Public EV Chargers

When it comes to refueling a car, drivers of gas- and diesel-powered vehicles have it easy. They roll up to any one of about 100,000-plus gas stations in the U.S., pump in liquid fuel in a matter of minutes, and pay either in cash or with a credit card. Unfortunately, it’s a little more complicated with public charging for electric vehicles—although remember that almost all EV charging takes place at home, which usually requires about 30 seconds to plug in each night.

For EV drivers who want to regularly charge in public, it’s important to know about the handful of charging networks offering access to electric fuel on the go. Each network works a little differently. It’s a good idea for EV owners to have a basic understanding of how they compare with one another. That’s why we put together this basic guide on EV charging networks. It’s a work-in-progress, and your input and feedback are encouraged.

Cost Considerations

The three primary approaches are: (1) pay-as-you-go, (2) monthly subscriptions, and (3) free. If given the opportunity, it makes sense to grab a free charge, even for a relatively short period of time. But the pay models, depending on the cost for a charge, need to be studied to determine which network makes the most sense for you—if it’s best to collect a wallet-full of membership cards or if proper planning will allow you to avoid public charging unless you’re running very low on charge.

There are a few gotchas. Keep in mind that the amount of range you add per hour depends on the power capabilities of your car’s onboard charger. As Marc Geller, a director at Plug In America, an EV advocacy organization, told us: “If the car comes with a smaller charger, the cost is relatively higher than if you have a faster charger. It’s a weird fact.” Other oddities include credit card transactions and costs associated with leaving a car plugged in even if the battery is fully charged and the electrons have stopped flowing. Some of the networks have an unlimited charging plan to avoid these pitfalls.

As of March 2018, the majority of public chargers are still available for free (although not every system makes it absolutely clear how much EV drivers are paying to charge). There are nearly 47,000 free, public locations to charge an EV, while there are not quite 40,000 paid, public locations. (These numbers don't count the nearly 2,000 paid locations that are not fully public, such as spots where only employees of a company can charge.)

High-Level Recommendations

  • First, think about your regular routes and favorite destinations. Then use PlugShare or another station-finding tool to see which charging networks are along the way. Be prepared to use any of them.
  • ChargePoint is the biggest charging network, so it’s a must for nearly all EV drivers.
  • If you live in Pacific Northwest, get a key fob from Webasto (formerly Aerovironment) for its network.
  • Sun Country, a smaller player, primarily serves Canada.
  • Greenlots mostly supplies Quick Chargers rather than Level 2, 240-volt chargers.
  • On the east coast, SemaConnect is the best backup to ChargePoint.
  • Use PlugShare to find these stations.

One last caveat: The terminology of ''station” can be confusing and misleading. Some services call each individual charger a station when the term station usually refers to a single public site with the capability to charge more than one car at a time.

List of Top EV Charging Networks


Blink Charger

Background: The assets of Blink Network were purchased by CarCharging Group in October 2013. Ecotality had received a $114.8 million federal stimulus grant to oversee The EV Project. The goal of The EV Project is to deploy 8,300 private and public chargers. There have been several reported problems associated with Blink chargers, and the Blink Network, such as insufficient customer support, and incompatibility of the equipment with certain vehicles. The name of the company managing the Blink Network was CarCharging Group, but the company was renamed as "Blink Charging."

Approximate Number of Sites:1,680

Coverage: Blink Network chargers are located in approximately 25 states, with the largest concentration in California, Arizona, Oregon, Texas, Tennessee and Washington.

Access: Start by registering a credit card with a Blink account. There are no required annual or monthly membership fees, or minimum credit card balance. Members who register will receive an “InCard” and can initiate a charge using the card. Guests can initiate a charge with Blink’s mobile application.

Cost Per Charge: In the states that permit kilowatt-hour pricing, fees for Level 2 EV charging stations owned by Blink and operated on the Blink Network range from $0.39 to $0.79 per kWh, depending on the state and individual’s membership status. Blink is a proponent of kWh pricing because it is usage-based and EV drivers pay fees based on the actual amount of power consumed during the charging session rather than the amount of time that the car is plugged into the station. Fees for DCFC chargers owned by Blink and operated on the Blink Network in kWh eligible state range from $0.49 to $0.69 per kWh, depending on the state and individual’s membership status.

These states currently permit fees by the kilowatt-hour: California, Colorado, Florida, Hawaii, Illinois, Maryland, Minnesota, New York, Oregon, Pennsylvania, Utah, Virginia, Washington, and Massachusetts, as well as the District of Columbia.

In states where pricing by kWh is not permitted, time-based charging fees for Level 2 charging stations owned by Blink and operated on the Blink Network range from $0.04 to $0.06 per minute, depending on membership status. Time-based charging fees are rounded up to the nearest 30-second interval. Fees for DCFC chargers owned by Blink and operated on the Blink Network in non-kWh eligible states will range from $6.99 - $9.99 per session, depending on membership status.

Tesla Supercharger

Background: Tesla Motors offers its own propietary charging network to serve the refueling needs of owners of its Model S, Model X, and Model 3 vehicles. Tesla Superchargers are standalone sites, while the company has also established sites, called "destinations," that are managed in partnerships with hospitatlity, retail,
workplace, and multifamily entities. Tesla supercharging stations charge with up to 145 kW of power distributed between two cars with a maximum of 120 kW per car. They take about 20 minutes to charge to 50 percent, 40 minutes to charge to 80 percent, and 75 minutes to 100 percent on the original 85 kwh Model S.

Approximate Number of Sites: As of March 2018, there are about 492 available Superchargers and more than 3,000 Tesla Destinations.

Cost Per Charge: As of January 1, 2017, anyone who orders a Tesla will get just 400 kWh of free Supercharging credits per year, good for about 1,000 miles of driving. Tesla has not revealed how much it will cost after that limit but says a "small fee" will be cheaper than buying gas. Owners who ordered their car in 2016 or earlier will still charge for free, for life. That excludes owners of the Tesla Model 3.


Technical Support: Available toll-free at 877-79-TESLA
