Abstract
A battery pack apparatus including at least one battery assembly, a plurality of medium feeding parts for adjusting temperatures of the battery assembly, at least one temperature detector, a storage unit, and a controller. The storage unit stores a relation between a temperature of the battery assembly and a revolution level of the medium feeding parts. The controller reads out a revolution level corresponding to the detected temperature of the battery assembly from the storage unit, and allocates the revolution level to the medium feeding parts. The controller changes the value of the revolution levels allocated to the respective medium feeding parts based on the allocated revolution levels so that any one of the revolution levels of the plurality of the medium feeding parts is different from the other revolution levels thereof, and controls the plurality of medium feeding parts at changed revolution levels.
