Soft package battery thermal management system and operation method thereof

The invention provides a soft package battery thermal management system and an operation method thereof, and belongs to the technical field of soft package battery thermal management. The system comprises a cell box body, wherein an isolation part is arranged in the battery box body and divides a cavity in the battery box body into an upper cavity and a lower cavity; a heat exchange unit which comprises a first heat exchanger and a second heat exchanger; a liquid cooling unit; a temperature detection unit; a heating unit and a control unit. A plurality of storage parts are arranged on the lower surface of the lower cavity, the storage parts penetrate through the isolation part to the upper cavity, empty grooves matched with the soft package batteries are formed in the storage parts, and the first heat exchanger is fixedly connected to one side of the upper cavity; and the second heat exchanger is arranged at the ventilation place of the battery box body. According to different temperature conditions of the ba
