System for controlling battery cell temperature and method for controlling same

A system for controlling battery cell temperature, the system comprising:

• a planar shape heat transferring unit contacted with a battery cell;
• a cooling plate disposed at a first side of the battery cell to be heat-transferred with the planar shape heat transferring unit and having a cooling passage formed inside of the cooling plate;
• a heating plate disposed at a second side of the battery cell to be heated with the planar shape heat transferring unit and having a heating passage formed inside of the heating plate;
• a radiator connected to the cooling passage and configured to provide a cooled first fluid to the cooling passage;
• a heater connected to the heating passage and configured to provide a heated second fluid to the heating passage;
• a moving unit having a first side connected to the cooling plate and a second side connected to the heating plate and configured to move both of the cooling plate and the heating plate at the same time;
• and
• a controller configured to provide the cooled first fluid or the heated second fluid by comparing a measured temperature of the battery cell with a predetermined temperature of the battery cell,
• wherein the controller is configured to select:
• a first mode in which the cooled first fluid is provided to the cooling passage, when the measured temperature is higher than the predetermined temperature;
• and
• a second mode in which the heated second fluid is provided to the heating passage, when the measured temperature is lower than the predetermined temperature, and
• wherein the moving unit is configured to move:
• when the first mode is selected, the cooling plate to contact with the planar shape heat transferring unit and the heating plate not to contact with the planar shape heat transferring unit, and
• when the second mode is selected, the heating plate to contact with the planar shape heat transferring unit and the cooling plate not to contact with the planar shape heat transferring unit.
