How does AC charging work and what are the advantages?
AC charging stations supply the electric car with alternating current (AC). An on-board charger in the vehicle converts the alternating current into the direct current (DC) required for the battery.
The charging capacity of most on-board chargers is between 3.7 and 22 kW. Theoretically, up to 44 kW are possible.
The charging power depends, among other things, on the vehicle model, the available power supply, the cabling and the construction of the charging point.
AC charging is particularly useful for longer idle times of 20 minutes or more: at home overnight, during working hours, when doing weekly shopping, etc.
AC charging is very beneficial to the grid, as users expect a certain length of stay, anyways, which gives more leeway to control the charging capacity.
