Electric mobility is no longer a futuristic idea. Today, electric vehicles (EVs) are rapidly becoming the standard choice for drivers around the world. With the global EV fleet expected to exceed 20 million this year, it's clear that the shift to electric is accelerating.

Switching to electric driving may seem complex at first, but it’s actually quite straightforward once you understand the basics. To help you get started, we’ve compiled the 7 most common questions about electric car charging and provided clear answers.

1. How does electric charging work?
2. What powers electric car charging stations?
3. How long does it take to charge an electric car?
4. What does it cost to charge an electric car?
5. How often do you have to charge an electric car?
6. Where can I charge my electric car?
7. How much maintenance does an EV charger need?

1. How does electric car charging work?

Charging an electric vehicle is simpler than it might seem. Most EVs come with a standard charging cable and plug compatible with your local power outlets. You can plug your car into a regular home socket or use a dedicated charging station.

How do EV charging stations work?

Public charging stations usually require identification via an app, card, or contactless payment. Once connected, the process is straightforward: plug in the cable, start the session, and wait for your car to charge. Some newer systems even support automatic recognition through Plug & Charge technology.

How do you pay for electric car charging?

At home, your EV’s electricity usage will be added to your regular bill. Public charging stations often offer flexible payment options, including pre-paid cards, subscriptions, or mobile apps.

2. What powers electric car charging stations?

There are two main types of EV chargers: AC and DC. AC chargers are slower but more common, while DC chargers provide faster charging by converting electricity before it reaches the car.

AC vs DC electricity

Most EVs store energy as DC, so AC must be converted. Level 1 and 2 chargers convert AC on board, while DC fast chargers do it at the station, allowing for much quicker charges.

3. How long does it take to charge a car battery?

Charging time depends on the battery size, charger type, and current charge level. For example, a Tesla Model S can fully charge in about 7 hours using a Level 2 charger, but only 30 minutes with a DC fast charger.

EV charger types

Level 1 is slow and ideal for home use. Level 2 is faster and commonly found in public spaces. Level 3 (DC) is the fastest but not suitable for residential areas due to high power demands.

4. What does it cost to charge an electric car?

Cost varies by location and charger type. On average, a full charge at home costs around €20–€30, depending on your region and electricity rates. Public fast chargers tend to be more expensive.

5. How often do you have to charge an electric car?

It depends on your driving habits and the car’s range. Most EVs can last several days between charges, especially if you keep your battery between 20% and 80%.

6. Where can I charge my electric car?

You can charge at home, at work, or at public charging stations located in parking lots, supermarkets, gas stations, and more. Home charging is the most popular option, with many drivers choosing to charge overnight.

7. How much maintenance does an EV charger need?

Home EV chargers require minimal maintenance—just occasional checks for damage. Public stations need more regular upkeep, including software updates and hardware inspections. Many manufacturers offer service plans for convenience.

Switching to electric is a smart move, offering flexibility, lower running costs, and a cleaner environment. If you're new to EVs, don’t worry—charging is easier than you think. For more details, check out our complete guide to EV charging.
