A battery monitoring system according to an embodiment includes a plurality of battery monitoring apparatuses provided in accordance with battery packs. Each of the battery monitoring apparatuses includes a setting unit and a communication unit. The setting unit sets a communication system to at least one of a first communication system and a second communication system having a shorter communication period than that of the first communication system, sets the communication system to the second communication system during a failure diagnosis to be performed in a start-up of the corresponding battery monitoring apparatus, and sets the communication system to the first communication system after the failure diagnosis. The communication unit communicates with another battery monitoring apparatus of the plurality of battery monitoring apparatuses by using the communication system set by the setting unit.
