How to charge an electric car in public

Using a public charger isn’t complicated, but it’s different from charging at home. This guide will walk you through the four main steps to successfully charge your electric car at a public station. Whether you're a new EV owner or just looking to expand your knowledge, this article is designed to help you understand the process and make the most of public charging.

What is Public EV Charging?

Public EV charging refers to any charging station that is accessible to the general public. These stations can be found in places like parking lots, shopping centers, highways, and even on the street. Unlike home chargers, which are typically owned by the driver, public stations are usually managed by third-party providers or businesses. They vary in speed, type, and accessibility, making them a flexible option for EV owners.

How to Use Public Electric Car Charging Stations

1. Locate the Charging Cable

Before you start, find the charging cable. Some stations have built-in cables, while others require you to bring your own. If your car comes with a portable cable, it's usually stored in the trunk. Make sure you know what type of connector your car uses—this can vary by region and charger type.

2. Connect Your Vehicle

Once you’ve located the cable, plug it into your car’s charging port. The location of the port is similar to where a gas cap would be on a traditional vehicle. Some models place the socket under the front badge. If the cable doesn't fit, don’t force it—double-check the compatibility.

3. Authenticate and Start Charging

After connecting, you’ll need to authenticate yourself to start the session. This is often done via an app, RFID card, or contactless payment. Once verified, the charging begins. You’ll see indicators on the charger and your car’s dashboard confirming the process has started.

4. Stop the Session and Disconnect

When your battery is charged to your desired level, end the session using the same method you used to start it. Some stations lock the cable until you disconnect, so check your car’s display for instructions. After unplugging, return the cable to its designated spot if it’s built-in, or store it safely in your trunk.

How Does EV Charging Work?

While the process might seem simple, there are key differences between AC and DC charging. AC (alternating current) is delivered directly from the grid and converted to DC (direct current) inside the car. DC charging, on the other hand, converts the power at the station itself, allowing for faster charging speeds. DC fast chargers can provide up to 350 kW, enabling a full charge in as little as 15 minutes.

AC vs. DC Charging

Understanding the difference between AC and DC is essential when choosing where to charge. Most public stations offer either Level 2 (AC) or DC fast charging. Level 2 is ideal for everyday use, while DC is best for quick top-ups during long trips.

Why Charge at Public Stations?

Even though home charging is convenient, public stations offer flexibility. Many people charge at supermarkets, malls, or work sites while doing errands or running tasks. This “opportunistic” charging helps extend range and reduce the need for long stops. For example, 26% of EV drivers charge at supermarkets, and 31% charge in public or commercial spaces regularly.

How to Find Public Charging Stations

Apps like PlugShare, ChargePoint, and A Better Routeplanner are great tools for finding nearby stations. They show real-time availability, charging speeds, and directions. Google Maps and Apple Maps also include some public chargers, but they may not always provide accurate or up-to-date information.

How to Pay for Public Charging

Payment methods vary. Some stations require a membership or RFID card, while others accept credit cards or mobile payments. It’s important to check whether your preferred method is supported. Some stations may charge higher fees for card payments, so consider setting up an account with a provider for better pricing and tracking.

Charging at public stations offers freedom and flexibility, especially for those who travel frequently or live in areas without home charging options. With the right tools and knowledge, you can easily navigate the world of public EV charging. Whether you're planning a road trip or simply running errands, public stations are a valuable resource for all EV owners.
