[0039] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0041] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. These should be regarded as exemplary and are only intended to illustrate the feasibility of implementing the technical solution of this application. However, it does not mean that the applicant has used or necessarily used the relevant content of the solution.

[0042] Figure 1 This is a flowchart illustrating an energy storage system upgrade method according to an embodiment of the present invention. This embodiment is applicable to scenarios involving energy storage system upgrades. The method can be executed by an energy storage system upgrade device, which can be implemented in software and / or hardware and integrated into a computer device.

[0043] like Figure 1 As shown, the upgrade method for energy storage systems includes the following steps:

[0044] S110: Send an upgrade request to the cloud platform and receive data packets sent by the cloud platform to the energy storage system based on the upgrade request.

[0045] The energy storage system includes multiple devices to be upgraded, each with an address code, and the address codes of any two devices to be upgraded are different.

[0046] This embodiment allows for remote upgrades of any device in an energy storage system, such as a semi-solid-state cabinet energy storage system. Specifically, the data packet may contain a binary data packet specifically for upgrading the device, which can be uploaded from a host computer dedicated to upgrading the corresponding energy storage device to the cloud platform.

[0047] An upgrade request can be sent to the cloud platform at a preset upgrade time. Based on the upgrade request, the cloud platform determines the data packet associated with the device in the energy storage system that sent the upgrade request, which is the data packet for software upgrade of the device to be upgraded, and sends it to the energy storage system.

[0048] The equipment to be upgraded can include equipment at any level in the energy storage system.

[0049] S120. Parse the data packet to obtain the address code of the device to be upgraded in the data packet.

[0050] The data packet is parsed to obtain the parsing result, which contains the address code of the device to be upgraded corresponding to the data packet.

[0051] S130: Send data packets to the device to be upgraded, which has an address code.

[0052] Data packets are sent to the device to be upgraded, which has an address code, using a preset communication protocol. The data packets can be sent directly to the target device to be upgraded, or they can be sent step by step, that is, first sent to the upstream device of the device to be upgraded, and then forwarded to the device to be upgraded by the upstream device and intermediate path devices.

[0053] S140. Upgrade the device to be upgraded based on the data packet.

[0054] The data packets are subjected to integrity verification. If the verification passes, the upgrade process is initiated based on the data packets, and the upgrade status is monitored throughout the process. After the data packets stored in the backup storage area are loaded, the software in the running storage area is replaced, completing the software upgrade.

[0055] The technical solution of this embodiment involves sending an upgrade request to a cloud platform and receiving data packets sent by the cloud platform to the energy storage system based on the upgrade request; parsing the data packets to obtain the address codes of the devices to be upgraded; sending data packets to the devices with the address codes; and upgrading the devices according to the data packets. The energy storage system includes multiple devices to be upgraded, each with a unique address code, and the address codes of any two devices are different. This embodiment solves the current problem of the inability to remotely upgrade energy storage devices, enabling remote software upgrades for each device in the energy storage system, improving the efficiency and convenience of software upgrades, and reducing labor costs.

[0056] Figure 2 This is a flowchart illustrating an energy storage system upgrade method provided by an embodiment of the present invention. This embodiment belongs to the same inventive concept as the energy storage system upgrade methods in the above embodiments, and further describes the data packet acquisition process. This method can be executed by an energy storage system upgrade device, which can be implemented in software and / or hardware and integrated into an electronic device with application development capabilities.

[0057] like Figure 2 As shown, the energy storage system upgrade method of this embodiment includes the following steps:

[0058] S210. Determine if the current device needs an upgrade.

[0059] The energy storage system can send a query request containing its own device identifier and current firmware or software version to the cloud platform through a preset communication protocol such as MQTT. After receiving the request, the cloud platform compares it with the latest data packet version corresponding to the device in the database. If an update exists, it will return the version information and the acquisition path. The energy storage system can then confirm whether there is a new data packet available for upgrade.

[0060] S220. Determine whether the current operating condition of the energy storage system is in a valley.

