Liquid cooled PCS system, the system mainly includes PCS liquid cooling device, water cooling unit, battery cluster liquid cooling device, water cooling unit inlet is connected to the liquid outlet of PCS liquid cooling device, battery cluster liquid cooling device outlet is connected to the liquid inlet of PCS liquid cooling device. The PCS liquid cooling device is connected to the liquid cooling circuit. When the system is started in winter, the liquid temperature can be heated by the heating of PCS to reduce the power consumption of PTC. In use, the liquid cooling system can cool the PCS device and the battery cluster together.

      The new architecture system of "serial PCS+ liquid cooled battery cabinet" has fine charge and discharge cluster level management, and the discharge capacity of the battery is increased by 7%; Liquid-cooled battery cabinet design, the system temperature difference is less than 3℃, the battery life is increased by 20%, the area is reduced by 15%, and the comprehensive LCOS is reduced by 20%. The cluster level modular addition and replacement of energy storage units reduce the recharge capacity by 9%, the system is highly integrated, the transportation and installation are more convenient, the weak network adaptability is strong, the inertia support and a variety of power grid auxiliary service functions.

             SinoSoar Microgrid, design and development of liquid cooled converter (PCS module), mainly for medium and large energy storage microgrid development of an efficient, high-protection liquid cooled microgrid energy storage inverter
