Using data from the Alternative Fuels Data Center, the following are new charts that look at three new metrics for DC fast charging networks as of December 31, 2020.

Tesla continues to have the most DCFC locations in the US, though with ChargePoint and EVgo roughly about 150 locations behind and gradually closing the gap.

When it comes to the actual number of ports (connections), however, no one is close to Tesla and its more than 9,500 Superchargers. Electrify America and ChargePoint have roughly one quarter the number of ports as there are Tesla Superchargers. EVgo, which has begun adding Tesla adapters to its charging stations, has 1/7th the number of ports.

And in fact, there are 1,500+ more Tesla Supercharger ports than from ALL other charging networks combined. This obviously has to change to help drive EV adoption in the US, but at the same time, it makes sense with Tesla having accounted for ~80% of BEV sales in the US in 2020.

Lastly, one of my personal favorite metrics looks at the ratio of ports to locations, where no surprise, Tesla dominates with an average of nearly 10 ports per location, more than double Electrify America and roughly 3 to 6 times the other networks. I don’t expect these numbers to change much over the next few years until sales of non-Tesla EVs really take off which leads to an increase in utilization and demand per charging location.

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.
