Abstract: A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery. The monitoring device monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and executes a predetermined process based on the battery monitoring information. The monitoring device holds imperfect information that is battery monitoring information indicating failure of data transmission/reception between the monitoring device and the controller. The monitoring device retransmits information corresponding to the imperfect information from next time the battery monitoring information is transmitted.
