Kind Code:
A1
Abstract:
This battery control device comprises: a leader device that monitors the state of a plurality of battery cell groups provided in a vehicle; and a plurality of follower devices that are installed in the respective battery cell groups, that detect the state of each of the battery cell groups, and that transmit the states of the battery cell groups to the leader device. The leader device and the plurality of follower devices communicate in turns through time-sharing. The follower devices each have an anomaly detection unit that monitors communications between other follower devices and the leader device to detect anomalies in the communications, and if the anomaly detection unit detects an anomaly in the communication, the host follower device transmits the information of the other follower device together with the information of the host follower device to the leader device.
