[0042] In order to make the following embodiments clear, the technical terms involved in this application are first introduced.

[0043] BMS is a system dedicated to battery management. Its main purpose is to ensure that the battery works safely and efficiently and to extend the battery life. Battery BMS plays an important role in many applications such as electric vehicles, renewable energy storage systems, and portable electronic devices.

[0044] MCU (Microcontroller Unit) is the core control unit in BMS, responsible for handling tasks such as battery status monitoring, data calculation, and control strategy execution. MCU plays a vital role in battery management. It interacts with various sensors and actuators to ensure the safety, reliability, and efficient operation of the battery.

[0045] Boot (Boot loader) is a key software component in BMS, responsible for hardware initialization and system boot before its operating system starts. The main task of Boot is to load the operating system kernel when the BMS starts and hand over control to the operating system, thereby starting the entire BMS.

[0046] HSM (Hardware Security Module) is a key component used to enhance system security. The application of HSM in BMS mainly focuses on data protection, identity authentication, key management and secure communication to ensure the security and integrity of the battery management system.

[0047] BMU (Battery Management Unit) is the core module of the entire system, responsible for monitoring, managing and protecting the safe and efficient operation of the battery pack. BMU is the key part of the BMS that performs actual management and control. It monitors the battery's voltage, current, temperature and other parameters to achieve battery status assessment, protection strategy execution and system control.

[0048] As described above, for the current fast startup of BMS, in order to ensure the startup safety of BMS, it is often necessary to first verify the accuracy of the code in the APP to which the BMS belongs. Only after the code verification is passed can the BMS be started through the corresponding boot program, and the startup is considered completed when the first frame message sent by the BMS is received.

[0049] However, since the current code verification algorithm is relatively complex and the business processing involved when the BMS sends the first frame message also takes a certain amount of time, it is difficult for the BMS to complete the entire startup process in a short period of time, resulting in a longer time required for its safe startup.

[0050] In order to solve the above problems, the embodiment of the present application provides a BMS startup method, device, BMS and medium. In the method, when responding to the BMS startup instruction to execute the boot program, the code accuracy of the BMS is verified by the preset verification parameters during the execution of the boot program, so as to realize the parallel processing of the boot program execution and the code accuracy verification, thereby effectively reducing the time consumed by the boot program execution and the code verification. Subsequently, after the code verification result for the BMS is verified, the BMS is initialized to send the first frame message to the external interactive terminal through the initialized network configuration. Accordingly, in the process of the BMS performing the network initialization processing, the startup data of the BMS is synchronously collected to provide a data basis for the first frame message that the BMS needs to send. In this way, when the BMS completes the initialization processing for the network, it can immediately send its own startup message to the external interactive terminal according to the corresponding startup data and network configuration. The various transactions that the BMS needs to process at startup are processed in parallel, which saves the startup time of the BMS to the greatest extent and optimizes the startup speed of the BMS.

[0051] Next, the BMS startup method provided in the embodiment of the present application will be introduced in conjunction with the specific embodiment drawings. Figure 1 , Figure 1 A schematic diagram of the startup process of a BMS in an actual application scenario provided in an embodiment of the present application. Figure 1 The BMS startup process diagram shown includes the hardware units that need to be involved in the BMS startup process, namely the HSM-Core, BMU-Core0 and BMU-Core1 in the figure.

[0052] Among them, HSM-Core is used to perform specific code accuracy verification work, BMU-Core0 is used to execute specific boot programs and subsequent network initialization processing, and BMU-Core1 is used to collect BMS startup data. Figure 1 It can be seen that when the three are processing their respective tasks, other tasks are also being processed in parallel, thereby minimizing the startup time of the BMS and optimizing the startup speed of the BMS.

[0053] exist Figure 1 See further on Figure 2 , which is a flow chart of a BMS startup method provided in an embodiment of the present application, specifically comprising the following steps:

[0054] S101: Responding to a BMS startup instruction to execute a startup boot program of the BMS, and during the execution of the startup boot program, verifying the accuracy of a code of the BMS according to preset verification parameters for the BMS to obtain a code verification result; the startup instruction of the BMS is determined based on an external interactive terminal.

