Embodiment Construction

[0030] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0031] In the present invention, when a mobile terminal with a built-in rechargeable battery is charged with a conventional power adapter, since the charging voltage output by the conventional power adapter is constant, the charging current cannot be too high under the control of the power management chip, usually below 1.5A. As a result, it takes a long time for the battery to be fully charged from exhaustion, and a direct charging power adapter with dynamically adjustable output voltage is proposed. The direct charging source adapter preferably adopts UART (Universal Serial Asynchronous Transceiver) communication method to perform data interaction with the mobile terminal, timely adjusts the volt value of its output charging voltage according to the voltage change of the battery during the charging process, and utilizes...

Abstract

The invention discloses a power adapter capable of direct charging. The power adapter adapts an UART communication mode to regularly communicate with a mobile terminal as a charging target, so as to obtain the voltage variation of the battery in the mobile terminal; the volt value of the output charging voltage is dynamically adjusted according to the variation of the battery voltage, the charging voltage directly charges a built-in battery of the mobile terminal, so as to realize the great increase of the charging current, accelerate the charging speed of the battery, and shorten the one-time charging time of the mobile terminal, then the inconvenience on user daily use caused by the long charging time of mobile terminal can be reduced, and the user satisfaction is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of DC charging, and in particular relates to a power adapter for fast charging a battery inside a mobile terminal. Background technique [0002] At present, portable electronic products (or mobile terminals) have penetrated into every aspect of people's lives and become the leading force leading the progress of the semiconductor industry. Moreover, with the continuous advancement of technology, there are more and more types of portable electronic products, such as MP3, MP4, PMP, MID, mobile TV terminals, tablet computers, etc., which can not only provide entertainment functions such as audio and video playback, but also provide Various service functions such as navigation, Internet access, business, and disease diagnosis greatly facilitate people's lives. [0003] In order to achieve the purpose of portability, for such portable electronic products, a rechargeable battery is arranged inside the product, and...