[0061] like Figure 3 As shown, the operating conditions include peak, flat, and valley periods. The valley period can be the time when the energy storage system operates at its lowest point, that is, the time when the grid load is at its lowest level throughout the day; the peak period can be the peak phase, that is, the time when the grid load is at its highest level throughout the day and the demand for electricity is the strongest; the flat period can be the transition period when the grid load is between the peak and valley periods, and the demand for electricity is at a moderate level. The energy storage system can flexibly adjust its charging and discharging strategies according to the actual load conditions to balance the grid supply and demand.

[0062] Peak, flat, and valley periods can be determined by factors such as electricity load data, seasonal variations, user types, and time-sharing standards established by energy policies.

[0063] For example, in industrial and commercial operation scenarios, energy storage systems operate under three conditions: peak hours, flat hours, and off-peak hours, depending on the season. Software upgrades for the three levels of energy storage devices within the system only occur during off-peak hours when there is no charging or discharging activity, and only then will the software upgrade request be sent to the cloud platform. During the upgrade process, the EMS will stop the charging and discharging of the battery system. When the device is being upgraded, any fault information received by the EMS from the energy storage device will be handled specially; for example, the device may stop sending signals to the EMS during the upgrade. The EMS will not conclude that the device has lost communication, nor will it notify the client.

[0064] S230: Stop the charging and discharging of the energy storage system and send an upgrade request to the cloud platform.

[0065] To stop the charging and discharging of the energy storage system, first disconnect the charging and discharging circuit switch to stop the energy interaction between the battery pack and the grid / load, and at the same time shut down the charging and discharging control modules of the energy storage converter and the battery management system to ensure that the system enters a safe standby state with no energy flow.

[0066] The energy storage system's local control unit sends an upgrade request command to the cloud platform according to a preset communication protocol and waits for the cloud platform's response.

[0067] S240: Receive data packets sent by the cloud platform to the energy storage system based on upgrade requests.

[0068] S250: Parse the data packet to obtain the start code, binary upgrade data, discontinuity code, check code, address code of the device to be upgraded, and end code of the data packet.

[0069] like Figure 4 As shown, the data packet is parsed to obtain the parsing results, including a start code, binary upgrade data, a break code, a checksum, a device address code, and an end code. The address code is then extracted from the parsing results. The start code, binary upgrade data, and break code constitute the target upgrade program. The start code, end code, and break code are all fixed codes. The start code identifies whether the upgrade data packet transmission has begun; the end code identifies whether the upgrade data packet transmission has ended; and the break code identifies whether the binary upgrade data packet transmission has been completed and is isolated from the checksum for easy reading. The device address code is set by correspondingly addressing the energy storage device in the upgrade data packet according to the needs. This address allows for precise delivery of the data packet to the device requiring upgrade, avoiding incorrect upgrade targets that could render the energy storage system unusable. The checksum is crucial information used to verify the integrity of the binary upgrade data packet.

[0070] In one alternative implementation, the address code is of type Internet Protocol (IP) address. An IP address is an Internet Protocol address. Any two devices to be upgraded will have different IP addresses.

[0071] To better identify device address information, address assignments were implemented for the three levels of energy storage devices in the energy storage system. This address assignment fully considered the number of devices at each upgrade level in the energy storage system, ensuring sufficient redundancy and compatibility with many series and parallel battery systems. With clear address information, the cloud platform and EMS can easily identify the devices requiring upgrades upon receiving data packets.

[0072] For example, various devices with address codes ranging from 192.168.1.1 to 255 are divided into different IP address ranges: EMS addresses are 192.168.1.1 to 10; PCS addresses are 192.168.1.11 to 20; BCU addresses are 192.168.1.21 to 50; BMU addresses are 192.168.1.51 to 150; serial servers addresses are 192.168.1.151 to 180; electricity meters addresses are 192.168.1.181 to 200; air conditioners addresses are 192.168.1.201 to 260; and water immersion equipment addresses are 192.168.1.261 to 280.

[0073] S260: Send data packets to the device to be upgraded, which has an address code.