[0055] First, after the BMS is powered on, the BMU-Core0 in the BMS responds to the BMS startup instruction, thereby executing the BMS boot program. Before the boot program is executed, the HSM-Core will continue to wait for instructions to execute code correctness verification. When BMU-Core0 starts to execute the boot program, BMU-Core0 immediately sends a request for code accuracy verification to the HSM, so that the HSM-Core immediately starts calculating the MAC value of the APP to which the BMS belongs, and the HSM-Core verifies the BMS code accuracy through the real-time calculated MAC value and the preset verification parameters for the BMS. Among them, the preset verification parameters are used to characterize the parameters that need to be applied when verifying the code accuracy of the BMS. The specific content of the preset verification parameters will be described and explained below.

[0056] It is understandable that in actual application scenarios, the code accuracy verification process often takes a long time due to the complexity of the verification algorithm. By processing the code accuracy verification work in parallel during the execution of the boot program, the time occupied by the code accuracy verification can be utilized as much as possible. When the boot program is executed, it only takes a short time to know the code verification result, thereby promoting the subsequent startup process and improving the startup speed of the BMS.

[0057] Therefore, during the execution of the boot program, the code accuracy verification work for the BMS will be processed in parallel during the execution phase of the boot program, which reduces the startup time of the BMS as much as possible, so that the startup speed of the BMS is optimized.

[0058] S102: When the code verification result is verification passed, network initialization processing is performed on the BMS, and during the network initialization processing, startup data of the BMS is collected.

[0059] After determining that the code verification result of the BMS is passed, in order to enable the BMS to send its own message data according to the configured network to indicate that the BMS has been started, the BMU-Core0 further performs network initialization processing on the BMS to perform network configuration. During the network initialization processing, the BMU-Core1 will further collect the startup data of the BMS, so that the BMS can generate the corresponding startup message through the startup data after the network configuration is completed, thereby declaring its own startup status.

[0060] Specifically, in this step, before the network initialization process is performed, BMU-Core0 will first start the BMS operating system to provide a basis for the execution steps of the network initialization process. After the BMS operating system is started, BMU-Core0 will start the network initialization process, and at the same time, control another BMU-Core1 to collect the startup data of the BMS, thereby controlling the parallel processing of network configuration and data collection, minimizing the time consumed by the BMS in the startup process, and improving the startup speed of the BMS.

[0061] On the other hand, the startup data of the BMS is used to characterize the startup safety of the BMS. In actual application scenarios, the startup data of the BMS can be the voltage and temperature value of the BMS. The voltage and temperature value of the BMS can effectively characterize the voltage condition of the BMS when the startup is completed, so as to characterize the startup safety of the BMS. At the same time, the voltage and temperature value of the BMS is often the startup data that takes the longest time to collect among many startup data. When obtaining the startup data of the BMS, the voltage and temperature value of the BMS, the network initialization status, the HSM initialization status and other data are often used together as the data in the first frame message. Since the collection of the voltage and temperature value of the BMS takes the longest time, whether the voltage and temperature value of the BMS is collected is used as a factor in whether to generate the first frame message, which can avoid statistics on various types of startup data during the generation of the first frame message, thereby improving the generation efficiency of the first frame message while ensuring the integrity of the first frame message.

[0062] Correspondingly, if it is determined that the code verification result for the BMS is not passed, the execution of the boot program is terminated, and a verification error signal is sent to the external interactive terminal. At this time, the boot program will be terminated at the current execution node and wait for the program execution signal initiated by the external interactive terminal again. After re-initializing the BMS, the external interactive terminal can initiate the program to execute the instruction again, so that the boot program can continue to execute based on the current execution node, thereby optimizing the business processing efficiency of the BMS during the startup process.

[0063] S103: After the network initialization process is completed, according to the startup data and the network configuration after the initialization process, a startup message of the BMS is sent to the external interactive terminal.

[0064] In this way, after the network initialization process is completed, the startup data that has been collected and the network configuration after the initialization process can be used to generate the startup message of the BMS through the startup data, and send it to the external interactive terminal. After the BMS completes the startup, its first frame message can be sent to the external interactive terminal, thereby indicating that the BMS has completed the startup.

[0065] The above describes the general process of the BMS startup method in the embodiment of the present application. Next, the process of verifying the code accuracy of the BMS in step S101 will be introduced in conjunction with the specific embodiment drawings.

