A system which can efficiently control the temperature of the battery module, and also can easily control the temperature in the intense environment by actively adapting the exterior environment. The system for controlling temperature of a secondary battery module includes a housing receiving a plurality of unit batteries. The housing has an inlet and an outlet. A heat transfer member is in contact with the unit batteries. The heat transfer member has a portion exposed to a heat transfer medium duct formed inside the housing, and a temperature controller is mounted in the heat transfer member to control temperature of the unit batteries.
