Embodiment Construction

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0036] At present, in a charging system composed of an electronic device and a charger, as the charging time prolongs, the temperature of the charger will gradually increase. In order to ensure the safety of the charger, there is a temperature threshold set in the charger, which is called the derating point or over-temperature protection point. The electronic device will obtain the derating point set in the charger and detect the temperature of the char...

Abstract

The embodiment of the invention discloses a charging method, a charger and electronic equipment. The method comprises the steps of obtaining a derating point of the charger under the condition of establishing connection with the charger, wherein the derating point is an actual derating point obtained by testing the charger; sending a temperature acquisition instruction to the charger; obtaining aresponse message returned by the charger, wherein the response message comprises an actual temperature value detected by the charger in the current period; and under the condition that the actual temperature value reaches the derating point, sending a first power reduction instruction to the charger, so that the charger reduces the self power according to the first power reduction instruction. Byutilizing the embodiment of the invention, the problems of low safety in the charging process and short service life of the charger due to temperature rise of the charger can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the field of device charging, and in particular, to a charging method, a charger and an electronic device. Background technique [0002] At present, in a charging system composed of an electronic device and a charger, as the charging time prolongs, the temperature of the charger will gradually increase. [0003] Because high temperature is easy to cause damage to various components in the charger and reduce the service life of the charger, and there are certain safety hazards in the charger at high temperature, therefore, it is necessary to solve the problems caused by the temperature rise of the charger. The safety of the charging process is low and the service life of the charger is short. Contents of the invention [0004] Embodiments of the present invention provide a charging method, a charger, an electronic device, and a medium, so as to solve the problems of low safety in the charging process...
