DCFC Locations, Ports and Ratio: Tesla vs. Other Networks

At the end of August, the Tesla Supercharger network reached 11,125 DC fast charger ports across the US, accounting for 57.1% of all DCFC ports. With 1,118 locations, however, the Supercharger network accounted for only 20.1% of the total DCFC locations. 

But with an average of nearly 10 chargers/ports per location, Tesla’s Supercharger network outpaces the rest of the DCFC networks 5 to 1. The average of only 2 DC fast chargers per location at the non-Tesla networks is becoming problematic as EV sales increase and reports of many chargers being unavailable also rise. 

It is one thing for an EV driver to arrive at a location with 1 of 12 chargers not working, but yet another if 1 out of 2 chargers at a location are down and the working one is being used. Reliability is one of the biggest weaknesses of the charging networks, an issue I will dive into in the future.



Average Range and Battery Size of PHEVs Currently Available in the US

With 32 PHEVs currently available in the US (as of September 21, 2021), they come in a wide variety of types, price, EPA range, and battery size. In the chart below we’ve analyzed the 32 PHEVs across 6 metrics. The mean (commonly referred to as the average) range is 24.7 miles and mean battery size is 13.5 kWh. When looking at the median, however, range drops to 21 miles and battery size down to 12.5 kWh.
