Description

Technical Field

[0001] This disclosure relates to, but is not limited to, the field of energy Internet of Things technology, and more specifically, to a remote upgrade method, a home energy storage device, a mobile terminal, and a cloud server. Background Technology

[0002] With the popularization of new energy technologies, the user base of home mobile energy storage products has grown rapidly. Modern home mobile energy storage products typically integrate multiple functional modules (such as BMS battery management system, inverter module, etc.), each with independent firmware.

[0003] Firmware upgrades are crucial for addressing potential security vulnerabilities in devices after they leave the factory, adjusting operating parameters, and expanding new features. Traditional OTA (Over-The-Air) upgrades heavily rely on the device's own wide-area network connectivity, such as Wi-Fi. However, many home portable energy storage products, due to cost control, power consumption limitations, or design simplification considerations, do not have Wi-Fi modules. These products typically only have short-range, low-power communication capabilities such as Bluetooth, and cannot directly connect to the internet, thus excluding them from the traditional OTA upgrade system.

[0004] Therefore, energy storage equipment manufacturers with different models and configurations (with or without Wi-Fi) of their product lines urgently need a unified upgrade management technology solution that can cover all home mobile energy storage products, realize centralized management and release of upgrade strategies, and simplify operation and maintenance complexity.

If the device is determined to have WAN connectivity, then home network configuration information and home account identification information are sent to the device to enable the device to perform an autonomous remote upgrade process; if the device is determined not to have WAN connectivity, then it acts as a communication proxy between the device and the cloud server to perform a proxy upgrade process.

[0007] This disclosure provides a remote upgrade method applied to a cloud server, including: Receive a user registration request from a mobile terminal and register a family account for the user; wherein the user is a user of a home energy storage device; Obtain the device's WAN connectivity information, and depending on whether the device has WAN connectivity, select whether to complete the device registration, family account binding, and remote upgrade service subscription directly or indirectly through the mobile terminal as a communication proxy between the device and the cloud server. When firmware upgrades are detected on the device, a batch upgrade task is generated and an upgrade notification is sent to the mobile terminal corresponding to the device. After receiving the user authorization response from the mobile terminal in response to the upgrade notification, the corresponding upgrade method is selected according to the device's WAN connectivity: if the device has WAN connectivity, upgrade instructions are sent directly to the device in sequence according to the batch upgrade task, and the upgrade result information fed back by the device is received; if the device does not have WAN connectivity, upgrade instructions are sent to the mobile terminal in sequence according to the batch upgrade task, and the upgrade result information forwarded by the mobile terminal from the device is received.

Step S20: If it is determined that the device has wide area network (WAN) connectivity, then an autonomous remote upgrade process is executed; if it is determined that the device does not have WAN connectivity, then a remote upgrade process is completed using a mobile terminal; wherein, the mobile terminal acts as a communication proxy between the device and the cloud server.

[0019] In this embodiment of the remote upgrade method, the home energy storage device acquires device information and determines whether it has wide area network (WAN) connectivity based on the information. If the device is determined to have WAN connectivity, an autonomous remote upgrade process is executed. If the device is determined not to have WAN connectivity, a mobile terminal is used to complete the remote upgrade process. The mobile terminal acts as a communication proxy between the device and the cloud server. This remote upgrade method universalizes the remote upgrade capability of home energy storage devices, enabling home energy storage devices with heterogeneous underlying communication networks to be included in a unified remote upgrade management system.

[0020] In one exemplary embodiment of this disclosure, the mobile terminal includes: mobile phone, tablet computer, laptop computer, e-reader, wearable smart device, etc.

[0021] In an exemplary embodiment of this disclosure, determining whether the device has wide area network connectivity based on the information includes: The hardware configuration information in the information is analyzed; if the hardware configuration information indicates that the device integrates at least one of a wireless LAN access module or a cellular mobile communication module, the device is determined to have WAN connectivity capability; otherwise, the device is determined not to have WAN connectivity capability. The wireless LAN access module is mainly used to connect to local wireless networks (such as Wi-Fi in homes, offices, or public places), and ultimately accesses the WAN (Internet) through the router of that network. The cellular mobile communication module can directly access the cellular network of mobile operators (such as 4G, 5G), thereby accessing the WAN anytime, anywhere.

