These data configuration types are complex, the data volume is large, and the access network methods are diverse, including Ethernet, serial ports, IO and other heterogeneous network methods. In the existing technology, access is mainly carried out by manually configuring point tables, which is complex, inefficient, and prone to errors.

[0049] Based on the above problems, an embodiment of the present application proposes a device access method, which is applied to an energy storage system.

[0050] Now combined Figure 1-3 The device access method provided in the embodiment of the present application is described.

[0051] like Figure 1The figure is a flow chart of an embodiment of the device access method provided by the present application, which specifically includes the following steps:

[0052] Step 110: receiving access information of an energy storage device, where the access information is used to represent the request information of the energy storage reserve to be connected for applying to access the energy storage system.

[0053] Specifically, the embodiment of the present application proposes a device access method for an energy storage system, which is applied to an energy storage system, wherein the energy storage system includes an energy storage device, and the energy storage system is connected to a cloud platform for communication. First, the energy storage system receives access information of the energy storage device, and the access information is used to characterize the request information of the energy storage reserve to be connected to apply for access to the energy storage system. The energy storage system proposed in the present application may include an electrochemical energy storage system, which is a technology that converts electrical energy and stores it into chemical energy, and stores and releases energy through the mechanism of chemical batteries. Energy storage devices are systems or devices used to store energy, which can store energy when energy is generated and release energy for use when needed. This application does not specifically limit this. When the energy storage device needs to access the energy storage system, it will send a request access information to the energy storage system. After the energy storage system receives the access information of the energy storage device, it will notify the cloud platform that there is an energy storage device connected at this time. After the cloud platform receives the information, it will perform initialization operations and create a main device model, a sub-device model, and an auxiliary device model to access the energy storage device.

[0054] Step 120 , scan the QR code of the energy storage device to be connected, and identify the device ID, device type, access method, and communication protocol of the energy storage device to be connected.

[0055] Specifically, the embodiments of the present application propose that after receiving the access information of the energy storage device, the energy storage system will further scan the QR code of the energy storage device to be connected to identify the device ID, device type, access method and communication protocol of the energy storage device to be connected. Among them, the QR code of the energy storage device to be connected contains the device ID, device type, access method and communication protocol information of the energy storage device; the device ID is the unique identifier of the energy storage device, which is crucial for the tracking, management, maintenance and integration of the device; the access method is to automatically access the energy storage system or to access the energy storage system by scanning the QR code; the communication protocol may include the Modbus communication protocol, the CAN communication protocol and the MQTT communication protocol, among which Modbus is an application layer protocol that can be used for communication between the energy storage inverter and the battery management system, the CAN communication protocol is a controller area network, which is a bus-based data communication protocol, and the MQTT communication protocol is a lightweight message transmission protocol.

[0056] Step 130: Receive model information from the cloud platform, the model information includes model creation information and model identification information, and parse the model information.

[0057] Specifically, the embodiments of the present application propose that after identifying the device ID, device type, access method and communication protocol of the energy storage device to be connected, model registration information is sent to the cloud platform based on the device ID, device type, access method and communication protocol. The model registration information is used to characterize that the cloud platform registers the corresponding model based on the device ID, device type, access method and communication protocol. The cloud platform will first create a main device model, a sub-device model and an auxiliary device model; then, after receiving the model registration information of the device ID, device type, access method and communication protocol of the energy storage device sent by the energy storage system, the cloud platform parses and identifies the corresponding device ID model, device type model, access method model and communication protocol model based on the corresponding device ID, device type, access method and communication protocol. Model information is sent to the energy storage device, and the model information includes model creation information and model identification information; the model creation information is used to characterize that the cloud platform creates a main device model, a sub-device model, and an auxiliary device model in response to an access request of the energy storage device to be connected; the model identification information is used to characterize that after the cloud platform creates the model, it parses and identifies the device ID model, device type model, access mode model, and communication protocol model of the energy storage device to be connected, and sends the device ID model, device type model, access mode model, and communication protocol model to the energy storage system in the format of MQTT or json. The energy storage system and the cloud platform establish a communication connection with the energy storage device to be connected based on the access mode model and the communication protocol model. The type of communication protocol is not specifically limited in this application. The cloud platform will also periodically create and modify model information, and generate an iterative version of the model. When the model is created or modified, it will be sent to the energy storage system to achieve synchronous update of the model between the cloud platform and the energy storage system.

