Mobile phone as well as charging circuit and method of cell thereof

Abstract

The invention provides a charging method of a cell of a mobile phone, comprising the following steps of: detecting the voltage of the cell of the mobile phone; comparing the voltage of the cell with a preset voltage, judging the charging mode of the cell of the mobile phone according to a comparison result, and setting the first charging current of the cell of the mobile phone according the charging mode. The invention also provides the mobile phone and a charging circuit of the cell thereof. According to the mobile phone as well as the charging circuit and method of the cell thereof, the charging current of the cell of the mobile phone can be automatically adjusted, so that the mobile phone can be compatible with mobile phone chargers with different output powers to charge.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging method for a mobile phone battery. 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 insert mobile phone chargers of different b...

AI Technical Summary

Problems solved by technology

The mobile phone chargers of the prior art only allow users to insert mobile phone chargers of different brands on a mobile phone structurally, and there are also two problems electrically: when the output power of the mobile phone charger is less than the charging power of the mobile phone battery , so the mobile phone charger cannot reach the charging power of the mobile phone battery, causing the mobile phone charger to fail to work normally; , leading to the inability to reach the maximum efficiency of the mobile phone charger

[0004] Therefore, it is necessary to provide a mobile phone charging circuit to solve the problem that the mobile phone charger in the prior art is only suitable for mobile phones whose charging power is equal to the output power of the mobile phone charger
