Abstract

본 발명은 충전용 배터리의 자동 충,방전 기술에 관한 것으로, 마이콤(18)이 사용자가 설정하는 충방전 횟수를 인지한후, 충전전압 검출부(13), 방전전압 검출부(17)를 통해 충, 방전 전압을 검출하여 충전제어부(12), 방전제어부(15)를 통해 충, 방전 동작이 반복 수행되게 함으로써 베터리의 충전용량을 회복시킬 수 있게 한 것이다.The present invention relates to a technology for automatically charging and discharging a rechargeable battery. After recognizing the number of charge / discharge cycles set by a user, the microcomputer 18 charges and charges the battery through a charge voltage detector 13 and a discharge voltage detector 17. The charging and discharging operations are repeatedly performed through the charge control unit 12 and the discharge control unit 15 by detecting the discharge voltage, thereby recovering the charging capacity of the battery.
