What Electric Car Charging Apps Do
Electric car charging apps let you find charging stations near you, see whether they are in use, check the charging speed, and pay for the electricity without carrying a credit card to the station. Most apps show real-time availability — whether a charger is free right now or occupied — and let you reserve a spot for a short time while you drive there. Some apps work with only one charging network; others work with multiple networks and show you all of them on a single map.
The main reason to use an app instead of just driving around is that you can see what is available before you leave home or work. If you know a charger is free two blocks away, you can plug in when ready. If every nearby charger is occupied, you can plan a different route or wait and check again in five minutes. Without an app, you might drive to a station and find it full.
Payment through the app means you do not have to stand at the charger fumbling with a credit card reader in the cold or rain. You set up your payment method once in the app, and charging starts when you tap your phone or scan a code at the station. The app tracks your session, shows you how much you are paying per kilowatt-hour, and sends you a receipt.
Key Takeaways
- Charging apps show you real-time availability of nearby stations so you can find an open charger before you drive there.
- Different apps work with different charging networks — some cover only one brand, while others show multiple networks on one map.
- Payment happens through the app, so you do not need to carry a card or use a station's payment terminal.
- Pricing varies by network, location, and time of day, and apps show you the rate before you start charging.
- Some apps let you reserve a charger for 10 to 15 minutes while you drive to it, though the reservation time is limited.
The Major Charging Networks and Their Apps
The largest networks in North America are Tesla Supercharger, Electrify America, EVgo, and ChargePoint. Tesla's app works only for Tesla owners at Tesla Supercharger stations. Electrify America, EVgo, and ChargePoint each have their own apps and work with non-Tesla vehicles. Some networks also let you pay through third-party apps that bundle multiple networks together.
Tesla Supercharger stations are the fastest chargers available — they add 200 miles of range in 20 to 30 minutes — but only Tesla owners can use them through the Tesla app. Non-Tesla owners cannot access these stations through any app. Electrify America and EVgo operate similar fast-charging networks and are available to any electric vehicle owner. ChargePoint focuses on Level 2 chargers, which are slower but cheaper and more common at workplaces, parking lots, and shopping centers.
Aggregator apps like PlugShare, A Better Route Planner, and Chargeway show you chargers from multiple networks on one map. These are useful if you want to compare prices and availability across networks without opening five different apps. However, you still need to set up payment with each individual network, or you can pay through the aggregator app if it offers that feature.
How to read and Set Up a Charging App
read the app from the Apple App Store or Google Play Store by searching for the network name — for example, "Electrify America" or "EVgo." Once installed, create an account using your email address and a password. You will need to add a payment method: a credit card, debit card, or sometimes a bank account linked through a service like Apple Pay or Google Pay.
Some apps ask for your vehicle information during setup — the make, model, and year. This helps the app recommend chargers that work with your car and show you the charging speed you can expect. If you do not enter this information, the app still works, but you may see chargers that are not compatible with your vehicle.
After payment is set up, the app is ready to use. Open it, allow it to access your location, and you will see chargers on a map. The app will show you the charger type (Level 2 or DC fast charging), the price per kilowatt-hour or per minute, and whether it is available. Some apps let you turn on notifications so you get an alert when a charger you are watching becomes free.
Finding and Reserving a Charger
Open the app and look at the map. Each charger appears as a pin or icon, usually color-coded to show availability — green for available, red for in use, and sometimes yellow for offline or broken. Tap on a charger to see details: the exact address, the number of charging ports, the charging speed, the current price, and user reviews.
If a charger is available and you want to use it, you can reserve it through most apps. A reservation typically holds the charger for 10 to 15 minutes while you drive there. If you do not arrive and start charging within that time, the reservation expires and the charger becomes available to others. Reservations prevent you from driving across town only to find the charger is now occupied.
If a charger is occupied, the app usually shows you how much time is left on the current session — for example, "in use, 12 minutes remaining." You can set a reminder to check back, or you can look for a different charger nearby. Some apps let you join a queue, meaning you will get a notification when the charger becomes free, though this feature is not yet common.
