The prefabricated modular energy storage E-House is an integrated containerized energy storage system that combines battery modules, Battery Management System (BMS), Power Conversion System (PCS), thermal management system, and Energy Management System (EMS). Centered around high-capacity lithium iron phosphate (LFP) battery packs, it achieves efficient energy storage and discharge through the integration of electrical, fire protection, thermal insulation, temperature control, ventilation, emergency escape, and dynamic environmental monitoring systems.
