Your First Time Using a Public EV Charger: What to Expect

Which Connector Fits Your Car?

Before you drive to a public charger, find out which connector your car uses. This is the single most important thing to know. The connector is the plug that connects the charging cable to your car's charge port. Different regions and different vehicles use different types, and they are not interchangeable.

Here are the main ones you will encounter. CCS (Combined Charging System) is the most common DC fast charging connector worldwide. It is standard on nearly all new EVs sold in Europe, Australia, and the US (except Tesla). CCS has a round top section for AC charging and two additional pins below for DC fast charging. CHAdeMO is an older DC fast charging standard, still found on some Nissan Leaf and Mitsubishi Outlander PHEV models. It is being phased out in most markets but is still common in Japan. NACS (North American Charging Standard) is Tesla's connector. It is smaller and lighter than CCS. Starting in 2025, most major US automakers are adopting NACS for new models, and Tesla Superchargers are opening to non-Tesla vehicles in the US. Type 2 is the standard AC connector in Europe and Australia. It is used for slower charging (up to 22 kW AC) and is the top portion of the CCS connector.

Check your car's manual, the sticker near the charge port, or the manufacturer's website if you are not sure. You cannot plug in the wrong connector by accident. They are all physically different shapes.

How Do You Find a Public Charger?

Most EVs have a built-in charger map in the navigation system. This is usually the easiest way to find nearby stations. Your car knows which connectors it supports and can filter results accordingly.

You can also use third-party apps. In the US, the ChargePoint and Electrify America apps show their own networks, while PlugShare and A Better Route Planner cover multiple networks. In Europe, networks like Ionity, Shell Recharge, and Fastned each have their own apps, but apps like Chargemap and ABRP work across networks. In Australia, Chargefox and NRMA have apps for their networks, and PlugShare covers the broader landscape. Apple Maps and Google Maps also show public chargers in most countries now.

Before you drive to a charger, check a few things. Does it have the right connector for your car? Is it currently available or occupied? Is it a fast charger (DC) or a slow charger (AC)? Some apps show real-time availability, which can save you a wasted trip.

How Do You Actually Start Charging?

The process varies slightly by network and country, but the basic steps are always the same. Park your car so the charge port is close to the charger cable. Open your charge port (usually a button on the dash, key fob, or a push on the port cover itself). Pick up the cable with the correct connector. Plug it into your car firmly until it clicks. Then authenticate to start the session.

Authentication is where it gets confusing for first-timers. Some chargers require you to tap an RFID card. Some require you to start the session from an app on your phone. Some have a screen where you tap a contactless credit card or debit card. And some, like Tesla Superchargers for Tesla vehicles, start automatically when you plug in.

If the charger does not start, do not panic. Check that the connector is fully seated in your car's port. Make sure your car is in Park. Try authenticating again. If it still does not work, try the next stall. Charger reliability varies, and a failed start does not mean you did something wrong.

The order matters. Some networks want you to authenticate first, then plug in. Others want you to plug in first, then authenticate. If you are not sure, look for instructions on the charger's screen or printed on the unit.

What Happens While You Charge?

Once charging starts, your car and the charger communicate constantly. The charger screen (or your app) will show the current charging speed in kW, how much energy has been delivered in kWh, and an estimated time to reach your target level.

Do not be surprised if the charging speed fluctuates. On a DC fast charger, your car might start at 150 kW and gradually slow down as the battery fills up. This is normal. The battery management system controls the speed to protect battery health. Cold weather, a hot battery, or a high state of charge all reduce the speed your car will accept.

You do not need to stay at the charger. Many drivers grab a coffee, stretch their legs, or use the restroom. Just keep an eye on your app or the charger's notification so you can move your car when it is done. Some networks charge idle fees if you leave your car plugged in after charging completes.

How Do You Pay?

Payment methods vary by network and country. The most common options are a charging network app with a linked payment card, an RFID card from the network or a roaming provider, or contactless payment (tap your credit card or phone directly on the charger).

In Europe, many drivers use roaming cards or apps that work across multiple networks, so you do not need a separate account for every provider. Shell Recharge, Plugsurfing, and Maingau are examples of roaming providers. In the US, each network typically has its own app and account. ChargePoint, Electrify America, EVgo, and Tesla each require their own. In Australia, Chargefox works across most of the fast charging network.

Pricing structures also differ. Some chargers bill per kWh (the amount of energy delivered). Some bill per minute. Some have a flat session fee. And some combine these. Check the pricing before you start, either on the charger screen, in the app, or on the network's website. There should be no surprises if you look first.

When Should You Stop Charging?

At a DC fast charger, 80% is usually the sweet spot. After about 80%, the charging speed drops significantly. The last 20% can take as long as the first 60%. If you are on a road trip, it is almost always faster to charge to 80%, drive to the next station, and charge again, rather than waiting for 100%.

At a slower AC charger (at a hotel, workplace, or shopping center), charging to 100% is perfectly fine. The slower charging speed means the battery management system is not under the same stress. For daily driving, most manufacturers recommend keeping your battery between 20% and 80% as a general guideline. But if you need the full range, charging to 100% occasionally will not harm your battery.

What Are the Most Common First-Timer Mistakes?

Arriving without knowing your connector type. This is the number one avoidable mistake. If you show up at a charger that only has CHAdeMO and your car needs CCS, you cannot charge. Know your connector before you leave home.

Not having the right app installed. Standing in a parking lot, downloading an app, creating an account, and entering your payment details while your battery is low is stressful. Set up accounts with your local charging networks before your first public charge.

Confusing AC and DC chargers. A 7 kW AC charger will take hours, not minutes. If you are expecting a quick top-up, make sure you are going to a DC fast charger (50 kW or higher). The difference between 7 kW and 150 kW is the difference between all afternoon and half an hour.

Assuming it works like a gas station. There is no attendant. The charger might need you to use an app before the cable will unlock. The cable might be heavy and awkward. The payment might not go through on the first try. Give yourself a few extra minutes the first time. It gets easier fast.
