Analysis and Tools to Set Priorities for EV Charging Stations Locations on WSDOT Corridors

Washington state has 68,000 plug-in electric vehicles registered and estimates it will need one million more on its roads by 2030 to meet its greenhouse gas emissions goals. To meet the anticipated growth in electric vehicle adoption, the state will also need sufficient charging and refueling infrastructure to serve the public. In 2020, the Washington Legislature passed HB1287, which requires WSDOT’s Innovative Partnerships Office to develop and maintain a publicly available mapping and forecasting tool that will provide locations and essential information about charging and refueling infrastructure across Washington state. WSDOT previously supported research that led to the creation of ChargEVal, a simulation tool with a web-based interface that screens Washington’s highway network for adequate coverage of direct current fast charging (DCFC) stations and simulates the impacts of new, user-specified charging station locations on electric vehicle travel and charging demand. This project is building upon that previous work by enhancing the functionality of ChargeEVal, and it will provide technical guidance to WSDOT on a plan to deliver the mapping and forecasting tool required by HB1287.
