INSPECTION DEVICE FOR BATTERY VOLTAGE LOWERING

摘要

PROBLEM TO BE SOLVED: To provide an inspection device for battery voltage lowering capable of accurately performing periodical inspection of battery voltage lowering based on the comparison results of the detected voltage corresponding to the terminal voltage of the battery with the detected voltage. SOLUTION: The device periodically inspecting voltage lowering of a battery 3 based on the comparison result of a reference voltage of a preset detection voltage with the detected voltage corresponding to the terminal voltage of the battery 3 obtained by supplying power from the battery 3 to the load R1 for inspection on the drive circuit 7 by closing a switch SW1 on the drive circuit 7 and sending current to the drive circuit 7 comprises a switch closing means 1a for closing the switch SW1 at every constant period. Current sending for disassembling a protection film generating on the surface of battery 3 terminal during opening of switch SW1 is conducted on the drive circuit 7 while closing the switch SW1 by a switch closing means 1A.
