Description

Technical Field

[0001] The present invention relates to the technical field of energy storage system upgrading, and particularly to a method and device for upgrading an energy storage system. Background Art

[0002] An energy storage system is a device with functions of energy storage, energy conversion, and charging, and is widely used in new energy fields such as solar photovoltaic power generation and wind power generation. Among them, the energy storage system consists of multiple modules such as a main board, a BMS (Battery Management System), an inverter, and a PV (Photovoltaic). Most of the existing OTA (Over-The-Air) upgrade methods require the main board to receive and store the upgrade files of each module from the server and then send them to the module through serial port or CAN (Controller Area Network) communication.

[0003] With the increasing functions of the BMS, inverter, and PV, etc., this traditional method of saving and then sending all module upgrade files will cause the main board to consume a large part of the space for storing module upgrade files. The energy storage system is often located in an environment with poor network bandwidth. If a large amount of data upgrade files are transmitted at one time, it not only requires a long download time, resulting in an upgrade timeout, but also when an upgrade timeout or failure occurs, the entire upgrade file needs to be downloaded again. Repeated download timeouts not only waste time but also increase the number of erasures of the program memory, affecting the life of the program memory. Summary of the Invention

[0004] The present invention provides a method and device for upgrading an energy storage system, which can save the storage space and computing resources of the main board module, reduce network download resources, avoid repeated downloads when an upgrade timeout or failure occurs, reduce the number of erasures of the program memory of the main board module, and avoid affecting the service life of the program memory due to repeated download failures and repeated erasures.

The first upgrade sub - package is an upgrade sub - package selected from several reference upgrade packages and to be sent to the target energy storage module. The several reference upgrade packages are multiple upgrade packages obtained by subcontracting reference upgrade data. The reference upgrade data is the upgrade data required for upgrading the target energy storage module after triggering the selection of the target energy storage module for upgrade;

[0027] Embodiment 1

[0028] Figure 1 It is a flowchart of an energy storage system upgrade method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of upgrading each energy storage module in the energy storage system. This method can be executed by an energy storage system upgrade device, which can be implemented in the form of hardware and / or software, and the energy storage system upgrade device can be configured in a device. For example, the device can be a device with communication and computing capabilities such as a background server. As Figure 1 shown, the method includes:

[0029] S110. Obtain the first upgrade subpackage of the target energy storage module in the first acquisition process stage. The first upgrade subpackage is an upgrade subpackage selected from several reference upgrade packages and needs to be sent to the target energy storage module. The several reference upgrade packages are multiple upgrade packages obtained by subcontracting the reference upgrade data, and the reference upgrade data is the upgrade data required for upgrading the target energy storage module after triggering the selection of the target energy storage module for upgrade.

[0030] In this solution, the energy storage module is a module with specific functions in the energy storage system. Optionally, the energy storage module includes a BMS module, an inverter module, and a photovoltaic module. The BMS module is mainly used to manage and protect the battery module; the function of the inverter module is to convert the direct current output by the battery module into alternating current; the photovoltaic module is used to convert solar energy into electrical energy and provide electrical energy input for the energy storage system.

[0031] In this embodiment, the energy storage system includes a main board module and at least one energy storage module. The main board module is used to assist the energy storage system in realizing various functions, and a network component is configured on the main board module. Among them, the network component can be a Bluetooth WIFI component. The BMS module, the inverter module, and the photovoltaic module communicate with the main board module through a serial port or CAN, and the BMS module, the inverter module, and the photovoltaic module need to perform OTA firmware upgrade through the main board module.

[0032] Among them, the target energy storage module is the energy storage module that needs to be upgraded among at least one energy storage module. For example, the target energy storage module can be a BMS module, an inverter module, or a BMS module and an inverter module, etc. The target energy storage module can be selected from at least one energy storage module through a triggering operation on the device side. Among them, the device side can be a mobile phone side, a computer side, etc.

