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.