[0022] In an exemplary embodiment of this disclosure, performing an autonomous remote upgrade process includes executing the following steps S1-S6: Step S1: Establish a short-range wireless communication connection with the mobile terminal and send device information to the mobile terminal; the information includes device identification information and hardware configuration information; receive home network configuration information and home account identification information returned by the mobile terminal; Step S2: Initiate a device registration request to the cloud server and bind the device to the family account.

[0023] Steps S1 and S2 are initialization steps performed when the device first accesses the network; steps S3 to S6 are upgrade execution steps that are repeatedly performed in response to various upgrade tasks issued by the cloud server during the device's lifecycle.

[0024] In one exemplary embodiment of this disclosure, the upgrade result information includes: an indication of successful upgrade and the updated firmware version number, or an indication of failed upgrade and a failure error code.

[0025] In an exemplary embodiment of this disclosure, the hardware module includes at least one of the following: a battery management system, an inverter module, a communication controller module, an energy management unit, and a safety protection module.

[0026] The battery management system and inverter module are the core hardware modules of a home energy storage device. They are responsible for the safe management and control of energy storage and the intelligent conversion of AC and DC power, respectively. The stability and performance of their firmware directly determine the efficiency, safety, and lifespan of the entire energy storage system. Other hardware modules, such as the communication controller module, energy management unit, and safety protection module, constitute the key auxiliary subsystems of the device. They are responsible for reliable network communication between the device and the cloud / local area network, intelligent scheduling of charging and discharging based on power load and electricity price signals, and real-time monitoring and protection against abnormal conditions such as overvoltage, overcurrent, and overtemperature.

[0027] In an exemplary embodiment of this disclosure, the device performs an autonomous remote upgrade process, including: When the remote upgrade task message contains multiple independent upgrade items, each independent upgrade item is upgraded sequentially; after completing the upgrade process for any independent upgrade item, the upgrade result information for that item is fed back to the cloud server.

[0028] In an exemplary embodiment of this disclosure, a remote upgrade process is completed using a mobile terminal, including performing the following steps S1-S3: Step S1: Establish a short-range wireless communication connection with the mobile terminal and send device information to the mobile terminal; wherein, the mobile terminal acts as the registration agent of the device, initiates a device registration request to the cloud server and binds the device to the corresponding family account, establishing a logical subscription relationship between the device and the remote upgrade service; the device information includes the device's identification information and hardware configuration information; the device registration request carries the device's identification information and the family account's identification information; Step S2: Receive the verified firmware file sent by the mobile terminal via a short-range wireless communication connection, and burn it to the target hardware module to perform a firmware upgrade; wherein, after receiving the remote upgrade task notification pushed by the cloud server according to the logical subscription relationship, the mobile terminal parses the notification to obtain the description information and verification credentials of the target firmware file, downloads the corresponding new version firmware file from the cloud server according to the description information, performs integrity verification and security verification on the downloaded firmware file using the verification credentials, and only transmits the verified firmware file to the device via a short-range wireless communication connection after successful verification; Step S3: Send an upgrade result message to the mobile terminal, and the mobile terminal forwards the upgrade result message to the cloud server; Step S1 is the initialization step executed when the device first accesses the network; steps S2 to S3 are upgrade execution steps that are repeatedly executed in response to various upgrade tasks issued by the cloud server during the device's life cycle.

[0029] In an exemplary embodiment of this disclosure, a remote upgrade process is completed using a mobile terminal, including: When the upgrade task message contains multiple independent upgrade items, the mobile terminal performs the following processes for each independent upgrade item in sequence: parsing the upgrade item, downloading the corresponding firmware file, verifying the downloaded file, and transmitting the verified file to the device. The device sequentially performs upgrade operations based on the received firmware files; After completing the upgrade operation for any independent upgrade item, the device sends an upgrade result message for that item to the mobile terminal, and the mobile terminal forwards the upgrade result message to the cloud server.

