As the market for electric vehicles expands, having EV charging stations is important to enable longer driving distances and reduce waiting times at chargers.
Currently, the U.S. has approximately 140,000 public EV chargers spread across approximately 53,000 charging stations, far outnumbering the nation’s 145,000 gas stations.
This graphic maps EV charging stations across the US using data from the National Renewable Energy Laboratory. The map has interactive features that show pricing structures and connection types when viewed on a desktop while switching to a charging station and filter options.
Which countries are leading in charging infrastructure?
As you can see in the map above, most of the electric car charging stations in the US are located on the west and east coasts of the country, while the Midwest is very dry except for the state of Colorado.
California has the most charging stations at 15,182, representing an impressive 29% of all charging stations in America. In fact, the Golden State has nearly double the number of chargers in the following three states: New York (3,085), Florida (2,858) and Texas (2,419).
|Degree||State||Number of charging stations||Share of US charging stations|
It’s no surprise that the top four states by GDP have the most chargers, and California’s significant lead is also not surprising given its ambition to completely end sales of new gas vehicles by 2035.
Best states for EV charging speed and cost
While having plenty of charging stations throughout the state is important, two other factors determine the convenience of charging: value and charger availability level.
EV charger pricing structures and charging tier availability nationwide are a Wild West with no set rules and few clear expectations.
Find free chargers across the state
Electric car charging stations offer unlimited charging or a maximum of 30 minutes to 4 hours of free charging before paying. Some EV charging stations located in parking facilities only charge a parking fee, while others may have a flat fee per session, per kWh consumed, or an hourly rate.
While California leads the state in terms of the raw number of free chargers, it ranks second in the top 10 states when it comes to the share of chargers, with only 11% of them being free for 30 minutes or more.
|Degree||State name||Number of free charging stations||Share of free charging stations in the state|
Meanwhile, Maryland leads the way with nearly 30% of chargers in the state offering at least 30 minutes of free charging. Massachusetts, on the other hand, is the worst state in the top 10, with only 6% of charging stations (out of 150) in the state offering free charging to EV drivers.
States with the best DC Fast Chargers
While free EV chargers are great, having access to fast chargers can be just as important depending on how much you value your time. Most EV drivers across the US have access to a Level 2 charger, and more than 86% of charging stations in the country have Level 2 chargers.
Although level 2 charging (4-10 hours from empty to full) outpaces level 1 charging (40-50 hours from empty to full), between busy schedules and many charging stations that only charge for the first 30 times are free minutes, the presence of a DC charger is almost a necessity.
Direct current chargers can charge an EV from empty to 80% in 20-60 minutes, but are available at only 12% of EV charging stations in America today.
|Degree||State||Number of stations with DC charger available||Share of DC fast charging stations in the state||Proportion of fast charging and DC charging stations available in the state|
As with free stations, Maryland leads the top 10 states with the highest share of DC chargers at 16%. While Massachusetts was the worst state for having DC chargers at 6%, New York State was the worst overall at 8%, despite having more chargers. All other states in the top 10 have DC chargers available at at least one of the top 10 charging stations.
As for the holy grail of charging stations, with free charging and constant availability of chargers, about 1% of charging stations in the country are there. So if you’re hoping for a free top-up and fast DC, the chances are about one in 100 in most states.
The Future of America’s EV Charging Infrastructure
As America works toward Biden’s goal that half of all new cars sold be zero-emission vehicles (battery electric, hybrid electric, or fuel cell) by 2030), charging infrastructure across the country will improve access and convenience for drivers.
The Biden administration has pre-approved 35 states’ EV infrastructure plans, giving them access to $900 million in funding under the National Electric Vehicle Infrastructure (NEVI) formula program to be distributed over the next five years.
Along with this program, the $2.5 billion Voluntary Grant Program to increase access to electricity in rural, underserved and overburdened communities, along with $3 billion from the Inflation Reduction Act to support affordable electricity. It is dedicated to economically poor communities.
With more than $10 billion being spent on charging infrastructure over the next five years, and more than half of that going to communities with poor access, charging access in America will improve in the coming years.
