All EVs take quite a while to charge, usually 24 hrs. if all you use is a 120 volt outlet.
Bingo! if you use a 120 volt outlet from normal house current with normal household current that is 15 amps per circuit.
The chargers are built into EV's. Charging stations only provide the power required to run the internal charger.
There is an onboard computer that can see how much power is available and adjusts the onboard charger accordingly.
That means two EVs plugged into the same charging station can take different amounts of time to charge based on battery size, battery charge level, and the capabilities of the chargers built into each vehicle.
Different electric vehicles have varying battery capacities. The battery's capacity is similar to the size of a fuel tank in a gas-powered vehicle, and it has a direct impact on the range of the vehicle. Big batteries provide more range, but they also take longer to charge when fully drained, just like a big fuel tank takes longer to fill than a small one.
The charging stations along the interstates provide up to 50 amps of power which drastically decreases the time required to recharge and get back on the road.
IMHO EV's are probably going to work ok for a commuter vehicle of short distances but driving cross country is going to difficult just like the Natural Gas vehicles that quickly faded away because there were few places to refuel.
There are people driving them across the country but they spend a lot of time in restaurants at charging stations.
Battery technology still isn't where it needs to be to make EV's a long range driver.
