Energy storage system

Abstract

The invention relates to an energy storage system which is used for solving the technical problem that energy consumption needed by heat exchange of an energy storage system is high. The energy storage system comprises a prefabricated cabin, an interlayer is arranged in a wall part, a heat exchange coil pipe is arranged in the interlayer, the flow battery is arranged in the prefabricated cabin and comprises an electrolyte heat exchanger, an absorption type cooling unit and a heat management flow path, and the heat management flow path comprises a first circulation loop, a second circulation loop, a third circulation loop and a fourth circulation loop, the fluid is communicated between the absorption type cooling unit and the electrolyte heat exchanger, and the fluid is communicated between the heat exchange coil and the electrolyte heat exchanger; the energy storage system is configured as follows: when the external environment temperature is higher than the normal working temperature of the flow battery, the first circulation loop and the second circulation loop are conducted, and the third circulation loop is cut off; and when the external environment temperature is lower than the normal working temperature of the flow battery, the first circulation loop and the second circulation loop are cut off, and the third circulation loop is conducted.
