Patent ID: 8321296

Claim:
A method of distributing charge capacity to a plurality of electric vehicles in a charging system that includes a solar charge capacity that is generated locally from solar energy, the method comprising at least one processor executing instructions for performing the steps of: determining a requested charge for the plurality of electric vehicles, the requested charge comprising the total energy required to charge the batteries of the plurality of electric vehicles from a current state-of-charge to a desired state-of-charge; calculating a requested charge time, the requested charge time comprising the total charging time required to charge the batteries of the plurality of electric vehicles from the current state-of-charge to the desired state-of-charge; calculating the solar charge capacity, the solar charge capacity comprising the total charging capacity of the charging system via the locally generated solar energy; calculating a charge time capacity, the charge time capacity comprising the available charge time of the charging system; comparing the requested charge to the solar charge capacity; comparing the requested charge time to the charge time capacity; and when a capacity shortage is determined via a finding that the requested charge is greater than the solar charge capacity or the requested charge time is greater than the charge time capacity, auctioning the solar charge capacity to operators of the plurality of electric vehicles.
