A system for managing electric energy exchange devices is disclosed. The system comprises a processor and a memory. The processor is 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. The set of predefined parameters comprises price levels associated with levels of customers. The processor is further configured to receive a set of transaction specific parameters. The processor is configured to 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. The processor is configured to determine whether a level of a customer meets predefined parameters for free electric energy exchange. The processor is configured to, in the event the level of the customer meets the predefined parameters for free electric energy exchange, provide for free electric exchange.
