AI Technical Summary

Technical Problem

During the charging process of a terminal device with the screen on, the system consumes different amounts of power under different usage scenarios. This means that the charging current under uniform temperature control cannot meet the charging needs of high-power scenarios, affecting charging speed and user experience.

Method used

By detecting the first current in the current application scenario, the resulting temperature change value is determined, and based on factors such as the temperature change threshold and heat dissipation coefficient, the allowable second current is calculated. In this way, the charging current is adjusted to meet the temperature change requirements of different scenarios and ensure charging speed.

Benefits of technology

It enables the charging current to be adjusted according to actual needs in different application scenarios, improving charging speed and user experience, and avoiding the problem of slowed charging speed caused by uniform temperature control.

Abstract

This disclosure relates to a charging method, charging device, and storage medium. The charging method is applied to a terminal and includes: detecting a first current and determining a first temperature change value generated by the first current, wherein the first current is the discharge current of the terminal when charging in the current application scenario; determining a second temperature change value allowed to be generated by the terminal battery based on a temperature change threshold and the first temperature change value; determining a second current based on the second temperature change value; and charging the terminal with a charging current that satisfies the first current and the second current. Through the embodiments of this disclosure, different charging currents can be determined for different application scenarios to ensure the charging speed in that scenario.
