835kWh Energy Storage System

SMT-ESS-CUBE835CE


The 835kWh outdoor battery cabinet, model SMT-ESS-CUBE835CE, is equipped with high-safety, long-life 314Ah lithium iron 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 two parallel 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.

Features

    • ● High-capacity cells and large pack design enhance energy density and reduce cost per Wh.
      ● Precise thermal management strate- gies reduce auxiliary power consump- tion and improve system efficiency.

      ● Multi-level electrical protection, including:Pack-level fuses for overcurrent and short-circuit protection; Cluster-level fault identification and active safety protection; Overcurrent and short-circuit protection on the collection cabinet side; Active protection from the PCS in response to BMS fault reports.
      ● The battery cabinet can be flexibly matched with either a DC-coupled or AC-coupled solution.
