A battery ECU provides an N-th arithmetic processing device with an ID assignment signal. The N-th arithmetic processing device receives the ID assignment signal, and stores an ID that is transmitted by the battery ECU. The battery ECU provides an i-th arithmetic processing device (i is a natural number from N to 2) with a command for providing an ID assignment signal. The i-th arithmetic processing device provides the (i-1)-th arithmetic processing device with the ID assignment signal in response to the command for providing an ID assignment signal. The (i-1)-th arithmetic processing device receives the ID assignment signal, and stores an ID that is transmitted by the battery ECU.
