As the electric vehicle market continues to expand, having enough EV charging stations is essential to enable longer driving ranges and lower wait times at chargers.
Currently, the U.S. has about 140,000 public EV chargers distributed across almost 53,000 charging stations, which are still far outnumbered by the 145,000 gas fueling stations in the country.
This graphic maps out EV charging stations across the U.S. using data from the National Renewable Energy Lab. The map has interactive features when viewed on desktop, showing pricing structures and the connector types when hovering over a charging station, along with filtering options.
Which States Lead in EV Charging Infrastructure?
As seen in the map above, most electric vehicle charging stations in the U.S. are located on the west and east coasts of the nation, while the Midwest strip is fairly barren aside from the state of Colorado.
California has the highest number of EV charging stations at 15,182, making up an impressive 29% of all charging stations in America. In fact, the Golden State has nearly double the chargers of the following three states, New York (3,085), Florida (2,858), and Texas (2,419) combined.
Rank State Number of charging stations Share of U.S. charging stations
1 California 15,182 28.7%
2 New York 3,085 5.8%
3 Florida 2,858 5.4%
4 Texas 2,419 4.6%
5 Massachusetts 2,328 4.4%
6 Washington 1,810 3.4%
7 Colorado 1,718 3.2%
8 Georgia 1,596 3.0%
9 Maryland 1,358 2.6%
10 Pennsylvania 1,260 2.4%
U.S. Total 52,889 100.0%
It’s no surprise the four top states by GDP have the highest number of EV chargers, and California’s significant lead is also unsurprising considering its ambition to completely phase out the sale of new gas vehicles by 2035.
The Best States for EV Charging Speeds and Cost
While having many charging stations distributed across a state is important, two other factors determine charging convenience: cost and charger level availability.
EV charger pricing structures and charger level availability across the nation are a Wild West with no set rules and few clear expectations.
Finding Free Electric Vehicle Chargers Across States
Generous electric vehicle charging locations will offer unlimited free charging or a time cap between 30 minutes and 4 hours of free charging before payment is required. Some EV charging stations located in parking structures simply require a parking fee, while others might have a flat charging fee per session, charge by kWh consumed, or have an hourly rate.
While California leads in terms of the raw amount of free chargers available in the state, it’s actually the second-worst in the top 10 states when it comes to the share of chargers, at only 11% of them free for 30 minutes or more.
Rank State name Number of free charging stations Share of free charging stations in the state
1 California 1,717 11.3%
2 Florida 673 23.6%
3 New York 662 21.5%
4 Texas 606 25.1%
5 Maryland 399 29.4%
6 Georgia 360 22.6%
7 Washington 358 19.8%
8 Pennsylvania 318 25.2%
9 Colorado 273 15.9%
10 Massachusetts 150 6.4%
U.S. Total 10,295 19.5%
Meanwhile, Maryland leads with almost 30% of the chargers in the state that offer a minimum of 30 minutes of free charging. On the other hand, Massachusetts is the stingiest state of the top 10, with only 6% of charging stations (150 total) in the state offering free charging for electric vehicle drivers.
The States with the Best DC Fast Charger Availability
While free EV chargers are great, having access to fast chargers can matter just as much, depending on how much you value your time. Most EV drivers across the U.S. will have access to level 2 chargers, with more than 86% of charging stations in the country having level 2 chargers available.
Although level 2 charging (4-10 hours from empty to full charge) beats the snail’s pace of level 1 charging (40-50 hours from empty to full charge), between busy schedules and many charging stations that are only free for the first 30 minutes, DC fast charger availability is almost a necessity.
Direct current fast chargers can charge an electric vehicle from empty to 80% in 20-60 minutes but are only available at 12% of America’s EV charging stations today.
Rank State Number of stations with DC fast charger available Share of DC fast charger available stations in state Share of free and DC fast charger available stations in state
1 California 1,756 11.6% 0.7%
2 Florida 360 12.6% 1.1%
3 Texas 276 11.4% 1.2%
4 Colorado 243 14.1% 1.1%
5 New York 234 7.6% 0.8%
6 Washington 232 12.8% 1.1%
7 Georgia 228 14.3% 1.4%
8 Maryland 223 16.4% 2.7%
9 Pennsylvania 134 10.6% 1.0%
10 Massachusetts 134 5.8% 0.2%
U.S. Total 6,540 12.4% 0.9%
Just like free stations, Maryland leads the top 10 states in having the highest share of DC fast chargers at 16%. While Massachusetts was the worst state for DC charger availability at 6%, the state of New York was second worst at 8% despite its large number of chargers overall. All other states in the top 10 have DC chargers available in at least one in 10 charging stations.
As for the holy grail of charging stations, with free charging and DC fast charger availability, almost 1% of the country’s charging stations are there. So if you’re hoping for free and DC fast charging, the chances in most states are around one in 100.
The Future of America’s EV Charging Infrastructure
As America works towards Biden’s goal of having half of all new vehicles sold in 2030 be zero-emissions vehicles (battery electric, plug-in hybrid electric, or fuel cell electric), charging infrastructure across the nation is essential in improving accessibility and convenience for drivers.
The Biden administration has given early approval to 35 states’ EV infrastructure plans, granting them access to $900 million in funding as part of the $5 billion National Electric Vehicle Infrastructure (NEVI) Formula Program set to be distributed over the next five years.
Along with this program, a $2.5 billion Discretionary Grant Program aims to increase EV charging access in rural, undeserved, and overburdened communities, along with the Inflation Reduction Act’s $3 billion dedicated to supporting access to EV charging for economically disadvantaged communities.
With more than $10 billion being invested into EV charging infrastructure over the next five years and more than half the sum focused on communities with poor current access, charger availability across America is set to continue improving in the coming years.
