An ECU performs a program including a step of notifying a system main relay shut-off signal to a high-voltage system using equipment (S200) when a system main relay shut-off demand due to a HV system failure is generated (YES in S100), a step of shutting off the system main relay (S700) when a high voltage shut-off acknowledging signal from the high-voltage system using equipment is not unreceived (NO in S300), a step of shutting off the system main relay (S700) when a high voltage shut-off acknowledging signal from the high-voltage system using equipment is unrecived (YES in S300) and a current value in a high voltage circuit is more than the predetermined threshold (NO in S500), and a step of shutting off the system main relay (S700) when the current value in the high voltage circuit is not more than the predetermined threshold (YES in S500) and the predetermined period of time has elapsed from the occurrence of a HV system malfunction (YES in S600).
