[0057] Energy storage refers to the process of storing energy through a medium or device and releasing it when needed. To ensure the normal operation of an energy storage system, it is often necessary to upgrade the system, for example, by upgrading the Sub Battery Management Unit (SBMU) within the system.

[0058] Currently, SBMUs can be installed inside valve towers or containers. When upgrading an SBMU, if it's installed in a valve tower, professionals need to climb the tower and manually transmit the upgrade data. However, due to the high operating voltage of the valve tower, manually transmitting upgrade data poses significant safety risks, increasing the overall safety risks during energy storage system upgrades.

[0059] During the upgrade of the SBMU, if the SBMU is located inside a container where access is prohibited, the SBMU will be unable to receive external upgrade data, resulting in the failure of the energy storage system upgrade.

[0060] To address the aforementioned issues, this application provides an energy storage system upgrade method, upgrade device, energy storage system, and storage medium. The energy storage system upgrade method is applied to a battery management controller in the energy storage system. The energy storage system also includes a sub-battery management unit, with the battery management controller connected to the sub-battery management unit. The energy storage system upgrade method includes: sending a connection request to the sub-battery management unit, enabling the sub-battery management unit to establish a communication connection with the battery management controller based on the connection request; and sending first data to the sub-battery management unit based on the communication connection, enabling the sub-battery management unit to perform an upgrade based on the first data. During the upgrade process of the sub-battery management unit, the first data used for upgrading the sub-battery management unit is transmitted to the sub-battery management unit based on the battery management controller. This eliminates the need for professionals to climb the valve tower where the sub-battery management unit is installed to manually transmit the first data to the sub-battery management unit, reducing the safety risks during the energy storage system upgrade process.

[0061] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0062] Please refer to Figure 1, which shows a schematic diagram of an application scenario of the energy storage system provided in this application embodiment. The energy storage system may include a Battery Management Controller (BMC) 100 and a Sub Battery Management Unit (SBMU) 200. The BMC 100 can be communicatively connected to the SBMU 200 and interact with the SBMU 200 based on the communication connection.

[0063] The communication connection can be any of the following, including but not limited to FT3 communication connection, Socket communication connection, or Controller Area Network (CAN) communication connection.

[0064] For example, the BMC 100 can be connected to the SBMU 200 via an FT3 fiber optic interface, an Ethernet interface, or a CAN interface, etc.

[0065] The BMC 100 can be a Master Battery Management Unit (MBMU).

[0066] Please refer to Figure 2, which shows a flowchart of an energy storage system upgrade method provided in one embodiment of this application. In a specific embodiment, the energy storage system upgrade method can be applied to BMC 100 in the energy storage system. The process shown in Figure 2 will be described in detail below using BMC 100 as an example. The energy storage system upgrade method may include the following steps 110 to 130.

[0067] Step 110: Send a connection request to the sub-battery management unit so that the sub-battery management unit can establish a communication connection with the battery management controller according to the connection request.

[0068] In this embodiment of the application, when a user needs to upgrade the energy storage system, an upgrade command can be sent to the BMC. The BMC receives and responds to the upgrade command, and sends a connection request to the SBMU. The SBMU receives and responds to the connection request and establishes a communication connection with the BMC.

[0069] In some implementations, the BMC may be equipped with a voice recognition module. When a user needs to upgrade the energy storage system, the user can send voice information within the voice acquisition range of the voice recognition module. The voice recognition module collects the voice information sent by the user, performs voice recognition on the collected voice information, and determines that the recognition result contains keywords indicating the need to upgrade the energy storage system. For example, the keywords are "energy storage system upgrade", or "energy storage system" and "upgrade", etc., then it is determined that an upgrade instruction to indicate the need to upgrade the energy storage system has been received.

[0070] As an example, if the user's voice message is: "Upgrade the energy storage system", and the voice recognition result contains the keywords "energy storage system" and "upgrade", then it is determined that an upgrade instruction to instruct the energy storage system to be upgraded has been received.

[0071] In some implementations, the energy storage system may also include a client that can connect to the BMC via a network and interact with the BMC via the network.

[0072] When a user needs to upgrade the energy storage system, they can send an upgrade command to the client. The client receives and responds to the upgrade command, and forwards it to the BMC via the network. The BMC then receives the upgrade command forwarded by the client.

[0073] The client can be, but is not limited to, any of the following: mobile client (e.g., mobile phone client, PDA client, Tablet PC client, laptop client, smartwatch client, smart bracelet client, or wearable client) or fixed client (e.g., desktop computer client, smart panel client).

