Description

Technical Field

[0001] This invention relates to the field of battery management technology, and more specifically to an energy storage battery management system and interface configuration method, and a battery device. Background Technology

[0002] The energy storage battery management system includes a BAU (Battery Array Management Unit), a BCU (Battery Cluster Management Unit), and a BMU (Battery Cell Management Unit). The BAU manages multiple BCUs and the batteries within the entire array, and interacts with external devices (e.g., EMS (Energy Management System), PCS (Power Conversion System)). The BCU manages the collection and processing of battery cluster information, as well as the data processing of all BMUs within the cluster. The BMU collects basic battery information, such as cell voltage and temperature. Currently, BAUs, BCUs, and BMUs generally communicate via wired connections, primarily using CAN bus. This approach cannot meet the diverse needs of increasingly diverse application scenarios. Furthermore, each communication interface is limited by communication protocols and specifications, allowing only a limited number of external devices to be connected, resulting in insufficient flexibility in field applications and an inability to adapt to new architectural requirements in a timely manner. In existing technologies, product design is carried out on a one-to-one basis for various needs in different application scenarios. Every time the requirements change, the hardware and software need to be redesigned. After the hardware and software fully meet the application requirements, environmental adaptation is carried out. This not only involves a high workload and requires frequent hardware and software development, but also hinders future expansion and maintenance. Summary of the Invention

It should be noted that, in this embodiment, as... Figure 2As shown, the BAU (Battery Array Management Unit 11), BCU (Battery Cluster Management Unit 12), and BMU (Battery Cell Management Unit 13) are the core components of the energy storage battery management system 10. Communication between these three units is internal communication, which can employ wired communication, wireless communication, or a hybrid of wired and wireless communication. It should also be noted that, in this embodiment, wireless communication within the internal communication includes, but is not limited to, WiFi, Bluetooth, wireless carrier communication, radio waves, magnetic induction communication, light waves, and sound waves; WiFi and wireless carrier communication are preferred to meet the requirements of higher communication rates and data volumes. Wired communication within the internal communication includes, but is not limited to, CAN, Ethernet, RS485, USB, LVDS, HDMI, DP, chain communication, unidirectional ring communication, and bidirectional ring communication; Ethernet and CAN communication are preferred to meet the requirements of higher communication rates and data volumes. Understandably, wired communication within the internal communication can be non-isolated or isolated. Isolation methods include, but are not limited to, optical isolation, magnetic isolation, and capacitive isolation to meet the requirements of signal isolation, filtering, and withstand voltage in different applications.

[0039] In some embodiments, such as this embodiment, as Figure 1 and Figure 3As shown, the first communication interface set also includes a wired BAU external communication interface 113, a wireless BAU external communication interface 114, and a hybrid BAU external communication interface 115; the first external device set includes wireless BAU external devices, hybrid BAU external devices, and wired BAU external devices; the wireless BAU external devices communicate wirelessly with the wireless BAU external communication interface 114, the hybrid BAU external devices communicate wiredly or wirelessly with the hybrid BAU external communication interface 115, and the wired BAU external communication interface 113 communicates wiredly with the wired BAU external devices. It should be noted that in this embodiment, the BAU external device connection involves many external devices, including but not limited to BCU, debugging equipment, host computer, EMS (Energy Management System), fire protection, control panel, time synchronization, cooling, power grid, electricity meter, PCS (Power Conversion System), STS (Static Transfer Switch), application APP device, screen, USB flash drive, hard drive, mouse, and cloud platform devices. The wired BAU external device includes debugging equipment, EMS, host computer, fire protection system, control panel, time synchronization system, cooling system, power grid, electricity meter, PCS, STS, USB flash drive, hard drive, mouse, and screen. The application APP device is used as the wireless BAU external device. The cloud platform is used as the hybrid BAU external device. It should also be noted that in this embodiment, the wired BAU external communication interface 113 communicates with the wired BAU external device using CAN, Ethernet, 485 bus, or USB. The wired BAU external communication interface 113 can also communicate with the wired BAU external device using LVDS / HDMI / DP / DVI / VGA. The wireless BAU external device communicates with the wireless BAU external communication interface 114 using Bluetooth. The hybrid BAU external device communicates with the hybrid BAU external communication interface 115 using 4G / Ethernet / WiFi. Understandably, the communication cable connected to the wired BAU external device can be of the same type or different types.

