Abstract

A vehicular charge apparatus for externally charging an in-vehicle battery of a vehicle includes a charger. The charger includes an in-charger detection section, which detects a charge needed state of a subject vehicle prior to a charge connection of a charger connector of the charger to an in-vehicle charge inlet of the subject vehicle. In the charge needed state, an electric charge is necessary for the vehicle. When the charge needed state of the subject vehicle is determined, a charger controller of the charger begins a charge preparation operation needed in the charger while transmitting charge information that indicates that the subject vehicle is in the charge needed state via an in-charger communicator to an in-vehicle communicator. When the in-vehicle communicator receives the charge information, a charge preparation section of the subject vehicle begins a charge preparation operation necessary in the subject vehicle.

Claims

1. A vehicular charge apparatus including a charger for supplying an electric power to charge an in-vehicle battery mounted in a vehicle after a user completes a charge connection, which connects a charger connector of the charger with an in-vehicle charge inlet of the vehicle,

the charger comprising:

a detection section that detects, of the vehicle, a charge needed state in which an electric charge is needed for the vehicle, prior to completing the charge connection of the charger connector with the in-vehicle charge inlet;

an in-charger communicator that communicates with an in-vehicle communicator in the vehicle; and

an in-charger controller that controls an operation of an electric charge,

wherein

when the detection section detects the charge needed state of the vehicle, the in-charger controller executes a charge preparation operation necessary in the charger, and transmits charge information, which indicates that the vehicle is in the charge needed state, via the in-charger communicator to the in-vehicle communicator, causing an in-vehicle charge preparation section in the vehicle to begin a charge preparation operation necessary in the vehicle when the in-vehicle communicator receives the charge massage from the in-charger communicator.

2. The vehicular charge apparatus according to claim 1, wherein:

the charger further comprises a connector holder that holds the charger connector when the charger connector is not used; and

when the charger connector is removed from the connector holder, the detection section detects the charge needed state.

3. The vehicular charge apparatus according to claim 1, wherein:

the charger further comprises a sensor which recognizes a presence of the vehicle within a predetermined distance; and

when the sensor recognizes the presence of the vehicle within the predetermined distance, the detection section detects the charge needed state.

4. The vehicular charge apparatus according to claim 3, wherein

further when the in-charger communicator receives from the in-vehicle communicator information indicating that the vehicle belongs to an electric vehicle, the detection section detects the charge needed state of the vehicle.

5. The vehicular charge apparatus according to claim 1, wherein

when the in-charger communicator receives from the in-vehicle communicator information indicating that an in-vehicle charge request switch in the vehicle is turned into an ON state by the user to request a start of an electric charge, the detection section detects the charge needed state of the vehicle.

6. The vehicular charge apparatus according to claim 1, wherein:

the charger further comprises an in-charger charge request switch for the user to request a start of an electric charge; and

when the in-charger charge request switch is turned into an ON state by the user, the detection section detects the charge needed state of the vehicle.

7. The vehicular charge apparatus according to claim 1, wherein:

the charger further comprises a verification section to verify information belonging to the user; and

when the verification section successfully verifies the information belonging to the user, the detection section detects the charge needed state.

8. The vehicular charge apparatus according to claim 1, wherein

the charge preparation of the in-vehicle charge preparation section includes at least one of:

(i) applying a parking brake of the vehicle;

(ii) shifting a selector for transmission of the vehicle to a parking position;

(iii) opening of a lid portion of the charge inlet of the vehicle;

(iv) switching the vehicle into a state where an electric charge is enabled;

(v) turning electrical devices mounted in the vehicle into an OFF state; and

(vi) turning an illuminator in the charge inlet of the vehicle into a lighting state.

9. The vehicular charge apparatus according to claim 1, wherein the charge preparation executed by the in-charger controller includes at least one of:

(i) switching a charge link connected from a power source to the charger connector into a hot-link state which enables the charge for the vehicle; and

(ii) turning an illuminator in the charger connector into a lighting state.

10. The vehicular charge apparatus according to claim 1, wherein

when the detection section detects the charge needed state of the vehicle, the in-charger controller transmits via the in-charger communicator the charge information to a charge facility, which includes one of (i) a charge station housing the charger and (ii) a home of the user, causing the charge facility to begin a charge preparation necessary in the station.

13. The vehicular charge apparatus according to claim 2, wherein the in-charger controller warns the user in cases that a predetermined duration elapses without the charger connector connected to the in-vehicle charge inlet since the charger connector is removed from the connector holder.

14. The vehicular charge apparatus according to claim 2, wherein in cases that the charger connector is not held in the connector holder after the electric charge is completed, the in-charger controller transmits via the in-charger communicator to the in-vehicle communicator a vehicle start-up prohibition instruction to prohibit a start-up of the vehicle while warning the user.

15. The vehicular charge apparatus according to claim 1, wherein when verifying information belonging to the user is not executed by the user after the electric charge is completed, the in-charger controller transmits via the in-charger communicator to the in-vehicle communicator a vehicle start-up prohibition instruction to prohibit a start-up of the vehicle while warning the user.

16. A method for supplying from a charger an electric power to charge an in-vehicle battery mounted in a vehicle after a user completes a charge connection, which connects a charger connector of the charger with an in-vehicle charge inlet of the vehicle,
