Liquid cooling provides superior thermal uniformity and efficiency compared to air cooling. It reduces temperature gradients between battery cells, extends battery lifespan, supports higher energy densities, and enables safe operation in high-temperature environments, making it ideal for 1MWh+ systems.

Each pack contains 3.2V 280Ah LiFePO₄ cells arranged in modules with integrated liquid cooling plates. Coolant circulates through a closed-loop system with pumps, sensors, and a chiller or liquid-to-air heat exchanger. The system integrates BMS, EMS, fire suppression, and often resides in 20/40-ft containers.

Liquid-cooled BESS systems are ideal for utility-scale renewable integration, frequency regulation, large EV charging hubs, and high-temperature or high-altitude locations. They’re also preferred in dense deployments where airflow is limited or where precise thermal control is critical.

Systems include multi-level BMS protection, leak detection sensors, temperature/flow monitors, smoke and gas detection, and automatic fire suppression (aerosol or NOVEC). The cooling loop uses non-conductive, non-flammable fluids to ensure electrical and thermal safety.

Maintenance includes periodic checks of coolant levels, filter replacement, leak inspection, and pump operation monitoring. Advanced systems support remote diagnostics, predictive alerts, and automated fault isolation to minimize downtime and optimize performance.
