2.5MW/5MWh Liquid Cooling Energy Storage System Technical Proposal

This technical proposal from Anhui Lvwo Circular Energy Technology Co., Ltd. details a 2.5MW/5MWh liquid cooling energy storage system designed for grid peak shaving, frequency regulation, backup power, and reactive power compensation. The system uses a non-walk-in 20GP container housing LFP batteries with 314Ah cells configured in 1P52S modules and 1P416S clusters, totaling 12 racks for 5.016MWh capacity. It includes a BMS, power distribution, fire protection, DC bus, thermal management, and lighting systems. The liquid cooling maintains battery temperature between 10–35°C for optimal performance and longevity. The system connects to a 2500kW PCS for bidirectional energy conversion, forming a complete energy storage unit. Safety features include comprehensive fire protection, video surveillance, access control, and alarms. The design emphasizes reliable operation, easy installation, and maintenance, supporting various grid services and emergency power needs.
