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 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 uses wireless communication to perform data interaction with the mobile terminal, timely adjusts the volt value of the output charging voltage according to the voltage change of the battery during the charging process, and uses the dynamically changing charging voltage to charge the mobile ...

Abstract

The invention discloses a direct chargeable source adapter, which uses a wireless communication method to carry out regular communication with a mobile terminal as a charging object, so as to obtain the voltage change of the battery inside the mobile terminal, and then according to the change of the battery voltage Dynamically adjust the volt value of the charging voltage output by it, and use the charging voltage to directly charge the built-in battery of the mobile terminal, thereby realizing a substantial increase in the charging current, speeding up the charging speed of the battery, and shortening the battery life of the mobile terminal. The time required for the first charging can reduce the inconvenience caused by the frequent and long-term charging of the mobile terminal to the user's daily use, and greatly improve the satisfaction of the user.

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...
