Abstract
The present invention discloses a charging control circuit, comprising an external power source, a switching circuit, and a charging path circuit comprising a first output circuit and a second output circuit, wherein the external power source is configured to charge a secondary battery through the first output circuit and charge a load through the second output circuit, and the switching circuit is configured to decouple the secondary battery from the load when the external power source is available. Meanwhile, the present invention discloses a charging control method and an electronic device; according to the present invention, because the two output circuits are coupled to the secondary battery and the load, respectively, the load will not divide up the charging current, thereby effectively shortening the charging time and prolonging the service life of the secondary battery.
