2、 Core functions

（1） Real time monitoring

• Equipment status monitoring: capable of real-time collection of operational data such as voltage, current, temperature, power, etc. of key equipment in the energy storage system, including battery packs, energy storage converters (PCS), battery management systems (BMS), and distribution cabinets. It's like installing a 'health monitor' on every device to keep track of their operating status at all times. For example, by monitoring the temperature of the battery pack, abnormal temperature increases can be detected in a timely manner to avoid battery damage caused by overheating.

• Environmental parameter monitoring: Monitor the environmental parameters of energy storage power plants, including environmental temperature, humidity, etc. Environmental factors can have an impact on the performance and lifespan of energy storage devices, and the platform provides suitable environmental references for device operation by monitoring these parameters. For example, in high temperature and high humidity environments, take measures in advance to prevent equipment from getting damp or malfunctioning due to poor heat dissipation.

（2） Data Analysis and Statistics

• Operation data analysis: Conduct in-depth analysis of the collected equipment operation data, generate various reports and charts, such as daily reports, monthly reports, annual reports, etc. By analyzing the data, we can understand the operating trends, performance changes, and other aspects of the energy storage system. For example, analyzing the changes in the charging and discharging efficiency of a battery pack over time to determine the health status of the battery.

• Energy consumption statistics: Collecting data on the charging and discharging capacity, energy consumption, and other aspects of energy storage systems to help users understand the energy utilization situation of the energy storage system. This is crucial for evaluating the economic and energy-saving benefits of energy storage systems. For example, by calculating the amount of electricity charged and discharged by the energy storage system during peak and off peak periods, the cost of electricity saved by the energy storage system for users can be calculated.

（3） Control and regulation

• Charging and discharging control: Automatically control the charging and discharging process of the energy storage system based on factors such as grid load, electricity price policies, and energy storage system status. During periods of low electricity prices, control the charging of energy storage systems; During peak electricity price periods, control the discharge of energy storage systems to achieve peak valley arbitrage. For example, when the grid load is low and electricity prices are low, the platform automatically activates the charging function of the energy storage system to store electrical energy; When the power grid load is high and the electricity price is high, the platform automatically releases the stored electricity to supply the load for use.

• Power regulation: Real time adjustment of the output power of the energy storage system based on the demand of the power grid and the capacity of the energy storage system. When the frequency of the power grid fluctuates, the energy storage system can quickly adjust the output power, participate in the frequency regulation of the power grid, and maintain the stable operation of the power grid. For example, when the frequency of the power grid decreases, the energy storage system rapidly increases its output power to provide support for the grid.

（4） Fault warning and diagnosis

• Fault warning: By setting reasonable thresholds and algorithms, real-time monitoring and analysis of equipment operating data are carried out. When the operating parameters of the equipment exceed the normal range, timely warning information is issued. For example, when the voltage of the battery pack is too high or too low, the platform will immediately issue a warning to remind the operation and maintenance personnel to handle it in a timely manner to avoid the fault from expanding.

• Fault diagnosis: When equipment malfunctions, the platform can diagnose and analyze the fault, determine the type, location, and cause of the fault, and provide corresponding solutions. This greatly shortens the time for troubleshooting and repair, and improves the availability of the energy storage system. For example, when the energy storage inverter malfunctions, the platform can quickly locate the fault point and guide maintenance personnel to carry out repairs by analyzing the fault code and operating data.

（5） Remote management

• Remote monitoring: users can access the energy storage monitoring platform remotely at any time and anywhere through the Internet to view the operation status and data of the energy storage system in real time. Even if not on site at the energy storage plant, one can still have a comprehensive understanding of the system. For example, enterprise managers can log in to the platform through a computer or mobile phone in the office to check the operation status of their subordinate energy storage power plants.

• Remote operation: supports remote operation of energy storage systems, such as remote start, stop of energy storage system charging and discharging, adjustment of equipment operating parameters, etc. This improves the efficiency and flexibility of operations and reduces the workload of on-site operations. For example, operation and maintenance personnel can remotely switch the operating mode of energy storage inverters.

3、 Platform advantages

Integrating various monitoring, control, and management functions in the energy storage system onto one platform avoids data silos and operational complexity between multiple systems. Users can complete comprehensive management of energy storage systems without switching between different software and systems. For example, on one platform, it is possible to simultaneously view the operational data of the battery pack, PCS, and BMS, and perform corresponding control operations.

（2） High degree of intelligence

Adopting advanced artificial intelligence and big data analysis technologies to achieve intelligent monitoring, control, and optimization of energy storage systems. The platform can automatically adjust control strategies based on historical data and real-time operating conditions, improving the operational efficiency and economic benefits of energy storage systems.

（3） Safe and reliable

Having a comprehensive security protection mechanism to ensure the data security of the platform and the stable operation of the system. Adopting technologies such as data encryption and user permission management to prevent data leakage and illegal access. At the same time, the platform has a highly reliable hardware and software architecture that can operate stably in various harsh environments. For example, by adopting redundant design and fault-tolerant mechanisms, the platform can still function normally when some devices fail.

（4） Strong scalability

The platform adopts modular design and has good scalability. Monitoring equipment and management functions can be flexibly added or reduced according to the scale and requirements of the energy storage system. Whether it is a small-scale household energy storage system or a large-scale industrial and commercial energy storage power station, the platform can be adapted. For example, when expanding an energy storage power station, simply adding the corresponding equipment monitoring module on the platform can achieve monitoring and management of the newly added equipment.

4、 Application scenarios

（1） Industrial and commercial energy storage power station

In industrial and commercial enterprises, energy storage monitoring platforms can help companies achieve peak valley electricity price arbitrage and reduce electricity costs. At the same time, during power outages, energy storage systems can serve as backup power sources to ensure the continuity of production for enterprises. For example, a large factory has installed an energy storage system that charges during low electricity prices and discharges during high electricity prices through a monitoring platform, saving a significant amount of electricity costs annually.

（2） Integrated photovoltaic storage and charging power station

The integrated photovoltaic storage and charging power station integrates functions such as photovoltaic power generation, energy storage, and charging piles. The energy storage monitoring platform can uniformly monitor and manage photovoltaic power generation, energy storage systems, and charging piles, achieving efficient utilization and optimized configuration of energy. For example, when there is sufficient photovoltaic power generation during the day, excess electricity can be stored; At night or when there is insufficient photovoltaic power generation, use energy storage systems to supply power to charging stations to meet the charging needs of electric vehicles.

（3） Microgrid energy storage system

A microgrid is a small power generation and distribution system composed of distributed power sources, energy storage devices, loads, and other components. The energy storage monitoring platform can monitor and control the energy storage system in the microgrid in real time, achieving stable operation of the microgrid and friendly interaction with the large grid. For example, when the distributed power generation in the microgrid is insufficient, the energy storage system can release electrical energy to ensure the normal power supply of the load in the microgrid; When there is an excess of distributed power generation in a microgrid, the energy storage system can store the excess electricity.

The Ankerui energy storage monitoring platform provides strong guarantees for the safe, stable, and efficient operation of energy storage systems with its comprehensive functions, significant advantages, and wide range of application scenarios. It is an important tool in the field of energy storage.
