Patent ID: 8614624

Claim:
A method of transferring energy by a first unit in an environment further including a second unit, wherein at least one of the first and second units is mobile, wherein the first unit has a subscription to a first backend platform, said first unit comprising (i) a first meter for measuring energy exchanged with an external power source and/or an external power consumer, (ii) a first control box, (iii) a switch which allows interruption of energy exchange between the first and second units, and (iv) a transceiver operative to communicate with the first backend platform, the method comprising: coupling a power line to the first unit, said power line being further coupled to the second unit; receiving, by the first unit, a request for transferring energy between the first and second units, said request having originated at a second control box of the second unit; unbarring, by the first control box, the switch in response to authentication of the first and the second units to each other; receiving by the first control box, an indication of an amount of the transferred energy; transmitting energy transfer data toward the first backend platform, said energy transfer data comprising data about an amount of exchanged energy measured by the first meter.
