What public EV charging stations are and where to find them
Public EV charging stations are outlets installed in parking lots, on streets, and at businesses where you can charge your electric vehicle for free or a fee. They are run by cities, private companies, nonprofits, and sometimes the businesses themselves — not by a single national network. The fastest way to find one near you is to use an app or website that maps them in real time.
The three largest mapping services are PlugShare, ChargePoint, and the U.S. Department of Energy's Alternative Fuels Data Center. Each shows you the station location, what type of charger it has, whether it is working right now, and what it costs. Many also let you filter by charger speed or network. Your car's built-in navigation system may also show charging stations, though the information is sometimes outdated.
Charging stations are not evenly spread across the country. Urban areas and highways have far more than rural regions. If you live in or frequently travel through a rural area, you may need to plan longer trips differently or rely on charging at home or work.
Key Takeaways
- Public charging stations are mapped on PlugShare, ChargePoint, and the U.S. Department of Energy's Alternative Fuels Data Center, where you can see real-time availability and pricing.
- Charging speed depends on the charger type: Level 1 takes 24+ hours, Level 2 takes 4 to 10 hours, and DC fast chargers take 20 minutes to an hour.
- Most stations charge by the kilowatt-hour, by the minute, or by a monthly subscription, and prices vary widely by location and network.
- You will need a payment method set up before you arrive — either a credit card, a network membership, or a mobile app account.
- Station downtime is common, so check the app before you drive to one and have a backup location in mind.
The three types of chargers and how long each takes
Charging speed depends on which type of charger the station has. Level 1 chargers plug into a standard household outlet and deliver power very slowly — typically adding 2 to 5 miles of range per hour. You will rarely see these at public stations because they are too slow to be useful away from home.
Level 2 chargers are the most common at public stations. They add 10 to 30 miles of range per hour, so a full charge takes 4 to 10 hours depending on your car's battery size. You will find them in parking lots, at workplaces, and at some retail locations. They cost less to install than faster chargers, so they are cheaper to use.
DC fast chargers are the quickest option, adding 100 to 200 miles of range in 20 to 40 minutes. They are expensive to operate and are usually found along highways, at truck stops, and in urban centers. They cost more per charge than Level 2 but are essential for long road trips. Not all electric vehicles can use DC fast chargers — check your car's manual or the station app before you arrive.
How much public charging costs and what payment methods work
Pricing varies by location, network, and charger type. Some stations are free, but most charge either by the kilowatt-hour (like electricity at home), by the minute, or through a monthly subscription. A Level 2 charge might cost $1 to $3, while a DC fast charge might cost $10 to $30 depending on how much energy you use.
Before you go to a station, check the app to see what payment methods it accepts. Most accept credit cards directly at the charger, but some require you to set up an account with the network first — ChargePoint, Electrify America, and EVgo each have their own apps and membership options. A few stations let you pay through your car's built-in system if your vehicle is compatible.
Some employers, apartment buildings, and shopping centers offer free charging to customers or residents. Check whether your workplace or a place you visit regularly has a charger before paying for a public one.
What to do when you arrive at a station
When you pull up, check the app one more time to confirm the charger is working — stations go offline for maintenance or malfunction frequently, and you do not want to discover this after you have parked. If it is working, open your car's charge port and locate the correct connector type for that charger.
Most public chargers use either a Tesla connector (now called the North American Charging Standard), a CCS connector, or a CHAdeMO connector. Your car comes with one or more adapters, or the charger itself may have multiple connector types built in. Plug in the connector that matches your car's port, then follow the charger's screen or app instructions to start charging.
You will need to authenticate — usually by tapping a card, scanning a QR code, or opening the network's app on your phone. After that, charging begins automatically. Most chargers show how long the charge will take and what it will cost. You can leave your car and come back, or wait nearby.
Planning a long trip with public chargers
Road trips in an electric vehicle require more planning than in a gas car because charging takes longer and stations are less common. Start by mapping your route on PlugShare or A Better Route Planner, which shows you every charger along the way and estimates how long each stop will take.
Plan to stop at DC fast chargers every 150 to 200 miles, depending on your car's range and the weather. Cold temperatures reduce range significantly, so add extra charging stops if you are traveling in winter. Always identify a backup charger within a few miles of your planned stop in case your first choice is broken or occupied.
Charge to 80 percent rather than 100 percent at public stations — charging slows dramatically after 80 percent and wastes your time. If you need more range, it is faster to drive to another charger than to wait for a full charge at one location.
What to do if a charger is broken or busy
Station downtime is common. If you arrive and the charger is not working, the app usually shows a "out of service" or "offline" status, though not always when ready. If you find a broken charger, report it through the app so the network knows to fix it.
If all chargers at a location are in use, you have a few options. Some apps let you reserve a charger for a short time, though this is not standard. You can wait for one to free up, drive to a nearby charger shown on the map, or if you are not in a hurry, charge at a slower Level 2 charger instead. On highways, there are usually multiple charging networks within a few miles of each other.
If you are stranded with low battery and cannot reach a charger, call a towing service — most roadside information plans cover electric vehicles. Some networks also have customer service lines you can call for help locating a working charger.
Membership and subscription options
You do not need a membership to use most public chargers — you can pay per charge with a credit card. However, some networks offer monthly or annual subscriptions that lower the per-charge cost if you use them frequently. ChargePoint, Electrify America, and EVgo each have their own subscription plans, and prices vary by region.
Calculate whether a subscription makes sense for you by adding up how much you would spend on public charging in a month. If you charge mostly at home and only use public chargers occasionally, a subscription probably costs more than pay-as-you-go. If you charge publicly several times a week, a subscription may save you money.
Some subscriptions also give you access to a larger network of chargers or priority reservation at busy times. Read the terms carefully — some subscriptions charge a monthly fee even if you do not use them.
Frequently Asked Questions
Can I charge my electric vehicle at a gas station?
No. Gas stations do not have EV chargers. Some gas stations are adding them, but they are still rare. Use the mapping apps to find actual EV charging stations in your area.
What happens if I leave my car plugged in after charging is done?
Most chargers stop charging automatically when your battery reaches full. Some networks charge an idle fee if you leave your car there too long after charging finishes, so check the app or charger screen for the policy at that location.
Do I need to own an electric vehicle to use a public charger?
Yes. Public EV chargers only work with electric or plug-in hybrid vehicles. If you do not own one yet, you can research charging availability in your area before you buy to make sure public chargers are within reach.
Can I charge my phone or other devices at a charging station?
Some stations have USB ports or outlets for phones, but this is not standard. Do not count on it. Bring your own charger if you need to charge a phone while your car charges.
What should I do if a charger damages my car?
Report the damage to the network when ready through the app or by calling their customer service line. Take photos of the damage and the charger. The network's insurance may cover it, but you will need to file a claim with documentation.
