Original Abstract Submitted
A vehicle includes a power storage device, a charging circuit capable of external charging by converting AC power from a power system to DC power and charging the DC power to the power storage device when the vehicle is connected to the power system external to the vehicle, and a controller programming to control the charging circuit. The vehicle includes a detection circuit configured to detect the impedance of the charging path from the power system to the power storage device during external charging. The controller is programmed to switch control of the charging circuit when the impedance of the charging path is higher than the threshold value during external charging, compared to when the impedance of the charging path is lower than the threshold value during the external charging.
