    • A charger for portable terminal equipment, capable of distinguishing a nickel-hydride battery pack and a nickel-cadmium battery pack and of detecting an on-hook/off-hook condition even when the nickel-hydride battery pack is used. The charger includes a charging circuit, a pair of third charging terminals connected to the charging circuit and adapted to be selectively connected to either a pair of first charging terminals of the nickel-hydride battery pack or a pair of second charging terminals of the nickel-cadmium battery pack, and a third auxiliary terminal adapted to be selectively connected to either a first auxiliary terminal of the nickel-hydride battery pack or a second auxiliary terminal of the nickel-cadmium battery pack. The charger further includes a device for comparing a voltage at the third auxiliary terminal with a first reference voltage and detecting the on-hook condition or the off-hook condition of the portable terminal equipment, and a device for comparing the voltage at the third auxiliary terminal with a second reference voltage lower than the first reference voltage and distinguishing the nickel-hydride battery pack and the nickel-cadmium battery pack.
    • 一种用于便携式终端设备的充电器,其能够区分镍氢电池组和镍镉电池组,并且即使在使用镍氢电池组时也检测挂机/摘机状态。 充电器包括充电电路,连接到充电电路的一对第三充电端子,并且适于选择性地连接到镍氢电池组的一对第一充电端子或镍 - 氢电池组的一对第二充电端子, 镉电池组和第三辅助端子,其适于选择性地连接到镍氢电池组的第一辅助端子或镍镉电池组的第二辅助端子。 充电器还包括用于将第三辅助端子处的电压与第一参考电压进行比较并检测便携式终端设备的挂机状态或摘机状态的装置,以及用于比较第三辅助端子处的电压的装置 端子,具有低于第一参考电压的第二参考电压,并区分镍氢电池组和镍镉电池组。
