[0032]FIG. 1 shows a schematic diagram of an electric or hybrid vehicle with a charging device 12 according to the prior art.
[0033] The AC current input terminal 12.1 of the charging device 12 is connected to an AC power source, such as a power grid, through an AC cable 11 with an In-Cable Control and Protechnological Device (IC-CPD). The charging device includes a rectifier (AC / DC converter). The DC current output 12 . 2 of the charging device 12 is connected via a DC cable 13 to a charging socket 14 (CCS) of the vehicle. The direct current is transmitted to the high-voltage battery 15 of the vehicle via a switching unit 16 ("Battery Junction Box", BJB) of the battery management system. The charging process is regulated by the vehicle's control device 17 (Electronic Control Unit, ECU). The power components of the charging device 12 that perform the voltage conversion (AC / DC) are therefore located outside the vehicle.