[0040] In some embodiments, such as this embodiment, as Figure 3 As shown, the wired BAU external device includes an energy management system and an energy conversion system. The energy management system is digitally connected to the battery array management unit 11, and the energy conversion system is digitally connected to the battery array management unit 11. It should be noted that in this embodiment, to ensure the reliable transmission of critical information between the BAU and EMS, and between the BAU and PCS, an additional digital connection is added to improve system security. Even in extreme situations such as communication outages or data congestion, communication effectiveness can be guaranteed.

[0041] In some embodiments, such as this embodiment, as Figure 1 and Figure 4As shown, the second communication interface set also includes two wired BCU external communication interfaces 123, a wireless BCU external communication interface 124, and a hybrid BCU external communication interface 125. The second external device set includes wired BCU external devices, hybrid BCU external devices, and wireless BCU external devices. The wired BCU external devices communicate with the wired BCU external communication interface 123 via wired communication, the wireless BCU external devices communicate wirelessly with the wireless BCU external communication interface 124 via wireless communication, and the hybrid BCU external devices communicate with the hybrid BCU external communication interface 125 via wired or wireless communication. It should be noted that in this embodiment, the BCU's external device connections involve many external devices, including but not limited to debugging equipment, host computers, cooling systems, fire suppression systems, time synchronization systems, PCS systems, and DC / DC devices. Cooling systems, fire suppression systems, time synchronization systems, PCS systems, and DC / DC devices are designated as wired BCU external devices. These wired BCU external devices communicate with the wired BCU external communication interface 123 via CAN or RS-485. The debugging equipment and host computer are designated as hybrid BCU external devices, which communicate with the hybrid BCU external communication interface 125 via Ethernet, CAN, WiFi, or Bluetooth. It should also be noted that in this embodiment, the BMU primarily communicates via CAN or a bidirectional ring network. Furthermore, in this embodiment, the communication lines connected to the wired BCU external devices can be of the same type or different types.

[0042] In some embodiments, such as this embodiment, as Figure 4 As shown, the wired BCU external device includes an energy conversion system and a DC / DC converter. The DC / DC converter is digitally connected to the battery cluster management unit 12, and the energy conversion system is digitally connected to the battery cluster management unit 12. It should be noted that in this embodiment, to ensure the reliable transmission of critical information between the BCU and the DC / DC converter, and between the BCU and the PCS, an additional digital connection is added to improve system security. Even in extreme situations such as communication failures or data congestion, communication effectiveness can be guaranteed.

[0043] In some embodiments, such as this embodiment, as Figure 1 and Figure 5As shown, the battery cell management unit 13 is configured with wired and wireless communication modes, including a wired BMU external communication interface 131, a wireless BMU external communication interface 132, and a hybrid BMU external communication interface 133. The wired BMU external communication interface 131 enables wired communication with external wired BMU devices, the wireless BMU external communication interface 132 enables wireless communication with external wireless BMU devices, and the hybrid BMU external communication interface 133 enables wired or wireless communication with external hybrid BMU devices. It should be noted that in this embodiment, the BMU connection to external devices involves many devices, including but not limited to cooling, fire protection, and gas sensors. Cooling and fire protection are treated as wired BMU external devices, which connect to the wired BMU external communication interface 131 via RS-485 or CAN. It should also be noted that, in this embodiment, the communication line connected to the wired BMU external device can be of the same type or of different types; understandably, the battery cell management unit 13 has built-in multiple communication protocols corresponding to the wired BMU external device, the wireless BMU external device and the hybrid BMU external device, as well as multiple communication protocols corresponding to the multiple communication protocols.

[0044] In some embodiments, such as this embodiment, the battery array management unit 11 and the battery cluster management unit 12 are respectively equipped with multiple communication protocols corresponding to the first external device set and the second external device set, as well as multiple communication protocols corresponding to the multiple communication protocols. It should be noted that, in this embodiment, the BAU and BCU incorporate multiple communication protocols based on application scenario requirements, such as Modbus RTU, Modbus TCP, DL / T634.5104, DL / T 860, IEC61850, and IEC104. Simultaneously, the BAU also incorporates communication protocols corresponding to the first set of external devices, such as EMS communication protocol 01, ..., EMS communication protocol N, PCS communication protocol 01, ..., PCS communication protocol N, meter communication protocol, and time synchronization communication protocol. Similarly, the BCU incorporates communication protocols corresponding to the second set of external devices, such as EMS communication protocol 01, ..., EMS communication protocol N, PCS communication protocol 01, ..., PCS communication protocol N, and time synchronization communication protocol. Understandably, some communication protocols are shared between the BAU and BCU.

