In an electric vehicle having a plurality of MG units (29, 30) each including an AC motor (13, 14) and an inverter (27, 28), a control apparatus (37) executes system voltage stabilization control to suppress variations in a system voltage by adjusting an input power of a first MG unit (29) or a second MG unit (30) so as to reduce the difference between a target value and detected value of the system voltage. In execution of this control, either one or both of the MG units is selected by a selector (69) by using information on the first MG unit and the second MG unit. The system voltage stabilization control is executed on the selected MG unit. Alternatively, the control apparatus (37) may execute the system voltage stabilization control by selecting a voltage boosting converter (21).
