Executive Summary
Electric vehicle (EV) drivers want a seamless charging experience, but finding a working, available public charger on US interstates is difficult. Across six of the busiest interstates, traversing 40 states, only 34 percent of EV charging stations make real-time data available to PlugShare (a major charger-finding app), creating gaps of up to 1,308 miles with no charger status data.
The solution is simple and cheap—and readily advanced by states. If all fast chargers on highways reported their status in real time so that any software developer could put it in a mapping app, EV drivers could reliably navigate to working, available chargers on a road trip—effectively eliminating their range anxiety. We estimate that making real-time data universal for highway fast chargers would raise the EV share of new vehicle sales by 6.4 percentage points in 2030, expanding the 2030 EV fleet 9.2 percent above baseline projections.
