Embodiment Construction
[0022] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.
[0023] In a preferred embodiment of the present invention, the charging device is used to supplement the electric energy of the mobile terminal. The charging unit includes:
[0024] - charging chip
[0025] The charging chip has a built-in logic control unit, which can issue control commands to other components in the charging device to control the charging process.
[0026] - Current regulation unit
[0027] The current adjustment unit is located in the charging device, which can adjust the output current of the charging device, for example, increase or decrease. When the surface temperature of the main board or cover of the mobile terminal is high, the control components of the mobile terminal such as the CPU will detect The temperature of the mobile terminal, and when the temperature is too high and exceeds a certain pr...

The present invention provides a charging device for a mobile terminal. The device comprises: a current regulation unit configured to reduce the output current of the charging device to a first current I1 and allow the charging device to output a first output power P1; and a voltage regulation unit configured to reduce the output voltage Vbus of the charging device, wherein when the output voltage Vbus is reduced, the current regulation unit rises the output current to a second current I2 to allow the charging device to output a second output power P2 being equal to the first output power P1, and the charging efficiency [Mu]2 of the second output power P2 is larger than the charging efficiency [Mu]1 of the first output power P1. The present invention further provides a charging method for a mobile terminal. Through adoption of the technical scheme, the charging device and charging method for the mobile terminal can reduce the temperature of the mobile terminal at charging and prolong the service life of the mobile terminal in the condition without influencing the charging time and the charging efficiency.
Description
technical field [0001] The invention relates to the field of mobile terminals, in particular to a charging device and a charging method for a mobile terminal. Background technique [0002] With the continuous development of communication technology, mobile terminals affect communication and exchanges in various fields. As a mobile device, its battery life has always been a concern of users. When the mobile terminal is used for a long time, the battery that has been discharged for a long time needs to be charged. With the increasing pace of life, users have higher requirements for charging time, but the fast charging mode requires a large charging power, which makes the battery and the mobile terminal heat up, and the mobile terminal will be shortened when the temperature is too high. The service life of the internal battery. [0003] Therefore, there is a need for a new type of charging device and charging method, which can reduce the temperature of the mobile terminal du...
