A Power Monitoring and Control System to minimize electricity demand costs associated with Electric Vehicle charging stations

Abstract

The impact of Battery Electric Vehicle (BEV) charging on the electrical demand of a commercial / industrial energy consumer is examined. A Power Monitoring and Control System (PMCS) is introduced as a method to limit the disincentive to large scale BEV adoption resulting from increased demand costs associated with uncontrolled BEV charging. Reductions in added costs of up to 90% are possible with the incorporation of an intelligent charge control system. Additionally, the PMCS enables transformative charge sharing topologies, including Vehicle to Grid (V2G) and Vehicle to Vehicle (V2V), as solutions for peak shifting and demand response techniques during high demand periods.
