However, the previous generation of communication modes has many defects and cannot meet the new requirements. Therefore, the new generation of products faces the difficult choice of whether to support the previous generation of products. If a new communication mode is directly used, the compatibility between the new and old products cannot be realized. For example, the new battery communication mode is B, and the old battery communication mode is A.

[0048] In addition, it should be further noted that the term "comprising", "containing" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such a process, method, article or device.

[0049] Referring to Figure 1 and Figure 2 A communication interaction method is provided for the communication interaction between the power consumption unit 1 and the power supply unit 2, and specifically, the communication interaction method comprises the following steps:

[0051] The power supply unit 1 sends first identification information to the power consumption unit 2 through the communication module 3;

[0052] The power consumption unit 2 parses the first identification information through the communication module 1; and

[0053] The communication module 3 matches and calls the serial communication protocol applicable to both the power supply unit 1 and the power consumption unit 2 on the basis of the communication structure it has itself, to establish communication between the power consumption unit 1 and the power supply unit 2.

[0054] Further, the communication interaction method further comprises that the power consumption unit 2 replies second identification information to the power supply unit 1 through the communication module 3 according to the first identification information parsed by the communication module 3, and parses via the communication module 3.

[0056] Further, the power supply unit 1 and the power consumption unit 2 in the application are relative to the power supply and power consumption appliances, specifically, in the field of garden machinery, if the power supply unit 1 is a battery pack, the power consumption unit 2 can be a garden tool powered by the battery pack and working, such as a mower, a snow blower, a chain saw, etc.; and when the power supply unit 1 is a charger, the power consumption unit 2 can be a charged battery pack or a rechargeable garden tool, that is, in the application, the specific selection of the power supply unit 1 and the power consumption unit 2 in the communication interaction system 200 can be selected according to actual needs, which is not limited herein.

[0057] Specifically, the communication interaction method of the application is mainly applied to the starting stage of the communication establishment between the power supply unit 1 and the power consumption unit 2, that is, at least one of the power supply unit 1 and the power consumption unit 2 initiates a communication request (in the application, the power supply unit 1 initiates a request as an example) at the starting stage of the communication establishment, and the other party (in the application, the power consumption unit 2 is taken as an example) sends corresponding communication information to reply after receiving the parsed data, and finally the power supply unit 1 continues to send the next frame of data, and the communication establishment between the power supply unit 1 and the power consumption unit 2 ends.

[0058] Further, the communication module 3 is used to provide a communication interface between the power supply unit 1 and the power consumption unit 2, including a hardware circuit, a connection terminal, and a power supply circuit and a communication circuit integrated on the hardware circuit; further, the communication module 3 is integrated with a plurality of serial communication protocols and communication modes, so that the communication module 3 can match and call the serial communication protocols and communication modes suitable for the power supply unit 1 and the power consumption unit 2 on the basis of the communication structure it has, to establish communication between the power supply unit 1 and the power consumption unit 2.

[0059] Specifically, the power supply unit 1 sends first identification information to the power consumption unit 2 through the communication module 3, and the power consumption unit 2 parses the first identification information through the communication module 3 and transmits second identification information to the power supply unit 1, wherein the communication module 3 can also parse the first identification information and the second identification information at the same time or separately; and in the application, the first identification information and the second identification information each contain at least two groups of identification bytes, and at least one group of identification bytes in the two groups of identification bytes carries serial communication protocol information of the power supply unit and the power consumption unit.

[0061] Further, the communication module 3 can also match the communication mode suitable for the power supply unit 1 and the power consumption unit 2 through the first identification information and the second identification information, in the present application, the communication mode is affected by the model of the power supply unit 1 and the power consumption unit 2, and the communication mode at least includes the structure of the communication line between the power supply unit 1 and the power consumption unit 2.

[0063] Preferably, the communication mode for establishing the communication channel between the power supply unit 1 and the power consumption unit 2 comprises one or several of UART, 1-WIRE, CAN, and IIC data bus, i.e. in the present application, the communication module 3 can select the communication line matching the serial communication protocol as the communication mode between the power supply unit 1 and the power consumption unit 2 on the basis of analyzing and selecting the corresponding serial communication protocol, and the communication between the power supply unit 1 and the power consumption unit 2 is stable.

Since the new serial communication protocol used by the power supply unit 1 is downward compatible with the old serial communication protocol used by the power-on unit 2, the communication module 3 matches the old serial communication protocol of the power supply unit 1 and the power-on unit 2 and the communication line compatible with the last-generation power-on unit, further receives the next frame of communication data sent by the power supply unit 1, and then enters the old serial communication stage, and completes the communication establishment between the power supply unit 1 and the power-on unit 2.
