Embodiment Construction

[0026] exist figure 1A monitoring circuit 30 according to the invention for a battery module is shown in . The monitoring circuit 30 has two connections 11 , 12 via which the monitoring circuit is connected to the bus lines of the bus system. Typically, such a bus system can be implemented as a CAN bus. Typically, then, the connection 11 is connectable to the first bus conductor of the CAN-bus system, which is referred to here as the CAN high line, and the connection 12 is connectable to the second bus conductor of the CAN-bus system. connected, which is referred to herein as the CAN low line. The monitoring circuit 30 also has a transceiver circuit 20 which is connected to the first and the second connection of the connections 11 , 12 and is designed to react to the reception of a signal in logic with a signal at the connection The corresponding potential changes at 11, 12. When the monitoring circuit 30 is connected to two bus lines, for example to the two bus lines of a...
