Abstract
A battery management system includes monitoring devices arranged in a housing accommodating a battery. The monitoring devices monitor the battery and acquire battery monitoring information. The controller performs wireless communication with each of the monitoring devices via a wireless communication connection. The controller transmits a disconnection instruction to each of the monitoring devices. Each of the monitoring devices periodically executes a requesting operation after disconnection of the wireless communication connection. The controller accepts the requesting operation to establish the wireless communication connection. The controller and each of the monitoring devices perform a periodic communication of the battery monitoring information via the established wireless communication connection. Each of the monitoring devices determines start timing of the requesting operation based on reception timing of the disconnection instruction so that at least some of timings of requesting operations of the monitoring devices do not overlap with each other.
