1. An apparatus for activating a system of a vehicle configured to be capable of charging a vehicle-mounted power storage device for driving the vehicle from a power supply external to the vehicle, comprising:
- a signal generating circuit configured to be capable of generating a connection signal indicating connection between said vehicle and a charging cable through which electric power is supplied from said power supply to said vehicle;
an EVSE controller provided outside said vehicle and configured to be capable of generating a pilot signal whose pulse width is modulated based on a magnitude of a rated current that can be supplied to said vehicle through said charging cable and sending said pilot signal to said vehicle;
an activation controller mounted on said vehicle for activating the system of said vehicle in accordance with a system activation operation by a user when travel of the vehicle is requested, and for activating said system in accordance with any one of said connection signal and said pilot signal when charging of said power storage device from said power supply is requested; and
a signal manipulating circuit mounted on said vehicle and configured to be capable of notifying said EVSE controller to provide said pilot signal in a non-pulsed manner until said system is activated by said activation controller, by manipulating a potential of said pilot signal.

Abstract
Until a vehicle system is activated, a switching circuit outputs a pilot signal to an OR circuit. As a result, lowering of the potential of the pilot signal caused by a resistance circuit is avoided, and the pilot signal is provided in a non-pulsed manner. A power supply CPU is activated in accordance with any one of a connector signal and the non-pulsed pilot signal. When the vehicle system is activated, the switching circuit switches an output destination of the pilot signal to the resistance circuit.

8. A method for activating a system of a vehicle configured to be capable of charging a vehicle-mounted power storage device for driving the vehicle from a power supply external to the vehicle, comprising the steps of:
-
activating the system of said vehicle in accordance with a system activation operation by a user when travel of the vehicle is requested; activating said system in accordance with any one of a connection signal indicating connection between said vehicle and a charging cable through which electric power is supplied from said power supply to said vehicle, and a pilot signal which is generated by an EVSE controller provided outside the vehicle and whose pulse width is modulated based on a magnitude of a rated current that can be supplied to said vehicle through said charging cable, when charging of said power storage device from said power supply is requested; and notifying said EVSE controller to provide said pilot signal in a non-pulsed manner until said system is activated, by manipulating a potential of said pilot signal in said vehicle. - View Dependent Claims (9, 10, 12)
