[0064] refer to Figure 1 and Figure 2 Specifically, the configuration device for monitoring the energy storage container includes an energy storage container monitoring and control system based on a configuration screen:

[0065] The monitoring and control system consists of two parts: hardware and software. The hardware includes a configuration screen, a communication interface and wiring harness, relays, sensors, and EMU. The configuration screen is connected to the EMU through the communication interface and wiring harness of the configuration screen, so that the energy storage device can be monitored and controlled through the configuration screen. The software part includes software for reading and displaying the device status, writing and controlling the device. The software can read and display the temperature and voltage of the battery cell, the battery cluster status, the relay status, the PCS status, and the alarm information in real time. It can issue instructions to start and stop the PCS, and can issue power control instructions for the PCS.

[0066] Specifically, the hardware system includes a configuration screen, a communication interface and wiring harness, relays, sensors, and EMU, and its beneficial effects include:

[0067] 1. Real-time monitoring and control:

[0068] Through the communication connection between the configuration screen and the EMU, the status of the energy storage equipment can be monitored in real time, including key parameters such as power, temperature, and pressure.

[0069] The interface on the configuration screen allows the operator to directly remotely control the energy storage equipment, such as starting, stopping, adjusting the working mode, etc.

[0072] The precise operation of relays and sensors helps to detect and handle equipment failures in a timely manner and prevent potential safety hazards.

[0073] 3. Optimize energy efficiency management:

[0074] The system can automatically adjust its working mode according to the real-time status of the energy storage equipment to optimize energy utilization efficiency.

[0075] Through data analysis, the system can also predict the energy consumption trend of energy storage equipment and provide data support for future energy efficiency improvements.

[0076] It should be noted that the system can automatically adjust its working mode according to the real-time status of the energy storage device and predict the energy consumption trend of the energy storage device based on data analysis, which provides important support for optimizing energy utilization efficiency. In the process of realizing this function, the optimization algorithm based on the large model plays a key role, including:

[0077] a. Real-time status monitoring and mode adjustment algorithm module, which is used to build a real-time status model of energy storage equipment by integrating sensor data, historical operation records and real-time environmental parameters (such as temperature, humidity, etc.).

[0078] Based on this model, the system can evaluate the operating status of the equipment in real time and automatically adjust the working mode according to the preset optimization goals (including maximizing energy efficiency and minimizing energy loss). For example, during peak power demand periods, the system will adjust the energy storage equipment to provide additional power support; and during low demand periods, it will be adjusted to charging or maintenance mode.

[0079] b. Energy consumption trend prediction algorithm module, which uses big data analysis technology to conduct in-depth mining and machine learning of historical energy consumption data to identify the laws and trends of energy consumption changes. By building an energy consumption prediction model, the system can predict energy consumption in the future and provide data support for energy efficiency improvement. These prediction data help to formulate more accurate energy management strategies, such as adjusting the charging and discharging plans of energy storage equipment and optimizing energy distribution.

[0080] c. Intelligent optimization and decision support algorithm module, based on real-time status monitoring and energy consumption trend prediction, intelligent optimization and decision support algorithms can comprehensively consider multiple factors (such as energy prices, market demand, equipment operating costs, etc.) to provide the best energy management solution for the system. These algorithms include advanced optimization algorithms (including genetic algorithms and particle swarm algorithms) and machine learning models (including neural networks and support vector machines) to achieve intelligent solutions to complex energy management problems.

[0081] In this embodiment, the key elements of algorithm implementation include: data quality: ensuring the accuracy and completeness of sensor data, as well as the reliability and consistency of historical data; model training and optimization: model training and parameter optimization based on high-quality data to improve the accuracy of prediction and optimization; system integration and compatibility: ensuring seamless integration of the algorithm with existing systems, as well as compatibility with other hardware and software components; real-time and response speed: the algorithm needs to have the ability to respond quickly and process in real time to meet the system's needs for real-time status monitoring and adjustment.

[0082] 4. Simplify operation and maintenance:

[0083] The configuration screen provides an intuitive user interface, allowing operators to easily understand the equipment status and perform necessary operations.

[0084] The system supports remote fault diagnosis and upgrades, reducing the need and cost of on-site maintenance.

[0085] 5. Enhance system scalability:

[0086] Through modular design, the system can easily add new monitoring and control functions to adapt to the development of future energy storage technology.

[0087] The standardized design of communication interface and wiring harness makes integration with other systems easier.

[0088] 6. Improved security:

[0089] The real-time monitoring function helps to detect equipment abnormalities in a timely manner and prevent safety accidents caused by failures.

[0090] The system supports safety alarm and emergency shutdown functions, which can protect the safety of equipment and personnel in emergency situations.

[0091] In summary, by integrating multiple hardware components, comprehensive monitoring and control of energy storage equipment is achieved, thereby improving the system's reliability, energy efficiency, ease of operation, scalability, and safety.

[0092] Furthermore, the configuration screen realizes data input and output through its attached GPIO port. The input IO port is connected to the data output port of the EMU, thereby indirectly realizing the monitoring of battery temperature, battery pressure, battery working status, PCS power, and PCS working status.

[0093] The configuration screen can also freely set the active power and reactive power of PCS through the set program. At the same time, the active power and reactive power of PCS can be displayed on the configuration screen. The set power transmission control instructions are sent to EMU through the IO port, and PCS is controlled by EMU, thereby indirectly realizing the power control of PCS.

[0094] The output IO port of the configuration panel is connected to the EMU, and the EMU is connected to the relay of the PCS. The configuration panel indirectly drives the relay to control the start and stop actions of the PCS according to the set program to realize the pre-charge and pre-discharge operations of the battery.
