A motor vehicle traction battery arrangement includes two cooling plates respectively disposed in a horizontal plane and a high-voltage battery module. The lower and upper horizontal walls of which are cooled directly by the cooling plates and which encases a plurality of identical rectangular battery cells in a rigid battery module housing. The battery cells are all configured such that they are plate-like and elongated, are parallel to one another in vertical planes (y,z) and each includes two small-area vertical end walls, two large-area vertical side walls and two medium-area horizontal walls. On its end face, each battery cell includes an anodic connecting element and a cathodic connecting element. At least two similar cell stacks including a same plurality of battery cells are provided, and are stacked such that their battery cell side walls adjoin one another. The battery cell horizontal walls directly adjoin a cooled battery module horizontal wall.

Traction battery of a motor vehicle

A safety apparatus () for a battery () has a base () for a vehicle (), sensors () and an evaluation apparatus (). Each sensor () is designed to generate a sensor signal () on a basis of a deformation of the base () and to supply the sensor signal to the evaluation apparatus (). The evaluation apparatus () ascertains from the sensor signals () both first information about the location of the deformation of the base () and second information about the level of the deformation, and uses the first information and the second information as a basis for determining whether a first state (Z) is present, in which a driving mode can be maintained, or whether a second state (Z) is present, in which a driving mode can no longer be maintained.

Safety apparatus for a battery

A method for autonomously interconnecting at least two battery banks in a drive system of a motor vehicle, the drive system comprising at least one electric motor, at least two battery banks, at least one traction system which can be supplied with power by at least one battery bank, and at least one DC/DC converter which can be connected to at least one battery bank. The battery banks can be interconnected with one another in series and/or in parallel and at least one battery bank can be bridged, wherein, during autonomous operation of the motor vehicle, respective interconnection of the at least two battery banks is automatically carried out within the drive system, depending on a respective operating state of the motor vehicle.

Autonomous interconnection of a drive battery
