AlphaESS releases liquid-cooled ESS for commercial, industrial use
Chinese-headquartered storage manufacturer AlphaESS has announced a new pre-assembled, liquid-cooled energy storage system (ESS) for the commercial and industrial (C&I) market.
In addition to the cooling system, the Storion TB125 system integrates a power conversion system (PCS), energy management system (EMS), battery management system (BMS), lithium iron phosphate (LiFePO₄) battery modules, and fire suppression technology.
“Each TB125 delivers 125 kW / 261 kWh and can be expanded with up to 50 units in parallel, scaling easily to multi-megawatt-hour projects,” the company said in a statement. “With Active Balancing technology for improved cell consistency and a lifespan extension of more than 10%, combined with the AlphaESS intelligent O&M platform, customers can achieve payback in as little as three years. Supporting AC coupling, the TB125 integrates seamlessly with solar PV, the grid, diesel generators, and EV charging stations to maximize energy use and project returns.”
According to AlphaESS, its liquid-cooling system maintains cell temperature differences within 3 C, reducing thermal stress and extending battery life by about 10%. The system operates in ambient temperatures ranging from -20 C to 50 C, tolerates humidity up to 95%, and functions at altitudes of up to 3,000 m. It measures 1,003 mm × 1,500 mm × 2,482 mm and weighs 2.9 t.
“The system features four layers of protection—from cell-level monitoring to full fire suppression—including smoke and temperature detection, water spray, aerosol suppression, and a BESS explosion vent,” the company added. “The TB125 is certified under UL9540A, the industry’s gold standard for fire safety, and built to IP55 standards, making it robust enough for humid, dusty, or otherwise harsh operating environments.”
