Embodiment Construction

[0031] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] In this embodiment, in order to make full use of the characteristics of the dynamically adjustable output voltage of the direct charging source adapter to achieve a significant increase in charging speed, firstly, the hardware of the mobile terminal with a built-in rechargeable battery is modified so that the mobile terminal can support conventional charging. Mode, that is, the battery is charged through the power management chip inside the mobile terminal; it can also support the direct charging mode, that is, the charging power is directly delivered to the battery, and the battery is directly charged with a large current. Then, according to the modified hardware circuit, a software program is designed to dynamically adjust the charging voltage output by the direct charging source adapter according to the real-tim...

Abstract

The invention discloses a quick-charging method and a mobile terminal. The quick-charging method is put forward based on a power adapter with a dynamically adjustable output voltage. According to the method, according to the change of the battery cell voltage in the charging process, a corresponding target charging voltage value is calculated, the volt value of a charging voltage output by the power adapter is dynamically adjusted, and therefore the charging voltage can follow the change of the battery cell voltage in real time to provide a basically stable large current charging for the mobile terminal. The charging current output by the power adapter is directly transferred to a battery to directly charge the battery, since the charging current is improved by a large margin, the charging speed of the battery can be improved, the time needed by single-pass charging of the mobile terminal is shortened, therefore, the influence, on the daily use of users, caused by the fact that the mobile terminal needs to be charged frequently and charged for a long time is reduced, and the satisfaction of the use of the users is improved to a large extent.

Description

technical field [0001] The invention belongs to the technical field of DC charging, and in particular relates to a method for fast charging a battery inside a mobile terminal and a mobile terminal designed based on the charging method. Background technique [0002] At present, portable mobile terminals have penetrated into every aspect of people's lives and become the leading force leading the progress of the semiconductor industry. Most of the current portable mobile terminals use rechargeable batteries to power the internal system circuits of the products. As portable products support more and more functions, the power consumption of their system circuits also increases. In the case of limited battery capacity, the battery life after charging is gradually shortened, resulting in more and more frequent charging operations. . [0003] At present, there are two main battery charging methods widely used: one is to use a conventional power adapter (charger) to charge the batt...