[0074] The equipment to be upgraded includes Level 1, Level 2, and Level 3 devices. Each Level 1 device connects to one or more Level 2 devices, and each Level 2 device connects to one or more Level 3 devices. The Level 1 device is the Energy Management System (EMS). Level 2 devices include the Power Conversion System (PCS), Battery Control Unit (BCU), electricity meter, air conditioner, and water immersion sensor. The electricity meter is responsible for calculating charge and discharge capacity. The air conditioner is a crucial component of the energy storage system's thermal management system. The water immersion sensor detects the risk of flooding in the energy storage system. The Level 3 device is the Battery Management Unit (BMU).

[0075] In one optional implementation, sending data packets to the device to be upgraded with an address code can be done by determining the level of the device to be upgraded and sending the data packets to the device level by level.

[0076] In response to the address code being the address code of a primary device, a software upgrade is performed based on the data packet.

[0077] In response to an address code that is the address code of a Level 2 or Level 3 device, a data packet is sent to the Level 2 or Level 3 device so that the Level 2 or Level 3 device can perform a software upgrade based on the data packet.

[0078] For Level 2 devices, data packets can be directly sent to the Level 2 device based on its address code. However, Level 3 devices may need to first send the data to their corresponding Level 2 device, which then forwards it to the Level 3 device. Specifically, in one optional implementation, sending data packets to either the Level 2 or Level 3 device in response to the address code of the Level 2 or Level 3 device can be achieved by sending the data packet to the Level 2 device corresponding to the Level 3 device in response to the address code of the Level 3 device, so that the Level 2 device forwards the data packet to the Level 3 device; wherein, the Level 2 device corresponding to the Level 3 device is a battery control unit.

[0079] In one alternative implementation, a data packet is sent to the device to be upgraded with an address code. Alternatively, the data packet can be loaded into the backup area of ​​the controller of the device to be upgraded. It is then determined whether the data packet loading was successful. If so, the original software in the storage area of ​​the controller is replaced.

[0080] S270, Upgrade the device to be upgraded based on the data packet.

[0081] In one optional implementation, the integrity of the data packet is verified. Verifying the integrity of the data packet can be achieved by performing a function operation on the binary upgrade data using a preset verification function to obtain information to be verified; comparing the information to be verified with a checksum; if the information to be verified and the checksum match, sending a data packet to the device to be upgraded; if the information to be verified and the checksum do not match, stopping data transmission to the device to be upgraded. The integrity of the data packet is verified based on the checksum and binary upgrade data obtained from the parsing, and if the data packet fails the integrity verification, the upgrade is stopped and an upgrade failure message is sent to the cloud platform.

[0082] Based on the checksum and binary upgrade data in the parsed data packet, integrity verification is performed using preset verification algorithms, such as CRC32, MD5, and SHA-1. If the data packet fails the integrity verification, the upgrade is stopped and an upgrade failure message is sent to the cloud platform.

[0083] Specifically, the checksum can be obtained by inputting a checksum function f(x) into the binary upgrade data packet. After receiving the upgrade data packet, the primary device uses the checksum function f(x) to obtain the information to be verified. Then, it compares the received checksum with the calculated information to determine the integrity of the binary upgrade data packet. Software upgrades for energy storage devices can only be performed if the upgrade data packet is complete; otherwise, the energy storage system may malfunction after the software update.

[0084] In one alternative implementation, each primary device, each secondary device, and each tertiary device performs a data packet integrity check before receiving the data packet.

[0085] Specifically, each level 1, level 2, and level 3 device performs a data packet integrity check before receiving the data packet. If the check fails, the software upgrade is terminated and an upgrade failure message is sent to the cloud platform.

[0086] The technical solution of this embodiment determines whether the current device needs an upgrade; if so, it determines whether the current operating condition of the energy storage system is in a valley period; if so, it stops the charging and discharging operation of the energy storage system and sends an upgrade request to the cloud platform; wherein the operating condition includes peak period, flat period, and valley period. It receives data packets sent by the cloud platform to the energy storage system based on the upgrade request; parses the data packets to obtain the start code, binary upgrade data, discontinuity code, check code, address code of the device to be upgraded, and end code of the data packets; sends data packets to the devices to be upgraded that have address codes; and upgrades the devices to be upgraded according to the data packets; wherein the energy storage system includes multiple devices to be upgraded, each device to be upgraded has an address code, and any two devices to be upgraded have different address codes. The technical solution of this embodiment solves the current problem of not being able to remotely upgrade energy storage devices, enabling remote software upgrades of various devices in the energy storage system, improving the efficiency and convenience of software upgrades, reducing labor costs, and ensuring the stability of the upgrade process and equipment safety by determining whether to send an upgrade request and stop operation based on the operating condition, while minimizing losses due to charging and discharging stoppages.

