Abstract
본 발명은 충전기로 배터리를 충전하고, 상기 충전된 배터리로 부하를 구동시키는 배터리전원공급시스템의 배터리 상태측정장치에 관한 것으로, 충전시에 충전전류를 감지하여 배터리의 충전상태를 검출하는 충전상태검출부(10)와 충전된 배터리에 부하를 인가할 때는 분배된 배터리 전압을 제1기준전압(Vref1)과 비교하여 과방전상태를 검출하고, 무부하시에는 분배된 배터리 전압을 제2기준전압(Vref2)과 비교하여 과방전상태를 검출하는 방전상태검출부(20)를 구비하여 충전상태와 방전상태를 정확하게 검출하여 과방전을 방지하고 배터리의 사용 효율을 증가시킨다.The present invention relates to a battery state measuring device of a battery power supply system that charges a battery with a charger and drives a load with the charged battery. The present invention relates to a charge state detection unit for detecting a state of charge of a battery by detecting a charging current during charging. When the load is applied to the charged battery 10, the divided battery voltage is compared with the first reference voltage Vref1 to detect an over-discharge state, and at no load, the distributed battery voltage is measured as the second reference voltage Vref2. Comparing with the discharge state detection unit 20 for detecting an over-discharge state accurately detects the state of charge and the discharge state to prevent over-discharge and increase the use efficiency of the battery.
