Abstract

본 발명은 배터리 충전시 항상 만충전할 수 있도록 2단계 충전을 수행한다. 이를 위하여 충전전원을 입력하는 제1단자와 충전전류를 발생하는 제2단자 사이에 충전전류를 발생하는 수단을 연결하고, 제2단자에 배터리를 연결하여 충전동작을 수행한다. 이때 충전전류를 발생하는 수단은 스위칭소자를 구비하고 급속충전전류를 발생하는 수단과 정상충전전류를 발생하는 수단으로 구성된다. 그러면 제2단자에 접속되고 기준전원을 구비하는 제어수단은 배터리의 충전전압을 기준전압과 비교하여 충전완료 감지시 상기 스위칭소자를 오프시켜 급속충전전류를 차단한다. 따라서 최초 1단계에서는 상기 급속충전전류와 정상충전전류가 혼합되어 충전동작을 수행하고, 기준전압 이상을 충전된 경우에는 정상충전전류로 충전동작을 수행하여 부족충전을 보상한다.The present invention performs a two-stage charging so that the battery is always fully charged when charging. To this end, a means for generating a charging current is connected between a first terminal for inputting charging power and a second terminal for generating a charging current, and a charging operation is performed by connecting a battery to the second terminal. In this case, the means for generating the charging current includes a switching element, means for generating a rapid charging current, and means for generating a normal charging current. Then, the control means connected to the second terminal and provided with the reference power source compares the charging voltage of the battery with the reference voltage to turn off the switching element when detecting the completion of charging to cut off the rapid charging current. Therefore, in the first stage, the fast charging current and the normal charging current are mixed to perform a charging operation, and when charged above the reference voltage, the charging operation is performed with the normal charging current to compensate for the insufficient charging.
