This invention is a convenient system to charge an electric vehicle, or a hybrid vehicle, during its travel on a road. What sets this invention apart, is that the electric charging is done during normal driving on a special road. It is a convenient, automatic charge method, wherein the driver does nothing except driving. Many types of electric vehicles can be charged automatically, with the charging fee being done automatically, by a license plate scanner.