[0045] Reference Figure 6 , Figure 6This document illustrates a flowchart of an embodiment of an interface configuration method for an energy storage battery management system 10 according to the present invention. This interface configuration method is applied to the aforementioned energy storage battery management system 10, using any one of the battery array management unit 11, battery cluster management unit 12, and battery cell management unit 13 in the energy storage battery management system 10 as the main processing unit, and the other two units as auxiliary processing units. The specific implementation steps of the energy storage battery management system 10 of the present invention will be further described in detail below using this method. Figure 6 As shown, the method includes steps S110-S120:

[0046] S110. The main processing unit obtains interface configuration information and parses and classifies the interface configuration information to obtain interface parsing main information and interface parsing auxiliary information. The interface parsing main information and the interface parsing auxiliary information both include the name of the enabled interface, the name of the external device connected to the enabled interface, and the communication rate, data format, frame format, communication protocol and communication rules used by the enabled interface.

[0047] S120. The main processing unit sets its own preset operating parameters according to the main information parsed by the interface, and sends the auxiliary information parsed by the interface to the auxiliary processing unit, so that the auxiliary processing unit sets its own preset operating parameters according to the auxiliary information parsed by the interface.

[0048] In this embodiment of the invention, each communication interface in the first and second communication interface sets of the entire energy storage battery management system 10 has multiple configuration options, including name, external device name, communication rate, communication protocol, and communication rules. These options can be entered through factory settings, on-site configuration, and remote settings. For factory settings, direct input via program flashing is preferred. For projects with fixed configurations, direct input reduces subsequent configuration workload and improves installation and debugging efficiency. For on-site configuration, a host computer or control panel is preferred, allowing for timely adjustments based on the application, providing greater flexibility. For remote settings, remote configuration adjustments are preferred via a cloud platform. This ensures clear communication between on-site and remote personnel, enabling timely deployment of product applications, improving product upgrade efficiency, and reducing repetitive work and implementation cycles.

[0049] Furthermore, each communication interface will have multiple configuration items to facilitate adjustments to the interface's actual application. Configuration parameters include, but are not limited to: whether the communication interface is enabled (i.e., the name of the enabled interface), the peripheral type corresponding to the enabled interface, the basic parameter configuration of the enabled interface, the communication protocol configuration of the connected device, and the communication protocol configuration of the connected device; among these, whether the communication interface is enabled is specified. Figure 7As shown, hierarchical management or single-interface management can be adopted. In hierarchical management, all interfaces can be differentiated according to communication interface type. For example, different interfaces such as CAN and Ethernet can each have a master switch or flag to enable or disable all interfaces of the same type. Then, each individual interface can have its own switch or flag to enable or disable that individual interface. Understandably, single-interface management only requires setting an independent flag for each individual interface. The hierarchical management mode is preferred. Through flag settings, the meaning of the flags can be defined beforehand, for example, 1 represents enabled, and 0 represents disabled. The enabled interface corresponds to the peripheral type, such as... Figure 8 As shown, different communication interface types, or different units with the same type of interface, can be connected to different or the same type of external device. External device types include, as mentioned earlier, EMS, PCS, screens, meters, etc. That is, different communication interface types can connect to different types of external devices, and different units with the same type of interface can connect to the same external device. Enable basic interface parameter configuration, such as... Figure 9 As shown, parameters such as baud rate, data format, and frame format are required for each communication interface. When configuring each communication interface, the system can automatically associate the necessary configuration items for that interface. External device communication protocol configuration, such as... Figure 10 As shown, the communication interface of the external device can be confirmed and matched with the corresponding communication protocol to ensure that normal communication can be completed between the two; the communication protocol configuration of the external device is as follows. Figure 10 The diagram shows how to confirm the communication interface of the external device and match it with the corresponding communication protocol to ensure that both devices use the same communication protocol.

[0050] As described above, after setting the interface configuration parameters through any of the three modes—factory entry, on-site configuration, and remote setting—the main processing unit acquires the interface configuration information and parses and categorizes it to obtain primary and secondary interface parsing information. Both primary and secondary interface parsing information include the name of the enabled interface, the name of the external device connected to the enabled interface, and the communication rate, data format, frame format, communication protocol, and communication rules used by the enabled interface. The main processing unit sets its preset operating parameters based on the primary interface parsing information and sends the secondary interface parsing information to the secondary processing unit, enabling the secondary processing unit to set its preset operating parameters based on the secondary interface parsing information. Understandably, the interface configuration information can be interface configuration information entered by the on-site operating device 20, interface configuration information entered by the remote operating device 30, or interface configuration information entered at the factory.

