Problems solved by technology

In particular, when a module is to be replaced by a module of a new design, if the battery module of the new design is not compatible with the previous battery module or the battery system, in other words it will lead to disturbances in the operation of the battery
However, the use of other types of battery modules is necessary if, for example, the previously used design is no longer available or if battery modules with improved battery technology are to be used

Abstract

A battery management system (1), a battery module (30), a battery system (50) and a motor vehicle are described. In order to be able to replace the battery module (30) safely, a battery module (30) with a data memory (39) and a control unit (2) and a bridge switch (3, 4) The battery management system (1), wherein the control unit (2) closes the bridge switches (3, 4) and thus bridges the battery modules (30) by means of data from the data memory (39).

Description

technical field [0001] The invention relates to a battery management system for a battery having at least one battery module, wherein the battery management system has at least one bridging switch for bridging the at least one battery module and a control device for controlling the bridging switch . Furthermore, the invention relates to a battery module for a battery having at least one battery cell. Furthermore, the invention relates to a battery system with a battery comprising at least one battery module and a battery management system with a bridging switch for bridging the battery modules as required. Finally, the invention relates to a motor vehicle with a battery system, wherein the battery system is connected to a drive system of the motor vehicle. Background technique [0002] Battery management systems and battery modules of the kind mentioned, as well as battery systems and motor vehicles are generally known. For example, a battery management system is used to ...
