Problems solved by technology

[0004] However, the above-mentioned electronic interfaces rely on the contact of the metal contact piece to complete the electrical connection. When the charging current flows, the contact piece will heat up due to the thermal effect of the resistance. When the charging current or charging voltage is too large, the temperature of the electronic interface may be too high. Damage to the device or even explosion will seriously affect the safety of use

Abstract

An embodiment of the present invention provides a power management method and device and electronic equipment, and the charging security can be improved. The method is implemented in the electronic equipment that receives the charging of a power adapter through a charging cable. The method includes a step of determining the temperature of a charging interface, wherein the charging interface comprises at least one interface in the group consisting of an interface of the power adapter for electrically connecting the charging cable, an interface of the charging cable for electrically connecting to the power adapter, an interface of the charging cable for electrically connecting the electronic equipment, and an interface of the electronic equipment for electrically connecting the charging cable, and a step of managing the power of the electronic equipment according to the temperature of the charging interface.

Description

technical field [0001] The present invention relates to the technical field of charging, and more particularly, to a method, device and electronic equipment for power management. Background technique [0002] Currently, electronic devices such as mobile phones are usually equipped with a rechargeable battery, so that the battery can be charged through a power adapter. [0003] When charging, the power adapter converts AC power into DC power of a specified voltage and transmits it to the electronic device. In addition, an electronic interface is generally provided in the power adapter and the electronic device, and can be electrically connected to a charging cable through the electronic interface, so that charging can be performed through the charging cable. [0004] However, the above-mentioned electronic interfaces rely on the contact of the metal contact piece to complete the electrical connection. When the charging current flows, the contact piece will heat up due to the...