[0033] In this solution, several reference upgrade packages are obtained by subcontracting the upgrade data required for upgrading the target energy storage module, and an upgrade subpackage selected from the several reference upgrade packages and needed to be sent to the target energy storage module is used as the first upgrade subpackage.

[0034] Among them, the first acquisition process stage is the stage of obtaining the first upgrade subpackage from several reference upgrade packages.

[0035] Specifically, Figure 2 is the flowchart of the energy storage system upgrade process provided in Embodiment 1 of this application, as Figure 2As shown, in the first acquisition process stage, the main board module receives the first upgrade sub-package download link sent by the server, and uses the HyperText Transfer Protocol to obtain the first upgrade sub-package of the target energy storage module from the first upgrade sub-package download link. Among them, the server is communicatively connected to the main board module in the energy storage system. The HyperText Transfer Protocol (http) is an application layer protocol used to transfer hypertext on the network.

[0036] In this solution, when there are multiple target energy storage modules, in the first acquisition process stage, the main board module receives multiple first upgrade sub-package download links sent by the server, and uses the HyperText Transfer Protocol to obtain the first upgrade sub-packages of the corresponding target energy storage modules according to the multiple first upgrade sub-package download links. For example, if the target energy storage modules include energy storage module A, energy storage module B, and energy storage module C, and the first upgrade sub-package of energy storage module A is A1, the first upgrade sub-package of energy storage module B is B1, and the first upgrade sub-package of energy storage module C is C1. In the first acquisition process stage, the main board module receives the A1 download link, B1 download link, and C1 download link sent by the server, and then obtains the first upgrade sub-package A1 of energy storage module A, the first upgrade sub-package B1 of energy storage module B, and the first upgrade sub-package C1 of energy storage module C from these links respectively through the HyperText Transfer Protocol.

[0037] S120. Forward the first upgrade sub-package to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-package.

[0038] In this solution, as Figure 2 shown, the main board module forwards the first upgrade sub-package to the target energy storage module. After receiving the first upgrade sub-package, the target energy storage module upgrades the energy storage module based on the first upgrade sub-package.

[0039] Optionally, forwarding the first upgrade sub-package to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-package includes:

[0040] Forward the first upgrade sub-package to the target energy storage module so that the target energy storage module writes the attribute information of the first upgrade sub-package into a preset storage space; the attribute information of the first upgrade sub-package includes the upgrade package version information, upgrade package serial number, and upgrade package size corresponding to the first upgrade sub-package.

[0041] Among them, the upgrade package version information is the relevant content used to identify the upgrade package version; the upgrade package serial number is a number used to identify the upgrade package; the upgrade package size refers to the storage space size occupied by the upgrade package.

[0042] In this embodiment, the preset storage space refers to the storage space in the Flash memory.

[0043] In this solution, as Figure 2 shown, the main board module forwards the first upgrade sub-packet to the target energy storage module. After receiving the first upgrade sub-packet, the target energy storage module upgrades the energy storage module based on the first upgrade sub-packet, and stores the upgrade package version information, upgrade package serial number, and upgrade package size corresponding to the first upgrade sub-packet in the preset storage space.

[0044] By storing the upgrade package version information, upgrade package serial number, and upgrade package size corresponding to the first upgrade sub-packet in the preset storage space of the target energy storage module, the storage space of the main board module can be saved.

[0045] S130. Receive the second upgrade sub-packet request returned by the target energy storage module for continuing to obtain the second upgrade sub-packet from the several reference upgrade packets according to the second upgrade sub-packet request after entering the second acquisition process stage. The second acquisition process stage is the acquisition process stage that needs to continue to obtain the next upgrade packet from the several reference upgrade packets after obtaining the first upgrade sub-packet in the first acquisition process stage.

[0046] In this embodiment, the second upgrade sub-packet request refers to the request sent by the target energy storage module to obtain the second upgrade sub-packet. Among them, the second upgrade sub-packet includes other upgrade packets in the several reference upgrade packets except the first upgrade sub-packet.

[0047] In this solution, the second acquisition process stage is the acquisition process stage that needs to continue to obtain the next upgrade packet from the several reference upgrade packets after obtaining the first upgrade sub-packet in the first acquisition process stage.

