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:用蓄電池做后備電源的系統（或設備） ，常因過放電導致電池提前報廢而造成設備故障.根據電池電壓隨容量變化的規律，利用電壓比較器和電壓基準源設計製作了電池放電保護電路，當電池放電量接近容量的50 %時，啟動預警信號；當電池放電量達到容量的80 %時，電路自動切斷負載，防止電池過度放電，延長電池壽命，保證系統（或設備）在供電恢復正常后能正常運行 -
