Embodiment Construction

[0020] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0021] The invention discloses a method for charging a battery in a mobile terminal. In the method, the initial state of charging controls the power supply current output by the power supply terminal of the electronic device to be a first preset value, and judges the operation of the system by detecting the charging current of the battery in real time. state and the charging state of the battery, and keep the supply current at the first preset value when the system of the electronic device is in the standby state, and adjust the magnitude of the supply current so that the battery is in the working state or busy state Low-power charging state or stop charging, so that the temperature of the electronic device will not be too high due to batte...

Abstract

The invention discloses a battery charging method which is used for charging a battery of an electronic device. The battery charging method includes the following steps of controlling a power supply current output by a power supply end of the electronic device to be a first preset value in an original state, detecting a charging current of the battery, judging a system operation state of the electronic device and a charging state of the battery according to the charging current size, reducing the power supply current magnitude so that the battery is in a small power charging state or stops charging when the system is in a working state or a busy state, keeping the power supply current as the first preset value when the system is in a stand-by state or a small power consumption state, thereby achieving an aim of reducing temperature rise of a whole machine by dynamically adjusting the charging current under the charging state so that the temperature of the system can not be too high even though the battery is charged when the system works. The invention further discloses the corresponding battery charging system and a mobile terminal with the battery charging system.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a battery charging method and a battery charging system for charging electronic equipment. Background technique [0002] With the development of smart phones, large screens, high-resolution display screens, high-pixel cameras, and some are even equipped with external ISP image processing chips to improve the photo effect. Support HD video playback. At the same time, the functions of mobile games are becoming more and more powerful. Many games that could only be played on computers before can also be played on mobile phones. All of these will greatly increase the power consumption of the mobile phone, that is, the current consumption is very large, and the temperature rise of the mobile phone will increase accordingly. Especially now that smart phones are becoming more and more light and thin, the heat dissipation space of mobile phones is further compressed, which makes the thermal d...
