Embodiment Construction

[0033] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] 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, for the modified hardware circuit, a software program is designed to send the real-time change of the cell voltage of the battery to the direct charging source adapter during the charging ...

Abstract

The invention discloses a fast charging method, a mobile terminal and a direct charging source adapter. It is proposed based on a power adapter with a dynamically adjustable output voltage. The constant current charging method dynamically adjusts the volt value of the charging voltage output by the power adapter according to the range of the cell voltage of the internal battery of the mobile terminal during the charging process, and uses the charging voltage output by the power adapter to directly charge the battery. Through direct charging, the charging current can be greatly increased, which in turn speeds up the charging speed of the battery, shortens the time required for a single charging of the mobile terminal, and reduces the inconvenience caused by the frequent and long-term charging of the mobile terminal for the user's daily use. Influence, to a large extent, improve user satisfaction.

Description

technical field [0001] The invention belongs to the technical field of DC charging, and in particular relates to a method for quickly charging a battery inside a mobile terminal by using a power adapter, and a mobile terminal and a power adapter 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 conven...