[0048] Specifically, in the second acquisition stage, the main board module receives the second upgrade sub-packet request returned by the target energy storage module and forwards the second upgrade sub-packet request to the server. In response to the second upgrade sub-packet request, the server issues a second upgrade sub-packet download link. The main board module receives the second upgrade sub-packet download link issued by the server and obtains the second upgrade sub-packet of the target energy storage module from the second upgrade sub-packet download link using the Hypertext Transfer Protocol.

[0049] Further, the main board module forwards the second upgrade sub-packet to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the second upgrade sub-packet and writes the attribute information of the second upgrade sub-packet into the preset storage space.

[0050] Further, as Figure 2As shown, the main board module continues to receive the second upgrade sub-packet request returned by the target energy storage module and forwards the second upgrade sub-packet request to the server. In response to the second upgrade sub-packet request, the server issues a second upgrade sub-packet download link. The main board module receives the second upgrade sub-packet download link issued by the server and uses the Hypertext Transfer Protocol to obtain the second upgrade sub-packet of the target energy storage module from the second upgrade sub-packet download link. The main board module forwards the second upgrade sub-packet to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the second upgrade sub-packet and writes the attribute information of the second upgrade sub-packet into the preset storage space. Repeat the above steps for downloading and writing until a message indicating the completion of the upgrade sent by the target energy storage module is received. At this time, the target energy storage module has received all the upgrade packages.

[0051] In this embodiment, as Figure 2 shown, after receiving the first upgrade sub-packet and the second upgrade sub-packet, the target energy storage module uses the differential algorithm to calculate the first upgrade sub-packet and the second upgrade sub-packet to obtain the complete reference upgrade data. At this time, the target energy storage module sends a message indicating the completion of the upgrade to the main board module and exits the upgrade state. After receiving the message indicating the completion of the upgrade, the main board module exits the upgrade state. Among them, the differential algorithm finds the different parts of the data between the two upgrade packages, and then based on these different data and the characteristics of the two upgrade packages respectively, through a series of calculation and integration operations, finally obtains a complete reference upgrade data. The differential algorithm includes the bsdiff algorithm.

[0052] In this solution, when there are multiple target energy storage modules, in the second acquisition process stage, the main board module receives multiple second upgrade subpackage download links sent by the server, and uses the Hypertext Transfer Protocol to obtain the second upgrade subpackages of the corresponding target energy storage modules according to the multiple second upgrade subpackage download links. For example, if the target energy storage modules include energy storage module A, energy storage module B, and energy storage module C, and the second upgrade subpackages of energy storage module A are A2 and A3, the second upgrade subpackages of energy storage module B are B2 and B3, and the second upgrade subpackages of energy storage module C are C2 and C3. In the second acquisition process stage, the main board module receives the A2 download link, B2 download link, and C2 download link sent by the server, and respectively obtains the second upgrade subpackage A2 of energy storage module A, the second upgrade subpackage B2 of energy storage module B, and the second upgrade subpackage C2 of energy storage module C from these links through the Hypertext Transfer Protocol. Then the main board module continues to receive the second upgrade subpackage requests returned by the target energy storage modules and forwards the second upgrade subpackage requests to the server. The server responds to the second upgrade subpackage requests and sends the second upgrade subpackage download links. The main board module receives the A3 download link, B3 download link, and C3 download link sent by the server, and again respectively obtains the second upgrade subpackage A3 of energy storage module A, the second upgrade subpackage B3 of energy storage module B, and the second upgrade subpackage C3 of energy storage module C from these links through the Hypertext Transfer Protocol.

