Abstract (en)
[origin: WO2020260244A1] The invention relates to a method for charging a high-voltage battery (3) of an electric drive (14) of a vehicle (1), in which electrical power is transmitted from a low-voltage on-board electrical system (4) of the vehicle (1) to the high-voltage battery (3), and, to aid starting of the vehicle (1), electrical power is transmitted from a separate external unit (9) to the low-voltage on-board electrical system (4) of the vehicle (1) and is transmitted from the low-voltage on-board electrical system (4) to the high-voltage battery (3). The invention also relates to a power transmission system (8).
