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.
