In AC charging, the rectifier built inside the car, is called ‘’on board charger’’ and converts power from AC to DC. After this conversion the car’s battery is fed by DC current.
Most charging stations that you can find today, use AC charging. The usual charging speed is 22kW, depending on the car you have (most cars have 11kW on board charger), as well as the available power of the charging infrastructure. It is ideal for charging your car at home or at work, as the time required to charge it is quite long.