[0030] In an exemplary embodiment of this disclosure, the instructions for each independent upgrade item include at least one of the following information: firmware version number, download address of firmware file, integrity verification information (e.g., MD5 code), upgrade text, and risk warning information before upgrade.

[0031] like Figure 2 As shown, one embodiment of this disclosure provides a remote upgrade method applied to a mobile terminal, including: Step S10: Send a user registration request to the cloud server to obtain the family account assigned by the cloud server to the user of the home energy storage device; Step S20: Establish a short-range wireless communication connection with the home energy storage device, obtain information about the device, and determine whether the device has wide area network connectivity based on the information about the device. Step S30: If it is determined that the device has WAN connectivity, then send home network configuration information and home account identification information to the device to enable the device to perform an autonomous remote upgrade process; if it is determined that the device does not have WAN connectivity, then act as a communication proxy between the device and the cloud server to perform a proxy upgrade process.

[0032] In this embodiment of the remote upgrade method, the mobile terminal sends a user registration request to the cloud server to obtain a family account assigned by the cloud server to the user of the home energy storage device; establishes a short-range wireless communication connection with the home energy storage device, obtains the device's information, and determines whether the device has wide area network (WAN) connectivity based on the device information; if the device has WAN connectivity, the mobile terminal sends home network configuration information and family account identification information to the device, enabling the device to autonomously complete registration and binding on the cloud; if the device does not have WAN connectivity, the mobile terminal acts as a communication proxy between the device and the cloud server, executing a proxy upgrade process. This remote upgrade method adaptively adapts to two remote upgrade modes for home energy storage devices on the mobile terminal side. On the one hand, it enables high-end home energy storage devices with built-in WAN connectivity to conveniently and autonomously complete the entire upgrade process; on the other hand, it enables low-complexity, low-cost home energy storage devices without WAN connectivity to obtain the same remotely manageable upgrade capabilities as high-end devices through the proxy capability of the mobile terminal. This fundamentally breaks the limitation of device hardware cost on upgradeability, greatly expands the physical form and cost boundaries of home energy storage devices that can support remote upgrades, and provides a convenient and reliable solution for the large-scale deployment and operation and maintenance of IoT devices.

[0033] In one exemplary embodiment of this disclosure, the mobile terminal includes: mobile phone, tablet computer, laptop computer, e-reader, wearable smart device, etc.

[0034] In an exemplary embodiment of this disclosure, determining whether the device has wide area network connectivity based on the device's information includes: The hardware configuration information in the device information is analyzed; if the hardware configuration information indicates that the device integrates at least one of a wireless local area network access module or a cellular mobile communication module, the device is determined to have wide area network connectivity capability; otherwise, the device is determined not to have wide area network connectivity capability.

[0035] In an exemplary embodiment of this disclosure, the agent upgrade process includes: registration and binding, establishing a subscription relationship, obtaining upgrade files and transmitting them to the device, and receiving upgrade result information from the device and transmitting it to the cloud server.

[0036] In an exemplary embodiment of this disclosure, home network configuration information and home account identification information are sent to the device to enable the device to perform an autonomous remote upgrade process, including performing the following steps S1-S4: Step S1: Send home network configuration information and home account identification information to the device so that the device can use the information to complete cloud registration, account binding and MQTT service subscription; Step S2: Receive a batch upgrade task notification pushed by the cloud server based on the MQTT service subscribed to by the device, which contains an overview of at least one independent upgrade item; Step S3: Show the user the overview information in the batch upgrade task notification, and after obtaining unified authorization from the user, send an authorization confirmation to the cloud server so that the cloud server can send upgrade instructions for each independent upgrade item to the device in sequence. Step S4: Receive the upgrade result information of the device from the cloud server and present it to the user; Step S1 is the initialization step executed when the device first connects to the network; steps S2 to S4 are upgrade execution steps that are repeatedly executed in response to various remote upgrade tasks issued by the cloud server during the device's life cycle.

