In one embodiment, each first device may be of the same type but may have different power parameters, such that the wireless charger 501 may provide power transfer services for different types or parameters of devices simultaneously.
In the related art, the wireless charger can only provide electric energy for one device to be charged when being connected to the external power supply, and in the embodiment of the application, when the electric energy transmission device receives the electric energy provided by the external power supply, the electric energy transmission device can provide the electric energy for at least two first devices, so that the electric energy providing capability of the wireless charger is enhanced, and the charging function of the wireless charger is more flexible.

In one embodiment, the operation of acquiring the input power of each first device performed by the power transmission device may be performed synchronously or sequentially.
Step B2, establishing at least one first path corresponding to the at least one first device if the first power matches the second power of the at least one first device.
In the embodiment of the present application, if the first power does not match the second power of the at least one first device, the power transmission device may not establish the at least one first path, and may further output a prompt message to prompt the user that the power does not match.
In this embodiment, if the first power does not match the second power of the at least one first device, the power transmission device may further adjust the first power according to the second power, so that the first power matches the second power.
In the embodiment of the present application, in the case that the first power is matched with the second power of the at least two first devices, the controlling the power transmission device to transmit the power to the first device through the first path may be implemented through steps C1 to C2:

The power transmission device sends a request for acquiring the working state information to each first device, each first device writes the respective working state information into a specified byte of the byte stream after receiving the request, and the power transmission device can acquire the working state information of each first device from the specified byte. It should be noted that the byte stream may be filled according to a communication protocol between the power transmission device and each first device, and may specify an offset position of the bytes and a number of the bytes, or may be agreed according to the communication protocol; for example, the offset location and number of bytes specified may be adjusted for different types of first devices.
In one embodiment, determining the power distribution information according to the operating status information of each first device and each second power may be implemented by:
and acquiring the working state information and the corresponding relation between the power information and the electric energy distribution information, and determining the electric energy distribution information according to the working state information of each first device, each second power information and the matching result of the corresponding relation.
