Charging Trends in the United States: a snapshot of Q2 2022

Electric vehicles (EVs) are becoming increasingly popular, and the technology and infrastructure that supports them is evolving rapidly. As of the second calendar quarter of 2022 (Q2 2022), the U.S. Department of Energy's Alternative Fueling Station Locator revealed that the number of electric vehicle supply equipment (EVSE) ports had grown by 4.6%, or 6,165 ports. Public EVSE ports increased by 5.1%, or 5,875 ports, bringing the total number of public ports in the Station Locator to 121,778.
The Mid-Atlantic region saw the largest increase in public charging infrastructure in Q2 (6.7%), though California, which has almost one-third of the country’s public charging infrastructure, still leads the country in the number of public ports. Direct-current (DC) fast EVSE ports had the greatest increase (6.4%) in Q2. However, Level 1 EVSE ports decreased by 12.6%.

DC fast EVSE ports have the highest power output and, therefore, provide the most charge in the least amount of time. Building out the country’s network of public DC fast chargers is critical to supporting EV adoption in the United States. It is estimated that the United States would require 27,500 DC fast and 601,000 Level 2 public and workplace EVSE ports to support a scenario of 15 million EVs on the road by 2030. As of Q2 2022, 89.1% and 17.6% of the required DC fast and Level 2 EVSE ports had been installed.

To meet the Biden administration’s goal of 500,000 EVSE ports by 2030, an average of 12,607 public EVSE port installations will be needed each quarter for the next 8 years, equating to an average quarterly growth rate of 4.8%. Additionally, according to an analysis by McKenzie and Nigro (2021), an additional 252,000 DC fast and 244,000 Level 2 public and workplace EVSE ports would be required by 2030 to support a scenario where 100% of passenger vehicle sales are electric by 2035. As of Q2 2022, the number of DC fast and Level 2 EVSE ports were 9.1% and 31.6%, respectively, of the way toward meeting 2030 infrastructure requirements.

Clearly, the pace of EVSE port installations must significantly increase to meet these goals. It is important to note that the majority (58.2%) of public DC fast EVSE ports in the Station Locator are on the Tesla network, which are only readily accessible to Tesla drivers. When Tesla EVSE ports are removed, this decreases to 37.4% and 15.8%, respectively, of the projected need.
