Abstract

The embodiment of the invention discloses a charging control method and electronic equipment. The electronic device has an electric energy storage unit; the method includes: the electronic device detects that the first interface is connected to the first power supply device, and detects that the second interface is connected to the second power supply device; The first output parameter of the first power supply device, and obtain the second output parameter of the second power supply device through the second interface; obtain the input parameter of the electric energy storage unit; when the first output parameter and the When the second output parameter satisfies a preset condition, compare the input parameter with the first output parameter, and compare the input parameter with the second output parameter; select the first power supply device or the The second power supply equipment establishes a power transmission link with the first power supply equipment or the second power supply equipment.

Description

technical field [0001] The invention relates to charging technology, in particular to a charging control method and electronic equipment. Background technique [0002] At present, more and more electronic devices (such as notebook computers) support at least two kinds of power adapters, that is, electronic devices have at least two kinds of power adapter interfaces, such as direct current (DC) interface and universal serial bus type-C (USB Type-C )interface. When at least two power adapters are connected to the electronic device, usually, the electronic device will select the power adapter with the highest output power for charging. If the output power is the same, the electronic device will select the first connected power adapter for charging. Compared with the power adapter that is not connected, the connected power adapter may have the problem of low charging efficiency. Contents of the invention [0003] In order to solve the existing technical problems, the embodi...
