North America DC fast chargers (CHAdeMO) or SuperChargers - December 2013
The Plugshare.com team is doing a great job listing a large part of charging points, including DC fast chargers - mostly CHAdeMO and Superchargers.
When we add two maps on top of one another - all quick chargers (with some Tesla Superchargers) and Tesla's map with Superchargers, we can see similarities.
First of all, both the CHAdeMO and Tesla infrastructure is growing in basically the same markets and not growing in the same places too. Areas with many DCs must be epicenters of EV sales.
The biggest difference seems to be Tennessee where Nissan has a production plant.
Maybe next year Combo plug chargers will join the map with rollouts in similar locations?
