Problems solved by technology

[0004] However, when the master device receives power and supplies power at the same time, because the power supply power is independently agreed between the master device and the slave device, and the charging power is independently agreed between the master device and the charger, therefore, it is impossible to guarantee that the charging power of the charger can meet multiple requirements at the same time. slave device requirements

Embodiment 1

[0044] An embodiment of the present invention provides a charging method based on multiple USB-C interfaces, see image 3 , is a schematic flowchart of Embodiment 1 provided by the embodiment of the present invention.

[0045] In step S101, the required voltage and required current of each slave device connected to the USB-C interface, and the maximum supply current of the charger are acquired.

[0046] The Type-C module at the USB-C interface of the master device performs CC communication with the Type-C module at the interface of the slave device, and each interface establishes CC communication with the slave device to obtain the required voltage and current of all slave devices. At the same time, the master device establishes CC communication with the charger to obtain the maximum supply current of the charger.

[0047] In step S102, according to the required voltage of the slave device and the required voltage of the master device, the power supply voltage of the charger an...

Embodiment 2

[0070] see Figure 7 , is a schematic flow chart of Embodiment 2 of the present invention.

[0071] In step S201, the required voltage and required current of each slave device connected to the USB-C interface, and the maximum supply current of the charger are acquired.

[0072] In step S202, according to the required voltage of the slave device and the required voltage of the master device, the power supply voltage of the charger and the slave devices compatible with the power supply voltage are determined based on the principle that the number of devices supplying power to the slave devices is the largest.

[0073] In step S203, according to the maximum supply current of the charger and the demand current of the slave equipment compatible with the supply voltage, it is judged whether the maximum supply current can meet the current demand of the slave equipment compatible with the supply voltage.

[0074] In step S204, when the maximum supply current cannot meet the current ...

Abstract

The invention relates to a multi-USB-C interface-based charging method and a master device. The method comprises the steps of obtaining needed voltage and needed current of one slave device connected with each USB-C interface, and maximum power supply current of a charger; determining power supply voltage of the charger and the slave device compatible with the power supply voltage according to the needed voltage of the slave devices and the needed voltage of the master device; judging whether the maximum power supply current can meet the current requirement of the slave device compatible with the power supply voltage or not according to the maximum power supply current of the charger and the needed current of the slave device compatible with the power supply voltage; and when the maximum power supply current meets the current requirement, controlling the master device to receive power provided by the charger according to the power supply voltage and the maximum power supply current and simultaneously controlling the master device to carry out power supply according to the power supply voltage and the needed current of the slave device compatible with the power supply voltage. According to the method provided by the embodiment of the invention, the charging requirements of multiple slave devices when the master device is charged are effectively ensured and the power supply capability of the charger is fully utilized.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging method based on multiple USB-C interfaces and a main device. Background technique [0002] The USB Type-C interface, referred to as the USB-C interface, supports non-directional forward and reverse insertion in terms of physical structure, and supports the transmission of data and audio and video signals at the same time in terms of function. At the same time, the USB-C interface supports bidirectional transmission of power, both It can accept the power supply to charge the electronic equipment installed with this interface, and can also provide power to other external electronic equipment, and, based on the latest USB PD (USB Power Delivery,) protocol, the USB-C interface can transmit up to 100W when charging power. [0003] see figure 1 , figure 1 It is a schematic diagram of charging a single USB-C interface device. Such as figure 1 As shown, the main device 1...
