Monitoring of vehicular batteries is realized with a configuration in which the number of wires can be reduced and information can be better transmitted. A battery monitoring device includes: a detection unit configured to detect at least one of a voltage at a predetermined position of a battery installed in a vehicle and a temperature of the battery; and a wireless communication unit configured to wirelessly transmit detection information that indicates at least one of the voltage and the temperature of the battery based on a detection result of the detection unit, the detection information being wirelessly transmitted at least to a relay that has a function to relay and wirelessly transmit information to a battery ECU.