[0074] The network may include, but is not limited to, any of the following: ZigBee network, Bluetooth (BT) network, Wireless Fidelity (Wi-Fi) network, Thread network, Long Range Radio (LoRa) network, Low-Power Wide-Area Network (LPWAN), Infrared network, Narrow Band Internet of Things (NB-IoT), Controller Area Network (CAN), Digital Living Network Alliance (DLNA) network, Wide Area Network (WAN), Local Area Network (LAN), Metropolitan Area Network (MAN), or Wireless Personal Area Network (WPAN).

[0075] Step 130: Send first data to the sub-battery management unit based on the communication connection so that the sub-battery management unit can upgrade according to the first data.

[0076] In this embodiment, the BMC can send first data to the SBMU via a communication connection. The SBMU receives and responds to the first data and performs an upgrade based on the first data. During the upgrade of the SBMU, the BMC transmits the first data used for the upgrade of the SBMU to the SBMU, eliminating the need for professionals to climb the valve tower where the SBMU is installed to manually transmit the first data to the SBMU, thus reducing the safety risks during the upgrade process of the energy storage system.

[0077] The first data can be used to upgrade the SBMU, and the first data can be any of the following, including but not limited to FT3 protocol data, TCP data packets, or CAN protocol data.

[0078] The solution provided in this application involves a battery management controller sending a connection request to a sub-battery management unit (SBMU), enabling the SBMU to establish a communication connection with the controller and send first data to the SBMU based on the connection. This allows the SBMU to perform an upgrade based on the first data. During the upgrade process, the controller transmits the first data used for the upgrade to the SBMU, eliminating the need for professionals to climb the valve tower where the SBMU is installed to manually transmit the first data, thus reducing safety risks during the upgrade process of the energy storage system.

[0079] Please refer to Figure 3, which shows a flowchart of an energy storage system upgrade method provided in another embodiment of this application. In a specific embodiment, the energy storage system upgrade method can be applied to BMC 100 in the energy storage system. The process shown in Figure 3 will be described in detail below using BMC 100 as an example. The energy storage system upgrade method may include the following steps 210 to 250.

[0080] Step 210: Send a connection request to the sub-battery management unit so that the sub-battery management unit can establish a communication connection with the battery management controller according to the connection request.

[0081] In this embodiment, step 210 can be referred to the corresponding steps in the previous embodiments, and will not be repeated here.

[0082] Step 230: Convert the second data according to the first communication protocol corresponding to the communication connection to obtain the first data.

[0083] In this embodiment, the BMC can convert the second data according to the first communication protocol corresponding to the communication connection to obtain the first data. The second data is the data used to upgrade the SBMU. Converting the second data used to upgrade the SBMU into the first data that matches the first communication protocol for transmission can reduce data loss during data transmission and help improve the success rate of upgrading the energy storage system.

[0084] The first communication protocol may include, but is not limited to, any one of the following: the FT3 communication protocol corresponding to the FT3 communication connection, the TCP communication protocol corresponding to the Socket communication connection, or the CAN communication protocol corresponding to the CAN communication connection.

[0085] The data type of the second data is different from that of the first data. The second data can be any of the following, including but not limited to TCP data packets, CAN protocol data, or FT3 protocol data.

[0086] In some implementations, the first communication protocol may be the FT3 communication protocol, and the first data may be FT3 protocol data corresponding to the FT3 communication protocol.

[0087] When a user needs to upgrade the energy storage system, they can send an upgrade command to the BMC. The BMC receives and responds to the upgrade command, and converts the second data according to the FT3 communication protocol to obtain FT3 protocol data.

[0088] In some implementations, the first communication protocol may be the TCP communication protocol, and the first data may be a TCP data packet corresponding to the TCP communication protocol.

[0089] When a user needs to upgrade the energy storage system, they can send an upgrade command to the BMC. The BMC receives and responds to the upgrade command, and converts the second data according to the TCP communication protocol to obtain TCP data packets.

[0090] In some implementations, the first communication protocol may be the CAN communication protocol, and the first data may be CAN protocol data corresponding to the CAN communication protocol.

[0091] When a user needs to upgrade the energy storage system, they can send an upgrade command to the BMC. The BMC receives and responds to the upgrade command, and converts the second data according to the CAN communication protocol to obtain CAN communication protocol data.

