OVERVOLTAGE DETECTING DEVICE FOR ENERGY STORAGE MODULE

Provided is an overvoltage detecting device for an energy storage module, including a plurality of overvoltage detecting sections, each of which is connected in parallel to each of a plurality of storage cells, is supplied with power from an external power supply, and monitors an interterminal voltage of the each of the plurality of storage cells. The plurality of overvoltage detecting sections output an ON signal for indicating that the storage cells are normal when the interterminal voltages of the plurality of storage cells are a predetermined reference voltage or lower. The plurality of overvoltage detecting sections output an OFF signal when the interterminal voltages of the plurality of storage cells exceed the reference voltage.
