LFP lithium iron battery system for megawatt power storage
Delta has launched an outdoor lithium-iron battery system specifically designed for megawatt (MW) level energy storage applications with sensors and control electronics.
The modular lithium iron phosphate (LFP) battery system addresses the urgent needs for grid ancillary services, solar plus storage, and backup power assurance. It can be configured with battery capacity according to actual project requirements, overcoming the challenges of fixed land space and inflexible configurations faced by 40-foot container-based systems, regardless of their capacity.
The lithium-iron battery system is pre-assembled with battery modules, power, and control equipment. It complies with IEEE 693 seismic certification and IEC 60721-3-2 transportation standards, facilitating transportation by truck and eliminating the need for multiple shipments and on-site battery assembly, thereby reducing the risk of project delays due to weather conditions at outdoor construction sites.
“As energy storage systems become increasingly familiar in the market, efficiency and safety are growing concerns for owners. The newly launched LFP lithium-iron battery system features compartmentalized design, fire-resistant casing, variable frequency energy-saving air conditioning, cooling systems, and sensors,” said Paul Ai, Delta’s Senior Director of Energy System Solutions Business Department.
“It incorporates multi-layer safety protection and management, aligns with international safety regulations, and meets battery protection requirements, effectively reducing the risk of accidents. Thanks to our resource and capability in manufacturing, battery laboratories, energy storage integration testing platforms, and a 24-hour operations and maintenance command centre, Delta understands the challenges and risks involved in MW-scale energy storage system deployment. This battery system not only addresses on-site installation issues but also enhances the overall system’s safety, ensuring smooth operation from design and construction to maintenance.”
The system allows for cabinet configuration according to the desired capacity, effectively utilizing land space. A single cabinet has a capacity of 315 kWh, and it can be expanded to a total of 5.67 MWh. This resolves the inflexibility issue faced by 40-foot container-based systems, where fixed land space is required regardless of the capacity.
he battery system is pre-assembled within the cabinets, including battery modules, auxiliary power, controllers, and communication interfaces. It undergoes testing before leaving the factory, significantly reducing on-site installation time. It eliminates delays caused by factors like inability to open cabinets due to rain or oversight during nighttime construction.
The systems adhere to comprehensive safety measures, ensuring protection at the cell, battery, and system levels. The exclusive battery management system monitors the voltage and operating status of individual cells and modules, balancing battery usage and improving overall system reliability and lifespan.
Delta’s LFP lithium-iron battery system has obtained IEC 62619 certification and successfully completed UL 9540A testing.
