Abstract

Provided is a practical plug-in hybrid vehicle or an electric vehicle as well as a charge system, a fuel consumption measurement system, and an environment protection system for the vehicles. The charge system includes an electric power source charging a vehicle having a battery, a power supply unit for supplying electric power from the electric power source to the vehicle, and a power cable communication unit for performing power cable communication concerning the vehicle and the charging via the power supply unit. The vehicle includes a fuel tank for receiving oil from outside, a storage unit for storing oil supply information, a power source which consumes the fuel in the fuel tank and provides a travel power, a travel distance information acquisition unit, and a control unit which automatically calculates the fuel consumption according to the oil supply information in the storage unit and the travel distance information in the travel distance acquisition unit.

Claims

1. A charge system for a vehicle comprising:

an electric power source which charges a vehicle having a battery;

a power supply unit which leads electric power from the electric power source to the vehicle; and

a power cable communication unit which performs power cable communication with the vehicle about the charging via the power supply unit.

2. A charge system for a vehicle according to claim 1, comprising a power supply switching unit which determines whether or not to supply electric power from the electric power source to the power supply unit, wherein the power supply switching unit is controlled in accordance with communication by the power cable communication unit with the vehicle.

3. A charge system for a vehicle according to claim 2, wherein the power supply switching unit enables the power cable communication unit to communicate with the vehicle regardless of whether or not electric power is supplied to the power supply unit.

4. A charge system for a vehicle according to claim 2, wherein the power supply switching unit suspends starting of the power supply until a predetermined time slot comes even if the power supply unit is in a state capable of charging the vehicle.

5. A charge system for a vehicle according to claim 1, comprising a decision unit which decides that the power supply unit is left in an abnormal state that is not a vehicle charging state.

6. A charge system for a vehicle according to claim 1, wherein the power cable communication unit transmits power supply information to the vehicle via the power supply unit.

7. A charge system for a vehicle according to claim 1, wherein the power cable communication unit transmits information for payment of electric fee bill to the vehicle.

8. A charge system for a vehicle according to claim 1, further comprising a fuel storage which supplies fuel to a vehicle having a fuel tank, and a fuel supply unit which leads fuel from the fuel storage to the vehicle.

9. A charge system for a vehicle according to claim 8, wherein the power cable communication unit transmits oil supply information to the vehicle via the power supply unit, for fuel consumption calculation.

10. A charge system for a vehicle according to claim 8, comprising a refueling preparation detection unit which detects whether or not the fuel supply unit is in a refueling preparation state, a power supply preparation detection unit which detects whether or not the power supply unit is in a power supply preparation state, and a controller which changes power supply situation to the vehicle when the power supply preparation detection unit detects the power supply preparation state depending on whether or not the refueling preparation detection unit detects the refueling preparation state.

11. A charge system for a vehicle according to claim 8, comprising an abnormal detection unit which detects an abnormal state of the power supply unit, and a controller which disables the fuel supply unit to supply fuel when the abnormal detection unit detects an abnormal state of the power supply unit.

12. A charge system for a vehicle according to claim 11, wherein the power supply unit and the fuel supply unit are structured as an integrated cable.
