The feature of this embodiment is that a regulator is provided on the mantissa side v1 to yt> for cooling the inlet of the IIc pond. That is, the purpose of these regulators v1 to vn is to independently control the power of the cooling fluid entering the battery. Fig. 4 is a diagram showing an example of the control method, in which 401 to 401m represent temperature setting positions, and subtraction im411 to 411m takes the deviation from the detected temperature value from the detection level T1 to Tn and calculates the control. The controllers 421 to 42n perform control calculations such as proportionality, integration, and differentiation, and operate the -articulation vi-vn. By performing such control, it becomes possible to always maintain the temperature of each part of the battery at an optimal value.
