An HV_ECU executes a program including a step (S102) of determining whether a charging cable is connected to a power supply external to the vehicle when a connector signal CNCT output in the case where the charging cable is connected to an inlet of the vehicle is input to the vehicle (YES in S100); and a step (S132) of determining whether a malfunction occurs in a charger mounted in the vehicle when the charging cable is not connected to the power supply (NO in S102).
