Abstract:
1. A cooling device of a power supply formed with a plurality of electricity storage blocks, comprising: a plurality of cooling fans respectively provided corresponding to said electricity storage blocks to supply a cooling medium to said electricity storage blocks; a plurality of motors respectively driving said cooling fans; temperature detection means for detecting a temperature of each of said electricity storage blocks; calculation means for calculating a desired value of a driving voltage of each of said motors based on said temperature of each of the electricity storage blocks detected; rotation number detection means for detecting a rotation number of each of said motors; operation means for performing an operation of a calculated value of the driving voltage of each of said motors based on said rotation number detected; and control means for controlling each of said motors based on a difference between said desired value and said calculated value.
