Abstract

Oregon has more DC Fast Chargers (DCFC) for electric vehicles per capita than any other US region. This network has played a major role in making Oregon one of the strongest markets for electric vehicle sales in the US, despite the lack of a state purchase incentive. This paper summarizes Oregon’s experience with fast charging, evaluates the impact of this network, proposes new ways of defining network “success,” and makes recommendations for cost effectively expanding the network. These findings and recommendations should help inform other regions that are just beginning to build out their fast charging networks.

Highlights

  • Interstate 5 is the major freeway connection running over 2,000 km from the U.S border with Canada, through Washington, Oregon, and California, to the U.S border with Mexico

  • The West Coast Green Highway” (WCEH) today is an extensive network of DC fast charging stations located every 40 to 80 km along Interstate 5 and other major roadways in the Pacific Northwest.[2]

  • Another measure of success is whether the DC Fast Chargers (DCFC) network provides a foundation of consumer confidence that drives increasing sales of electric vehicles and an increasing number of electric vehicle miles travelled (e-VMT.) Oregon has committed to accelerate sales of electric vehicles by opting in to the Zero Emission Vehicle (ZEV) mandate, and has joined the International ZEV Alliance, committing to a goal that all new cars sold in Oregon will be electric by 2050

Summary

Fast Charging in Oregon

Interstate 5 is the major freeway connection running over 2,000 km from the U.S border with Canada, through Washington, Oregon, and California, to the U.S border with Mexico. Electric Avenue solicited charging equipment from several different companies and placed it side by side to evaluate its technical characteristics, its reliability in use, and the consumer experience of charging This deployment yielded many lessons about technology and the user experience, which have been summarized elsewhere.[7]. As a result of these coordinated efforts, Oregon has the most robust state-wide network of DC Fast Chargers in the nation, with about 120 stations in operation and more being added monthly, to serve a population of 4 million and a fleet of over 9,000 electric cars. This network covers most of the region’s major transportation corridors

Defining “Success”
Next Steps for Oregon
Densify the network in metro areas
Add SAE combo to key corridors
Ensure that key destinations outside metro areas are within reach
Lessons Learned and Recommendations
Fast Charging Corridors are Great Marketing
However
Fast Chargers Must be Completely Reliable
Install Chargers in “Pods”
Deal With Demand Charges
Make Chargers Dual Standard
Cooperate and Co-locate
Ensure an Excellent Driver Experience
Develop Creative Solutions for Remote Locations
