PROBLEM TO BE SOLVED: To suppress a situation in which an electric power cannot be output to an electric load from only one of batteries B1, B2 of a vehicle.SOLUTION: A vehicle includes a battery B1 to be connected to an electric load via a step-up converter and a battery B2 to be connected to the electric load without using the step-up converter. An ECU calculates a vehicle request output Pv corresponding to actual vehicle speed and accelerator opening (S10), and sets an output Pof the battery B2 to be obtained when a voltage Vof the battery B2 decreases to voltage V+step-up margin α of the battery B1, by use of OCVof the battery 1, OCVof the battery 2, and internal resistance Rof the battery B2, to an upper output limit value Pmax1 of the battery 2 (S11). The ECU sets smaller one of the Pv and the Pmax1 to the output Pof the battery 2 (S12), and sets the Pv-Pto the output Pof the battery B1 (S13). |
