In addition, the embodiments and features in the embodiments of the present application may be combined with each other if there is no conflict.

[0044] A wireless BMS address allocation method provided in an embodiment of the present application is applied to Figure 1 In the application scenario shown, the configuration terminal is used to allocate addresses for the wireless BMS, wherein the wireless BMS, namely the wireless battery management system (WBMS), is a battery management system that uses wireless communication technology for signal transmission. In the actual application scenario, the wireless BMS mainly includes a wireless module, a main device and multiple sub-devices, and the configuration terminal mainly includes a wireless sensor, an image sensor and an operation interface, wherein the image sensor can specifically use a camera, and the operation interface can generally be understood as a user operation interface that can be used to implement address acquisition and address allocation functions. The configuration terminal can obtain the device address assigned to each sub-device by the wireless BMS after self-networking through the wireless sensor, and according to the user's operation on the operation interface, use the image sensor to obtain the image of the wireless BMS, and determine the device address pre-assigned to each sub-device based on the image, and send the device address of the specific sub-device that needs to be corrected to the wireless BMS through comparison, so that the wireless BMS only needs to update the device address of the specific sub-device without rewriting the device address configuration in the entire BMS. Compared with the existing one-to-one allocation scheme of using handheld devices to allocate device addresses to BMS, it can significantly improve the configuration speed and efficiency, and realize more flexible and efficient networking address allocation, especially to meet the application requirements of BMS address allocation on mobile devices and in dynamic environments.

[0045] See also Figure 2 , which is a wireless BMS address allocation method provided by the present application, which can be applied to a configuration terminal and a wireless BMS, wherein the wireless BMS includes a plurality of sub-devices. In the present method embodiment, the configuration terminal is used as the execution subject for introduction. The method is as follows Figure 2 The steps shown mainly include the following steps S11 to S14.

[0046] Step S11: After the configuration terminal is connected to the wireless BMS, the first device address of each sub-device in the wireless BMS is automatically obtained;

[0047] Specifically in this embodiment, the first device address specifically refers to the device address assigned to each sub-device by the wireless BMS system after self-networking, wherein the wireless BMS assigns device addresses to each sub-device after the system self-networking, and a preferred implementation is to assign device addresses to each sub-device according to the wireless signal strength of each sub-device. It is understandable that the wireless BMS may also assign addresses to each sub-device in other ways, for example, assigning a custom device address to each sub-device in turn according to a pre-stored address list.

[0048] In this embodiment, after the configuration terminal is connected to the wireless BMS, it may specifically send a request to the wireless BMS through wireless communication to obtain the first device address of each sub-device in the wireless BMS.

[0049] Step S12: configuring the terminal to collect and acquire an image of the wireless BMS, determining location information of each sub-device in the wireless BMS based on the image, and determining a second device address of each sub-device according to the location information;

[0050] Specifically in this embodiment, the configuration terminal may be configured with a camera, and the configuration terminal acquires the image of the wireless BMS through the camera.

[0051] In one embodiment, the determining the location information of each sub-device in the wireless BMS based on the image may specifically include: using a Sobel operator (Sobel operator) to perform edge detection on the image to determine the location information of each sub-device in the wireless BMS. The process of using the Sobel operator for edge detection in this embodiment may be specifically as follows: first, grayscale the image, match the grayscale image with a pre-set image template to determine the difference area, use the Sobel operator to perform edge calculation on the difference area to binarize the image, and automatically identify the location of each sub-device in the image by comparing the image X and Y coordinates. It can be understood that the pre-set image template may be an image containing the location information of each sub-device in the BMS that is pre-stored in the configuration terminal.

[0052] Step S13: The configuration terminal compares the second device address with the first device address, and determines the sub-device that needs to have its address corrected according to the comparison result;

[0053] Specifically in this embodiment, the configuration terminal compares the first device address and the second device address corresponding to each sub-device. If they are consistent, no correction is required. If they are inconsistent, the sub-device is determined as a sub-device that needs address correction.

