A control apparatus for a vehicle determines whether to perform either a first control or a second control. In the first control, power is transferred between a power supply facility outside a vehicle and a power storage apparatus during stopping of the vehicle. In the second control, power is transferred between a rotating electric machine and the power storage apparatus through an inverter during traveling of the vehicle. In the first control, the apparatus performs control of the inverter to set a controlled variable to be equal to or less than a first limit value. In the second control, the apparatus performs control of the inverter to set the controlled variable to be equal to or less than a second limit value. The apparatus sets either the first or second limit values to a value suppressing a decrease in a maximum dischargeable power of the power storage apparatus.
