CHARGING CONTROL APPARATUS FOR VEHICLE AND VEHICLE
First Claim
Patent Images
1. A charging control apparatus for 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:
- an EVSE controller provided outside said vehicle and configured to be capable of generating a pilot signal whose potential is manipulated on said vehicle side to allow recognition of a state of said vehicle, and sending said pilot signal to said vehicle;
a potential manipulating circuit mounted on said vehicle, connected to a control pilot line through which said pilot signal from said EVSE controller is transmitted, and configured to be capable of reducing the potential of said pilot signal to a prescribed potential in accordance with the state of said vehicle; and
a resistance element provided between said control pilot line and a ground node and closer to said EVSE controller with respect to a predetermined area where a break in said control pilot line can be detected, and for lowering a potential of said control pilot line to said prescribed potential when an abnormality in said pilot signal is sensed in said vehicle.

Abstract
An EVSE controller generates a pilot signal and sends the pilot signal to a vehicle. A resistance circuit is connected to a control pilot line through which the pilot signal is transmitted, and is configured to be capable of reducing the potential of the pilot signal to a prescribed potential in accordance with a state of the vehicle. A pull-down resistance and a switch are serially connected between the control pilot line and a ground line. A CPU turns on the switch when sensing an abnormality in the pilot signal.
