Embodiment Construction

[0033] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0034] When the present invention uses a conventional power adapter for charging a mobile terminal with a built-in rechargeable battery, 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 depletion. A direct charging source adapter with dynamically adjustable output voltage is proposed. The direct charging source adapter preferably uses UART (Universal Serial Asynchronous Transceiving) communication mode to exchange data with the mobile terminal, and adjusts the volt value of the charging voltage outputted by the battery according to the voltage change of the battery during the charging process. The dynamically changing chargin...

Abstract

The invention discloses a power supply adapter capable of charging directly, which comprises a charging interface, an AC-DC conversion unit and a control unit. The power supply adapter capable of charging directly performs timing communication with a mobile terminal acting as a charging object so as to acquire voltage variations of a battery inside an electronic product, then dynamically adjusts charging voltage outputted by the power supply adapter according to the voltage variations of the battery, and carries out direct charging on the built-in battery of the electronic product by using the charging voltage, thereby realizing great improvement in charging current, accelerating the charging speed of the battery, and shortening the time required by one-time charging of the electronic product. Therefore, inconvenience brought about by frequent and long-time charging of the electronic product for daily use of users can be reduced, and the satisfaction degree of the users in use is improved to a great extent.

Description

Technical field [0001] The invention belongs to the technical field of direct current charging, and specifically 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 all aspects of people's lives and have become the dominant force leading the advancement of the semiconductor industry. Moreover, with the continuous advancement of technology, the types of portable electronic products are also increasing, such as MP3, MP4, PMP, MID, mobile TV terminals, tablet computers, etc., which can not only provide audio, video playback and other entertainment functions, but also provide Various service functions such as navigation, Internet, business, and disease diagnosis greatly facilitate people's lives. [0003] In order to achieve the purpose of portability, for such portable electronic products, rechargeable batteries are arranged inside the product...
