Battery pack provided with authentication circuitry
First Claim
1. A battery pack provided with authentication circuitry, the battery pack comprising:
- a rechargeable battery;
output terminals connected to the rechargeable battery directly or via a switching device; and
an authenticity discriminating circuit to output a battery pack authenticity discriminating signal to an electrical equipment to which the battery pack is attached;
wherein the rechargeable battery does not supply electric power to the authenticity discriminating circuit;
wherein the authenticity discriminating circuit comprises a receiver section to receive an activating radio wave sent from the electrical equipment to which the battery pack is attached, a transmitter section to send an authentication radio wave as the authenticity discriminating signal when the receiver section receives an activating radio wave, and a power supply section to convert the activating radio wave sent from the attached electrical equipment into direct current electrical power to supply to the receiver section and the transmitter section; and
wherein the authenticity discriminating circuit supplies power to the receiver section and the transmitter section by the power supply section when the battery pack is attached to the electrical equipment and the electrical equipment sends an activating radio wave to the power supply section, and the transmitter section sends an authentication radio wave to discriminate battery pack authenticity.

Abstract
The battery pack is provided with output terminals and an authenticity discriminating circuit. The authenticity discriminating circuit is not supplied power from the rechargeable battery, nor is it connected to either the rechargeable battery or the output terminals. The authenticity discriminating circuit is provided with a receiver section which receives an activating radio wave from the electrical equipment, a transmitter section which sends an authentication radio wave as a signal to discriminate authenticity when the receiver section receives the activating radio wave, and a power supply section which converts the activating radio wave to direct current to supply electrical power to the receiver section and the transmitter section. When the battery pack is attached to electrical equipment and the authenticity discriminating circuit receives an activating radio wave, the power supply section supplies power to the receiver section and transmitter section, and the transmitter section sends an authentication radio wave to discriminate battery pack authenticity.
