摘要： A vehicle includes an electrical component electrically connected to a transmission path of supply electric power, a temperature sensor configured to detect a temperature of the electrical component, a control device configured to suppress the supply electric power when the temperature detected by the temperature sensor is equal to or higher than a threshold temperature, as compared with a case where the temperature detected by the temperature sensor is lower than the threshold temperature. The control device is configured to lower the threshold temperature when the external charging is executed again after the external charging is stopped, as compared with a case before the external charging is stopped.
