PROBLEM TO BE SOLVED: To provide a secondary battery temperature-increasing control apparatus capable of efficiently attaining a target calorific value in a range not exceeding upper and lower limits of voltage of the secondary battery.SOLUTION: An ECU determines whether or not ripple current is within a target range (S50). When determining that the ripple current is not within the target range (NO at S50), the ECU determines whether or not the ripple current is beyond the target range (S80). Then, when determining that the ripple current is smaller than the target range (NO at S80), the ECU decreases a carrier frequency of a voltage-boosting converter forming a ripple generation section (S90). On the other hand, when determining that the ripple current is beyond the target range (YES at S80), the ECU increases the carrier frequency of the voltage-boosting converter (S100). |
