The proliferation of DC Fast Chargers (DCFC) will encourage the adoption of electric vehicles, as the FCDC's fast charging capability drastically reduces the pain of waiting time to fully charge an EV from 24 hours to around 90 minutes.
There are, in total, 22,142 DC Fast Chargers (DCFC) in the United States - the state with the most number of DC Fast Chargers is California, which has 6,790 ports or 30.67% of the national total. At a distant second, is Florida with 1,246 DCFCs and Texas at third with 950 DC Fast Chargers. Alaska has the lowest number of DCFCs with only 16 ports.
A DC Fast Charger can fill an EV battery to 80% within a quick 20 to 40 minutes, and 100% in 60 to 90 minutes, compared to the durations of 8 hours (when using a L2 charger) and 24 hours (when using a L1 charger).
A full charge using the DCFC can cost around $10 to $30 dollars, depending on the size of the battery. The cost is expected to be 2-3 times more than the cost of using a L2 charger for the value of speed and convenience.
DCFCs tend to be installed in public locations and venues where EV drivers can make temporarily stops and perform a fast charge.
Example: A ChargePoint Express 250 DC Fast Charger
There are several major players in the U.S. market - ChargePoint being the largest network wih 68,000 charging points including 1,500 Level 3 DC Fast Chargers. Other netowkrs include Electrify America, EVgo with 1,200 DC Fast Chargers, Blink which has 3,275 L2 and L3 charging ports, Tesla Supercharger network and Volta which has 700 stations across 10 states.Depending on the specific EVSE port, the supported connectors include SAE J1772 connector, CCS (Combined Charging System by American and European automakers), CHAdeMO (CHArge de MOve by Japanese automakers) and Tesla's proprietary connector.