[0092] In some implementations, the terminal device can send second data to the BMC based on a second communication protocol. The BMC receives the second data sent by the terminal device based on the second communication protocol and converts the second data according to the first communication protocol to obtain first data. The battery management controller receives the second data sent by the terminal device based on the second communication protocol. When the terminal device is remotely connected to the battery management controller, the user can remotely upgrade the sub-battery management unit based on the terminal device, which is beneficial to improving the user experience during the energy storage system upgrade process.

[0093] The second communication protocol can be the TCP communication protocol, and the second data is the initial TCP data packet. The terminal device and the BMC are connected through the TCP communication protocol. The terminal device can remotely communicate with the BMC, which is beneficial to improving the user experience during the upgrade process of the energy storage system.

[0094] Terminal devices may include, but are not limited to, mobile terminal devices (e.g., mobile phones, PDAs, Tablet PCs, laptops, smartwatches, smart bracelets, etc.) and fixed terminal devices (e.g., TCUs, desktop computers, smart panels, all-in-one computers, etc.).

[0095] Step 250: Send first data to the sub-battery management unit based on the communication connection, so that the sub-battery management unit converts the first data into second data and performs an upgrade based on the second data.

[0096] In this embodiment, the BMC can send first data to the SBMU based on the communication connection. The SBMU receives and responds to the first data, converts the first data to obtain second data, and upgrades based on the second data. During the upgrade of the SBMU, the second data used to upgrade the SBMU is converted into first data that matches the first communication protocol for transmission, which can reduce data loss during data transmission and help improve the success rate of upgrading the energy storage system.

[0097] In some implementations, the first communication protocol may be the FT3 communication protocol, and the first data may be FT3 protocol data.

[0098] The BMC can convert the second data according to the FT3 communication protocol to obtain FT3 protocol data, and send the FT3 protocol data to the SBMU based on the communication connection. The SBMU receives and responds to the FT3 protocol data, converts the FT3 protocol data to obtain the second data, and performs upgrades based on the second data. During the upgrade of the SBMU, the BMC transmits the second data to the SBMU based on the FT3 communication protocol. Since the FT3 communication transmission rate is relatively fast, it is beneficial to improve the upgrade efficiency of the energy storage system.

[0099] In some implementations, the BMC can split the second data to obtain split data, reassemble the split data to obtain the second data, and convert the second data according to the first communication protocol corresponding to the communication connection to obtain the first data. The first data is then sent to the SBMU based on the communication connection. The SBMU receives and responds to the first data, converts the first data to obtain the second data, and upgrades based on the second data. During the internal transmission of the second data, the BMC splits the second data before transmission, which can reduce the amount of second data sent in a single transmission, reduce data transmission errors, and reassemble the split data back into the second data, which is beneficial to improving the stability and accuracy of the second data transmission.

[0100] In one application scenario, the energy storage system may include a BMC and an SBMU. The BMC is connected to the SBMU via an FT3 fiber optic interface and to a terminal device (PC) via an Ethernet interface. The first communication protocol may be the FT3 communication protocol, the first data may be an initial TCP data packet, the second communication protocol may be the TCP communication protocol, and the second data may be FT3 protocol data. As shown in Figure 4, the energy storage system upgrade method may include steps 301 to 315.

[0101] Step 301: The BMC receives the initial TCP data packet sent by the PC.

[0102] The PC sends the initial TCP data packet to the SBMU based on the TCP communication protocol.

[0103] Step 303: BMC splits the initial TCP packets to obtain split TCP packets.

[0104] Step 305: BMC reassembles the split TCP packets to obtain the initial TCP packets.

[0105] Step 307: The BMC converts the initial TCP data packet according to the FT3 communication protocol to obtain FT3 protocol data.

[0106] Step 309: The BMC sends FT3 protocol data to the SBMU based on the FT3 communication protocol.

[0107] Step 311: SBMU re-converts the FT3 protocol data to obtain the initial TCP data packets.

[0108] Step 313: SBMU splits the initial TCP packets to obtain split TCP packets.

[0109] Step 315: SBMU reassembles the split TCP packets to obtain the initial TCP packets.

[0110] The solution provided in this embodiment involves the battery management controller sending a connection request to the sub-battery management unit, enabling the sub-battery management unit to establish a communication connection with the battery management controller based on the connection request. The sub-battery management unit then converts the second data according to the first communication protocol corresponding to the communication connection to obtain first data, and sends the first data to the sub-battery management unit based on the communication connection. This allows the sub-battery management unit to convert the first data back to the second data and perform an upgrade based on the second data. During the upgrade process of the sub-battery management unit, the battery management controller transmits the first data used for the upgrade to the sub-battery management unit, eliminating the need for professionals to climb the valve tower where the sub-battery management unit is installed to manually transmit the first data, thus reducing the safety risks during the upgrade process of the energy storage system.