Understanding Pricing and Charging Speeds
Charging prices vary by network, location, and time of day. DC fast chargers (which add 200 miles in 20 to 30 minutes) typically cost $0.30 to $0.50 per kilowatt-hour, though prices in some cities are higher. Level 2 chargers (which add 25 to 30 miles per hour of charging) usually cost $0.15 to $0.30 per kilowatt-hour or sometimes a flat fee per hour. Apps show you the price before you start, so you know what you will pay.
Some networks charge by the minute instead of by the kilowatt-hour, especially for fast chargers. This means you pay a set amount per minute of charging time. The app will show you both the per-minute rate and an estimate of what a full charge will cost based on your vehicle's battery size.
Charging speed depends on the charger type and your vehicle. A Tesla can charge faster at a Tesla Supercharger than a Chevrolet Bolt can at an Electrify America station, even if both are DC fast chargers. The app shows you the maximum speed available at each charger, but your actual speed depends on your car's charging capability and the current battery level. Charging slows down as the battery fills up, so the last 20 percent of a charge takes longer than the first 20 percent.
What Happens When You Start Charging
When you arrive at the charger, open the app and tap the "Start Charging" or "Unlock" button. The charger will unlock or set up, and you can plug your car in. The app will show you the charging session in real time: how much power is flowing, how much you have charged so far, and the cost accumulating. You can watch the session from your phone or walk away — the app will send you a notification when charging is complete or if there is a problem.
When you are done, tap "Stop Charging" in the app or unplug your car — most chargers stop automatically when you unplug. The app will show you a receipt with the total energy charged, the total cost, and the time spent. This receipt is saved in your account history, so you can track your charging over time.
If something goes wrong — the charger does not unlock, or it stops charging unexpectedly — the app usually has a help button or a phone number to call the network's support team. Most networks respond within a few minutes during business hours.
Tips for Using Charging Apps Effectively
Plan your route before you leave home. If you are taking a long trip, use the app to find chargers along your route and check their availability. Some apps let you add multiple chargers to a route and see the total charging time needed. This prevents you from running out of power between chargers.
Check the charger type before you go. Not all chargers work with all vehicles. Your car's manual or the app will tell you which types of chargers your vehicle can use. If you have a Tesla, you can use Tesla Superchargers and some third-party networks through adapters, but the app will show you which ones.
Arrive early if possible. Chargers are busier at certain times — typically late afternoon and early evening. If you charge during off-peak hours, you are more likely to find an available charger and may pay less if the network uses time-of-use pricing.
Keep your payment method current. If your credit card expires or is declined, the app may not let you start a charging session. Update your payment information as soon as you get a new card.
Frequently Asked Questions
Can I use one app to charge at different networks?
Aggregator apps like PlugShare show chargers from multiple networks on one map, but you still need to set up payment with each network individually. Some aggregators let you pay through their app instead, but not all networks participate. Check the aggregator app's description to see which networks it covers and how payment works.
What if the app shows a charger as available but it is actually broken?
Apps rely on real-time data from the charging networks, but chargers can fail between updates. If you arrive and the charger does not work, most apps have a "Report Issue" button. Use it to report the problem, and the network will investigate. You can also call the network's support number, which is usually in the app.
Do I have to use an app, or can I pay at the charger?
Most modern chargers require an app or a membership card to start charging. Some older chargers have credit card readers, but these are becoming less common. Check the charger's details in the app to see what payment methods it accepts before you drive there.
Can I charge at home using a charging app?
Charging apps are for public chargers only. If you install a home charger, you plug in directly without an app. Some home chargers have their own apps for scheduling or monitoring, but these are separate from public charging apps.
What if I start charging and then need to leave before it is done?
You can stop charging anytime through the app or by unplugging your car. You will be charged only for the energy you used, not for the full session. The charger will unlock and you can leave. This is useful if you finish your errand faster than expected.