[0051] Specifically, the factory setup involves setting the corresponding operating parameters for different configuration options in the software program of the energy storage battery management system 10. These operating parameters include operating variables, flag bits, and storage areas. Before program burning, the corresponding values ​​are set according to the actual application to ensure that relevant communication modules are enabled or disabled. For example: Figure 11 As shown, the CAN module is enabled, other interfaces are disabled, the CAN2 interface connects to the peripheral PCS, and uses a communication rate of 500kbps, extended frames, big-endian format, and communication protocol 1 and communication protocol 4. These parameters are directly burned into the corresponding storage space to determine the corresponding functions and definitions. Understandably, the meaning, name, size, and storage area of ​​each variable or flag will be fully defined in the program.

[0052] More specifically, the interface configuration information is the first interface configuration information. The main processing unit acquiring the interface configuration information includes: the main processing unit acquiring the first interface configuration information, wherein the first interface configuration information is information pre-set by the field operation device 20, i.e., the interface configuration information entered into the field operation device 20. In practical applications, the field operation device 20 is first connected to the host computer and control panel via wired communication such as CAN, Ethernet, or 485. Configuration is then performed on the operation interface of the field operation device 20. To facilitate operation, a visual drop-down menu or checkbox is used for configuration. For example, as... Figure 12 As shown, by clicking on the operation interface, 485 communication is disabled, Ethernet communication is enabled, but no specific application is configured. CAN is enabled, the CAN1 interface is opened, and the PCS is connected, using a 500kbps communication rate, extended frames, big-endian format, communication protocol 1, and communication protocol 4. After selection, a configuration message is sent via the communication configuration button. Assuming that a host computer is used for configuration, and the connection method is Ethernet, after clicking the communication configuration button, the host computer message is sent via Ethernet to the main processing unit in the energy storage battery management system 10. It can be understood that since the main processing unit is any one of the battery array management unit 11, the battery cluster management unit 12, and the battery cell management unit 13, the host computer message can be sent to any one of the BAU, BCU, and BMU controllers. After receiving the host computer message, the controller parses and classifies the message to obtain the main interface parsing information and the auxiliary interface parsing information. The main processing unit and the auxiliary processing unit configure corresponding flag bits, thereby changing the start / stop and parameter status of the original communication interface. Figure 13As shown, after the CAN and Ethernet start / stop flags and the 485 flag (000) of the communication interface are converted to 101, thus enabling the CAN and Ethernet modules, the controller notifies the host computer of successful configuration by uploading a message. Understandably, if configuration fails, the controller will upload a fault report to the host computer for troubleshooting. It should be noted that in this embodiment, the interface configuration of the control panel and the host computer is performed at the factory to facilitate later use and maintenance.

[0053] More specifically, the interface configuration information is second interface configuration information, and the main processing unit obtaining the interface configuration information includes: the main processing unit obtaining the second interface configuration information, which is information preset by the remote operation device 30, that is, the interface configuration information entered by the remote operation device 30. In practical applications, such as Figure 14 As shown, remote configuration is initiated by a cloud-based APP, passes through a cloud server, and finally reaches the main processing unit via EMS. The cloud-based APP can input and issue commands via conventional devices such as mobile phones and computers, or it can be implemented through a specially configured control screen. The interactive interface of the cloud-based APP adopts the style and architecture of on-site application configuration, using a visual design to facilitate operator use. It should be noted that in this embodiment, the cloud-based APP differs from on-site application configuration in two key aspects: the scope of configuration objects and the effective time. The objects to be configured can be selected on the cloud-based APP. Controllers connected to the cloud need to be updated in real time in the APP's selectable library and identified by features such as project name, production batch, installation area, software version, product number, and address. The cloud-based APP interface allows for multiple or single selection based on these features, issuing configuration commands to the selected targets and marking the effective time. The configuration commands are relayed to the main processing unit in the energy storage battery management system 10 via the cloud server. The cloud server analyzes the received configuration instructions to identify information such as content, target, and configuration time. It then distributes the interface configuration parameters at a reasonable time. The EMS, acting as the external interface controller for the entire energy storage system, first receives the interface configuration parameters from the cloud server. After performing basic verification, the EMS distributes these parameters to the main processing unit, which, along with the auxiliary processing unit, completes the interface parameter configuration. It should also be noted that in this embodiment, since remote setup requires access to a public network, a security verification mechanism is added throughout the transmission process to ensure the authenticity, validity, and security of data transmission. The cloud server, as the core of information security management, distributes the necessary information for security verification, such as certificates and keys. At each transmission stage—from the cloud APP to the cloud server, from the cloud server to the EMS, and from the EMS to the BAU—security verification is required before proceeding to the next step to ensure the legitimacy of both parties' identities, data integrity, confidentiality, and fairness.