[0111] Furthermore, during the upgrade of the sub-battery management unit, the second data used for upgrading the sub-battery management unit is converted into first data that matches the first communication protocol for transmission. This reduces data loss during data transmission and helps improve the success rate of upgrading the energy storage system.

[0112] Please refer to Figure 5, which shows a flowchart of an energy storage system upgrade method provided in another embodiment of this application. In a specific embodiment, the energy storage system upgrade method can be applied to the SBMU 200 in the energy storage system. The process shown in Figure 5 will be described in detail below using the SBMU 200 as an example. The energy storage system upgrade method may include the following steps 410 to 430.

[0113] Step 410: In response to the connection request sent by the battery management controller, establish a communication connection with the battery management controller.

[0114] In this embodiment, when a user needs to upgrade the energy storage system, they can send an upgrade command to the BMC. The BMC receives and responds to the upgrade command, sends a connection request to the SBMU, and the SBMU receives and responds to the connection request, establishing a communication connection with the BMC.

[0115] In some implementations, when a user needs to upgrade the energy storage system, an upgrade command can be sent to the BMC. The BMC receives and responds to the upgrade command, sends a connection request to the SBMU, the SBMU receives and responds to the connection request, establishes a communication connection with the BMC, and sends a connection confirmation message to the BMC based on the communication connection. The BMC receives the connection confirmation message sent by the SBMU.

[0116] In some implementations, when a user needs to upgrade the energy storage system, an upgrade command can be sent to the BMC. The BMC receives and responds to the upgrade command, sends a connection request to the SBMU, the SBMU receives and responds to the connection request, establishes a communication connection with the BMC, and sends a connection confirmation message to the BMC based on the communication connection. The BMC receives the connection confirmation message sent by the SBMU and sends first data to the SBMU based on the communication connection.

[0117] The first data can be used to upgrade the SBMU, and the first data includes, but is not limited to, any one of TCP packets, CAN protocol data, or FT3 protocol data.

[0118] Step 430: Receive the first data sent by the battery management controller based on the communication connection, and perform the upgrade according to the first data.

[0119] In this embodiment, the SBMU can receive the first data sent by the BMC based on the communication connection and upgrade according to the first data. During the upgrade process of the SBMU, the first data used for the upgrade of the SBMU is transmitted to the SBMU based on the BMC. This eliminates the need for professionals to climb to the valve tower where the SBMU is installed to manually transmit the first data to the SBMU, thus reducing the safety risks during the upgrade process of the energy storage system.

[0120] In some implementations, the BMC can be connected to the SBMU based on a first communication protocol, and the first data can be obtained by converting the second data based on the BMC according to the first communication protocol.

[0121] The SBMU can receive the first data sent by the BMC based on the communication connection, convert the first data to obtain the second data, and upgrade based on the second data.

[0122] In some implementations, the SBMU can receive first data sent by the BMC based on the communication connection, convert the first data to obtain second data, split the second data to obtain split data, reassemble the split data to obtain second data, and upgrade based on the second data. During the internal transmission of the second data, the SBMU splits the second data before transmitting it, which can reduce the amount of second data sent in a single transmission, reduce data transmission errors, and reassemble the split data back into second data, which is beneficial to improving the stability and accuracy of the second data transmission.

[0123] The solution provided in this embodiment involves the sub-battery management unit responding to a connection request sent by the battery management controller, establishing a communication connection with the battery management controller, receiving first data sent by the battery management controller based on the communication connection, and performing an upgrade based on the first data. During the upgrade process of the sub-battery management unit, the battery management controller transmits the first data used for the upgrade of the sub-battery management unit to the sub-battery management unit, eliminating the need for professionals to climb the valve tower where the sub-battery management unit is installed to manually transmit the first data to the sub-battery management unit, thus reducing the safety risks during the upgrade process of the energy storage system.

[0124] Please refer to Figure 6, which illustrates an energy storage system upgrade device 500 provided in one embodiment of this application. In a specific embodiment, the energy storage system upgrade device 500 can be applied to the BMC 100 in the energy storage system. The energy storage system upgrade device 500 shown in Figure 6 will be described in detail below using the BMC 100 as an example. The energy storage system upgrade device 500 may include a connection request sending module 510 and an upgrade data sending module 530.
