ABSTRACT:
A battery pack has a rechargeable battery, a pair of externally exposed charge/discharge terminals connected to the electrodes of the rechargeable battery, and an externally exposed battery pack signal terminal for identifying the type of the battery pack. The battery pack further has a battery pack communication portion connected to the battery pack signal terminal for receiving an authenticity signal transmitted from an electrical equipment unit through the battery pack signal terminal; a random number generating portion for generating a random number based on a predetermined condition; and a battery pack control portion for generating a detection signal based on the authenticity signal received by the battery pack communication portion and the random number generated by the random number generating portion, and for transmitting the detection signal from the battery pack communication portion to the electrical equipment unit side through the battery pack signal terminal.
