KETEP 세계에너지시장정보

An energy storage system, comprising:
at least one battery pack further comprising:
a cooling plate and
a battery cell, wherein the cooling plate is configured to contact the battery cell to transfer heat energy; and
a thermal management system further comprising:
a control unit,
a compressor,
a heat exchanger, and
at least one first control valve, wherein an outlet of the compressor is connected to the heat exchanger, the heat exchanger is connected to a first inlet and an outlet of the cooling plate in the at least one battery pack through the at least one first control valve, a second inlet and outlet of the cooling plate in the at least one battery pack is connected to an inlet of the compressor, and the control unit is configured to, when a battery cell temperature of the at least one battery pack is greater than or equal to a first temperature threshold;
control the compressor to compress a thermal management medium, so that a thermal management medium flows into the heat exchanger, and
control opening of the at least one first control valve to control the thermal management medium to flow into the cooling plate in the at least one battery pack to exchange heat with the battery cell, to decrease the battery cell temperature.
