Assessment of U.S. electric vehicle charging needs and announced deployments

Existing and announced charging deployments by charging providers, automakers, and retailers cover about 182% of the needed public DC fast chargers and about 62% of the needed public and workplace Level 2 chargers in 2030. [...] Analysis of potential additional chargers from the federal government, states, and utilities, shows that the number of public and workplace chargers in 2030 could increase to more than 244,000 DC fast chargers and 2.2 million Level 2 chargers, which would represent about 225% of the needed DC fast chargers and 84% of needed Level 2 chargers. [...] The mileage and efficiency of the fleet are then multiplied to determine the charging energy demand of the fleet. [...] Level 2 chargers provide 3 to 19 kW of AC power and up to 50 miles per hour of charge, depending on the current rating of the charger and the accepted current rating of the EV. [...] We collected information on the type of charger (Level 2 or DCFC), the number of stations (i.e., sites where charging would be deployed), the number of ports to be installed, when the installation is expected to begin and end, and the costs associated with the project.
