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

A method for load management of a charging station, in which the charging station is formed by at least two charging points, each with a charging control and a power electronics module assigned to the respective charging point, a charge management server and a transformer connected to an electricity supply network. The network provides a transformer power, in which the load management carried out by the load management server controls an allocation of the transformer power among the respective charging points, in which a respective charging operation of a particular electric vehicle at a particular charging point is controlled via the respective charging control connected to the load management. Charging power controlled by the load management is provided by the respective power electronics module assigned to the respective charging point. The load management has a dynamic and a static execution mode.

A method and system for identifying a vehicle type of a vehicle having an electric drive and a traction battery, in which a charging behavior of the vehicle that occurs during a current operation of charging the traction battery at a charging column is captured. A current charging profile is created for the current charging operation on the basis of the captured charging behavior. The current charging profile is compared with respective charging profiles which are retrievably stored in a storage unit and are each specific to a respective particular vehicle type. A probability of a presence of a particular vehicle type from the plurality of vehicle types is determined on the basis of the comparison. The vehicle type most likely to be present is identified as the vehicle type and the current charging operation is adapted to the vehicle type which is most likely to be present.
