Who is king of the mountain?
While editing my last post, looking at the maps of DC quick chargers in Japan and in the United States, it made me wonder how the coverage would compare when evaluating the three standards available in the U.S. now. Using the plugshare.com site once again, here is a visual comparison of the CHAdeMO standard, SAE Combo Connector (sometimes referred to as CCS or Combined Charging System), and the Tesla Supercharger network.
CHAdeMO U.S. charge stations – 854 according to CHAdeMO.org
SAE CCS U.S. charge stations – 109 according to plugshare.com
Tesla Supercharger U.S. stations – 89 according to plugshare.com
It is clear that the CHAdeMO standard has a significantly larger installed base at the moment. That said, I just wrote an article (found here) about the addition of roughly 100 SAE CCS stations thanks to BMW and Volkswagen which are not reflected on the map above. These will be part of the ChargePoint network, and ChargePoint just announced that some of these stations will also support the CHAdeMO standard. The additional stations will be primarily up and down the East Coast and West Coast Interstate corridors.
I know that Tesla has plans to continually expand their Supercharger network, and when I visited their site to find out more information, I also found a more complete picture than that shown by plugshare.com.
Tesla Supercharger U.S. stations – 169 according to Tesla
On Tesla’s map the red stations are already installed and the gray stations are planned. Each station offers multiple chargers, which is sometimes the case with both CHAdeMO and SAE CCS. Interestingly plugshare users don’t seem to drive Teslas. Or if they do, they aren’t as interested in updating the plugshare database.
The advantage that the Tesla network provides is a cohesive, manufacturer backed installation that is clearly geared for long distance travel, albeit along narrowly defined routes at the moment. The deployment of the CHAdeMO and SAE CCS networks currently lean more toward regional travel – which makes sense since these vehicles currently offer a shorter range than the Model S. The Supercharger network is not as useful for local or regional travel except perhaps around the Bay Area in California or New York.
It will likely be decades before the U.S. quick charge map is saturated. But considering that none of these maps had any charge stations five years ago, I’d say we’re making measurable progress.
