Abstract

The invention discloses a fast-charging method, a mobile terminal and a power adapter capable of being charged directly. The fast-charging method is provided based on the power adapter of which output voltage dynamic is adjustable. The voltage of the battery-core of a battery is divided into multiple sections, then a sectional-type constant-current charging way is adopted, the value of the charging voltage output through the power adapter is adjusted dynamically according to the located sections of the battery-core voltage of the battery inside the mobile terminal in the charging process, and the battery is charged directly through the charging voltage output through the power adapter, so that the charging current is improved greatly, thereby the charging speed of the battery is accelerated, the single-time charging time needed by the movable terminal is shortened, the influence of the situation that the mobile terminal needs to be charged frequently for a long time on daily use of a user is lowered, and the customer-using satisfaction degree in promoted 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 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...
