Standardize Electric Car Batteries so that Drivers can quickly exchange Battery Units at Charging Stations rather than charge a Car's Own Batteries

Are we missing something?

The main problem with electric cars is the rather ridiculous state of affairs that each car has its "own" set of batteries which have to be recharged at charging stations over a considerable period of time, which greatly limits the mobility of electric cars - and greatly impedes their sale.

The solution is simple. Perhaps others have already suggested this solution, but in this case, this is our idea.

There is no reason for drivers to have to recharge "their" batteries. Rather, what needs to be done is to standardize electric car batteries so that the entire battery unit can simply be replaced at charging stations in a matter of minutes, just like filling the gas tank. When car buyers see that electric cars then have practically no mileage limitations, sales of electric cars will skyrocket.
