Abstract

The invention provides an electronic device, a power adapter, a charging system and a charging method. Wherein, the charging system includes: an electronic device; and a power adapter for charging the electronic device. Wherein, the electronic device and the power adapter are capable of two-way communication; the electronic device sends a health check command to the power adapter, and the power adapter performs a self-health check operation according to the health check command and reports the check result to the electronic device. The embodiment of the present invention can reduce the charging risk of electronic equipment.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to an electronic device, a power adapter, a charging system and a charging method. Background technique [0002] If the AC-DC (Alternating Current-Direct Current, AC-DC) adapter uses inferior or insulation aging circuit components, then the AC-DC adapter may transmit AC current or a large current pulse (surge pulse) to the charged electronics. equipment, thereby creating a danger to the user. In addition, when the output current of the AC-DC adapter is greater than the capacity of the connector / cable, the connector of the electronic device may suffer from the risk of being burned. Contents of the invention [0003] In view of this, an embodiment of the present invention provides an electronic device, a power adapter, a charging system, and a charging method to reduce charging risks; wherein, the electronic device and the power adapter can communicate with each other. [0004] T...
