  • Method for charging a traction battery of an electric vehicle by means of a charging column and charging system
    Patent number: 12145462
    Abstract: A method for charging a traction battery (1) of an electric vehicle b a charging column (2) is provided. The traction battery (1) can be charged at two or more different charging voltage levels. After the electric vehicle has been connected to the charging column (2), data is exchanged between a battery management system (3) of the electric vehicle and the charging column (2) to negotiate a charging voltage. For this purpose, a maximum permissible total charging voltage is communicated to the charging station (2) by the battery management system (3) via a battery handshake message (BHM) (4). The communicated maximum permissible total charging voltage is lower than a highest charging voltage level of the traction battery (1) by a defined measure.
