CHARGE CONTROLLER FOR ELECTRICALLY POWERED VEHICLE
First Claim
1. A charge controller for an electrically powered vehicle, configured to enable charging of a power storage device mounted on the electrically powered vehicle from a power source outside of the vehicle, comprising:
- a charging cable for connecting said power source to said electrically powered;
vehicle;
a charging inlet provided on said electrically powered vehicle, configured to be connectable to said charging cable; and
a control device provided on said electrically powered vehicle, for receiving a control signal indicating information of electric power supplied to said electrically powered vehicle, transmitted from said charging cable;
whereinsaid charging cable includesa charging connector configured to be connectable to said charging inlet,a plug configured to be connectable to said power source, andan electric wire unit provided between said charging connector and said plug;
said electric wire unit includesa power line for supplying electric power from said power source to said electrically powered vehicle,a control line for communicating said control signal, anda ground line connected to a chassis ground; and
said control device includes a switch for switching whether to supply or not to supply a voltage to said control line, and detects state of connection of said charging cable and state of said control line based on potential of said control signal in accordance with presence/absence of voltage supply to said control line line.

Abstract
A charging connector includes a lock button for locking the charging connector in a charging inlet, and a limit switch for electrically connecting a control pilot line and a ground line to each other in response to an operation of the lock button. The vehicle inlet includes a switch circuit for selectively connecting the control pilot line and the ground line with a resistance circuit, depending on whether a charging lid is open or closed. A CPU is configured to be able to supply a voltage to the control pilot line, and based on a potential of a control signal in accordance with presence/absence of voltage supply to the control pilot line, it detects the state of connection of a charging cable and the state of control pilot line.
