if there were 2-3 batteries charging at home or hundreds at a "battery station", where you would park at a spot/drive-thru garage and have a hydraulic machine drop your old battery and lift in a new battery and the whole swap can take no longer than the time it takes to fill up a has car and you have less queues. Why is this not possible?
If it takes an hour to charge a battery and a battery station has 200 charging at any given time, and it takes 2 minutes to swap a battery then 6 charging bays can replace batteries for 180 cars leaving 20 extra batteries for defects and other issues. Couldn't such a charging station be implemented on a similar lot and budget of constructing a medium size gas station (at least a dozen pumps and around 1 acre lot).
A charging station that is twice as efficient with a 30min charge time can do 2 cars at most in one hour. You need 90 charging station to reach that efficiency even without considering the queues.
I just don't get it. Governments around the world and spending trillions on this stuff so why is there no clear answer on this?
