To properly operate a cooling fan when cooling a plurality of high-voltage electric apparatuses by a blast from a single cooling fan.
This controller determines whether there is a possibility of a temperature (battery temperature TB, DC-DC converter temperature TD, PDU temperature TP) of a high-voltage component reaching a cooling-requested temperature (#TB2, #TD2, #TP2)being a determination threshold determined that there is the necessity of cooling by cooling fan, or over. This so controls the drive of the high-voltage electric component determined that there is no possibility of reaching the cooling-requested temperature cooperatively as to accelerate the temperature rise of the high-voltage electric component. Thus, this reduces the relative difference of temperature states between the high-voltage electric component determined that there is a possibility of reaching the cooling-requested temperature and the high-voltage electric component determined that there is no possibility.
