A charging method for realizing automatic power control

Abstract

The invention provides a charging method for realizing automatic power control, which comprises the following steps of: setting an initial value of a charging current; detecting an output voltage of a mobilephone charger and a voltage of a mobilephone battery, and acquiring a current charging current of the mobilephone according to the rated power of the mobilephone charger; comparing the current charging current with the initial value of the charging current; and regulating the value of the current charging current of the mobilephone according to the comparison result, and setting the current charging current of the mobilephone into a maximum charging current allowably set by the rated power of the mobilephone charger. According to the mode and the charging method for realizing the automatic power control, the value of the current charging current of the mobilephone is regulated according to the comparison result between the current charging current and the initial value of the charging current to further automatically regulate the charging current of the mobilephone battery, so that the mobilephone can be compatible with mobilephone chargers with different output powers for charging, and overhigh output voltage during charging of the mobilephone is avoided.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging method for realizing automatic power control. Background technique [0002] With the development of science and technology, mobile phones, as a hot-selling electronic product, have been popularized by all kinds of people. As an integral part of mobile phone accessories, the mobile phone charger matching the mobile phone is indispensable. [0003] At present, there are many kinds of mobile phone chargers on the market, and the electrical characteristics of mobile phone chargers are different, especially the power curve is different. The Ministry of Industry and Information Technology started to customize a unified interface standard to reduce the situation that the original mobile phone charger cannot be used due to the purchase of different mobile phones by users. The mobile phone chargers of the prior art only allow users to plug in mobile phone chargers of...

AI Technical Summary

Problems solved by technology

The mobile phone chargers of the prior art only allow users to plug in mobile phone chargers of different brands on a mobile phone structurally, but there are also the following problems electrically: when the output voltage of the mobile phone charger is too high, the charging circuit of the mobile phone The energy consumed will increase, causing its temperature to increase, which in turn affects the reliability of the mobile phone charger and the mobile phone itself
