Similar to L2 chargers, public fast-charging networks tend to have different pricing structures. The high infrastructure cost makes free fast-charging largely a thing of the past unless in an ad-supported model, but between monthly memberships, billing-per-minute, and ToU rates, many models are being tested. In the NYC metro area at the time of writing, you might see the following approximate pricing for the major players:
BP Pulse: $0.49/kWh + $3/hr or $0.35/kWh
Electrify America: $0.48/kWh or $0.36/kWh + $4 monthly membership
EVgo: $0.23–$0.42/kWh or $0.99/session + $0.43/kWh overnight, $0.56/kWh off-peak, $0.69/kWh on-peak
EvolveNY: $0.35/kWh
Revel: $0.49/kWh
Tesla: $0.28–$0.36/kWh
You need around 30 kWhrs to go 100 miles, so that compares with about 3 gallons for a reasonably efficient ICE. If you have a plug in, charging at home is a must most of the time to save money.
The reality is that, as of right now, few people rely exclusively on public DCFC chargers. Most people do the
majority of their charging at home, and those who do not tend to find L2 chargers elsewhere—either at work, a monthly parking garage, or increasingly at the curbside. This means that for many, the true average cost of charging an EV is closer to the $0.15/kWh that homeowners pay (per 2022 national-average pricing) than it is to the $0.50/kWh common at public fast-chargers.
