A method for discharging a battery module, having at least two battery cells, of a battery having at least two battery modules, wherein the battery cells of each of the battery modules are arranged next to one another and are mechanically and electrically connected to one another, wherein, in each of the battery modules, the respective battery cells are individually activated and deactivated in terms of an energy storage function by a cell switch unit, wherein the battery cells of the battery module to be discharged are selectively electrically coupled successively to a discharge device by the cell switch unit and starting from one predefined battery cell, in order to individually successively electrically discharge the battery cells in order to discharge the battery module.

Discharging a battery module, having at least two battery cells, of a battery having at least two battery modules

The invention relates to a battery () having a plurality of battery cells () which form a cell stack () which stands on a bottom plate () of the battery (). At least one wedge () is provided to brace the battery cells () against one another. The at least one wedge () and the cell stack () are secured in their position relative to the bottom plate () by at least one bracket () which is mounted to the bottom plate (). Manufacturing tolerances of the battery cells () can be compensated by the at least one wedge (), and the bracket () secures both the wedge () and the cell stack ().

Battery having a plurality of battery cells

The invention relates to a HV-battery, in particular a traction battery for a vehicle, having a plurality of cell modules which each comprise a plurality of cells, wherein each cell module is assigned a controller for cell monitoring and/or for cell balancing, wherein the controllers are connected to a battery management control device for communication or open-loop control and/or closed loop control purposes, wherein the HV-battery is of modular construction by configuring the cell modules as plug-in modules that are detachably mountable or can be mounted to a printed circuit board.

HV-battery, in particular traction battery for a vehicle

The invention relates to a communication system for a motor vehicle for transmitting an information relating to the operation of the motor vehicle from a transmitting control device to a receiving control device. The communication system comprises an interface for the input or output of the information relating to the operation of the motor vehicle. Communication can be established via the interface by means of a protocol which comprises an operation field for identifying a task to be carried out using the information relating to the operation of the motor vehicle.

Communication system for a motor vehicle

A control system for a motor vehicle comprises an output control unit for outputting data related to the operation of the motor vehicle and an operation control unit spatially separated from the output control unit for generating or providing data related to the operation of the motor vehicle. The output control unit comprises a data storage for storing data related to the operation of the motor vehicle and the data related to the operation of the motor vehicle can be read out of the data storage and outputted by the output control unit.
