[0035] Figure 1 A flowchart of a method for numbering slave boards in a battery management system provided in an embodiment of the present application;

[0036] Figure 2 This is a structural diagram of a slave board numbering device of a battery management system provided in an embodiment of the present application. DETAILED DESCRIPTION

[0037] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0038] The following describes a method, device, and electronic device for numbering slave boards in a battery management system according to embodiments of the present application with reference to the accompanying drawings.

[0039] Figure 1This is a flow chart of slave board numbering in a battery management system provided by an embodiment of the present application. Figure 1 As shown, the slave board numbering method of the battery management system includes the following steps:

[0040] S101 , powering on the i-th slave board, and the i-th slave board determines whether first serial number information is received.

[0041] The first numbering information is sent to the intranet by a slave board other than the i-th slave board. There is at least one first numbering information; i∈[1,N], where N is the total number of slave boards. This ensures that each slave board is numbered according to the above logic.

[0042] In an embodiment of the present application, when numbering the slave boards of the battery management system, for a certain slave board, for example, the i-th slave board, the i-th slave board can be powered on first to start working and enter the automatic numbering mode. Then, it can be determined whether the i-th slave board has received numbering information sent by other slave boards from the intranet, that is, the first numbering information. These first numbering signals can be sent by the numbered slave boards other than the i-th slave board in the battery management system, and the first numbering information should include at least one slave board number. For example, assuming i=3, the first numbering information can include the number 1 of the first slave board that has been numbered and the number 2 of the second slave board that has been numbered.

[0043] S102, when the first numbering information is received, the number of the i-th slave board is set to the sum of the difference between the maximum number in the first numbering information and the set number, and the sum of the difference between the maximum number in the first numbering information and the set number is sent to the intranet.

[0044] In an embodiment of the present application, if the i-th slave board receives first numbering information, the maximum number can be found from the received first numbering information, and then the maximum number can be added to a set number difference (i.e., the set difference between the numbers of any two adjacent slave boards, such as 1) to obtain the number of the i-th slave board. The sum of the maximum number and the set number difference can be set as the number of the i-th slave board. Then, the number of the i-th slave board can be sent to the intranet to make other slave boards aware of it.

[0045] S103: If the first numbering information is not received, the number of the i-th slave board is set to a preset starting number, and the preset starting number is sent to the intranet.

[0046] In an embodiment of the present application, if the i-th slave board does not receive the first numbering information, it can be assumed that there are no other slave boards numbered before this in the current numbering, and the i-th slave board is the first slave board in the current numbering. In this case, the number of the i-th slave board can be set to a preset starting number. The preset starting number can be set to a value such as 1 or 0. It can be understood that i∈[1,N], where N is the total number of slave boards. This ensures that each slave board is numbered according to the above logic.

[0047] In an embodiment of the present application, by powering on the i-th slave board, the i-th slave board determines whether it has received first numbering information; wherein the first numbering information is sent to the intranet by a slave board other than the i-th slave board, and the first numbering information is at least one; i∈[1,N], where N is the total number of slave boards; if the first numbering information is received, the number of the i-th slave board is set to the sum of the difference between the maximum number in the first numbering information and the set number, and the sum of the difference between the maximum number in the first numbering information and the set number is sent to the intranet; if the first numbering information is not received, the number of the i-th slave board is set to a preset starting number, and the preset starting number is sent to the intranet. In this way, dynamic numbering of slave boards can be achieved through the interaction of numbering information between slave boards; when receiving numbering information from other slave boards, the slave board determines its own number by calculating the sum of the maximum number and the set difference, thereby avoiding numbering conflicts and ensuring numbering continuity; if no numbering information is received, the preset starting number is used, thereby ensuring that the slave board can quickly enter the working state. In this way, the flexibility and reliability of slave board numbering can be improved, the system initialization process can be simplified, the scalability of the system can be enhanced, and the efficiency and accuracy of slave board numbering can be improved.

[0048] In one possible implementation, when the first numbering information is received, the number of the i-th slave board is set to the sum of the difference between the maximum number in the first numbering information and the set number, and the sum of the difference between the maximum number and the set number is sent to the intranet; or, when the first numbering information is not received, the number of the i-th slave board is set to a preset starting number, and the preset starting number is sent to the intranet, and then the method further includes:

[0049] The (i+1)th slave board is powered on, and the (i+1)th slave board determines whether the second number information is received;

[0050] When the i+1th slave board receives the second numbering information, the number of the i+1th slave board is set to the sum of the difference between the maximum number in the second numbering information and the set number, and the sum of the difference between the maximum number in the second numbering information and the set number is sent to the intranet.

[0051] In an embodiment of the present application, after the i-th slave board is numbered, the i+1-th slave board can be numbered. Exemplarily, the i+1-th slave board can be powered on to enter the automatic numbering mode. The i+1-th slave board can check whether it has received the numbering information sent by other slave boards, that is, the second numbering information. Similarly, the second numbering information can also have at least one number, which is sent by the numbered slave board before the i+1-th slave board. If the i+1-th slave board receives the second numbering information, the maximum number can be found from the second numbering information, added to the set number difference, and the number of the i+1-th slave board is obtained and set as the number of the i+1-th slave board, and the number is sent to the intranet. In this way, by dynamically allocating numbers to slave boards one by one, efficient initialization and number management of the slave boards can be achieved; after power-on, each slave board will dynamically generate its own number based on the existing numbering information to avoid number conflicts while ensuring the continuity and uniqueness of the numbers; by processing the numbers of each slave board one by one, the system can flexibly cope with the access of different numbers of slave boards, enhancing the scalability and adaptability of the system; in addition, this method also simplifies the system initialization process, reduces manual intervention, and improves the system's degree of automation and operating efficiency.

