Problems solved by technology

[0005] However, the NTC of the battery can only reflect the heating of the mobile phone near the battery compartment, but the temperature of the screen area where the user touches the operation, the area where the user holds the mobile terminal, etc. that are prone to heat or heat-sensitive parts cannot reflect the temperature. Improve the bad user experience caused by the overheating of the above parts

[0035] see figure 1 , propose the first embodiment of the fast charging method of the present invention, the method includes the following steps:

[0036] Step S101: During the charging process, detect the temperature of at least two parts of the terminal device

[0037] In this step S101, a plurality of temperature sensors are used to respectively detect temperature change data of a plurality of parts of the terminal device. For example, the temperature of the battery of the terminal device, the front screen, and the hand-held area on the back or side can be detected separately, which is easy to heat or heat-sensitive parts. The temperature sensor can use the off-the-shelf temperature sensor built into the motherboard (such as AP motherboard) and multi-chip components (such as PM chip component) to reduce the cost.

[0046] see figure 2 , propose the second embodiment of the fast charging method of the present invention, the method includes the following steps:

[0047] Step S201: During the charging process, detect the temperature of at least two parts of the terminal device

[0048] Step S202: Determine whether the temperature of each part reaches its respective threshold

[0049] Step S203: Judging whether it is currently in the constant current charging stage

[0050] Fast charging usually includes three stages of constant current charging, constant voltage charging and trickle charging. Among them, the constant current charging stage is also called the fast charging stage, and the charging current is the largest at this time; the constant voltage charging stage is also called the supplementary charging stage or the slow charging stage, and the charging current is gradually smaller at this time; The charging current is charged until certain conditions are met and the charging ends....

Abstract

The invention discloses a quick charging method and a mobile terminal. The quick charging method comprises the following steps of detecting the temperature of at least two parts of a terminal device in the charging process; judging whether the temperature of each part reaches a respective threshold value or not; adopting a preset charging strategy according to the judgment result. The preset charging strategy is adopted by detecting the temperature of each part of the terminal device and comprehensively considering the temperature variation situation of each part. When the temperature is excessively high, the overheat protection is carried out, and the charging is stopped or the charging current is reduced; when the temperature is excessively low, the charging current is increased, and the charging speed is accelerated. The safety problem caused by overheating of the charging and the leaded unfavorable user experience can be avoided, and the charging efficiency can be increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a fast charging method and a mobile terminal. Background technique [0002] With the increase of battery capacity of mobile terminals, how to increase the charging speed has become a concern of people. In recent years, fast charging technology has been continuously developed. The essence of the so-called fast charging is to shorten the charging time of the battery by increasing the charging current value in the constant current charging phase of the battery. At present, the constant current charging current of mobile terminals has continuously increased from below 500mA to above 2000mA. [0003] The continuous increase of the charging current has indeed brought about an increase in the charging speed, but it has also brought about safety hazards and poor user experience due to charging heat. Moreover, the greater the charging current, the more serious the heat caused by ...