[0037] The overview information is user-friendly text explaining the content of this firmware upgrade. It is part of the user experience design and aims to inform users of the purpose and benefits of the upgrade in order to encourage users to authorize the upgrade.

[0038] In one exemplary embodiment of this disclosure, the upgrade result information includes: an indication of successful upgrade and the updated firmware version number, or an indication of failed upgrade and a failure error code.

[0039] This embodiment, in the efficient path of autonomous device upgrades, introduces a mobile terminal as a user authorization agent as a control node. This ensures that each upgrade is no longer a silent process but a controllable upgrade requiring user knowledge and permission, achieving an optimal balance between automation and user control. It constructs a unified device management experience and status visibility: regardless of the device's capabilities, the mobile terminal serves as a unified control panel and status dashboard for managing all devices. Users do not need to learn how to manage different devices or check status on multiple platforms; they can complete upgrade authorization and progress monitoring for all devices directly on the mobile terminal, achieving centralized and visualized management.

[0040] In an exemplary embodiment of this disclosure, a proxy upgrade process is performed as a communication proxy between a device and a cloud server, including performing the following steps S1-S6: Step S1: Extract the device's identification information from the device's information, use it as the device's registration agent, initiate a device registration request to the cloud server, bind the device to the corresponding family account, and establish a logical subscription relationship between the device and the remote upgrade service; wherein, the device registration request carries the device's identification information and the family account's identification information; Step S2: Receive a batch upgrade task notification pushed by the cloud server according to the logical subscription relationship, which contains an overview of at least one independent upgrade item; Step S3: Show the user the overview information in the batch upgrade task notification, and after obtaining unified authorization from the user, send authorization confirmation to the cloud server; Step S4: Receive upgrade instructions for each independent upgrade item sequentially from the cloud server in response to the authorization confirmation; Step S5: For the upgrade instruction of the currently received independent upgrade item, download the corresponding new version firmware file from the cloud server, and perform integrity verification and security verification using the verification credentials provided by the cloud; only after the verification is successful, transmit the verified firmware file to the device through a short-range wireless communication connection to trigger the device to burn the new version firmware file into the corresponding hardware module of the device and perform firmware upgrade; Step S6: Receive the upgrade result message from the device for the current independent upgrade item, and forward the upgrade result message to the cloud server; Step S1 is the initialization step executed when the device first connects to the network; steps S2 to S6 are upgrade execution steps that are repeatedly executed in response to various remote upgrade tasks issued by the cloud server during the device's life cycle.

[0041] This embodiment enables low-cost, low-power devices lacking WAN connectivity to achieve the same remote management and secure upgrade capabilities as high-end devices (with WAN connectivity) through a mobile terminal proxy, completely breaking the constraint of hardware cost on upgradeability. Through a collaborative mechanism of "batch tasks - sequential execution," centralized scheduling, sequential control, and atomic feedback are achieved for the upgrade process of multiple modules. This ensures that the upgrade process strictly adheres to the dependencies between modules, avoiding system risks caused by disordered upgrade order, and is particularly suitable for complex systems such as home energy storage devices.

[0042] like Figure 3 As shown, one embodiment of this disclosure provides a remote upgrade method applied to a cloud server, including: Step S10: Receive a user registration request from a mobile terminal and register a family account for the user; wherein, the user is a user of a home energy storage device; Step S20: Obtain the device's WAN connectivity information, and select whether the device has WAN connectivity to complete the device registration, family account binding, and remote upgrade service subscription directly or indirectly through the mobile terminal as a communication proxy between the device and the cloud server, depending on whether the device has WAN connectivity. Step S30: When it is detected that the device has firmware to be upgraded, a batch upgrade task is generated and an upgrade notification is sent to the mobile terminal corresponding to the device. After receiving the user authorization response from the mobile terminal in response to the upgrade notification, the corresponding upgrade method is selected according to the device's WAN connectivity: if the device has WAN connectivity, upgrade instructions are sent directly to the device in sequence according to the batch upgrade task and the upgrade result information fed back by the device is received; if the device does not have WAN connectivity, upgrade instructions are sent to the mobile terminal in sequence according to the batch upgrade task and the upgrade result information forwarded by the mobile terminal from the device is received.

