The 835kwh outdoor battery cabinet, model SMT-ESS-CUBE835CE,is equipped with high-safety,long-life 314Ah lithiumiron phosphate (LFP) cells. The cells are arranged in a 1P104S configuration to form standardized battery packs, with four packs in series forming a battery cluster. The outdoor cabinet contains twoparallel battery clusters. The battery pack features a plate-type liquid cooling design, with the liquid cooling plate integrated into the lower part of the pack and connected to the liquid cooling unit via external piping. The optimized cooling plate and piping design enable efficient battery thermal management under various Operating conditions. The cabinet's structural waterproof and dustproof design, multiple electrical protection designs, multi-lev-el BMS architecture, and independent fire detection and extinguishing devices ensure long-term safe operation of the outdoor cabinet from mechanical, electrical, and fire protection aspects.
