  • Patent number: 7767354
    Abstract: In an ECU, a coolant fan performs cooling operation such that a control DUTY value is limited by a control DUTY value according to tolerable noise level of the cooling fan based on a vehicle speed in a case in which the temperature in the high-voltage battery is lower than a predetermined limitation for highest temperature. In a case in which the temperature in the high-voltage battery is higher than the predetermined limitation for highest temperature, the cooling fan performs the cooling operation by using an energy storage device cooling operation requirement value and an IPU cooling operation requirement value such that performance in the high-voltage battery is not affected. By doing this, a temperature controlling apparatus for batteries in which it is possible to cool the battery and solve temperature difference among a plurality of batteries can be provided.
