摘要:
The signal output circuit of the highest rank state detection section outputs an abnormal signal that is generated by the processing device when an abnormality is detected by the abnormality detection section. When no abnormality is detected, a normal signal is generated by the processing device and output as the detection signal. In each state detection section other than that of the highest rank, the signal output circuit outputs an abnormal signal generated by the processing device when an abnormality is detected by the abnormality detection section, and outputs the detection signal input from a higher rank state detection section when no abnormality is detected.

摘要:
One state detector detects an abnormal state or a normal state relating to charge and discharge of a battery cell group in one battery module, and generates one detection signal representing the detected state. Another state detector detects an abnormal state or a normal state relating to charge and discharge of another battery cell group in another battery module, and generates another detection signal representing the detected state. One operation processing device sends the one detection signal generated by the one state detector to an external object. Another operation processing device sends the other detection signal generated by the other state detector to the external object. The one detection signal generated by the one state detector is transmitted to at least one of the other operation processing device and the other state detector via a signal line.

A battery module includes a plurality of battery cells, a detection circuit, a communication unit, and a printed circuit board. The detection circuit and the communication circuit are mounted on the common printed circuit board. The detection circuit detects a voltage of each of the battery cells in the battery module, and feeds the detected voltage to the communication circuit. The communication circuit is connected to a communication circuit in another battery module or a battery ECU. Thus, the communication circuit in the battery module and the communication circuit in the other battery module or the battery ECU can communicate with each other.
