Claim 5:
6. A vehicle-to-vehicle power transfer system for use between a first vehicle and at least a second vehicle, the system comprising:
an electric power system disposed in each of the first and second vehicles, the electric power system having a pair of transceivers associated with each of the first and second vehicles, the electric power system configured to provide electrical drive power to a vehicle drive system for propulsion of the associated vehicle; and
a power transfer system having an RF transmission line extending a first section between the first vehicle and the second vehicle and further extending a second section beyond the first vehicle and a third section beyond the second vehicle, the power transfer system configured to transfer electric power from at least the electric power system of the first vehicle to the electric power system of the second vehicle along the RF transmission line using the pair of transceivers of each of the first and second vehicles, the pair of transceivers of the first vehicle being represented by a first voltage source and a second voltage source, the pair of transceivers of the second vehicle being represented by a third voltage source and a fourth voltage source, the first, second, third, and fourth voltage sources operably coupled to the RF transmission line, the power transfer system configured to spatially direct the electric power from the electric power system of the first vehicle to the electric power system of the second vehicle while simultaneously minimizing transfer of the electric power beyond the first vehicle and the second vehicle by choosing a phase angle between the second voltage source of the first vehicle and the third voltage source of the second vehicle to facilitate transfer of the electric power along the first section and by choosing a phase angle between the first voltage source and the second voltage source to minimize transfer of the electric power along the second section and a phase angle between the third voltage source and the fourth voltage source to minimize transfer of the electric power along the third section.
