Brovolthas launched an advanced energy storage system solution designed to provide stable, efficient, and secure energy management for photovoltaic, wind power, and other renewable energy projects. The system adopts a DC1000V energy storage solution with a specification of 200KW/1.1712MWh, integrating a lithium iron phosphate (LiFePO4) battery system, Battery Management System (BMS), Power Conversion System (PCS), Energy Management System (EMS), as well as fire protection and temperature control systems, meeting the high demands for safety, reliability, and efficiency in modern renewable energy applications.
Key Technical Highlights:
1.Battery System
The energy storage system features a nominal voltage of 768V with lithium iron phosphate battery packs configured at 3.2V280Ah, organized in a 5P240S structure, and utilizing a forced air-cooling system. The design is simple, reliable, and easy to maintain, ensuring long-term stable operation.
2. Battery Management System (BMS)
The system is equipped with a two-level BMS. The primary BMS monitors the real-time voltage and temperature of each individual cell and provides balancing functions. The secondary BMS manages the battery clusters, implements balancing strategies, fault diagnosis, and battery protection functions, ensuring safe operation of the entire energy storage system under various conditions.
3.Power Conversion System (PCS)
The system is equipped with two 105kW PCS units, providing a maximum output power of 210kW, capable of meeting the nominal power requirement of 200kW. It ensures efficient charging and discharging while seamlessly integrating with the grid, making it suitable for different renewable energy integration scenarios.
4.Energy Management System (EMS)
This energy storage solution is equipped with an integrated touch-screen EMS system that combines HMI and controller functions. The system directly interfaces with the cloud platform for remote monitoring and data analysis, supporting visual management of devices, improving operational convenience and efficiency.
5.Safety and Fire Protection Design
To ensure system safety, each energy storage cabinet is equipped with an aerosol fire extinguishing system and detection devices. In the event of thermal runaway in the battery cells or component short circuits causing a fire, the system automatically activates the fire suppression system. Additionally, a sound and light alarm is installed outside the cabinet to alert personnel for timely action.
Operating Strategy:
This energy storage system is designed for one charge-discharge cycle per day, with a depth of discharge (DOD) ranging from 10% to 90%, and a maximum charging and discharging power of 200kW. The system will perform no more than one charge-discharge cycle per day, meeting the needs for frequency regulation and load adjustment in renewable energy projects.
Conclusion:
Brovolt’s new energy storage system is not only highly efficient in energy management but also optimized for safety, flexibility, and maintainability. It provides stable grid frequency regulation and peak-shaving functions for renewable energy projects such as photovoltaic and wind power, improving energy utilization efficiency and promoting sustainable development of green energy.
