Electric Vehicle Charging Technologies Analysis and Standards

This project has evaluated the technologies and standards associated with Electric Vehicle Service Equipment (EVSE) and the related infrastructure, and the major cost issue related to electric vehicle (EV) charging -- the cost of utility power. The technology assessment report evaluated safety standards for infrastructure, highway and vehicles and the barriers and challenges of deploying an expanded network of EV charging stations. The report also made recommendations to help standardize and expedite EVSE infrastructure and charging network deployment. For the cost analyses, the issue of demand charges for utility power are examined for two case studies – one assumes that there is a dedicated utility electric meter connection for the EV charging station, the second case assumes that the EV charging station is part of the total electrical service for a commercial or industrial building complex. The costs associated with EV charging are the electricity used to charge the vehicle, the equipment needed to provide the electricity and charging station maintenance. Both studies use a life cycle cost analysis. The cost analysis shows that these high-power charging stations can significantly add to the facilities monthly electric bill because of utility demand charges and underutilization of the charging facility. A most important result from this work is that an energy management system (EMS) can lend itself to reducing or eliminating the portion of the electric bill associated with charger electrical demand. The detailed results from this project are presented in three reports.
