DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0019] In the following introduction, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application. Different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Therefore, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though the embodiment may not be clearly described in the following text.

[0020] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements described without departing from the scope of the present application. Various examples may appropriately omit, replace, or add various processes or components. For example, the described method may be performed in an order different from the order described, and various steps may be added, omitted, or combined. In addition, features described in some examples may be combined in other examples.

[0021] See Figure 4 , Figure 4 The figure is a schematic diagram of the architecture of a battery pack encoding system provided in an embodiment of the present application. In this embodiment of the present application, the system includes multiple battery packs, each of which is equipped with an MCU. The MCUs are connected to each other via a Controller Area Network (CAN) bus, thereby enabling communication between the battery packs via the CAN bus.

[0022] See Figure 1 , Figure 1 : is a flow chart of a battery pack encoding method provided in an embodiment of the present application. In an embodiment of the present application, the method includes: S101, obtaining the coding address and identification information uploaded by each battery pack, and determining coding conflict based on the coding address uploaded by each battery pack; S102 : When a coding conflict occurs, adjust the coding address of each battery pack based on the identification information, and execute S101 until the coding addresses uploaded by each battery pack are different.

[0023] The execution entity of this application may be a cloud server, which may communicate with the MCU unit of each battery pack to obtain or adjust the coding address and identification information of each battery pack.

[0024] In the embodiment of this specification, each battery pack periodically broadcasts its coding address and identification information via the CAN bus. After receiving the coding address and identification information, the cloud server compares the coding addresses uploaded by each battery pack. If the coding address uploaded by a battery pack is identical to the coding addresses uploaded by other battery packs, a coding address conflict is determined. When a coding conflict occurs, the cloud server adjusts the coding address of the battery pack with the coding conflict based on the identification information of the battery pack with the coding conflict. The process then continues with step S101 until all battery packs have uploaded different coding addresses, completing the battery pack coding for the entire power supply system. Compared to the prior art, which requires a DI (Digital Input) detection circuit and a DO (Digital Output) detection circuit to generate two electrical signals, DI (digital input) and DO (digital output), for battery pack coding, this application utilizes a CAN bus for communication, and battery pack coding is adjusted based on the CAN bus. This reduces wiring in the power supply system and reduces the production cost of the entire battery pack power supply system.

[0025] Specifically, the identification information may be a unique ID of each battery pack, that is, a serial number written into the battery pack when the battery pack is produced. The coded address and the identification information may be composed of numbers and letters.

[0026] In one embodiment, adjusting the coding address of each battery pack based on the identification information when a coding conflict occurs includes: determining the battery pack to be adjusted based on the size relationship of the identification information, and adjusting the coding address of the battery pack to be adjusted based on a set adjustment step.

[0027] In an embodiment of the present specification, upon detecting that some battery packs have uploaded the same coding addresses, the cloud server will compare the identification information of the battery packs with coding conflicts to determine the battery pack to be adjusted, set an adjustment step, and adjust the battery pack to be adjusted according to the set adjustment step. For example, if the coding addresses uploaded by battery packs 1, 2, and 3 are the same, all 0111, and the adjustment step is 1, the cloud server will determine that battery packs 2 and 3 are the battery packs to be adjusted based on the identification information of battery packs 1, 2, and 3, and will adjust the coding addresses of battery packs 2 and 3 to 0112. By determining which battery packs have the coding addresses of the battery packs to be adjusted based on the identification information of each battery pack, it is ensured that when a coding address conflict occurs, only one battery pack's coding address remains unchanged, thereby gradually adjusting the coding addresses of each battery pack to be different, thereby distinguishing each battery pack in the power supply system and ensuring stable power supply of the battery packs.

[0028] In one possible implementation, determining the battery pack to be adjusted based on the magnitude relationship of the identification information includes: keeping the coding address of the battery pack with the smallest identification information unchanged, and setting other battery packs with coding conflicts as battery packs to be adjusted.

[0029] In an embodiment of the present specification, the cloud server compares the identification information of battery packs experiencing coding conflicts to determine the battery pack to be adjusted. The process is as follows: the cloud server obtains the identification information of the battery packs experiencing coding conflicts, compares the size of the coding information of each battery pack, maintains the coding address of the battery pack with the smallest identification information unchanged, and sets the coding addresses of the other battery packs experiencing coding conflicts as the battery packs to be adjusted. By maintaining the coding address of the battery pack with the smallest identification information unchanged and adjusting the coding addresses of the other battery packs experiencing coding conflicts, the coding addresses of the battery packs with determined coding addresses are associated with the identification information. When a new battery pack is connected to the system, the coding address of the newly connected battery pack can be determined based on the association between the coding address and the identification information, thereby shortening the coding address conflict determination time and the coding address adjustment time, thereby improving the battery pack coding efficiency.

[0030] In one embodiment, a mapping relationship between the coding address of the battery pack that determines the coding address and the identification information is established. After the newly connected battery pack is powered on, the coding address of the newly connected battery pack is determined based on the coding address of the newly connected battery pack and the mapping relationship.

[0031] In the embodiments of this specification, the coding address and identification information of each battery pack with a determined coding address are obtained, and then a mapping relationship between the coding address and the identification information of the battery pack is established. After the newly connected battery pack is powered on, the identification information of the newly connected battery pack is obtained, and the coding address of the newly connected battery pack is determined based on the identification information and the mapping relationship of the newly connected battery pack. In this application, by establishing a mapping relationship between the coding address and the identification information, and then determining the coding address of the newly connected battery pack based on the identification information and the mapping relationship of the newly connected battery pack, the time for determining coding address conflicts and the coding address adjustment is shortened, thereby improving the efficiency of battery pack coding.

[0032] In one embodiment, the CAN bus is a differential bus.

[0033] In the embodiments of this specification, the CAN bus has advantages such as high anti-interference performance through differential signal transmission, long transmission distance, low bit error rate, and strong fault detection capability.

[0034] In one possible implementation, after the newly connected battery pack is powered on, the coding address of the newly connected battery pack is set to a set default address.

[0035] In the embodiment of this specification, a default address is set. After the newly connected battery pack is powered on, the coding address of the newly connected battery pack is set as the default address.

[0036] In one possible implementation, the default address is: at the end of a set cycle, the coded address corresponding to the battery pack with the largest identification information is selected as the default address.

[0037] If the value of the default address is set too small, as the number of battery packs connected to the power supply system gradually increases, the adjustment time of the coding address of the battery pack connected later will gradually increase. In order to save the adjustment time of the battery pack coding address, in the embodiment of this specification, a cycle period is set. At the end of each cycle period, the coding address and identification information of all battery packs are obtained, and the coding address corresponding to the battery pack with the largest identification information is selected as the default address.
