Patent ID: 8676636

Claim:
A system for managing electric energy exchange devices for charging and discharging of vehicles, comprising: a processor configured to: receive a set of predefined parameters for electric energy exchange for a vehicle using an electric energy exchange device for a time increment, wherein the set of predefined parameters comprises price levels associated with loyalty levels of customers shopping at a partner company; receive a set of transaction specific parameters; and determine a price for electric energy exchange based at least in part on the set of predefined parameters and the set of transaction specific parameters; provide the price for electric energy exchange to a point of sale device at the partner company; determine whether a wait time has elapsed, for a subset of the electric energy exchange devices, until a next allowed charge and in the event that the wait time has not elapsed for the subset of the electric energy exchange devices, indicate that the electric energy exchange is not allowed, wherein the number of electric energy exchange devices in the subset of the electric energy exchange devices is less than the total number of the electric energy exchange devices; determine whether a customer shopping history at the partner company meets predefined parameters for free electric energy exchange; in the event the customer shopping history at a partner company meets the predefined parameters for free electric energy exchange, provide indication of free electric exchange; and a memory coupled to the processor and configured to provide the processor with instructions.
