Electric vehicle and roadway power system therefore

An electrical vehicle transportation system, comprising:

• an electrical vehicle and a powered roadway system, said electrical vehicle having a power source and a vehicle master control system, said master control system including switching means having electrical power on and off positions, said master control system further including vehicle circuitry having at least a first relay,
• said electrical vehicle further having at least a first front wheel and at least a first longitudinally spaced rear wheel, said first front and first rear wheels being configured to traverse over a roadway surface,
• said powered roadway system including an electrical vehicle engagement system, a roadway control system, roadway control circuitry having at least a first relay, and roadway electrical energy source,
• said electrical vehicle engagement system being in communication with said roadway electrical energy source and including at least two pair first and second pairs of elongated longitudinally and laterally spaced parallel electrically conductive roadway segments, each of said first and second roadway segments having a segment length (S1), said first and second roadway segments being arranged on said roadway surface, said first and second roadway segments including electrically conductive layers having top and bottom surfaces and insulating layers disposed on said conductive layer bottom surfaces,
• a longitudinal spacing (D1)between said first and second roadway segments being a function of first roadway electrical energy source voltage, which is approximately 0.01 inch per volt of the roadway energy source voltage,
• said roadway segment length (SL) being a function of said first front wheel and first rear wheel longitudinal spacing and said roadway segment longitudinal spacing (D1), which is an in-line distance between the front and rear wheels of the vehicle plus 1 ft, minus the roadway segment longitudinal spacing (D1), then divide by two,
• said electrical vehicle including a vehicle power control system, said power source, an independent electrical energy source and an energy harvesting system,
• said vehicle power control system including a hard-wired relay control sub-system, wherein said vehicle control circuitry first relay and said roadway control circuitry first relay are connected in series,
• said vehicle electrical energy source having sufficient electrical energy to power said vehicle power source upon command of said vehicle power control system,
• said electrical energy harvesting system including at least one pair of roadway contacts having first and second ends, said first end of said roadway contacts including an electrically conductive region, said second end of said roadway contacts being releasably and rotatably engaged on each side of said vehicle and spaced apart a distance substantially equal to a lateral spacing of said first and second conductive roadway segments, whereby said vehicle can be positioned on said roadway with said roadway contacts in contact with said electrically conductive layers of at least one pair of said first and second roadway segments and, hence, whereby said vehicle energy harvesting system is coupled to said roadway electrical vehicle engagement system,
• said vehicle energy harvesting system, when coupled to said roadway electrical vehicle engagement system, defining a first vehicle envelope characterized by substantially all electrical energy associated with said coupled vehicle energy harvesting system and roadway electrical vehicle engagement system being substantially contained within an area defined by outer dimensions of said vehicle,
• said vehicle control system being operatively connected to said vehicle electrical energy source and said vehicle energy harvesting system, and in communication with said roadway control system when said vehicle energy harvesting system and roadway electrical vehicle engagement system are coupled,
• said vehicle control system being programmed to release said roadway contacts upon positioning said master control system switching means to said power on position, whereby said vehicle circuitry and said hard-wired relay control sub-system are energized and said vehicle roadway contacts are in contact with at least said first parallel roadway segments,
• said vehicle control system being further programmed to control transfer of electrical energy from said roadway electrical energy source to said vehicle when said vehicle energy harvesting system and roadway electrical vehicle engagement system are coupled, and, in conjunction with said roadway control system and said vehicle hard-wired relay control sub-system, when said vehicle energy harvesting system and roadway electrical vehicle engagement system are coupled, the roadway segments that are disposed within said vehicle envelope are energized,
• said vehicle control system being further programmed to de-energize said first roadway segments in response to a first current flow signal generated by a current transformer and transmitted to said vehicle control system, said current flow signal being generated and transmitted when said roadway contacts are de-coupled from said first roadway segments, transition over said longitudinal spacing between said first and second roadway segments (D1), and coupled to said second roadway segments, whereby said first roadway segments are de-energized prior to said first roadway segments transitioning outside said vehicle envelope when said vehicle is traversing said roadway surface.
