摘要： Circuit groups for preventing a battery from being deteriorated in efficiency due to a charging and discharging of each of secondary batteries is incorporated in a battery protection circuit for protecting a plurality of batteries connected in series to thereby extend a life of the battery. The battery protection circuit incorporates therein power down means for extending a time in which a voltage of a remaining capacity becomes 0V as much as possible by causing a current to flow only in the minimum circuit when the battery is overdischarged. Also, when a trouble such as a momentary overcurrent or the like is detected, the circuit can be prevented from set in the power down mode.

摘要： Circuit for preventing overcharge and overdischarge of secondary batteries is disclosed. Overcharge detecting comparators COMP2 and COMP4 each having a hysteresis circuit 1 are connected between positive and negative electrodes of series-connected secondary batteries Abat and Bbat, and overdischarge detecting comparators COMP1 and COMP3 each having a hysteresis circuit 2 are connected also between the above electrodes. Transistors T1, T2 and a resistor R are connected between the batteries for overflow of overcharge and balance of overdischarge. Upon detection of any overcharge by the comparator COMP2 or COMP4, the charge current is interrupted by a transistor T6, and simultaneously the overcharge overflow is discharged by the hysteresis circuit until the battery voltage is lowered to the hysteresis voltage. And after the discharge, the transistor T6 is turned on to resume recharging the batteries. Meanwhile, upon detection of any overdischarge by the comparator COMP1 or COMP3, the discharge current is interrupted by a transistor T5. Thus the overcharge and the overdischarge can be balanced by the hysteresis circuits 1 and 2 respectively.

摘要： A battery protection circuit has a condition detecting circuit which detects a voltage across a secondary cell or cells and compares the detected voltage with a reference voltage to detect an overdischarged condition or an overcharged condition of the secondary cell or cells. A control unit controls a first switching element for cutting off a discharging current and a second switching element for cutting off a charging current based on a detected condition of the secondary cell or cells. A third switch element cuts off electric power supplied to the condition detecting circuit. The third switch element is rendered nonconductive when the overdischarged condition is detected by the condition detecting circuit.

摘要： An overcharge preventing device and an overdischarge preventing device for a nonaqueous electrolyte secondary battery having voltage detectors and are provided to respectively detect terminal voltages of batteries connected in series. A switch is provided in series to the batteries between a common terminal and a charge terminal. When the terminal voltage of at least one of the batteries exceeds a battery design voltage in charging the batteries, the switch is turned off in response to an output from the corresponding voltage detectors, thereby cutting off a charging current. Further, a voltage detector is provided to detect a terminal voltage of the series connected batteries. A switch is provided in series to the batteries between the common terminal and a discharge terminal. When the terminal voltage of the batteries becomes equal to or less than a set voltage in discharging the batteries, the switch is turned off in response to an output from the voltage detector, thereby cutting off a discharging current.