[0052] In a possible implementation, the method further includes:

[0053] For the Nth slave board, the number of the Nth slave board is set to N, and the number N of the Nth slave board is sent to the intranet.

[0054] In an embodiment of the present application, for the Nth slave board, that is, the last slave board, the Nth slave board is powered on and enters the automatic numbering mode. Since the Nth slave board is the last slave board, its number can be directly set to N. And, the number N of the Nth slave board is sent to the intranet. It can be understood that since the number of battery modules for each project is known, the number of slave boards in the intranet is also known, and each slave board knows the maximum number. When the last slave board completes the automatic numbering, it will simultaneously send its own number to the intranet, that is, the maximum number of the slave boards in the intranet.

[0055] In a possible implementation, for the Nth slave board, after setting the number of the Nth slave board to N and sending the number N of the Nth slave board to the intranet, the method further includes:

[0056] Switch the working mode of all slave boards in the intranet to working mode.

[0057] In an embodiment of the present application, when all slave boards receive a signal from the highest-numbered slave board, the operating mode of all slave boards in the intranet switches from automatic numbering mode to normal operating mode. For example, a unified command or signal can be sent to the intranet to notify all slave boards to switch to working mode. After receiving the switching command, the slave boards complete the internal state transition and enter normal operating mode. In this way, through dynamic number allocation and working mode switching, efficient slave board initialization and system operation management can be achieved.

[0058] In a possible implementation, when the i-th slave board is powered on, the i-th slave board determines whether the first numbering information is received, including:

[0059] Power on the i-th block from the board;

[0060] The i-th slave board determines whether the first numbered information is received within a set time period;

[0061] Send the sum of the difference between the maximum number and the set number to the intranet, including:

[0062] According to the preset period, the sum of the difference between the maximum number and the set number is sent to the intranet;

[0063] Send the preset starting number to the intranet, including:

[0064] According to the preset period, the intranet sends the preset starting number.

[0065] In an embodiment of the present application, after the i-th slave board is powered on, timing can be started. Within the set duration, it is checked whether the number information (which can be the first number information) sent by other slave boards is received. The set duration can be, for example, 500ms. When sending the sum of the difference between the maximum number and the set number to the intranet, the sum of the difference between the maximum number and the set number can be sent to the intranet according to a preset period, for example, the preset period can be 10ms. A preset starting number can also be sent to the intranet according to a preset period.

[0066] In a further possible implementation, the set number difference may be 1; the intranet may be a CAN bus (CANBus) or a wireless communication network.

[0067] To make the method provided in the embodiments of the present application clearer, the following is an explanation with reference to specific examples.

[0068] The slave board numbering method provided in the embodiments of the present application applies the concept of closed-loop networking. By powering on the slave boards one by one, the slave boards are automatically numbered. The first slave board powered on will automatically start numbering at 1, and the slave boards powered on later will automatically be numbered 2, 3, 4, 5, 6, 7, 8, and so on. When the numbering of the last slave board is completed, the working mode of all slave boards is switched from automatic numbering mode to normal working mode.

[0069] Specifically: the slave boards can be powered on in sequence. The first slave board enters the automatic numbering mode after power-on. If it does not receive the number sent by other slave boards within 500ms (taking a 500ms time constant as an example), it will automatically number itself 1, and then send the number 1 to the intranet (CAN bus or wireless communication) with a period of 10ms; the second slave board enters the automatic numbering mode after power-on. If it receives the number 1 sent by the first slave board within 500ms, it will number itself 2 after 500ms, and at the same time send the number 2 to the intranet (CAN bus or wireless communication) with a period of 10ms; the third slave board enters the automatic numbering mode after power-on. If it receives the number 1 sent by the first slave board and the number 2 sent by the second slave board within 500ms, it will number itself 3 after 500ms, and at the same time send the number 3 to the intranet (CAN bus or wireless communication) with a period of 10ms. By analogy, each module enters the automatic numbering mode after powering on the board. The maximum number received within 500ms plus 1 is its own number.

[0070] Because the number of battery modules in each project is known, the number of slave boards on the intranet (CAN bus or wireless communication) is also known, and each slave board knows its maximum number. When the last slave board completes automatic numbering, it simultaneously sends its own number, the maximum number of slave boards on the intranet, to the CAN bus or wireless communication network in a 10ms cycle. When other slave boards receive the maximum number, all slave boards on that intranet (CAN bus or wireless communication) switch from automatic numbering mode to normal operation.

[0071] In this way, there is no need to manually map the slave board number and the installation position of the battery module. By applying the idea of ​​closed-loop networking, all slave boards in the intranet (CAN bus or wireless communication) can be automatically numbered by powering on the slave boards in sequence. In actual use, all slave boards can be powered on in sequence according to the serial number of the battery module installation position. According to this method, the serial number of the battery module installation position is the value of the automatic numbering of all slave boards. After completing the automatic numbering step, all slave boards can be powered on at the same time the next time they are used. At this time, after each slave board is powered on, it will receive the signal from the slave board with the largest number within 500ms, and all slave boards will directly enter the normal working mode. In this way, the process steps of slave board numbering can be reduced, and the cost of slave board numbering can be reduced. Provide numbering efficiency and accuracy.