[0053] The technical solution of the embodiment of the present invention is to obtain the first upgrade subpackage of the target energy storage module in the first acquisition process stage, and then forward the first upgrade subpackage to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade subpackage. Receive the second upgrade subpackage requests returned by the target energy storage modules for continuing to obtain the second upgrade subpackages from several reference upgrade packages according to the second upgrade subpackage requests after entering the second acquisition process stage. By implementing this technical solution, through the upgrade method of subpackage forwarding, the main board module acts as a role of transferring upgrade packages and upgrade states, does not save the upgrade files of all energy storage modules, saves the storage resources and computing resources of the main board module. It can also reduce the network download resources of the main board module, avoid repeated downloads in case of upgrade timeouts or failures, reduce the number of erasures of the program memory, and avoid affecting the service life of the program memory due to repeated download failures and repeated erasures.

[0054] Embodiment 2

[0055] Figure 3 FIG. is a schematic diagram of the upgrade process of an energy storage system provided by Embodiment 2 of the present invention. The relationship between this embodiment and the above embodiment is a detailed description of the upgrade process of the energy storage system. As Figure 3 shown, the method includes:

[0056] S310. In response to the first message sent by the server, configure the main board module to the upgrade state, and based on the first message, control the target energy storage module to be configured to the upgrade state; the first message includes the identifier of the target energy storage module and the target upgrade version information; the identifier of the target energy storage module is used to indicate the energy storage module that needs to be upgraded among at least one energy storage module; the target upgrade version information is the version information of the upgrade package that the target energy storage module is about to upgrade and deploy; the server is communicatively connected to the main board module in the energy storage system.

[0057] Among them, the first message is used to instruct the main board module and the target energy storage module to be configured to the upgrade state. The first message includes the identifier of the target energy storage module and the target upgrade version information; the identifier of the target energy storage module is used to indicate the energy storage module that needs to be upgraded among at least one energy storage module; the target upgrade version information is the version information of the upgrade package that the target energy storage module is about to upgrade and deploy.

[0058] Specifically, as Figure 2 shown, in response to the trigger selection operation of the device side, the server sends the first message to the main board module. The main board module is configured to the upgrade state in response to the first message sent by the server. And forward the first message to the target energy storage module, so that the target energy storage module is configured to the upgrade state. Among them, the device side can be a mobile phone side, a computer side, etc. The trigger selection operation can include a click operation, a drop-down selection operation, a touch operation, an input operation, etc.

[0059] Optionally, controlling the target energy storage module to be configured to the upgrade state based on the first message includes:

[0060] Determine the target energy storage module from at least one energy storage module by parsing the first message, and directionally forward the first message to the target energy storage module, so that the target energy storage module enters the upgrade state;

[0061] Or, forward the first message to each energy storage module among at least one energy storage module, so that the target energy storage module indicated by the first message among the at least one energy storage module enters the upgrade state after parsing the first message.

[0062] In this solution, the main board module parses the first message to obtain the identifier of the target energy storage module in the first message, and determines the target energy storage module from at least one energy storage module based on the identifier of the target energy storage module. Then forward the first message to the target energy storage module, so that the target energy storage module is configured to the upgrade state based on the first message.

[0063] Determining the target energy storage module by parsing the first message can achieve the directional forwarding of the first message, thereby improving the message transmission efficiency and enhancing the security of message transmission.

[0064] In this embodiment, the main board module forwards the first message to each energy storage module in at least one energy storage module. After receiving the first message, each energy storage module parses the first message to obtain the identifier of the target energy storage module in the first message, determines the target energy storage module based on the identifier of the target energy storage module, and configures it to the upgrade state. For example, assume that there are multiple energy storage modules in the energy storage system, namely energy storage module A, energy storage module B, and energy storage module C, and the identifier of the target energy storage module is A, then energy storage module A is determined as the target energy storage module.

[0065] By forwarding the first message and parsing the first message based on each energy storage module, the computing resources of the main board module can be saved.

[0066] S320. Obtain a first upgrade sub-packet of the target energy storage module in the first acquisition process stage. The first upgrade sub-packet is an upgrade sub-packet selected from several reference upgrade packets that needs to be sent to the target energy storage module. The several reference upgrade packets are multiple upgrade packets obtained by sub-packet processing of reference upgrade data. The reference upgrade data is the upgrade data required for upgrading the target energy storage module after triggering the selection of the target energy storage module for upgrade.

