Dual channel charging method, system and terminal thereof

Abstract

The invention provides a dual channel charging method, a system and a terminal thereof. In the method, when a processor receives a current wired charging state and a current wireless charging state, according to a charging current allowed by a current cell and a Joule law, currents needed by wired and wireless dual channels are calculated respectively, charging current and charging voltage configurations are performed on a first power supply management chip and a second power supply management chip respectively so that the first power supply management chip and the second power supply management chip charge the cell based on the configurations. In embodiments of the invention, two completely isolated charging channels are used, which are one wired charging channel and one wireless charging channel; under the condition that wired and wireless charging are simultaneously performed, simultaneously, a whole charging process is ensured to be safe; a load loss of each charging channel is reduced and charging heating is reduced so that purposes of increasing charging efficiency, shortening charging time and increasing a user experience are reached.

Description

technical field [0001] The present invention relates to the technical field of electronic circuits, in particular to a dual-channel charging method, system and terminal. Background technique [0002] With the continuous development of science and technology, various portable devices or handheld devices are more and more widely used in people's lives. During the use, they mainly rely on rechargeable batteries to provide them with the necessary power. [0003] In the prior art, there are wireless charging and wired charging methods. Most of the devices now use wired charging, and there are also wired charging as the main method and wireless charging as the auxiliary method. For wired charging as the main method and wireless charging as the auxiliary method, the charging process is generally as follows. When the two charging methods are involved at the same time, the wired charging is first selected, and the wireless charging is disconnected at the same time. [0004] The meth...

Problems solved by technology

[0004] The methods in the prior art cannot maximize the charging efficiency, that is, maximize the efficiency of wireless charging, and cannot charge a large amount of power in the shortest time. If wired charging or wireless charging is used for single charging for high-current charging, It will cause excessive charging current or voltage, resulting in efficiency loss and excessive heat generation on the charging path, affecting user experience
