Problems solved by technology

[0015] The problem in the above fast charging process is that the charging voltage and current pair can only be selected according to the configuration of the user, that is, the charging power can be selected, and the charging power cannot be adaptively adjusted according to the heating conditions of the important components of the electronic equipment. In this way, For example, when the battery temperature is too high and the maximum charging power is still charged, not only the safety of charging cannot be guaranteed, but it may also cause damage to the battery and affect the health of the battery.

Abstract

The invention discloses a charging power adjustment method and apparatus used for an electronic device and the electronic device. The method comprises the steps of identifying whether a charger inserted in a USB interface is a PD (Power Delivery) charger supporting quick charging, and if yes, obtaining a current temperature value of each set device; determining corresponding charging power according to the current temperature value of each set device; selecting lowest charging power as target charging power from all the determined charging power; selecting a voltage and current pair matched with the target charging power from all voltage and current pairs supported by the PD charger; and sending a load part, loaded to a charging request message, of the selected voltage and current pair to the PD charger. According to the method and apparatus as well as the electronic device, the charging power can be adjusted in real time according to a device heating condition, so that the charging safety and the device health degree can be effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of USB-PD fast charging, and more specifically, to a charging power adjustment method for electronic equipment, a charging power adjustment device for electronic equipment, and an electronic equipment. Background technique [0002] USB-PD (Power Delivery) charging is an emerging fast charging technology, which is mainly implemented through the Type-C interface. In order to facilitate the understanding of USB-PD charging technology, the following will first explain the basics of the Type-C interface. structure. [0003] The biggest feature of the Type-C interface is that it supports the "front and back insertion" function that can be inserted from both sides. Its A side and B side each have 12 pins. The layout of each pin is shown in Table 1: [0004] Table 1: [0005] [0006] Among them, TX1+, TX1-, RX1+, RX1-, TX2+, TX2-, RX2+, RX2- are four pairs of differential signal pins, GND is a ground p...
