PROBLEM TO BE SOLVED: To provide a temperature controller of a battery pack, capable of suppressing problems due to adhesion of dew condensation to the metal terminal of a secondary battery in a battery pack housing the secondary battery and a cooler.SOLUTION: An air conditioning controller of a battery pack, mounted on a vehicle, and performing air conditioning control in a battery pack housing a secondary battery for supplying power to a motor as a drive source and a cooler for cooling the secondary battery, includes a dew condensation occurrence temperature calculation unit for calculating the dew condensation occurrence temperature on the basis of the temperature and humidity of air in the battery pack, a dew condensation prevention control execution determination unit for determining whether or not the mount of water vapor in the battery pack is copious, and a dew condensation prevention control unit for controlling the cooler so that the temperature of air in the battery pack is maintained higher than the dew condensation occurrence temperature, when a determination is made that the mount of water vapor is copious.SELECTED DRAWING: Figure 10 |
