Charging Uncertainty: Real-Time Charging Data and Electric Vehicle Adoption
New NBER paper: Salata and MIT CEEPR researchers find open data from fast chargers would raise EV adoption. Today, only one in three DC fast charging stations adjacent to 6 major Interstates provide their real-time status on PlugShare, a major chargefinding app. Data deserts without real-time data are up to 1,308 miles.
If universal real-time data is accompanied by improved charger uptime and driver confidence in the accuracy of the real-time data, it would effectively eliminate range anxiety, the authors predict. Their modeling estimates that the EV share of new vehicle sales would grow by 8.0 percentage points in 2030, expanding the EV fleet by 13.2%, and reducing 2030 carbon emissions by 22.5 mmt, all versus baseline projections for 2030.
