Embodiment 1

[0043] Such as figure 1 As shown, it is a schematic flow chart of a dual-channel charging method disclosed in Embodiment 1 of the present invention, which mainly includes the following steps:

[0044] Step S101, when the wired charging interface is connected to wired charging, the wired charging interface sends the current wired charging status to the processor;

[0045] Step S102, when the wireless charging interface is connected to wireless charging, the wireless charging interface sends the current wireless charging status to the processor through the wireless charging management chip;

[0046] It should be noted that there is no sequence between steps S101 and S102. Specifically, as long as the wired charging interface is connected to wired charging, and when the wireless charging interface is connected to wireless charging, the current wired and / or In the wireless charging state, even if it is connected to charging at the same time, there is no priority.

[0047] Step S...

Embodiment 2

[0062] Based on the dual-channel charging method disclosed in the first embodiment of the present invention, the second embodiment of the present invention also discloses a dual-channel charging system 100, including: a wired charging channel connected to the battery 101 and the processor 102; a wireless charging channel connected to the battery 101 and the processor 102;

[0063] Wherein, the wired charging channel includes: a wired charging interface 103, a first power management chip 104, and the battery 101 connected in sequence;

[0064] The first power management chip 104 and the wired charging interface 103 communicate with the processor 102 through the baseband 108 at the same time;

[0065] The wired charging interface 103 is configured to send the current wired charging status to the processor 102 when wired charging is connected;

[0066] The wireless charging channel includes: a wireless charging interface 105 connected in sequence, a wireless charging management ...

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...
