A liquid-based cooling energy storage technology, primarily designed to address heat dissipation challenges in large-scale energy storage applications, thereby improving both efficiency and safety. Its core principle involves the circulation of coolant within or around the energy storage batteries or equipment, absorbing heat and transferring it to a cooling unit, thus enabling effective temperature control of the energy storage system. This prevents performance degradation due to overheating and reduces the risk of thermal-related safety incidents.
