Abstract

The electric car is practically entirely covered in solar cells. Further, transparent solar cells are incorporated into the windshield and into the other windows of the car. The various features of the car give it considerable autonomy.

Claims

1-6. -6. (canceled)

7. An electrically powered motor vehicle including at least one electric motor, a rechargeable battery for supplying the motor with electricity and a passenger compartment, the vehicle further including a body made of opaque material and forming a case enclosing the electric motor and the battery as well as the passenger compartment, and further including a windshield made of transparent material and arranged in an aperture in the body, the opaque material in which the body is made including photovoltaic cells arranged on the sides and top of the vehicle so as to generate electricity when the vehicle exterior is exposed to solar radiation, the electricity provided by the photovoltaic cells being supplied to the rechargeable battery and/or the motor, the transparent material in which the windshield is made having transparent photovoltaic cells electrically connected to the rechargeable battery and/or the motor, wherein the rechargeable battery can store at least 160 Wh electric power per kg and be charged to up to 80% of its capacity within 10 minutes, and wherein windows fitted with transparent photovoltaic cells, are arranged in a plurality of apertures in the body, the photovoltaic cells on the sides and top of the body, as well as the photovoltaic cells in the windows, being divided into several areas in which the cells share approximately the same orientation.

8. The electrically powered motor vehicle according to claim 7, wherein the rechargeable battery can store at least 200 Wh of electric power per kg.

9. The electrically powered motor vehicle according to claim 7, wherein the photovoltaic cells carried by the body have a yield of at least 40%.

10. The electrically powered motor vehicle according to claim 9, wherein said photovoltaic cells have a yield of at least 50%.

11. The electrically powered motor vehicle according to claim 7, wherein the rechargeable battery can be charged to up to 80% of its capacity within one minute.

12. The electrically powered motor vehicle according to claim 7, wherein the electric motor can also operate as a generator and in that said motor is for charging the battery when the vehicle is braking.

13. The electrically powered motor vehicle according to claim 8, wherein the photovoltaic cells carried by the body have a yield of at least 40%.