[0054] Step S14: the configuration terminal sends an address configuration instruction to the wireless BMS so that the first device address of the sub-device that needs to be corrected is updated to the second device address.

[0055] Specifically in this embodiment, the configuration terminal sends an address configuration instruction to the wireless BMS via wireless communication, and the address configuration instruction includes a device identifier for determining a sub-device and a second device address corresponding to the sub-device.

[0056] See also Figure 3 , which is a wireless BMS address allocation method provided by the present application, which can be applied to the configuration terminal and the wireless BMS, the wireless BMS includes multiple sub-devices, and in this method embodiment, the wireless BMS is used as the execution subject for introduction, the method is as follows Figure 3 The steps shown mainly include the following steps S21 to S22.

[0057] Step S21: After the wireless BMS completes the self-organizing network, the wireless BMS allocates a first device address to each sub-device;

[0058] Specifically in this embodiment, the wireless BMS includes a main device and multiple sub-devices, and this step specifically includes: after the main device of the wireless BMS and the multiple sub-devices complete self-networking, the main device detects and obtains the wireless signal strength of the multiple sub-devices, and assigns a first device address to each sub-device according to the wireless signal strength. For example, the sub-devices of the BMS include battery cell 1, battery cell 2, and battery cell 3. The wireless signal strength of battery cell 1 obtained by detection is -40dbm, the wireless signal strength of battery cell 2 is -45dbm, and the wireless signal strength of battery cell 3 is -50dbm. Then, according to the signal strength, the device address assigned to battery cell 1 is 0x01, the device address assigned to battery cell 2 is 0x02, and the device address assigned to battery cell 3 is 0x03.

[0059] Step S22: When the wireless BMS receives the address configuration instruction sent by the configuration terminal, it determines the sub-device that needs address correction and its corresponding second device address by parsing the address configuration instruction, and updates the first device address of the sub-device that needs address correction to the second device address.

[0060] Specifically in this embodiment, the master device of the wireless BMS parses the address configuration instruction to determine the sub-device that needs to be corrected, and the master device reallocates the address of the sub-device that needs to be corrected to update the address of the sub-device from the first device address to the second device address. For example, the information obtained by the master device of the wireless BMS parsing the address configuration instruction includes: battery cell 1-0x03 and battery cell 3-0x01, then correspondingly, the master device of the wireless BMS updates the device address of battery cell 1 from 0x01 to 0x03, and updates the device address of battery cell 3 from 0x03 to 0x01.

[0061] In a specific implementation manner, a wireless BMS address allocation method provided by the present application is applied to a configuration terminal and a wireless BMS, wherein the wireless BMS includes a plurality of sub-devices. Figure 4 The steps shown mainly include the following steps 101 to 109 .

[0062] Step 101: The wireless BMS completes the self-organizing network and allocates a first device address to each sub-device;

[0063] Step 102: Power on the configuration terminal and establish a wireless connection with the wireless BMS;

[0064] Step 103: The configuration terminal sends a command to obtain a device address to the wireless BMS;

[0065] Step 104: The wireless BMS returns the first device address of each sub-device to the configuration terminal;

[0066] Step 105: The configuration terminal determines a second device address pre-assigned to each sub-device based on the collected image of the wireless BMS;

[0067] Step 106: The configuration terminal compares the first device address and the second device address corresponding to each sub-device, and determines the sub-device that needs to be corrected according to the comparison result;

[0068] Step 107: The configuration terminal sends an address configuration instruction to the wireless BMS;

[0069] Step 108: The wireless BMS parses the address configuration instruction to determine the sub-device that needs to be corrected and the second device address corresponding thereto, and updates the first device address of the sub-device that needs to be corrected to the second device address;

[0070] Step 109: The wireless BMS returns an address configuration response to the configuration terminal, and the process ends.
