  Overview

Nation-wide Numbers. As of February 2022, there are 116,045 publicly available EVSE (or Electric Vehicle Supply Equipment) ports distributed across 46,985 charging stations in the 51 states of USA, comprising of 22,142 DC Fast Chargers, 92,692 Level 2 Chargers and 1,169 Level 1 Chargers nation-wide.


States with the Most EVSE Ports. California has the highest number of public  EVSE ports at 35,978 ports in its 13,902 charging stations - more than the total number of EVSE ports in the next eight states combined. This accounts for 31% of all EVSE ports in the United States.

  Most DC Fast Chargers. California also has the most number of DC Fast Chargers or DCFCs (6,790 ports - 30.67% of the national total) and Level 2 chargers (28,930 - 31.21% of the national total). New York, Florida and Texas are the other states with at least 5,000 public EVSE ports. New York has 6,901 EVSE ports while Florida has 6,071 ports and Texas with 5,236 ports.deployed. The average number of EVSE ports for a state is around 2,275 ports.

 

Q: What are the main differences between the DC Fast Charger, L1 (Level 1) and L2 (Level 2) Chargers?

 

 

Charging Speeds. A DC Fast Charger can fill an EV battery to 80% within a quick 20 to 40 minutes, and 100% in 60 to 90 minutes, while a Level 2 Charger takes about 8 hours to fully charge up the EV. Level 1 chargers are the slowest form of charging equipment - it can take up to 24 hours or more to deliver a full charge to an empty EV battery.

Charger Locations. These charging speeds affect EV usage patterns and determine where the chargers are usually located. Thus, we can usually find more DCFC installations in public locations and venues where EV drivers make temporarily stops for quick charging, Level 2 chargers at commercial and industrial workplaces where the EV may be parked for up to 8 hours or more and Level 1 chargers at residential areas for overnight or weekend charging.

Cost of Charging. The speed and convenience of charging affects the cost itself. A full Level 1 charge can cost a couple of dollars based on the average cost of electricity at $0.13/kWh. A full charge on a Level 2 installation can cost between $6 to $10 dollars, while the DCFC's convenient and fast charging fetches a premium cost of $10 to $30 dollars, depending on the size of the EV battery.

 


Q: Which are the states with the most EVs?

 

States with the Most EV Registrations. As of June 2021, there are about 1 million registered electric vehicles in the whole of United States. California tops the state with the highest EV registration at 425,300 EVs - a major percentage (41.73%) of the national total..

The other states with at least 50,000 EVs registered are Florida (58,160), Texas (52,190) and Washington (50,520). In contrast, mid-western states such as North and South Dakota and Wyoming have relatively lower EV adoption at less than 500 vehicle registrations.

 


Q: Which states have the best theoretical area coverage in terms of charging stations?

 

  With 247 charging stations on a land area of 61 square miles, the District of Columbia has the best EV coverage with each charging station serving an area of 0.25 square miles or 1 km2. At second, is Massachusetts which has a land area of 7,800 square miles, 2,123 stations and a coverage of 3.67 square miles per charging station. At third best, is Rhode Island which spans 1,033 square miles. With 249 charger stations, each station in Rhode Island theoretically covers an area of 4.15 square miles.

The cost of setting up a charging station of 5-8 ports is quite steep and is estimated to be around $250,000 to $350,000. The ideal scenario of perceived convenience will be a charging station within a 5 to 15 minutes drive,  quite similar to the distribution of gas stations depending on the location and population density. That will imply a radial distance of 3 to 8 miles between charging stations.

 


Q: What are the ratios of EVSE stations and ports to electric vehicles in the states?

 

 

 

Station-to-EV Ratio. The recommendation of the International Energy Administration (IEA)  is one public charging station for every 10 EVs in a region. New Jersey has the worst station-to-EV ratio at one charging station for every 45.81 EVs, followed by Arizona (one station for 33.41 EVs) and Washington (one station for 31.48 EVs).

Within our dataset, only 15 states meet the IEA recommendation, from Nebraska at the passing grade (1 station to 10.11 EVs) to states with exceedingly good station-to-EV ratio - Wyoming (one station to 5.5 EVs) and North Dakota (one station to 3.79 EVs).

 

Port-to-EV Ratio. New Jersey has the highest EVs-to-port ratio with 17.7 EVs to every installed EVSE port.

Hawaii, Washington and Arizona have about one port for every 13 EVs on the roads. California has both the highest EV registration (425,000 EVs) and most number of EVSE ports (35,978 ports), providing one port for 11.8 electric vehicles. For most states, on average, the coverage is around 1 port for 8.8 electric vehicles.

 


Q: Which are the major EV charging network providers in United States?

 

  There are several major players in the U.S. market - ChargePoint being the largest network wih 68,000 charging points including 1,500 Level 3 DC Fast Chargers. Other netowkrs include Electrify America, EVgo with 1,200 DC Fast Chargers, Blink which has 3,275 L2 and L3 charging ports, Tesla Supercharger network and Volta which has 700 stations across 10 states.

  Depending on the specific EVSE port, the supported connectors include SAE J1772 connector, CCS (Combined Charging System by American and European automakers), CHAdeMO (CHArge de MOve byJapanese automakers) and Tesla's proprietary connector.
