EV Charging Station Growth Trend

How much has the number of electric vehicle charging stations in the Washington, DC area grown in the last five years? PlugInSites published a count on December 31, 2014. Today, exactly five years later, we take another snapshot and compare the data.

The following EV charging station count is from the U.S. Department of Energy, Alternative Fuels Data Center which keeps track of the number of EV charging stations from data provided by the major charging networks as well as other sources. The figures include public and private stations, DC Fast Chargers as well as Level 2 and Level 1 outlets. The counts below were captured on December 31, 2019. The percentages are the amount of growth of the public charging infrastructure in the five years since 2014.

SAE Combo, CHAdeMO & Tesla Supercharger network comparison. Sept. 12, 2017

Last December when the first Chevy Bolts were being delivered in California, I wondered if it was possible to drive a Bolt EV from coast to coast using SAE Combined Charging Standard (CCS) fast charging stations. I went to the Department of Energy’s Alternative Fuel Data Center (AFDC) website to see the locations of CCS chargers in the US.

I reported that, as of December 15, 2016, there were 884 CCS charging locations listed but they were mostly concentrated on the east and west coasts with some concentrated islands sprinkled around the middle of the country.

While the number of CCS charger sites has grown about 32% in the past nine months, there hasn’t been much progress in distributing the CCS or CHAdeMO fast chargers along the main travel routes to enable long distance travel through the middle of the country.

As of September 12, 2017 there are 357 Tesla Supercharger locations (2,492 outlets) in the US according to the AFDC Station Locator. There are 1,677 CHAdeMO locations (2,045 outlets) and 1,166 SAE Combo locations (1,413 outlets) in the Station Locator. These numbers include both public and private stations. Read More …

SAE Combo, CHAdeMO & Tesla Supercharger network comparison. Maps: US Dept. of Energy, Alternative Fuel Data Center. Dec 15, 2016

With the recent news that the first Chevy Bolts have been delivered to some customers in California, I wondered if it was possible yet to drive coast to coast with a Bolt using a series of SAE Combined Charging Standard (CCS) fast charging stations. To find out the current state of the distribution of CCS chargers in the US, I visited the Department of Energy’s Alternative Fuel Data Center (AFDC) website and this is what I found as of December 15, 2016.

Tesla Superchargers: 327 stations
SAE Combo: 884 stations
CHAdeMO: 1,464 stations (1,956 according to CHAdeMO.com)

Even though there are many more locations for CHAdeMO and SAE Combo stations, the Tesla Supercharger stations are more evenly dispersed, strategically spaced along major Interstate Highways.

The lessons that I learned from attending the recent White House Electric Vehicle Datathon helped me gain insights by looking at the data from both a numerical and geospacial perspective. The Datathon brought stakeholders together to develop best practices for using data to help grow EV adoption and inform the deployment of charging stations.

Looking at the maps, we can only conclude that there needs to be more effort applied to installing SAE Combo and CHAdeMO stations along the Interstates in the middle of the US. The Chevy Bolt and other long-range electric cars cannot fully take advantage of the benefit of 200+ miles of charge until there is a reliable, smartly spaced network of high-speed charging stations. Perhaps the Federal EV Charging Corridors initiative will help bring attention to the needed distribution of DC fast charging infrastructure.

The last time we gathered statistics on the number of plug-in electric vehicles in Maryland, Virginia and Washington, DC was back in September, 2014 published here. The numbers available at the time were somewhat incomplete and an approximation in some cases.

Now, we have some current figures from the Alliance of Automobile Manufacturers to share. These numbers should be much more accurate and show all-electric (BEV) and plug-in hybrid (PHEV) electric vehicles sold since 2011 including those in government and commercial fleets.

We’ve also included statistics for the number of EVs registered in Pennsylvania, Delaware and West Virginia.

Workplace charging has a long way to go. This slide from yesterday’s California Air Resources Board (CARB) meeting shows 1,775 Workplace Level 2 charging stations currently installed in California. (as of September, 2015)

In order to meet the state’s goal of having infrastructure to support 1 million Zero Emission Vehicles (ZEVs) by 2020, there needs to be between 82,000 and 144,000 L2 charging stations according to a report* by the National Renewable Energy Laboratory prepared for the California Energy Commission. *CEC-600-2014-003

The following EV charging station count is from the U.S. Department of Energy, Alternative Fuels Data Center which keeps track of the number of electric vehicle charging stations from data provided by the major charging networks as well as other sources. It may not be a perfect count but it is close enough in my opinion to get a relative sense of the size and growth of the public charging infrastructure. The figures include planned stations, 120v, Level 1 outlets as well as stations marked as private. Charging station count was captured on December 31, 2014.

Maryland: 282 sites, 650 ports
Virginia: 237 sites, 604 ports
Washington, DC: 61 sites, 134 ports
West Virginia: 28 sites, 101 ports
Delaware: 16 sites, 26 ports

Maryland (Sept. 2014)
1,184 all-electric vehicles in Maryland
5,089 total plug-in vehicles including PHEVs and all-electric EVs

• 1,300+ Plug In Prius vehicles
• 1,000+ Chevy Volts
• 450+ Teslas

Virginia (Sept. 2014)
1,968 all-electric vehicles in Virginia (VA doesn’t track PHEVs as separate fuel type)

Washington, DC (May, 2014)
316 all-electric vehicles in Washington, DC (DC counts PHEVs in total hybrid count of 7,959)
