Expanding the Availability of Public Charging

Research output: Contribution to conferencePaperpeer-review


Plug-in electric vehicles (PEVs) have exploded into the public consciousness during the past 18 months. As manufacturers roll out the first mass-produced, widely available PEVs, other industry stakeholders are working to create the public charging infrastructure that will provide PEV drivers with the peace of mind to use their vehicles to the fullest potential. Electric vehicle supply equipment (EVSE) manufacturers, vehicle manufacturers, utilities, Clean Cities coalitions, and government officials are working together to reinvent today's vast network of fueling stations by using an energy source that is domestically produced, cleaner, and in abundant supply. Until EVSE becomes as ubiquitous as conventional fueling stations, it is important to provide drivers with an easy way to locate stations. Automakers recognize this fact and are including EVSE locations in their in-vehicle navigation systems. Today, there are nearly 20 EVSE manufacturers and several different data networks linking EVSE stations together. A comprehensive database is required in order to provide the driver with a seamless experience and the ability to locate any available station without worrying about network divisions. The Alternative Fuels and Advanced Vehicles Data Center (AFDC), sponsored by the U.S. Department of Energy's Clean Cities program, hosts a publicly accessible online database of alternative fueling stations, and has been available for over 20 years. The database includes all EPAct defined alternative fuels, but the focus during 2010 and 2011 was to establish relationships with PEV and EVSE stakeholders to develop robust and accurate charging station information. To support EVSE data quality and collection efforts, the National Renewable Energy Laboratory (NREL) established the GeoEVSE Forum. Members of the GeoEVSE Forum include original equipment manufacturers (OEM), EVSE manufacturers, EVSE installers and distributers, utilities and data providers. The members of the GeoEVSE Forum are instrumental in keeping the AFDC database up to date and accurate.
