Abstract: A battery pack (10) is connected to a load or charger (12) and includes battery cells (20), under-voltage switch (22), a first voltage controlled switch (24), over-voltage switch (28), and second voltage controlled switch (30). Under-voltage switch (22) can block only discharge current, any recharge current may pass through it regardless of its switch state. Over-voltage switch (28) can block only recharge current when switched off and will always allow discharge current to flow regardless of its switch state. First voltage controlled switch (24) maintains under-voltage switch (22) on while battery voltage V1 is above a predetermined under-voltage level. When V1 drops to, or below, the under-voltage level first voltage controlled switch (24) switches off under-voltage switch (22) with a switch signal on line (26). Second voltage controlled switch (30) maintains over-voltage switch (28) on while battery voltage V1 is below a predetermined over-voltage level. When V1 reaches or exceeds the over-voltage level second voltage controlled switch turns off over-voltage switch (28) via a switch signal on line (34).

Abstract translation: 电池组（10）连接到负载或充电器（12），并且包括电池单元（20），欠压开关（22），第一电压控制开关（24），过电压开关（28）和 第二电压控制开关（30）。 欠压开关（22）只能阻止放电电流，任何充电电流都可以通过它，无论其开关状态如何。 过电压开关（28）只能在关断时阻止充电电流，并且始终允许放电电流流过，无论其开关状态如何。 当电池电压V1高于预定的欠电压电平时，第一电压控制开关（24）保持欠电压开关（22）接通。 当V1下降到或低于低电压电平时，第一压控开关（24）用线路（26）上的开关信号来关断欠压开关（22）。 当电池电压V1低于预定的过电压电平时，第二电压控制开关（30）保持过压开关（28）接通。 当V1达到或超过过电压电平时，第二压控开关通过线路（34）上的开关信号关断过电压开关（28）。
