Charging cars at home at night is not the way to go: study
I need ELI5:<p>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 &quot;battery station&quot;, where you would park at a spot&#x2F;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?<p>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&#x27;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).<p>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.<p>I just don&#x27;t get it. Governments around the world and spending trillions on this stuff so why is there no clear answer on this?
