A mobile terminal and charging method

Abstract

The embodiment of the present invention discloses a mobile terminal and a charging method. The mobile terminal includes: a charging interface, a switching control switch, a charging chip, and a processor; wherein, the processor is used to control switching when the preset parameter is not within the direct charging threshold range. The control switch disconnects the direct charging path, and starts the charging chip to charge the chip for the battery; when the preset parameters are within the direct charging threshold range, the processor is used to control the switching control switch to connect the direct charging path, and according to the input current of the switching control switch , the output voltage of the charger and the input voltage of the switching control switch to obtain a direct charging current, so that the charger performs direct charging for the battery according to the direct charging current. Through this solution, the charging mode can be switched according to the preset parameters, thereby reducing the temperature rise of the mobile terminal during the charging process, reducing the loss caused by the charging line, avoiding the problem of serious heating of the charging line, and avoiding the occurrence of charging lines. Safety hazards caused by overheating.

Description

technical field [0001] The present application relates to the technical field of mobile terminals, in particular to a mobile terminal and a charging method. Background technique [0002] With the development of science and technology, a variety of mobile terminals (such as smart phones and iPADs, etc.) have penetrated into people's daily life and work, bringing many conveniences to people's life and work. [0003] At present, mobile terminals usually use rechargeable batteries to power their own systems, and usually use the following two methods to charge the rechargeable batteries: In the first charging method, connect the mobile terminal to the host (such as a computer, etc.), and use the host to Mobile terminal charging, however, when using this charging method, the charging current output by the host is small, and it takes a long time to charge; in order to overcome the shortcomings of the first charging method, the second charging method can also be used. It is necessa...

Problems solved by technology

[0005] In order to solve the problem in the prior art, when the charger is used to charge the mobile terminal, the efficiency loss of the charging chip is transformed into the temperature rise of the mobile terminal, which causes the temperature of the mobile terminal to rise, and when a large current is used for charging, the charging line connected to the charger The requirements are higher, and some charging lines tend to generate serious heat and cause a large loss. The present invention discloses a mobile terminal and a charging method through the following embodiments
