BATTERY POWER SUPPLY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a battery power supply device in which damage of equipment and occurrence of faults of a battery are avoided in the case they are brought about owing to fluctuation of battery performance by connecting a plurality of batteries in series, or in the case a part or all of the batteries are installed by mistake with an inverse positive electrode and the negative electrode or the like. SOLUTION: The battery power supply device uses diodes in which the maximum rated current in forward direction of the diodes is larger than the current which the battery supplies by the potential difference in forward direction of the diodes.