[0043] In this embodiment of the remote upgrade method, the cloud server receives a user registration request from a mobile terminal and registers a family account for the user; wherein the user is a user of a home energy storage device; the server obtains the device's WAN connectivity information and, depending on whether the device has WAN connectivity, selects whether to directly complete the device registration, family account binding, and remote upgrade service subscription through the mobile terminal acting as a communication proxy between the device and the cloud server; when firmware to be upgraded is detected on the device, a batch upgrade task is generated and an upgrade notification is sent to the mobile terminal corresponding to the device; after receiving the user authorization response from the mobile terminal in response to the upgrade notification, the server selects the corresponding upgrade method based on the device's WAN connectivity: if the device has WAN connectivity, upgrade instructions are sent directly to the device according to the batch upgrade task, and the upgrade result information fed back by the device is received; if the device does not have WAN connectivity, upgrade instructions are sent to the mobile terminal according to the batch upgrade task, and the upgrade result information forwarded by the mobile terminal from the device is received. The above remote upgrade method uses centralized cloud control and designs a dual-channel upgrade mechanism to address the differences in network capabilities of home energy storage devices, achieving efficient, reliable, and universally applicable remote firmware upgrades.

[0044] In an exemplary embodiment of this disclosure, the WAN connectivity information of the device is obtained, and based on whether the home energy storage device has WAN connectivity, the device is selected to directly complete or indirectly complete the device registration, family account binding, and remote upgrade service subscription either through the mobile terminal acting as a communication proxy between the device and the cloud server. This includes: If a device registration request is received directly from the home energy storage device, it is determined that the home energy storage device has wide area network connectivity, and this information is recorded. The device registration request carries the device's identification information and the family account's identification information. After verifying the information carried in the device registration request, the device is officially registered and bound to the family account. Based on the MQTT (Message Queuing Telemetry Transport) protocol, a dedicated upgrade status feedback topic for the device is subscribed to. If a device registration request initiated by the mobile terminal is received, it is determined that the home energy storage device does not have wide area network connectivity, and this information is recorded; wherein, the device registration request carries the identification information of the device and the identification information of the family account; after verifying the information carried in the device registration request, the device is officially registered and bound to the family account; a logical subscription relationship between the device and the remote upgrade service is established.

[0045] The above method identifies the network communication capabilities of a device when it first connects to the cloud, and constructs a flexible, adaptive, and scalable device access and service framework, providing a systematic solution for the management of IoT devices in heterogeneous network environments.

[0046] In an exemplary embodiment of this disclosure, when the device has firmware to be upgraded, a batch upgrade task is generated and an upgrade notification is sent to the corresponding mobile terminal, including: When a new firmware version is detected, the aggregation strategy engine will automatically run to generate batch upgrade tasks; The aggregation strategy includes at least one of the following: Based on the dependencies between hardware modules, the firmware of multiple hardware modules that have strong dependencies or need to be upgraded synchronously is aggregated. Aggregate firmware for multiple hardware modules that are released in the same batch within the same time window.

[0047] In one exemplary embodiment of this disclosure, the upgrade notification includes an overview of each individual upgrade item in the batch upgrade task. This overview information is user-friendly text explaining the content of the firmware upgrade; it is part of the user experience design and aims to inform the user of the purpose and benefits of the upgrade, thereby encouraging the user to authorize the upgrade.

[0048] In an exemplary embodiment of this disclosure, the upgrade instruction includes at least one of the following information: firmware version number, download address of firmware file, integrity verification information (e.g., MD5 code), upgrade text, and risk warning information before upgrade.