[0067] S330. Forward the first upgrade sub-packet to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-packet.

[0068] S340. Receive a second upgrade sub-packet request returned by the target energy storage module for continuing to obtain a second upgrade sub-packet from the several reference upgrade packets according to the second upgrade sub-packet request after entering the second acquisition process stage. The second acquisition process stage is the acquisition process stage that needs to continue to obtain the next upgrade sub-packet from the several reference upgrade packets after obtaining the first upgrade sub-packet in the first acquisition process stage.

[0069] The technical solution of the embodiment of the present invention configures the main board module to the upgrade state by responding to the first message sent by the server, and controls the target energy storage module to be configured to the upgrade state based on the first message. Then obtain the first upgrade sub-packet of the target energy storage module in the first acquisition process stage, and forward the first upgrade sub-packet to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-packet. Receive the second upgrade sub-packet request returned by the target energy storage module for continuing to obtain the second upgrade sub-packet from the several reference upgrade packets according to the second upgrade sub-packet request after entering the second acquisition process stage. By executing this technical solution, through the upgrade method of sub-packet forwarding, the main board module acts as a role of transferring an upgrade packet and an upgrade state, does not save the upgrade files of all energy storage modules, saves the storage space, computing resources of the main board module, and reduces the network download resources of the main board module.

[0070] Embodiment III

[0071] Figure 4 As shown in the schematic diagram of a method for upgrading an energy storage system provided in Embodiment III of the present invention, the relationship between this embodiment and the above embodiments is a detailed description of the energy storage system upgrade process. As Figure 4 shown, the method includes:

[0072] S410. Receive a second message sent by the target energy storage module and send the second message to the server, so that the server determines the reference upgrade data according to the second message; the second message includes the attribute information of the third upgrade sub-packet in the target energy storage module, and the third upgrade sub-packet is the upgrade packet that has been deployed in the target energy storage module during the previous upgrade before triggering the selection of the target energy storage module for upgrade, and the attribute information of the third upgrade sub-packet includes the upgrade packet version information, upgrade packet serial number, and upgrade packet size corresponding to the third upgrade sub-packet.

[0073] Among them, the second message is used to instruct the server to determine the reference upgrade data. The second message includes the attribute information of the third upgrade sub-packet in the target energy storage module. The third upgrade sub-packet is the upgrade packet that has been deployed in the target energy storage module during the previous upgrade before triggering the selection of the target energy storage module for upgrade. The attribute information of the third upgrade sub-packet includes the upgrade packet version information, upgrade packet serial number, and upgrade packet size corresponding to the third upgrade sub-packet.

[0074] In this embodiment, the reference upgrade data is the upgrade data required for upgrading the target energy storage module after triggering the selection of the target energy storage module for upgrade.

[0075] Specifically, as Figure 2 shown, after the target energy storage module is configured to the upgrade state, it sends a second message to the main board module. The main board module receives the second message sent by the target energy storage module and sends the second message to the server, so that the server determines the reference upgrade data according to the second message.

[0076] Furthermore, the server can determine the reference upgrade data based on the upgrade packet version information, upgrade packet serial number, and upgrade packet size corresponding to the third upgrade sub-packet; the server can also determine the reference upgrade data based on the upgrade packet version information corresponding to the third upgrade sub-packet.

[0077] Optionally, receiving the second message sent by the target energy storage module and sending the second message to the server, so that the server determines the reference upgrade data according to the second message, includes:

[0078] Receive the second message sent by the target energy storage module and send the second message to the server, so that when the target upgrade version information is consistent with the upgrade package version information corresponding to the third upgrade subpackage, the server extracts reference upgrade data from the initial upgrade data according to the upgrade package serial number and upgrade package size corresponding to the third upgrade subpackage. The initial upgrade data is the upgrade data obtained by performing differential processing on the upgrade file corresponding to the target upgrade version information and the upgrade file corresponding to the upgrade package version information corresponding to the third upgrade subpackage.

