Systems and methods for controlling for distributing power to electric vehicles. The system includes a vehicle charging key (VCK) that is operable to communicate with both a vehicle and a utility communications network. The VCK includes a processor, a memory, and one or more radios for communicating with the vehicle and the utility communications network. The VCK receives information from the vehicle, such as location information and vehicle battery state-of-charge (SOC) information, and transmits the information to a back office system (BOS), such as a utility provider or a credit card company. The BOS generates utility pricing or charging information based on, for example, time of day, and transmits the utility pricing information back to the VCK. A transaction module of the VCK receives payment information from a user that includes a payment selection. The payment selection includes a payment type (e.g., credit card, prepaid account, utility account, etc.). The VCK transmits the payment information to the BOS, and the BOS responds with a charge authorization signal.
