Problems solved by technology

[0004] Excessive charging voltage and charging current will cause potential safety hazards. For example, when the current at the charging interface exceeds 5A, the current will easily break through the air and generate an arc during the process of pulling out the charging interface.

Abstract

The invention provides a charging method, device and equipment and a storage medium, and belongs to the field of electronic equipment. The method comprises the steps of when a terminal is charged at afirst charging power, detecting a first moving acceleration of the terminal through a motion sensor; and when the first moving acceleration is greater than a first acceleration threshold value and the moving time is greater than a time threshold value, determining corresponding second charging power according to the first acceleration threshold value, and switching the charging power of the terminal from the first charging power to the second charging power, wherein the second charging power is less than the first charging power. According to the method, whether the terminal is in a charginginterruption state or not is judged through the moving acceleration and the moving time of the terminal, and when it is determined that the terminal is in the charging interruption state, the chargingpower of the terminal is reduced, so that a charging interface of a charging line can be safely pulled out, and potential safety hazards caused by overlarge charging voltage and charging current during high-power charging are avoided.

Description

technical field [0001] The present disclosure relates to the field of electronic devices, and in particular, to a charging method, device, device, and storage medium. Background technique [0002] Currently, users have higher and higher requirements for fast charging of mobile terminals, and higher and higher charging speeds of mobile terminals have become a development trend in the future. [0003] The principle of fast charging of mobile terminals is to use high-power charging. The greater the power, the faster the charging speed; and as the charging power increases, the charging voltage and charging current will also increase. [0004] Excessive charging voltage and charging current will cause safety hazards. For example, when the current at the charging interface exceeds 5A, the current will easily break through the air and generate an arc during the process of pulling out the charging interface.
