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.

Description

technical field [0001] The present invention relates to a battery pack with a circuit for distinguishing authenticity from genuine products and model products. Background technique [0002] A battery pack is detachably mounted on an electrical device to supply power to the device or mounted on a charger to be charged. This battery pack is manufactured in various rated types according to the driving voltage or driving current of the installed device. Since such battery packs have different output voltages or capacities, when charging, different charging voltages or charging times are set according to different battery packs. Therefore, various chargers suitable for battery packs have been developed. When installing a battery pack that does not meet the rated value of the electrical equipment or charger, it may cause incorrect operation of the electrical equipment or charging errors such as overcharging or undercharging. It is also related to the failure of electrical equip...