[0079] In this solution, as Figure 2 shown, after the energy storage system connects to the message transmission protocol for power distribution network and reports the upgrade package version information corresponding to the third upgrade subpackage of each energy storage module to the server, the server compares the difference between the upgrade file corresponding to the target upgrade version information and the upgrade file corresponding to the upgrade package version information corresponding to the third upgrade subpackage through the differential algorithm to generate the initial upgrade data. Among them, the message transmission protocol includes MQTT (Message Queuing Telemetry Transport), and MQTT is a lightweight message transmission protocol based on the publish or subscribe mode, mainly used for communication between Internet of Things devices and between devices and servers.

[0080] Further, after the server receives the second message, it determines whether the target upgrade version information is consistent with the upgrade package version information corresponding to the third upgrade subpackage in the target energy storage module included in the second message. If they are consistent, it means that some content in the target energy storage module was not upgraded during the previous upgrade process. Then, multiply the upgrade package serial number and upgrade package size corresponding to the third upgrade subpackage to calculate the first upgrade data, and then use the differential algorithm to compare the difference between the initial upgrade data and the first upgrade data to determine the reference upgrade data.

[0081] By judging the target upgrade version information and the upgrade package version information corresponding to the third upgrade subpackage in the target energy storage module included in the second message and extracting the reference upgrade data from the initial upgrade data, it can avoid repeated downloads after upgrade interruption timeout or failure, and reduce the space for parameter upgrade data transmission and storage.

[0082] Optionally, receiving the second message sent by the target energy storage module and sending the second message to the server, so that the server determines the reference upgrade data according to the second message, further includes:

[0083] Receive the second message sent by the target energy storage module and send the second message to the server, so that when the target upgrade version information is inconsistent with the upgrade package version information corresponding to the third upgrade subpackage, the server determines the initial upgrade data as the reference upgrade data. The initial upgrade data is the upgrade data obtained by performing differential processing on the upgrade file corresponding to the target upgrade version information and the upgrade file corresponding to the upgrade package version information corresponding to the third upgrade subpackage.

[0084] Further, after receiving the second message, the server determines whether the target upgrade version information is consistent with the upgrade package version information corresponding to the third upgrade subpackage included in the second message in the target energy storage module. If not, it indicates that all the content to be upgraded has been completed during the previous upgrade of the target energy storage module, and there is no remaining part that has not been upgraded. Then, the initial upgrade data is determined as the reference upgrade data.

[0085] By judging the target upgrade version information and the upgrade package version information corresponding to the third upgrade subpackage included in the second message, and determining the initial upgrade data as the reference upgrade data, the energy storage module can be upgraded based on the reference upgrade data.

[0086] S420. In response to the data volume of the reference upgrade data sent by the server, determine the reference upgrade package size according to the network information and send the reference upgrade package size to the server, so that the server performs subpackage processing on the reference upgrade data according to the reference upgrade package size to determine several reference upgrade packages; the reference upgrade package size is the size of several data blocks obtained by splitting the reference upgrade data; the network information is determined based on the network components configured on the main board module.

[0087] Among them, the network information includes network speed and network signal strength. The network speed and network signal strength are obtained based on the instructions of the network components configured on the main board.

[0088] In this solution, the reference upgrade package size is the size of several data blocks obtained by splitting the reference upgrade data.

[0089] In this embodiment, the data volume of the reference upgrade data can be represented by the byte size. As Figure 2 shown, after the server determines the reference upgrade data according to the second message, it sends the data volume of the reference upgrade data to the main board module. Based on the maximum calculated space, the main board module, in response to the data volume of the reference upgrade data sent by the server, determines the reference upgrade package size according to the network information.

[0090] In this solution, the size of the reference upgrade package can be determined according to the network speed and the network signal strength. For example, when the network speed of the motherboard module is fast and the network signal strength is large, a larger reference upgrade package size can be set.

[0091] Optionally, determining the size of the reference upgrade package according to network information includes:

[0092] Adjusting the size of the upgrade package corresponding to the third upgrade sub-package according to network information to determine the size of the reference upgrade package.

