Abstract

본 발명은 2차전지의 충전기 회로에 있어서 충전모드 절환회로에 관한 것으로, 충전시는, 정전류, 충전완료후에는 정전압 충전을 각각 행하여 신속한 충전을 할 수 있게하고, 밧데리의 보호를 할 수 있게 한 것이다.The present invention relates to a charging mode switching circuit in a charger circuit of a secondary battery, and when charging, it is possible to perform a rapid charging by performing constant voltage charging at the time of constant current and after charging is completed, and to protect the battery. will be.

즉, 정전류 및 정전압제어부를 갖추고, 정전류 충전시작을 감지하는 재충전감지부와 완료를 감지하는 완충전압 감지부를 두어, 밧데리를 사용도중 충전기에 결합하면 이때 흐르는 전류를 감지하여 정전류 충전모드로 바뀌고 완료전압까지 전압이 상승하면 정전압모드로 절환하여 부동충전을 행하게 함으로써 전화기 자기의 충전기와 일반니카드및 납축전지의 충전기에 중요한 용도로 쓰이게 된다.That is, it has a constant current and constant voltage control unit, and it has a recharge detector to detect the start of constant current charging and a buffer voltage detector to detect the completion of the battery. When the voltage rises up to the constant voltage mode, the floating charge is to be used as an important use in the charger of the phone itself, chargers of general Nicards and lead acid batteries.
