Title:

CHARGING APPARATUS FOR ELECTRONIC DEVICE AND POWER ADAPTER FOR ELECTRONIC DEVICE

Document Type and Number:

WIPO Patent Application WO/2015/113341

Kind Code:

A1

Abstract:

The present invention relates to the technical field of charging. A charging apparatus for an electronic device (200) and a power adapter (100) for the electronic device (200). In the process of charging a battery (201) in a normal charge mode after the power adapter (100) is powered on reset, when an output current value of the power adapter (100) is within a normal current range at a preset time interval, the power adapter (100) carries out fast charge inquiry communication with the electronic device (200); after the electronic device (200) sends a fast charge command to the power adapter (100), the power adapter (100) adjusts the output voltage according to voltage information of the battery (201) fed back by the electronic device (200); and when the output voltage meets a fast charge voltage condition preset by the electronic device (200), the power adapter (100) adjusts the output current and the output voltage to charge the battery (201) according to a fast charge mode, and therefore the purpose of quickly charging the battery (201) to shorten the charging time is achieved.
