Charging circuit and formation cabinet with same

Abstract

The utility model discloses a charging circuit and a formation cabinet with the charging circuit, and the charging circuit comprises a boosting chip used for boosting current, a first triode, a second triode, and a capacity grading battery used for performing formation and capacity grading charging. The boost chip is arranged to boost the input current and then output the boosted current to the first triode, so that the first triode drives the second triode, the first triode and the second triode supply power separately, and finally the second triode supplies power to the capacity grading battery. According to the charging circuit, the charging effect of the charging circuit can be achieved through power supply with lower voltage, the problems that in the prior art, the efficiency of a charging mode of achieving charging and discharging control only through two triodes is low, and meanwhile much energy is wasted are solved, and the power consumption of the charging circuit is reduced.
