Implementations of the present invention contemplate utilizing a communicative infrastructure represented by a telematics unit of an electric vehicle and a telematics service provider (TSP) communicatively coupled to the telematics unit to control an amount of power reserved for a charging event of the vehicle. Specifically, the TSP utilizes information provided by the telematics unit, electrical power utilities, and electrical power metering devices to determine the characteristics of electrical energy available for charging the vehicle. The TSP can utilize the characteristics of the available energy along with additional information, such as charging preferences established by a subscriber of the TSP and vehicle use schedules, to determine an amount of power to reserve for the charging event. The amount of power reserved for the charging event may be determined based on cost, greenhouse gas emissions, a combination thereof, and on other factors.

Optimizing vehicle recharging to maximize use of energy generated from particular identified sources

Implementations of the present invention contemplate using the communication infrastructure represented by a network of telematics units communicatively coupled to a telematics service provider (TSP) to implement procedures designed to curtail the load placed on electricity suppliers by electric vehicles during periods of critically high demand for electricity. The present invention contemplates monitoring charging related information for multiple electric vehicles through the telematics units in those vehicles. The invention further contemplates a request from an energy utility for a response to a critically high demand for electricity and the execution of a demand response program (DRP). The DRPs involve aggregating information from a fleet of the electrically powered vehicles, processing the aggregated information, and issuing instructions to one or more vehicles in the fleet that cause the one or more vehicles to reduce the load they are placing on electricity suppliers through their charging activities.