[0093] In this solution, when the target upgrade version information is consistent with the upgrade package version information corresponding to the third upgrade sub-package, at this time, the motherboard module adjusts the size of the upgrade package corresponding to the third upgrade sub-package according to network information to determine the size of the reference upgrade package. Specifically, increase or decrease the size of the upgrade package corresponding to the third upgrade sub-package according to network information.

[0094] Adjusting the size of the upgrade package through network speed and signal strength can perform few and efficient downloads when the network condition is good, and at the same time can avoid the situation of download failure when the network condition is poor, and perform effective downloads in multiple times, improving the download efficiency of the upgrade package.

[0095] Optionally, determining the size of the reference upgrade package according to network information further includes:

[0096] Determining the reference upgrade package size corresponding to the network information from the pre-determined matching relationship between network information and upgrade package size according to the network information.

[0097] In this embodiment, the matching relationship between network information and upgrade package size can be obtained by training network information and upgrade package size using a deep learning model.

[0098] In this solution, when the target upgrade version information is inconsistent with the upgrade package version information corresponding to the third upgrade sub-package, at this time, the motherboard module determines the reference upgrade package size corresponding to the network information from the pre-determined matching relationship between network information and upgrade package size.

[0099] Adjusting the size of the upgrade package through network speed and signal strength can perform few and efficient downloads when the network condition is good, and at the same time can avoid the situation of download failure when the network condition is poor, and perform effective downloads in multiple times, improving the download efficiency of the upgrade package.

[0100] In this solution, after responding to the first message sent by the server, configuring the motherboard module to the upgrade state, and controlling the target energy storage module to be configured to the upgrade state based on the first message, steps S410 - S420 can be executed.

[0101] S430. Obtain the first upgrade sub-package of the target energy storage module in the first acquisition process stage. The first upgrade sub-package is one upgrade sub-package selected from several reference upgrade packages that needs to be sent to the target energy storage module. The several reference upgrade packages are multiple upgrade packages obtained by subcontracting the reference upgrade data, and the reference upgrade data is the upgrade data required for upgrading the target energy storage module after triggering the selection of the target energy storage module for upgrading.

[0102] S440. Forward the first upgrade sub-package to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-package.

[0103] S450. Receive the second upgrade sub-package request returned by the target energy storage module for continuing to obtain the second upgrade sub-package from the several reference upgrade packages according to the second upgrade sub-package request after entering the second acquisition process stage. The second acquisition process stage is the acquisition process stage that needs to continue to obtain the next upgrade sub-package from the several reference upgrade packages after obtaining the first upgrade sub-package in the first acquisition process stage.

[0104] The technical solution of the embodiment of the present invention is to receive the second message sent by the target energy storage module and send the second message to the server so that the server determines the reference upgrade data according to the second message. In response to the data volume of the reference upgrade data sent by the server, determine the reference upgrade package size according to the network information and send the reference upgrade package size to the server so that the server subcontracts the reference upgrade data according to the reference upgrade package size to determine several reference upgrade packages. Then obtain the first upgrade sub-package of the target energy storage module in the first acquisition process stage and forward the first upgrade sub-package to the target energy storage module so that the target energy storage module upgrades the energy storage module based on the first upgrade sub-package. Receive the second upgrade sub-package request returned by the target energy storage module for continuing to obtain the second upgrade sub-package from the several reference upgrade packages according to the second upgrade sub-package request after entering the second acquisition process stage. By implementing this technical solution, through the upgrade method of subcontracting and forwarding, the main board module acts as a role of transferring one upgrade package and the upgrade status, does not save the upgrade files of all energy storage modules, saves the storage space, computing resources of the main board module, and reduces the network download resources of the main board module. Adjust the upgrade package size according to the network speed and signal strength, which can perform fewer and more efficient downloads when the network condition is good, and at the same time can avoid the situation of download failure when the network condition is poor, and perform effective downloads in multiple times, improving the download efficiency of the upgrade package.