[0087] In a specific example of an energy storage system upgrade, the energy storage system upgrade diagram can be as follows: Figure 5 As shown, the energy storage system includes an EMS, PCS, BCU, BMU, switch, serial server, electricity meter, air conditioner, and water immersion sensor. The cloud platform communicates with the local EMS of the energy storage system via the MQTT protocol, transmitting data packets and software upgrade packages. The EMS receives the software upgrade package from the cloud platform and forwards it to the PCS, BCU, and serial server via the switch, relying on LAN communication. The PCS, BCU, and serial server need to be configured with different IP addresses to upgrade them. Software upgrades for the electricity meter, air conditioner, and water immersion sensor require configuring different ports on the serial server for RS-485 communication. The software upgrade is then transmitted to these devices via RS-485, thus upgrading these three devices as well. Software upgrades for the BMU (Battery Unit Module) require the BCU to transmit the software upgrade package to the BMU via CAN, thereby upgrading the BMU's software.

[0088] like Figure 6 The diagram illustrates the scenario where multiple energy storage systems use a single EMS, meaning that multiple energy storage systems are associated with the same EMS. In this case, an additional switch is needed to forward information.

[0089] like Figure 7As shown, when the cloud platform determines that a remote software upgrade is needed based on the controller, it loads the software upgrade package and then performs the upgrade. The status can be viewed during and after the upgrade process, including start upgrade, upgrade in progress, upgrade successful, and upgrade failed. It can monitor each energy storage device during the upgrade process.

[0090] like Figure 8 As shown, the upgrade process for Level 1 equipment is as follows: After the cloud platform detects an upgrade request, it first checks the integrity of the data packet. If the data is complete, the cloud platform sends the data packet to the EMS via 4G. The EMS receives the data packet from the cloud platform locally in the energy storage system cabinet via 4G. After receiving the data packet, the EMS first checks the integrity of the data packet. After identifying that the data packet is complete, it reads the address of the target energy storage device. If the address is the address of the Level 1 device, the backup area upgrade data packet is loaded. After successful loading, the running storage area software is replaced.

[0091] like Figure 9 As shown, the upgrade process for secondary devices is as follows: After the cloud platform detects an upgrade request, it first checks the integrity of the data packet. If the data is complete, the cloud platform sends the data packet to the EMS via 4G. The EMS receives the data packet from the cloud platform locally in the energy storage system cabinet via 4G. After receiving the data packet, the EMS first checks the integrity of the data packet. After identifying that the data packet is complete, it reads the address of the target energy storage device and obtains the address of the secondary device (PCS, BCU, electricity meter, air conditioner, water immersion). The EMS sends the data packet to the corresponding secondary device via communication. After receiving the data packet, the secondary device also needs to check the integrity of the data. If the data packet is complete, the secondary device loads the backup area upgrade data packet. After successful loading, it replaces the running storage area software.

[0092] like Figure 10 As shown, the upgrade process for the three energy storage devices is as follows: After the cloud platform detects an upgrade request, it first checks the integrity of the data packet. If the data is complete, the cloud platform sends the data packet to the EMS via 4G. The EMS receives the data packet from the cloud platform locally in the energy storage system cabinet via 4G. After receiving the data packet, the EMS first checks the integrity of the data packet. After identifying that the data packet is complete, it reads the address of the target energy storage device and obtains that the address is the address of the third-level device (BMU). The EMS sends the data packet to the corresponding second-level device (BCU) via communication. After receiving the data packet, the second-level device also needs to check the integrity of the data. If the data packet is complete, the second-level device sends the data packet to the third-level device. After receiving the data packet, the third-level device first checks the integrity of the data packet. If the data packet integrity is normal, the third-level device loads the backup area upgrade data packet. After successful loading, it replaces the running storage area software.

