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 information 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. Data captured on December 31, 2014.
