The liquid-cooled cabinet includes state-of-the-art cabinet-level liquid cooling and temperature balancing techniques. With a cell temperature variance of less than 3°C, it enhances the uniformity of cell temperature and prolongs battery lifespan. As a result of the cooling techniques, the ESS is able to benefit from greater energy density. This enhances the economic viability. The cabinet integrates long-life Lithium Ferrous Phosphate battery chemistry, efficient bidirectional-balancing Battery Management System (BMS), high-performance Power Conversion System (PCS), active safety system, smart distribution into one cabinet.