[0066] See also Figure 3 , which is a flow chart of a BMS code accuracy verification method provided in an embodiment of the present application, and specifically includes the following steps:

[0067] S201: When the boot program starts to execute, MAC calculation is performed according to the preset code verification address to obtain an actual MAC value corresponding to the preset code verification address.

[0068] As can be seen from the previous article, the preset verification parameters of the BMS are used to characterize the parameters that need to be applied when verifying the accuracy of the BMS code. Among them, the preset verification parameters include the preset MAC expected value and the preset code verification address. The preset code verification address determines the specific area range where the HSM needs to read data from the memory. The HSM will perform MAC calculation based on the APP code within this area to obtain the actual MAC value for the code within this area.

[0069] Before the HSM calculates the actual MAC value, it needs to receive the preset code verification address and the preset MAC expected value sent by the MCU. The MCU needs to extract the stored preset code verification address and the preset MAC expected value from the specified address of Hex and send them to the HSM.

[0070] Specifically, when the HSM receives the preset code verification address and the preset MAC expected value sent by the MCU, it first needs to determine the verification code area indicated by the preset code verification address from its own memory based on the received preset code verification address. Subsequently, in order to ensure that the MAC value calculation process is performed in a secure and encrypted environment, the HSM needs to determine whether the code in the verification code area contains a preset key. If there is a preset key in this verification code area, it means that the MAC value calculation process can be performed in a secure and encrypted environment. Then, the MAC value is calculated for the code data in the verification code area through the preset key and the preset encryption algorithm to obtain the actual MAC value corresponding to the preset code verification address.

[0071] In one possible implementation, the preset encryption algorithm used by the HSM to calculate the actual MAC value may be the AES algorithm, which is a symmetric encryption algorithm widely used in data transmission and storage. By executing the AES algorithm through an acceleration engine in the HSM, the calculation speed of the actual MAC value in a specific verification code area can be greatly improved, and the integrity and security of the code in the BMS can be ensured through the symmetric encryption characteristics of the AES algorithm.

[0072] Correspondingly, if there is no preset key in the verification code area, the MAC value calculation step is not performed. For details, please refer to Figure 4 A flowchart of a method for calculating an actual MAC value disclosed, combined with Figure 4 The above process of calculating the MAC value by the HSM is understood and will not be described in detail in this embodiment.

[0073] S202: Compare the actual MAC value with the preset MAC expected value to verify the code accuracy of the verification code area indicated by the preset code verification address to obtain the code verification result.

[0074] After the HSM calculates the actual MAC value corresponding to the preset code verification address, the HSM compares the actual MAC value with the preset MAC expected value, and can complete the code accuracy verification for the verification code area through the corresponding comparison result, thereby obtaining the final code verification result.

[0075] Specifically, in the process of comparing the actual MAC value with the preset MAC expected value, if the actual MAC value is the same as the preset MAC expected value, it indicates that the boot program of the BMS and its internal initialization configuration perfectly follow the execution of the boot program, and the accuracy of the code in the BMS is normal, and the corresponding code verification result is verification passed. Correspondingly, if the actual MAC value is different from the preset MAC expected value, it indicates that the code in the BMS is abnormal, and the corresponding code verification result is determined to be verification failed.

[0076] The above is the entire process of HSM verifying the code accuracy for BMS. It can be seen that the embodiment of the present application provides a BMS startup method, in which, when responding to the BMS startup instruction to execute the boot program, the code accuracy of the BMS will be verified synchronously through the preset verification parameters during the execution of the boot program, so as to realize the parallel processing of the boot program execution and the code accuracy verification, thereby effectively reducing the time consumed by the boot program execution and code verification. Subsequently, after the code verification result for the BMS is verified, the BMS is initialized for the network so that the BMS sends the first frame message to the external interactive terminal through the initialized network configuration. Accordingly, in the process of the BMS performing the network initialization processing, the startup data of the BMS is synchronously collected to provide a data basis for the first frame message that the BMS needs to send. In this way, when the BMS completes the initialization processing for the network, it can immediately send its own startup message to the external interactive terminal according to the corresponding startup data and network configuration. The various transactions that the BMS needs to process at startup are processed in parallel, which saves the startup time of the BMS to the greatest extent and optimizes the startup speed of the BMS.
