What an EV charging station map shows you
An EV charging station map is a tool that displays the location of public chargers where you can plug in your electric vehicle. The map shows you where chargers are, what type they are (Level 1, Level 2, or DC fast charging), whether they're available right now, and often what network operates them. Most maps also tell you the charging speed, connector type, and whether you need to pay or if it's free.
The main maps people use are PlugShare, ChargePoint, EVgo, Electrify America, and Tesla's built-in navigation. Some are run by charging networks themselves; others are independent aggregators that pull data from multiple networks. Each one covers different regions more thoroughly, so if one map shows few chargers near you, another might show more.
Key Takeaways
- PlugShare and ChargePoint are the two largest independent maps and together cover most public chargers in North America.
- Maps show real-time availability at many locations, so you can see whether a charger is in use before you drive there.
- Charger type matters: Level 2 chargers take 4 to 10 hours for a full charge, while DC fast chargers take 20 to 45 minutes.
- Many chargers require a membership or app from the network that owns them, so check what payment method each location accepts before you arrive.
The two largest independent maps: PlugShare and ChargePoint
PlugShare is a free app and website that shows chargers from all networks in one place. You can filter by charger type, network, connector type, and whether the charger is currently available. PlugShare also includes user reviews and photos, so you can see what the location actually looks like and whether people have had problems there. The app works offline in some regions, which is useful if you lose signal while driving.
ChargePoint is also free to view, but it's primarily a charging network itself — it owns and operates thousands of chargers. The ChargePoint app shows all chargers (including competitors' chargers), but it's designed to make it straightforward to pay through ChargePoint's own network. ChargePoint chargers are mostly Level 2, concentrated in urban areas and parking lots rather than along highways.
Between PlugShare and ChargePoint, you'll see the vast majority of public chargers in the United States. If you're planning a long trip, checking both maps gives you the clearest picture of what's available along your route.
DC fast charging networks and their own maps
The three largest DC fast charging networks each run their own maps: Electrify America, EVgo, and Tesla Supercharger. These networks focus on highway corridors and major routes because fast chargers are expensive to install and maintain. If you're taking a road trip, you'll likely use one or more of these networks.
Electrify America's map shows chargers along interstates and in cities, with real-time availability and pricing. EVgo's map is similar and covers much of the same ground. Tesla's Supercharger map is built into the Tesla navigation system, but non-Tesla owners can now use Superchargers through the Tesla app — the map shows which locations are open to non-Tesla vehicles.
Each network charges differently: some charge by the minute, others by the kilowatt-hour, and some have monthly memberships. Check the map before you arrive so you know what to expect and whether you need to set up an account first.
How to read charger types and speeds
Level 1 chargers are standard household outlets and charge very slowly — about 3 to 5 miles of range per hour. They're rarely shown on maps because they're not practical for public charging.
Level 2 chargers are the most common public chargers. They deliver 7 to 19 kilowatts and add 25 to 30 miles of range per hour, so a full charge takes 4 to 10 hours depending on your vehicle and the charger's power. You'll find them in parking lots, shopping centers, workplaces, and apartment buildings. Most require you to plug in and then use an app or card to start charging.
DC fast chargers deliver 50 to 350 kilowatts and add 150 to 200 miles of range in 20 to 45 minutes. They're expensive to use but essential for road trips. The map will tell you the charger's kilowatt rating — higher kilowatts mean faster charging, but your vehicle's onboard charger limits how fast it can actually accept power.
Understanding connector types and compatibility
The connector type matters because not all chargers fit all vehicles. The three main types in North America are Tesla connector (also called NACS), CCS (Combined Charging System), and CHAdeMO. Most maps show which connectors are available at each location.
Tesla vehicles use the Tesla connector, but newer Teslas and many other brands are moving to NACS as the standard. CCS is the most common connector for non-Tesla vehicles. CHAdeMO is older and becoming less common, though some Nissan Leaf owners still use it. Before you buy a vehicle or rely on a particular charger, check the map to see what connectors are available in your area and along routes you plan to drive.
Some chargers have multiple connectors at the same location, so you may have options. The map will show you all available connectors, so you can plan accordingly.
Using maps to plan a road trip
To plan a long drive, start by entering your starting point and destination into the map. Most maps let you see all chargers along the route and filter by type. For a road trip, you'll want to focus on DC fast chargers because they're the only practical option for highway driving — Level 2 chargers take too long for a trip where you're trying to make progress.
Check the real-time availability feature if the map offers it. Some chargers are broken or in use, and you don't want to drive 50 miles expecting to charge and find the location offline. If a charger shows as unavailable, look for an alternative nearby. Most maps let you see the next charger on your route, so you can plan stops in advance.
Write down the network names and any membership or app requirements before you leave. Some networks require you to set up an account and add a payment method before you can charge. Doing this at home is much easier than trying to do it on the road with spotty signal.
Free chargers versus paid chargers
Some chargers are free, but most charge a fee. Free chargers are usually Level 2 and found at workplaces, shopping centers, or municipal parking lots. They're convenient if you're parked for several hours anyway, but you can't rely on them for road trips.
Paid chargers charge by the minute, by the kilowatt-hour, or through a monthly subscription. DC fast chargers are almost always paid and cost between $10 and $35 for a full charge depending on the network and your vehicle's size. Level 2 chargers usually cost $1 to $3 per hour. The map will show you the pricing at each location, though some networks don't display prices until you open their app.
If you charge at home regularly, you may not need to use public chargers often. But if you live in an apartment without a charger or take frequent road trips, understanding the cost structure helps you budget and choose the most economical network for your needs.
Frequently Asked Questions
Can I see real-time availability on all maps?
Most large maps show real-time availability for at least some chargers, but coverage varies. PlugShare and ChargePoint show availability at many locations, but smaller networks may not. If the map doesn't show real-time data, you can call the location or check the network's app directly before you drive there.
What should I do if I arrive at a charger and it's broken?
Report it through the map app or the network's app so other drivers know. Most networks have a customer service number you can call if you're stranded. Keep the charger location and network name handy so you can tell them exactly where you are. Have a backup charger location in mind before you start charging.
Do I need to read multiple apps to use different chargers?
You don't have to, but many people do. PlugShare and ChargePoint let you pay through their apps at many locations, but some networks (like Tesla Supercharger and Electrify America) work best through their own apps. Check which networks operate chargers near you and along your regular routes, then read the apps you'll use most often.
How do I know if a charger will work with my vehicle?
Check your vehicle's manual or the manufacturer's website to see what connector types it accepts. Then filter the map by that connector type. If you're not sure, call the charger location or the network's customer service before you drive there — they can tell you whether your vehicle will work.
Are charging maps updated frequently?
Maps are updated regularly, but new chargers may take weeks to appear on all maps. If you see a charger on one map but not another, it may be very new. Chargers that are broken or permanently closed may stay on maps for a while, so always check real-time availability or call ahead if you're relying on a specific location.
