The electric vehicle is here to stay. As EV sales grow year-over-year in the US and the rest of the world, charging infrastructure is growing with it. In the US specifically, certain states are far better equipped than others to support the rising number of EV drivers on their roads. Below is a breakdown of some of the best states for EV charging along with some of the… less than best.
Anyone who has visited the US can attest that it’s a rather large country with 50+ cultural and economic identities. United federally, but still independent locally, these states are responsible for much of their own governing and decisions as it pertains to that specific state. This includes charging infrastructure.
As the number of electric vehicles on roads grows, many states are not equipped with the charging network this zero-emission shift requires. On the flip side, others are much better off to start. Factors such as size, geography, weather conditions, and even culture have all had their affect on how quickly or slowly electrification has been adapted.
As you will see below, there is more to this equation than simply how many EVs are on roads in a given state, versus how many chargers are available (although we do share that data as well). Let’s break it down.
To determine which states are truly the best for EV charging, Zutobi released a detailed report using data from US government sites. We then took this same strategy and updated it using the most up-to-date stats.
For example, the number of public charging outlets in each state is sourced from the US Department of Energy''s (DOE)Alternative Fuel Station Counts by Statereport. This report was last updated on November 8, 2021. This number was based on the total number of charging outlets, regardless of charging type (level 1, 2, DC fast charge).
To best determine the number of EVs charging in each state, the DOE''sElectric Vehicle Registrations by Statewas used. The data refers to the number of registered electric vehicles as of June 2021.
To calculate the total number of vehicles registered in each state, we sourced data from the US Department ofTransportation''s State Motor-Vehicle Registrations 2019. The data used was the number of private and commercially owned automobiles.
Lastly, the number of EVs per mile in each state was calculated using US road data from 2019, gathered by the Institute for Policy & Social Research at University of Kansas. The total length of road (in miles) was divided by the number of EV charger outlets in each state to determine how far apart chargers theoretically are on average.
This make sense, given all three states’ geographical size and large populations in comparison to other states. Additionally, California and Florida are also the top two states with both the most registered EVs and total vehicles overall. Texas comes in at third.
Conversely, Alaska has the fewest total number of EV charging outlets followed by the Dakotas. We will give Alaska a pass since nearly 50% of the state remains uninhabited, but North and South Dakota have some catching up to do. Wyoming and Montana do, too.
If it wasn’t already clear by now, California is leading the pack in nearly every category. But as you will see below, that doesn’t necessarily make The Golden State the best to charge your EV in the future.
New Jersey tops our list by nearly four more EVs per charger compared to second place. The Garden State has an impressive 30,420 registered EVs, chasing its neighbor New York which only leads by 2,000 more. Despite its robust EV numbers, the lack of charging is apparent – just 1,638 chargers averaging over 18 EVs per charger in the state. Luckily, New Jersey is in a great location in the Northeast. Try Pennsylvania or Delaware as backups.
If you’re one of the 28k+ EV drivers in The Grand Canyon State, you may have already noticed some infrastructural issues when trying to charge. The number of registered EVs in the state puts AZ in the top half of its US class, but with less than 2,000 charging ports available, you may find yourself waiting to get a charge more often than in other states. Mathematically, there are more than 14 EVs in the state per charger..
The scarcity of EV chargers, at least in comparison to the number of EVs on the islands makes sense, given the Aloha State’s geographical limitations. Despite being 2,000 miles from the contiguous United States, Hawaii still has more registered EVs (10,670) than several other states combined. However, with only 743 chargers available, Hawaii residents also (theoretically) face over 14 EVs per charger. Not to mention that those 743 chargers exist across multiple islands.
Using the same method, there are several states have a much better ratio of chargers to EVs. That being said, many of the lower ratios are the result of both low EV registrations and limited chargers.
To keep things theoretical but expose how much charging infrastructure is lacking in most states, we broke things down by mileage. We accomplished this by comparing the number of charging outlets available against how many miles of road exist in each state.
From here you can see the theoretical distance between each EV charger, if you were to distribute them out equidistant across each state’s roads. Many distances are manageable, but other states might require over 600 miles of range just to get you to your next charge.
Alright, it’s technically not a state, but it probably should be. DC is the home to the federal government and so much more. This includes 684 public charging ports across the district, one every 2.2 miles. The data may be slightly skewed since DC only has about 1,500 miles of roads. Even so, DC has over 2,300 registered EVs – that’s over 10x more than North Dakota.
The largest state on the left coast comes in at second on our list with an impressive ration given its sheer numbers. California remains years ahead of all states in current EV infrastructure, having 180x more registered vehicles and 50x more charging outlets than DC. Its mileage ratio is simply more evidence of such as well. While The Golden State contains over 175,000 miles of roadways, one of its 34k+ EV chargers is theoretically available every 5.05 miles.
Entering the top three again is Hawaii. With such limited space (you know, because of mountains and volcanoes), Hawaii only offers about 4,500 miles of roads. Given its 743 chargers outlined above, however, EV drivers should theoretically find a charging port every 6.06 miles.
