250kW-522kWh Outdoor Liquid-Cooled Lithium Battery Energy Storage System

The 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system is engineered for businesses that demand high power output and long-duration capacity in a single, weatherproof enclosure. By pairing a 250 kW power conversion system with 522 kWh of usable lithium-ion storage, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system delivers four hours of continuous discharge at rated power, making the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system ideal for peak-shaving, tariff arbitrage and micro-grid support. Unlike conventional air-cooled cabinets, the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system uses a non-conductive dielectric fluid that circulates through every battery module, keeping cell temperature deviation below 2 °C across the entire 522 kWh pack. This thermal precision extends cycle life beyond 8 000 cycles and allows the 250kW-522kWh outdoor liquid-cooled lithium-ion battery energy storage system to operate safely in ambient conditions from –30 °C to +55 °C without derating.
