1. A control apparatus for a vehicle that includes a power storage apparatus, an inverter that is electrically connected to the power storage apparatus, and a rotating electric machine that is electrically connected to the inverter, the control apparatus comprising one or more electronic control units configured to:
determine whether to perform either a first control in which the power storage apparatus is charged from a power supply facility external to the vehicle during stopping of the vehicle, or a second control in which electric power is transferred between the rotating electric machine and the power storage apparatus through the inverter during traveling of the vehicle;
perform, in response to determining that the first control is being performed, control of the inverter to set a controlled variable that is either an electric power or a current and that is transferred between the power supply facility and the power storage apparatus to be equal to or less than a first limit value, and perform, in response to determining that the second control is being performed, control of the inverter to set the controlled variable that is either the electric power or the current and that is transferred between the rotating electric machine and the power storage apparatus to be equal to or less than a second limit value;
with a period from start of traveling of the vehicle after completion of the first control until the first control is started again being a single traveling cycle,
predict, before start of charging of the power storage apparatus when an execution instruction for a current first control is issued, a first temperature that is a temperature of the power storage apparatus when the current first control in which the power storage apparatus is charged at a prescribed power is assumed to be completed, based on an average time from start to completion of the first control and an average charging power of the power storage apparatus from the start to the completion of the first control,
predict a second temperature that is a temperature of the power storage apparatus when a next single traveling cycle that is performed after the current first control is assumed to be completed, based on the predicted first temperature, an average discharging power of the power storage apparatus in the single traveling cycle, and an average time that is required for the single traveling cycle,
determine whether the predicted second temperature is equal to or less than a requested temperature that is the temperature of the power storage apparatus that sets a maximum dischargeable power of the power storage apparatus to a traveling requested power of the vehicle, and decrease the prescribed power that is used to predict the first temperature until the predicted second temperature, which is based in part on the predicted first temperature, is determined to be equal to or less than the requested temperature, and
set the first limit value used for charging in the first control to the prescribed power that results in the predicted second temperature is being determined to be equal to or less than the requested temperature.
