Abstract

The embodiment of the invention discloses a charging control device and method. The charging control device comprises a battery, at least two charging management chips and a controller, wherein the at least two charging management chips are connected in parallel, the input end of each of the at least two charging management chips is used for being connected with a current output end of an adapter, and the output end of each of the at least two charging management chips is connected with the battery and connected with the controller through a bus. The controller is used for acquiring whether the adapter is in an access state and dynamically controls the working state of each of the at least two charging management chips to charge the battery after the fact that the adapter is in the access state is acquired. According to the technical scheme, by connecting a plurality of charging management chips in parallel, the charging management chips are controlled dynamically by the controller, the charging speed can be quickened, the charging time can be shortened, and the charging requirement for quick and large current of the battery on a terminal device can be met.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of charging, and in particular, to a charging control device and method. Background technique [0002] Currently, many terminal devices such as smartphones, tablet computers, and personal digital assistants are powered by batteries. With the rapid development of electronic technology, terminal equipment has more and more functions. For example, people can use terminal equipment for instant messaging, surfing the Internet, playing games, and watching videos. A large amount of power is consumed when using a terminal device. Therefore, the performance requirements for the battery and charging speed of the terminal equipment are also increased. [0003] In the prior art, when using an adapter (that is, a charger) to charge the battery on the terminal device, the current output by the adapter generally passes through the single-channel charging management chip connected to it, and then is ...
