Abstract: An auxiliary power supply system includes a plurality of electrical storage devices that supply power to an electrical device. Each of the storage devices has the communication capability with the electrical device. Each of the storage devices provisionally selects one of a plurality of first communication addresses as a provisional communication address of its own. The plurality of first communication addresses have been set for the plurality of electrical storage devices by the electrical device. Each of the storage devices returns a response signal in reply to a transmission signal, to which the provisional communication address of its own is added. Each of the storage devices changes, when finding that any communication error has occurred while returning the response signal, the provisional communication address of its own into one of one or more unused communication addresses belonging to the plurality of first communication addresses that have been set.
