Embodiment Construction

[0054]The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0055] Such as figure 1 Shown is a schematic diagram of a charging circuit with a dual-cell architecture, including: two voltage conversion chips 101 (HV2:1CP) and a control chip 102 (buck-boost charger IC). When the charging power is above 50W, the power provided by the charging device The battery is charged by two voltage conversion signals in parallel and the control chip IC, and the charging efficiency mainly depends on the loop loss and the efficiency of the switching capacitor....

Abstract

The present application provides a charging method, including: applied to an electronic device, the electronic device includes at least three charging circuits, any two charging circuits realize different charging power to charge the battery, one charging circuit corresponds to a charging strategy, The charging method includes: acquiring the charging environment parameters of the electronic device; switching the charging strategy used by the electronic device from the first charging strategy to the second charging strategy at the current moment based on the charging environment parameters satisfying a predetermined switching condition strategy, the charging power of the first charging strategy is higher than the charging power of the second charging strategy. In this solution, multiple charging circuits are set up. When the temperature of the electronic device is high during the charging process, it is switched to another charging strategy with lower charging power. Compared with directly reducing the charging power for the first charging strategy, for charging The effect on efficiency is small, and the heating of the device is reduced under the premise of ensuring the charging efficiency.

Description

technical field [0001] The present application relates to the field of electronic equipment, and more specifically, relates to a charging method, device and electronic equipment. Background technique [0002] With the development of electronic technology, fast charging of electronic devices is widely welcomed by users as a fast charging method. [0003] However, the higher the system charging power of the electronic device, the higher the charging heat. Taking mobile phones as an example, when the charging power of the mobile phone system rises above 50W (watts), a dual-cell architecture must be used to continue to increase the charging power. The charging IC (integrated circuit) architecture used is a 2:1 switch The charging efficiency of capacitors and ICs is about 96% to 97% between 10W and 100W, and the lower the efficiency is in the lower power range, the greater the heat generated by the system. [0004] Therefore, there is an urgent need for a charging method that c...
