PURPOSE: To provide a monitor device for a battery set in which wiring can be simplified and the operation of wiring can be quickly and accurately performed by providing a voltage measuring unit closely to the respective corresponding module batteries. CONSTITUTION: The input terminals of each voltage measuring unit 201∼224 are connected to the plus and minus terminals of both ends of the respective corresponding batteries 101∼124. ECU 3 transmits and receives a signal from each voltage measuring unit 201∼224 through a communication antenna 4b, a transmission circuit 25 and a modulation/demodulation circuit 26. Accordingly, it is unnecessary to connect each voltage measuring unit to the ECU 3 by using a lead wire. Thus, each voltage measuring unit provided in the module battery is simply connected between both end terminals of each module battery, and at that time, wiring is clear and easy. Accordingly, the operation of wiring is speeded up and the erroneous connection at the time of wiring hardly occurs. |