[0049] In an exemplary embodiment of this disclosure, if the device has wide area network connectivity, upgrade instructions are sequentially sent to the device according to the batch upgrade task, and upgrade result information is received from the device, including: Through the dedicated MQTT remote upgrade service topic subscribed to by the device, upgrade instructions for each independent upgrade item are issued sequentially according to the order of batch upgrade tasks; After issuing the upgrade instruction for each individual upgrade item, obtain the upgrade result information published by the device in the upgrade status feedback topic.

[0050] In an exemplary embodiment of this disclosure, if the device has wide area network connectivity, after issuing upgrade instructions to the device sequentially according to the batch upgrade task and receiving upgrade result information from the device, the method further includes: The upgrade result information of the device is forwarded to the mobile terminal.

[0051] In an exemplary embodiment of this disclosure, the instructions for each independent upgrade item include at least one of the following information: firmware version number, download address of firmware file, integrity verification information (e.g., MD5 code), upgrade text, and risk warning information before upgrade.

[0053] In this embodiment, the home energy storage device's information acquisition module acquires device information and determines whether the device has wide area network (WAN) connectivity based on this information. If the upgrade module determines that the device has WAN connectivity, it executes an autonomous remote upgrade process; if it determines that the device does not have WAN connectivity, it completes the remote upgrade process using a mobile terminal.

[0057] Steps S1 and S2 are initialization steps performed when the device first accesses the network; steps S3 to S6 are upgrade execution steps that are repeatedly performed in response to various upgrade tasks issued by the cloud server during the device's lifecycle.

[0061] In an exemplary embodiment of this disclosure, the upgrade module is configured to complete the remote upgrade process via a mobile terminal by executing the following steps S1-S3: Step S1: Establish a short-range wireless communication connection with the mobile terminal and send device information to the mobile terminal; wherein, the mobile terminal acts as the registration agent of the device, initiates a device registration request to the cloud server and binds the device to the corresponding family account, establishing a logical subscription relationship between the device and the remote upgrade service; the device information includes the device's identification information and hardware configuration information; the device registration request carries the device's identification information and the family account's identification information; Step S2: Receive the verified firmware file sent by the mobile terminal via a short-range wireless communication connection, and burn it to the target hardware module to perform a firmware upgrade; wherein, after receiving the remote upgrade task notification pushed by the cloud server according to the logical subscription relationship, the mobile terminal parses the notification to obtain the description information and verification credentials of the target firmware file, downloads the corresponding new version firmware file from the cloud server according to the description information, performs integrity verification and security verification on the downloaded firmware file using the verification credentials, and only transmits the verified firmware file to the device via a short-range wireless communication connection after successful verification; Step S3: Send an upgrade result message to the mobile terminal, and the mobile terminal forwards the upgrade result message to the cloud server; Step S1 is the initialization step executed when the device first accesses the network; steps S2 to S3 are upgrade execution steps that are repeatedly executed in response to various upgrade tasks issued by the cloud server during the device's life cycle.

[0062] In an exemplary embodiment of this disclosure, the upgrade module is configured to complete the remote upgrade process using a mobile terminal in the following manner: when the upgrade task message contains multiple independent upgrade items, the mobile terminal sequentially performs the following processing for each independent upgrade item: parsing the upgrade item, downloading the corresponding firmware file, verifying the downloaded file, and transmitting the verified file to the device; the device sequentially performs upgrade operations according to the received firmware file; after completing the upgrade operation for any independent upgrade item, the device sends an upgrade result message for that item to the mobile terminal, and the mobile terminal forwards the upgrade result message to the cloud server.

[0063] In an exemplary embodiment of this disclosure, the instructions for each independent upgrade item include at least one of the following information: firmware version number, download address of firmware file, integrity verification information (e.g., MD5 code), upgrade text, and risk warning information before upgrade.