[0058] Furthermore, the model identification information also includes QR code model identification information and proxy model identification information; the QR code model identification information is used to represent that the cloud platform identifies the device ID model, device type model, access method model and communication protocol model of the energy storage device to be connected by scanning the QR code; the proxy model identification information is used to represent that the cloud platform identifies the device ID model, device type model, access method model and communication protocol model of the energy storage device to be connected by means of the main device model bus agent.

[0059] The energy storage system receives the model information and configuration information sent by the cloud platform. The model information includes model creation information and model identification information. The model creation information is the cloud platform creating the main device model, sub-device model and auxiliary device model based on the object model. The model identification information is the cloud platform creating the device ID model, device type model, access mode model and communication protocol model of the energy storage device to be connected based on the object model. Further, the energy storage system parses the model information sent by the cloud platform and obtains the device ID model, device type model, access mode model and communication protocol model created by the cloud platform. Among them, the main device model (System Control Unit, SCU) includes the device ID model, software and hardware version model, communication access mode model, protocol type model, network type model, network status model, CPU load model, memory usage model, disk usage model, and system topology model; the sub-device model (Backup Control Unit, BCU) includes the device address model, protocol type model, network type model, network status model, battery stack model, battery cluster model, single cell model, liquid cooler model, temperature and humidity sensor model, water immersion model, and IO device model corresponding to the main device model; the battery stack model includes the number of battery clusters per stack model, the number of battery single cells per cluster model, timestamp model, system fault status, system operation status, stack voltage, stack current, stack SOC, stack SOH, stack SOE and other telemetry information; remote control information such as stack DC circuit breaker control and fault recovery; remote signal information of cluster communication faults and faults in each group of stacks, and remote adjustment information of each alarm fault threshold in the battery cluster model. Through various stack-level fault judgment algorithms and SOC, SOH, SOP, SOE and other algorithms, the above models are saved to the cloud platform and sent to the energy storage device.

[0060] Exemplarily, taking the sub-device model as a battery stack model, after the cloud platform creates the device ID model, device type model, access mode model and communication protocol model of the main device model corresponding to the battery stack model, the battery stack model and its auxiliary device model are further created according to the topological relationship between the main device model and the sub-device model. Specifically, the cloud platform creates a stack number model, a system fault status model, a system operation status model, a stack voltage model, a stack current model, a stack SOC model, a stack SOE model, and a cluster communication fault model. Furthermore, the cloud platform creates an alarm auxiliary device model in the battery stack model, such as: each group in the stack The cloud platform creates fault recovery models in the battery stack model, such as: stack DC circuit breaker control model, cluster voltage difference too large level 1 fault threshold model, cluster voltage difference too large level 2 fault threshold model, cluster voltage difference too large level 3 fault threshold model, cluster voltage difference too large level 1 recovery threshold model, cluster voltage difference too large level 2 recovery threshold model, cluster voltage difference too large level 3 recovery threshold model. After the cloud platform creates the main device model, sub-device model and auxiliary device model, it sends the model information to the energy storage system and waits for the energy storage system to analyze it.

[0061] The device ID model, device type model, access mode model and communication protocol model correspond one-to-one to the device ID, device type, access mode and communication protocol of the energy storage device to be connected. The configuration information is used to characterize the device ID model, device type model, access mode model and communication protocol model corresponding to the device to be connected configured by the cloud platform. When the energy storage system receives the access request information of the energy storage device to be connected, the historical main device model in the energy storage system will automatically identify the number of sub-device models, automatically create a topology model of the main device model and the sub-device model, automatically build the corresponding topology tree, record the topology data, and report the topology data to the cloud platform in json format.

[0062] Step 140: access the energy storage device to be accessed based on the device ID model, device type model, access mode model and communication protocol model of the energy storage device to be accessed.

