Embodiment Construction
[0029] figure 1 A very simplified schematic diagram of a battery management system 1 for monitoring and regulating the operation of a rechargeable battery with a plurality of battery modules 3 electrically connected to one another, each comprising at least one battery cell 2 , is shown. The battery management system 1 includes a controller unit 4 and a plurality of cell monitoring units 5 . Furthermore, the battery management system 1 includes a further functional unit 6 which is designed here to control and / or regulate the temperature of the battery modules 3 . These battery cells 2 have corresponding sensors ( figure 1 not explicitly shown). The measured values recorded by the sensors are transmitted to the cell monitoring units 5 via signal transmission lines 7 . These cell monitoring units 5 in particular take on the task of so-called cell monitoring circuits (CSC). These cell monitoring units 5 are designed in particular to carry out so-called cell balancing. The c...
