Abstract
A vehicle includes a battery, a rotating electric machine, an electric power conversion device, a charging device, and a control device. When the battery is charged, the charging device supplies direct-current power to a neutral point of the rotating electric machine, and the rotating electric machine and the electric power conversion device boost the direct-current power and supply the power to the battery. During traveling, the control device predicts a traveling time to a charging place, and executes a control that restrains rise in the temperature of a charging group in a case where the predicted traveling time is equal to or shorter than a criterion time and where a condition is satisfied, the condition being a condition that temperatures of the battery, the rotating electric machine and the electric power conversion device that are included in the charging group is higher than a criterion temperature.
