SYSTEM FOR CONTROLLING BATTERY CELL TEMPERATURE AND METHOD FOR CONTROLLING SAME

In a system for controlling battery cell temperature and a method for controlling the system, the system includes a planar shape heat transferring unit, a cooling plate, a heating plate, a radiator, a heater and a controller. The planar shape heat transferring unit makes contact with a battery cell. The cooling plate is disposed at a first side of the battery cell to be heat-transferred with the planar shape heat transferring unit. The heating plate is disposed at a second side of the battery cell to be heat-transferred with the planar shape heat transferring unit. The radiator is connected to the cooling passage, to provide a cooled first fluid to the cooling passage. The heater is connected to the heating passage, to provide a heated second fluid to the heating passage. The controller is configured to provide the first fluid or the second fluid.