[0063] Specifically, the embodiments of the present application propose that after obtaining the device ID model, device type model, access mode model and communication protocol model created and issued by the cloud platform, the energy storage device to be connected is accessed based on the device ID model, device type model, access mode model and communication protocol model of the energy storage device to be connected. The device ID model, device type model, access mode model and communication protocol model are generated and configured by the cloud platform, and are sent to the energy storage system in mqtt or json format. The energy storage system parses the device ID model, device type model, access mode model and communication protocol model files to complete the automatic access of the energy storage device to the energy storage system and the cloud platform. After accessing the energy storage device to be connected, the energy storage system will continue to collect data information of the energy storage device and report the data information to the cloud platform in real time.

[0064] Exemplary, combined Figure 2 The device access method provided in the embodiment of the present application is further described. One embodiment of the present application proposes that the energy storage device to be connected accesses the energy storage system and the cloud platform by scanning a QR code. Specifically, when the energy storage device to be connected applies for access, the cloud platform creates or modifies a model library, which includes a main device model, a sub-device model, and an accessory device model. The energy storage device scans the main device model QR code and applies for access to the energy storage system. The energy storage system first parses the QR code information, wherein the QR code information includes the device type, access method, communication protocol, and device ID. The energy storage device registers the main device model to the cloud platform, and the energy storage system uploads the main device model to the cloud platform; detects whether all main device model scans are completed, and if not, continues to parse the QR code. If all scans have been completed, the energy storage device scans the sub-device model QR code, and the energy storage system parses the QR code information, wherein the QR code information includes the device type, access method, communication protocol, and device ID. The energy storage device registers the sub-device model to the cloud platform; detects whether all sub-device model scans are completed, and if not, continues to parse the QR code. If all scans have been completed, the energy storage device scans the QR code of the accessory device, and the energy storage system parses the QR code information, where the QR code information includes the device type, access method, communication protocol and device ID. The energy storage device registers the accessory model to the cloud platform; it checks whether all accessory device model scans have been completed, and if not, continues to parse the QR code. If all scans have been completed, the cloud platform generates the main device model and the sub-device model topology and data model, and the cloud platform sends the model to the energy storage system. The energy storage system parses the model to create a sub-device access thread to complete data collection. Finally, the energy storage device completes the reporting of the main device data and sub-device data to the cloud platform.

[0065] Exemplary, combined Figure 3The device access method provided in the embodiment of the present application is further described. One embodiment of the present application proposes that the energy storage device to be connected accesses the energy storage system and the cloud platform through a proxy method. Specifically, when the energy storage device to be connected applies for access, the cloud platform creates or modifies a model library, which includes a main device model, a sub-device model, and an accessory device model. The energy storage device scans the main device model QR code and applies for access to the energy storage system. The energy storage system first parses the QR code information, wherein the QR code information includes the device type, access method, communication protocol, and device ID. The energy storage device registers the main device model to the cloud platform, and the energy storage system uploads the main device model to the cloud platform. The sub-device model manually assigns an address through networking, the main device model starts scanning the sub-device model, reads the device type, access method, communication protocol, and device ID through network broadcasting, and the main device model acts as a proxy for the sub-device model to the cloud platform; the accessory device model manually assigns an address through networking, the main device model starts scanning the accessory device model, reads and identifies the device type, access method, communication protocol, and device ID through the bus, and the main device model acts as a proxy for the accessory device model to the cloud platform. The cloud platform generates the main device model and sub-device model topology and data model. The cloud platform sends the model to the energy storage system. The energy storage system analyzes the model to create a sub-device access thread to complete data collection. Finally, the energy storage device completes the reporting of the main device data and sub-device data to the cloud platform.

[0066] The device access method provided in the embodiment of the present application helps to solve the problem that the device is accessed by manually configuring a point table, which is complex, inefficient, and error-prone. It can achieve rapid access and monitoring of energy storage devices based on the physical model by using QR code scanning and master device model proxy through the collaboration of the cloud platform and the energy storage system.
