Abstract: A system for optimally recharging a battery cell while powering a device connected to the battery pack, in which an electronic switch (22) connects a battery pack power-output either to the battery cells (12) or to a second power-input contact (20). When not recharging, the battery-pack power-output contact (16) is connected to the battery cells (12), thereby powering the device from the cells. When recharging via a charging unit, the battery pack's power-output terminal is uncoupled from the cells (12) and coupled to a power source of the charging unit, thereby powering the device from the charging unit. At the same time, a voltage is supplied to the battery cells (12), thereby recharging them. The switching may be activated by a voltage supplied by the charging unit to a temperature monitoring thermistor (24) in the battery pack. In this way, the battery pack's power output may be automatically switched whenever it is placed in the charging unit.

Abstract translation: 一种用于在连接到电池组的设备供电的同时对电池单元进行最佳充电的系统，其中电子开关（22）将电池组功率输出连接到电池单元（12）或连接到第二电力输入触点（ 20）。 当不再充电时，电池组功率输出触点（16）连接到电池单元（12），从而从电池为设备供电。 当通过充电单元再充电时，电池组的电力输出端子与电池单元（12）分离并耦合到充电单元的电源，从而从充电单元向设备供电。 同时，向电池单元（12）供给电压，从而对它们进行再充电。 可以通过由充电单元向电池组中的温度监视热敏电阻（24）提供的电压来激活开关。 这样，每当放置在充电单元中时，电池组的电源输出就可以自动切换。
