  • Patent number: 9739836
    Abstract: The disclosure describes a battery management system, a battery module, a battery system and a motor vehicle. In order to be able to reliably exchange battery modules, the battery module is provided with a data memory, and the battery management system is provided with a control apparatus, which can be connected to the data memory so as to transmit data, and with a bridging switch, wherein the control apparatus closes the bridging switch on the basis of the data in the data memory and therefore bridges the battery module.