[0093] Figure 11 This is a schematic diagram of the structure of an energy storage system upgrade device provided in an embodiment of the present invention. This embodiment is applicable to scenarios involving energy storage system upgrades. The device can be implemented in software and / or hardware and integrated into a computer device.

[0094] like Figure 11 As shown, the upgrade device for the energy storage system includes: a data packet acquisition module 310, an address code acquisition module 320, a data packet distribution module 330, and an upgrade module 340.

[0095] The system includes a data packet acquisition module 310, which sends an upgrade request to the cloud platform and receives data packets sent by the cloud platform to the energy storage system based on the upgrade request; an address code acquisition module 320, which parses the data packets to obtain the address codes of the devices to be upgraded; a data packet distribution module 330, which distributes data packets to the devices to be upgraded that have address codes; and an upgrade module 340, which upgrades the devices to be upgraded according to the data packets. The energy storage system includes multiple devices to be upgraded, each device having an address code, and the address codes of any two devices to be upgraded are different.

[0096] The technical solution of this invention involves sending an upgrade request to a cloud platform and receiving data packets sent by the cloud platform to the energy storage system based on the upgrade request; parsing the data packets to obtain the address codes of the devices to be upgraded; sending data packets to the devices with the address codes; and upgrading the devices according to the data packets. The energy storage system includes multiple devices to be upgraded, each with a unique address code, and the address codes of any two devices are different. This technical solution solves the current problem of the inability to remotely upgrade energy storage devices, enabling remote software upgrades for each device in the energy storage system, improving the efficiency and convenience of software upgrades, and reducing labor costs.

[0097] In one alternative implementation, the address code is of type Internet Protocol (IP) address.

[0098] In one optional implementation, the data packet acquisition module 310 is specifically used for:

[0099] Determine if the current equipment needs an upgrade; if so, determine if the energy storage system is currently in a valley period; if so, stop the charging and discharging of the energy storage system and send an upgrade request to the cloud platform; the operating conditions include peak, flat and valley periods.

[0100] In one optional implementation, the address code acquisition module 320 is specifically used for:

[0101] Parse the data packet to obtain the start code, binary upgrade data, discontinuity code, checksum, address code of the device to be upgraded, and end code.

[0102] In one alternative embodiment, the apparatus further includes:

[0103] The data packet verification module is used to verify the integrity of data packets;

[0104] The data packet verification module is specifically used for:

[0105] The binary upgrade data is processed by a preset verification function to obtain the information to be verified; the information to be verified is compared with the verification code; if the information to be verified and the verification code match, a data packet is sent to the device to be upgraded; if the information to be verified and the verification code do not match, data transmission to the device to be upgraded is stopped.

[0106] In one optional implementation, the device to be upgraded includes a Level 1 device, a Level 2 device, and a Level 3 device. The Level 1 device connects to one or more Level 2 devices, and each Level 2 device connects to one or more Level 3 devices. The data packet delivery module 330 is specifically used for:

[0107] The upgrade method determines the level of the device to be upgraded and sends data packets to the device level by level. According to the upgrade method, the step of sending data packets to the device level by level includes: if the device to be upgraded is a Level 1 device, then sending data packets to the device to be upgraded; if the device to be upgraded is a Level 2 device, then sending data packets to the corresponding Level 1 device, which in turn sends data packets to the device to be upgraded; if the device to be upgraded is a Level 3 device, then the data packets are transmitted sequentially through the corresponding Level 1 device and the corresponding Level 2 device, which in turn sends data packets to the device to be upgraded.

[0108] In one alternative implementation, each primary device, each secondary device, and each tertiary device performs a data packet integrity check before receiving the data packet.

[0109] In an optional implementation, the data packet delivery module 330 is further configured to:

[0110] Load the data package into the backup area of ​​the controller of the device to be upgraded; determine whether the data package loading was successful; if so, replace the original software in the controller's storage area.

[0111] The energy storage system upgrade device provided in the embodiments of the present invention can execute the energy storage system upgrade method provided in any embodiment of the present invention, and has the corresponding functional modules and beneficial effects of the method.

[0112] Figure 12 This is a schematic diagram of an energy storage system provided in an embodiment of the present invention.
