Understanding Electric Vehicle Supply Equipment (EVSE) Networks

Dec. 30, 2014

What are some of the major electric vehicle supply equipment (EVSE) networks, and how can plug-in electric vehicle (PEV) drivers access their stations? What are the costs associated with each network?

Most PEV charging occurs at home, but for those who have a need to charge at a public location, it's important to understand available charging networks. While EVSE networks and charging infrastructure are frequently evolving, a sampling of the major networks currently includes AeroVironment, Blink, ChargePoint, GE WattStation Connect, Greenlots SKY, NRG eVgo, SemaConnect, and Tesla. Each network has a unique model, with the most common approaches being monthly subscriptions, pay-as-you-go (i.e., pay per charge), and free (free to charge and no subscription fee required).

To determine which charging networks have EVSE along your regular routes and close to your frequent destinations, use the Alternative Fuels Data Center (AFDC) Station Locator and the Plan a Route function. Select a station, click "more details," and refer to the "electric charging network" field. Other networks currently represented in the Station Locator include EV Connect, EVSE LLC WebNet, GRIDbot, OpConnect, RechargeAccess, and Shorepower. Please note that many public EVSE are not networked and do not require specific access cards.

EVSE Networks

For detailed information on a range of charging networks, see below. As mentioned above, this is meant to show the diversity among EVSE networks, particularly those represented in the Station Locator, and is not a comprehensive listing.
