EV Charging

As “filling” stations for EVs are not as universal or widespread as petroleum stations, EV owners have created their own community supported by a variety of smart phone apps and online tools. EV users share information on EV charging station availability, parking and fueling costs, charging network, and even report maintenance needs.

Charging Station Levels

  • Level 1 provides 2 – 5 miles for 1 hour of charging
  • Level 2 provides 10 – 20 miles for 1 hour of charging
  • Level 3 DC fast charger provides 60 – 80 miles for 1 hour of charging

Charging Infrastructure Terminology

The charging infrastructure industry has aligned with a common standard called the Open Charge Point Interface (OCPI) protocol with this hierarchy for charging stations: location, electric vehicle supply equipment (EVSE) port, and connector. The Alternative Fuels Data Center and the Station Locator use the following charging infrastructure definitions:

Station Location: A station location is a site with one or more EVSE ports at the same address. Examples include a parking garage or a mall parking lot.

EVSE Port: An EVSE port provides power to charge only one vehicle at a time even though it may have multiple connectors. The unit that houses EVSE ports is sometimes called a charging post, which can have one or more EVSE ports.

Connector: A connector is what is plugged into a vehicle to charge it. Multiple connectors and connector types (such as CHAdeMO and CCS) can be available on one EVSE port, but only one vehicle will charge at a time. Connectors are sometimes called plugs.
