Abstract : the rechargeble batteries are used for backup power internal electrically equipments and instruments . but batteries lifetime usually is shorten by overwork and then malfunctions of equipment are induced . to avoid the complexion described above , the protection circuit against overwork is designed . it is based upon the voltage comparator and regulator . it will light up a red led when the volume of the batteries discharged close upon 50 % ; it will switch off the load automatically when it discharged closing to 80 % of their energy capacity , thus overwork of batteries can be avoided and lifetime may be extended
文摘:用蓄电池做后备电源的系统(或设备) ，常因过放电导致电池提前报废而造成设备故障.根据电池电压随容量变化的规律,利用电压比较器和电压基准源设计制作了电池放电保护电路，当电池放电量接近容量的50 %时，启动预警信号；当电池放电量达到容量的80 %时,电路自动切断负载，防止电池过度放电,延长电池寿命，保证系统（或设备）在供电恢复正常后能正常运行