[0064] like Figure 5 As shown, one embodiment of this disclosure provides a mobile terminal, including: a user registration module 100, an information acquisition module 200, and an upgrade module 300; The user registration module is configured to send a user registration request to the cloud server and obtain the family account assigned by the cloud server to the user of the home energy storage device. The information acquisition module is configured to establish a short-range wireless communication connection with the home energy storage device, acquire information about the device, and determine whether the device has wide area network connectivity based on the information. The upgrade module is configured to send home network configuration information and home account identification information to the device if it determines that the device has WAN connectivity, so that the device can perform an autonomous remote upgrade process; if it determines that the device does not have WAN connectivity, it acts as a communication proxy between the device and the cloud server and performs a proxy upgrade process.

[0065] In this embodiment, the mobile terminal establishes a short-range wireless communication connection with the home energy storage device, acquires the device's information, and determines whether the device has wide area network (WAN) connectivity based on this information. If the upgrade module determines that the device has WAN connectivity, it sends home network configuration information and home account identification information to the device, enabling the device to autonomously complete registration and binding in the cloud. If the module determines that the device does not have WAN connectivity, it acts as a communication proxy between the device and the cloud server, executing a proxy upgrade process. This remote upgrade method adaptively adapts to the two remote upgrade modes of home energy storage devices on the mobile terminal side. On the one hand, it enables high-end home energy storage devices with built-in WAN connectivity to conveniently and autonomously complete the entire upgrade process; on the other hand, it enables low-complexity, low-cost home energy storage devices without WAN connectivity to obtain the same remotely manageable upgrade capabilities as high-end devices through the proxy capability of the mobile terminal. This fundamentally breaks the limitation of device hardware cost on upgradeability, greatly expands the physical form and cost boundaries of home energy storage devices that can support remote upgrades, and provides a convenient and reliable solution for the large-scale deployment and operation and maintenance of IoT devices.

[0066] In one exemplary embodiment of this disclosure, the mobile terminal includes: mobile phone, tablet computer, laptop computer, e-reader, wearable smart device, etc.

[0067] In an exemplary embodiment of this disclosure, the information acquisition module is configured to determine whether the device has wide area network (WAN) connectivity capability based on the device's information in the following manner: parsing the hardware configuration information in the device's information; when the hardware configuration information indicates that the device integrates at least one of a wireless local area network (WLAN) access module or a cellular mobile communication module, determining that the device has WAN connectivity capability; otherwise, determining that the device does not have WAN connectivity capability.

[0068] In an exemplary embodiment of this disclosure, the agent upgrade process includes: registration and binding, establishing a subscription relationship, obtaining upgrade files and transmitting them to the device, and receiving upgrade result information from the device and transmitting it to the cloud server.

[0069] In an exemplary embodiment of this disclosure, the upgrade module is configured to send home network configuration information and home account identification information to the device by performing the following steps S1-S4, so that the device can perform an autonomous remote upgrade process: Step S1: Send home network configuration information and home account identification information to the device so that the device can use the information to complete cloud registration, account binding and MQTT service subscription; Step S2: Receive a batch upgrade task notification pushed by the cloud server based on the MQTT service subscribed to by the device, which contains an overview of at least one independent upgrade item; Step S3: Show the user the overview information in the batch upgrade task notification, and after obtaining unified authorization from the user, send an authorization confirmation to the cloud server so that the cloud server can send upgrade instructions for each independent upgrade item to the device in sequence. Step S4: Receive the final upgrade results of all firmware in the current batch of the device from the cloud server and present them to the user; Step S1 is the initialization step executed when the device first connects to the network; steps S2 to S4 are upgrade execution steps that are repeatedly executed in response to various remote upgrade tasks issued by the cloud server during the device's life cycle.

[0070] The overview information is user-friendly text explaining the content of this firmware upgrade. It is part of the user experience design and aims to inform users of the purpose and benefits of the upgrade in order to encourage users to authorize the upgrade.

[0071] In one exemplary embodiment of this disclosure, the upgrade result information includes: an indication of successful upgrade and the updated firmware version number, or an indication of failed upgrade and a failure error code.

