1. A system for a vehicle-to-vehicle (V2V) charging service for plug-in electric vehicles (PEVs), the system comprising:
a real-time server (RTS) configured to wirelessly communicate with a plurality of communication devices associated with individual PEVs having membership in the V2V charging service and provide to the plurality of communication devices real-time positions of at least some of the individual PEVs on a map of a terrain;
a first communication device associated with a first PEV from the individual PEVs and configured to wirelessly transmit, via the RTS, to at least one of the communication devices associated with the remaining individual PEVs, a request for an amount of electrical energy to charge the first PEV; and
a second communication device associated with a second PEV from the individual PEVs and configured to wirelessly transmit, via the RTS, to the first communication device an offer to dispense from the second PEV to the first PEV the amount of electrical energy requested by the first communication device;
wherein:
the first communication device is further configured to wirelessly transmit, via the RTS, to the second communication device an acceptance of the offer to dispense the requested amount of electrical energy and thereby implement the charging service; and
at least one of the first communication device and the second communication device is further configured to wirelessly transmit, via the RTS, an inquiry to the other of the first communication device and the second communication device, whether the respective first PEV or second PEV is in possession of a charging cable assembly for electrically connecting the first PEV to the second PEV to charge the first PEV from the second PEV.
