The power adapter comprises a communication interface and charges via the communication interface a battery of the electronic equipment; during charging a battery, the power adapter is configured to: first charge the battery in a regular charging mode; when an output current value of the power adapter falls within a regular current range for a predefined time period, send a quick charge inquiry instruction to the electronic equipment; after receiving a quick charge command sent by the electronic equipment, adjust an output voltage according to battery voltage information fed back by the electronic equipment; and if the output voltage meets a quick charge voltage requirement predefined, adjust an output current and the output voltage according to a quick charge mode so as to charge the battery.

Battery charging apparatus and method

The present invention provides a charging system that includes a charging adapter and a mobile terminal. The charging adapter includes: a second USB interface; and an adjusting circuit for rectifying and filtering the mains supply to obtain an original power signal, for performing a voltage adjustment on the original power signal, and for outputting a power signal after the voltage adjustment. The mobile terminal includes a first USB interface. P first power wires in the first USB interface and P second power wires in the second USB interface are correspondingly coupled, and Q first ground wires in the first USB interface and Q second ground wires in the second USB interface are correspondingly coupled. Because each first power wire and a corresponding second power wire are coupled, at least two charging circuits can be provided, and the charging system supports charging with a large current more than 3 A.
