    • This invention includes a method for charging lithium-based batteries. Battery type is identified by a charger by way of a third terminal. For nickel-based cells, the third terminal is coupled to a thermistor for sensing temperature. For lithium-based cells, the third terminal is coupled to the rechargeable cell disposed within the battery pack. If a nickel cell is identified, the cell is charged by conventional means. If a lithium cell is identified, the charger applies a full current until any serial elements disposed between the battery pack terminals and the cell reach a high impedance state. The charger then reduces the charging current to a low level for a predetermined time. After this time has elapsed, the charger then reapplies a high current. If the voltage across the serial elements remains low, charging continues. However, if the voltage across the serial elements exceeds a predetermined threshold, the charger then decrements the current by a predetermined amount.
    • 本发明包括一种锂基电池的充电方法。 电池类型由充电器通过第三个端子识别。 对于镍基电池,第三端子耦合到用于感测温度的热敏电阻。 对于锂基电池,第三端子耦合到设置在电池组内的可充电电池。 如果镍电池被识别,则电池通过常规方式充电。 如果识别出锂电池,则充电器施加全电流,直到设置在电池组端子和电池之间的任何串联元件达到高阻抗状态。 然后,充电器将充电电流降低到低电平达预定时间。 在这段时间过去之后,充电器然后重新应用高电流。 如果串行元件上的电压保持不变,则继续充电。 然而,如果串联元件两端的电压超过预定阈值,则充电器将电流减小预定量。
