Embodiment Construction

[0049] 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.

[0050] The first embodiment of the present invention discloses a mobile terminal. see figure 1 A schematic structural diagram of a mobile terminal is shown, and the mobile terminal includes: a charging interface 100 , a switching control switch 200 , a charging chip 300 and a processor 400 . In addition, a battery 500 is provided in the mobile terminal, and the battery 500 is a rechargeable battery.

Abstract

The embodiments of the invention disclose a mobile terminal and a charging method. The mobile terminal comprises a charging interface, a switching control switch, a charging chip and a processor; whena preset parameter is not within a direct charging threshold range, the processor is used for controlling the switching control switch to cut off a direct charging closed circuit and starting the charging chip to perform chip charging on a battery; and when the preset parameter is within the direct charging threshold range, the processor is used for controlling the switching control switch to turn on the direct charging closed circuit, obtaining direct charging current according to the input current of the switching control switch, the output voltage of a charger and the input voltage of theswitching control switch, so as to enable the charger to perform direct charging on the battery according to the direct charging current. With the mobile terminal and the charging method of the invention adopted, a charging mode can be switched according to the preset parameter, and therefore, the temperature rise of the mobile terminal during a charging process can be reduced; the loss of a charging line can be decreased; the problem of serious heat emission of the charging line can be avoided; and safety hidden hazards caused by the heat emission of the charging line can be avoided.

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...
