As electric vehicles (EVs) become more popular in the UK, knowing how to use a car charger is essential for every driver. Whether you’re charging at home, at work, or on the public network, understanding the basics can help you stay safe, extend your battery life, and avoid unnecessary costs.
In this guide, we’ll explain everything you need to know about using a car charger — from plugging in correctly to choosing the right type of charging point.
What Is a Car Charger?
A car charger (also known as an EV charger or electric car charger) is a device that supplies electricity to the battery of an electric or plug-in hybrid vehicle. Car chargers come in three main types:
- Slow chargers – usually a 3-pin plug or basic home unit
- Fast chargers – typical 7kW–22kW home or workplace chargers
- Rapid chargers – high-power 50kW+ chargers found at service stations
Understanding the differences helps you choose the charger that best suits your journey.
How to Check Compatible Car Chargers for My Car
Using Total Car Check’s free car check, you can also access valuable car charger information at no cost. When you enter a vehicle’s registration, our system retrieves key data for electric and plug-in hybrid cars, including charging type, charge costs, connector compatibility, battery capacity, on-board charger rating and estimated charging times. This helps you understand exactly which chargers the vehicle supports — at home, at public fast chargers and at rapid charging stations — before you buy. It’s a simple, reliable way to verify EV charging details in seconds and avoid purchasing a car with unexpected charging limitations.
How to Use a Car Charger at Home
Home charging is the easiest and most common way to charge an electric car. Here’s how to do it safely:
1. Park close to the charger
Ensure the charging cable can reach your car’s charging port without tension.
2. Unlock and open your car’s charging port
Most cars use a button on the dashboard, key fob, or touchscreen.
3. Plug the connector into your vehicle
Push firmly until it clicks into place.
4. Start the charging session
Depending on your charger:
- It may start automatically
- Or you may use an app (e.g. Pod Point, Wallbox, Ohme)
5. Check charging status
Look for:
- Car dashboard indicator
- Charger light
- App notification
6. End charging safely
Stop charging in the car or app, unlock the cable, and unplug.
Tip: Charge overnight on off-peak electricity tariffs to reduce cost.
How to Use a Public Car Charger
Public charging points can be slightly different depending on the provider, but the process is similar.
1. Choose the right charger
Most public chargers are:
- Fast chargers in car parks, supermarkets, retail parks
- Rapid chargers at motorway services and petrol stations
2. Check compatibility
Your car may use:
- Type 2 connector (most common)
- CCS (Common Charging System) – used for rapid charging
- CHAdeMO (older rapid charging standard)
3. Tap to start
Depending on the operator, you may activate charging with:
- Contactless bank card
- App
- RFID fob
- Account login
4. Plug in and begin charging
Connect firmly and wait for confirmation on the charger screen.
5. Monitor charging
Many apps show:
- Current charge level
- Cost per kWh
- Estimated time remaining
6. End session & unplug
Follow the on-screen instructions before removing the cable.
Important: Always move your car once charging is complete to avoid idle fees.
Using a Rapid Car Charger: What You Need to Know
Rapid chargers (50–350kW) provide the fastest charging speeds. Here’s how to use them:
- Use CCS or CHAdeMO (depending on your vehicle)
- Plug the charger’s fixed cable straight into your car
- Charging usually starts automatically after authentication
- These chargers are ideal for long journeys or when you’re short on time
Note: Rapid charging can slow your battery’s long-term health slightly, so use it when needed — not every day.
How Long Does a Car Charger Take to Charge an EV?
Approximate UK charging times:
| Charger Type | Power Output | Time for 0–80% |
|---|---|---|
| 3-Pin Plug | 2.3kW | 12–24 hours |
| Home Fast Charger | 7kW | 4–8 hours |
| Workplace Charger | 22kW | 2–4 hours |
| Rapid Charger | 50kW | 30–60 minutes |
| Ultra-Rapid | 150–350kW | 10–25 minutes |
Actual times depend on battery size and temperature.
Safety Tips When Using a Car Charger
- Avoid damaged cables
- Do not use extension cords
- Ensure the charger is properly installed by a qualified electrician
- Keep your charging area dry and clutter-free
- Regularly check your charging port for dirt or debris
- Enable charging schedules to avoid unnecessary heat build-up
Safety comes first — EV chargers are powerful electrical devices.
Common Mistakes People Make When Using a Car Charger
Avoid the following:
- Plugging into rapid chargers too often
- Leaving the car plugged in after charging finishes
- Using incompatible cables
- Charging to 100% unnecessarily
- Ignoring charger app notifications
Small habits lead to better battery health and lower running costs.
FAQ: How to Use a Car Charger
Do all car chargers work with all cars?
No. Different cars use different connectors, and rapid chargers require compatible fast-charging tech.
Can I use a normal 3-pin plug to charge my car?
Yes, but it’s very slow and should only be used occasionally.
How much does it cost to charge an electric car?
Home charging is the cheapest (often £5–£10 per full charge). Public rapid chargers cost more — usually per kWh.
How do I know when my EV is fully charged?
Your car and charger will stop charging automatically and you’ll receive a notification if using an app.
Is it bad to rapid-charge too often?
No, but using rapid charging daily can reduce long-term battery health slightly.
Final Thoughts: Using a Car Charger Is Easy Once You Know How