[0072] This embodiment, in the efficient path of autonomous device upgrades, introduces a mobile terminal as a user authorization agent as a control node. This ensures that each upgrade is no longer a silent process but a controllable upgrade requiring user knowledge and permission, achieving an optimal balance between automation and user control. It constructs a unified device management experience and status visibility: regardless of the device's capabilities, the mobile terminal serves as a unified control panel and status dashboard for managing all devices. Users do not need to learn how to manage different devices or check status on multiple platforms; they can complete upgrade authorization and progress monitoring for all devices directly on the mobile terminal, achieving centralized and visualized management.

[0073] In an exemplary embodiment of this disclosure, the upgrade module is configured to act as a communication proxy between the device and the cloud server by performing the following steps S1-S6, thereby executing a proxy upgrade process: Step S1: Extract the device's identification information from the device's information, use it as the device's registration agent, initiate a device registration request to the cloud server, bind the device to the corresponding family account, and establish a logical subscription relationship between the device and the remote upgrade service; wherein, the device registration request carries the device's identification information and the family account's identification information; Step S2: Receive a batch upgrade task notification pushed by the cloud server according to the logical subscription relationship, which contains an overview of at least one independent upgrade item; Step S3: Show the user the overview information in the batch upgrade task notification, and after obtaining unified authorization from the user, send authorization confirmation to the cloud server; Step S4: Receive upgrade instructions for each independent upgrade item sequentially from the cloud server in response to the authorization confirmation; Step S5: For the upgrade instruction of the currently received independent upgrade item, download the corresponding new version firmware file from the cloud server, and perform integrity verification and security verification using the verification credentials provided by the cloud; only after the verification is successful, transmit the verified firmware file to the device through a short-range wireless communication connection to trigger the device to burn the new version firmware file into the corresponding hardware module of the device and perform firmware upgrade; Step S6: Receive the upgrade result message from the device for the current independent upgrade item, and forward the upgrade result message to the cloud server; Step S1 is the initialization step executed when the device first connects to the network; steps S2 to S6 are upgrade execution steps that are repeatedly executed in response to various remote upgrade tasks issued by the cloud server during the device's life cycle.

[0074] This embodiment enables low-cost, low-power devices lacking WAN connectivity to achieve the same remote management and secure upgrade capabilities as high-end devices (with WAN connectivity) through a mobile terminal proxy, completely breaking the constraint of hardware cost on upgradeability. Through a collaborative mechanism of "batch tasks - sequential execution," centralized scheduling, sequential control, and atomic feedback are achieved for the upgrade process of multiple modules. This ensures that the upgrade process strictly adheres to the dependencies between modules, avoiding system risks caused by disordered upgrade order, and is particularly suitable for complex systems such as home energy storage devices.

The aforementioned remote upgrade method is centrally controlled via the cloud and features a dual-channel upgrade mechanism designed to address the differences in network capabilities of home energy storage devices, enabling efficient, reliable, and universally applicable remote firmware upgrades.

[0077] In an exemplary embodiment of this disclosure, the second registration module is configured to, upon receiving a device registration request directly initiated by the home energy storage device, determine that the home energy storage device has wide area network (WAN) connectivity and record this information; wherein the device registration request carries the device's identification information and the family account's identification information; after verifying the information carried in the device registration request, formally register the device and bind it to the family account; subscribe to the device's dedicated upgrade status feedback topic based on the MQTT (Message Queuing Telemetry Transport) protocol; if a device registration request is received from the mobile terminal, determine that the home energy storage device does not have WAN connectivity and record this information; wherein the device registration request carries the device's identification information and the family account's identification information; after verifying the information carried in the device registration request, formally register the device and bind it to the family account; and establish a logical subscription relationship between the device and the remote upgrade service.

[0078] This embodiment identifies the device's network communication capabilities when the device first connects to the cloud, and constructs a flexible, adaptive, and scalable device access and service framework, providing a systematic solution for IoT device management in heterogeneous network environments.
