Abstract
A charging device, a charging method and a terminal, an output end of the main charging circuit and output ends of the at least two secondary charging circuits are connected to a battery of an electronic device, and the output end of the main charging circuit is used for supplying power for an internal chip of the electronic device, disconnecting a connection between the main charging circuit and the battery when a voltage of the output end of the main charging circuit reaches a voltage required by the internal chip, and supplying power for the battery through the output ends of the at least two secondary charging circuits, in this way, charging time is shortened and a purpose of fast charging a battery is achieved.
