1. A battery management system comprising:
at least one monitoring device arranged in a housing accommodating a battery and configured to monitor the battery and acquire battery monitoring information that includes information indicating a state of the battery; and
a controller configured to perform wireless communication with the at least one monitoring device and execute a predetermined process based on the battery monitoring information, wherein
the battery monitoring information includes multiple pieces of data including a cell voltage that is a voltage of a battery cell constituting the battery, and a cell temperature that is a temperature of the battery cell,
the at least one monitoring device is configured to insert the battery monitoring information in a packet and transmit the packet to the controller during a period of a connection process executed for establishing the wireless communication between the at least one monitoring device and the controller, and
the at least one monitoring device is configured to prioritize transmitting the cell voltage over other data among the multiple pieces of data to the controller during a period of the connection process executed when the at least one monitoring device and the controller are activated by supply of an activation signal.
