1. A battery management system comprising:
at least one monitoring device configured to monitor a 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 controller is configured to transmit a request for battery monitoring information to the at least one monitoring device,
the at least one monitoring device is configured to transmit the battery monitoring information to the controller in response to the request, and
the controller is configured to determine whether missing of the battery monitoring information has occurred based on a correlation between the battery monitoring information acquired from the at least one monitoring device via wireless communication and relationship information held by the controller related to the battery monitoring information,
the controller is configured to:
acquire the battery monitoring information from the at least one monitoring device via wireless communication;
acquire wired information which is information indicating the state of the battery via wired communication without the at least one monitoring device; and
execute the predetermined process based on the acquired battery monitoring information and the wired information,
the relationship information is the wired information,
the controller determines that the missing of the battery monitoring information has occurred when the battery monitoring information corresponding to the wired information cannot be acquired.
