With electric vehicles (EVs) becoming more popular, you might be wondering how car chargers work. If you’re considering installing a home EV charger or just want to better understand the technology behind charging an electric car, this guide is for you. We’ll break down the basics of EV chargers, how they operate, and why investing in a home charging solution can be a game-changer.
What Is an EV Charger?
An EV charger, or electric vehicle charger, is a device that delivers electricity to the battery of your electric car. It’s the EV equivalent of a petrol pump, but instead of fossil fuels, it provides clean electricity. EV chargers come in different types, speeds, and configurations, each designed to meet specific needs.
How Does a Car Charger Work?
The basic principle of a car charger is to convert electricity from your home or the grid into a form that your EV’s battery can use.
Here's how it works:
1. Electricity Source
EV chargers draw electricity from the power grid or your home’s electrical system. In the UK, this typically means a 230-volt single-phase supply for residential properties.
2. Conversion
The charger converts the alternating current (AC) from your home into direct current (DC), which your EV battery uses. Some chargers deliver AC electricity, relying on the car's onboard inverter to convert it to DC, while rapid chargers often supply DC directly.
3. Charging Speed
Charging speed depends on the power output of the charger. In the UK, the most common home charger is a 7kW charger, which can fully charge most EVs overnight. Rapid chargers, often found at public stations, deliver higher power for faster charging.
4. Smart Features
Modern chargers often include smart features such as scheduling, energy monitoring, and remote control via apps, allowing you to charge your car during off-peak hours and optimise energy usage.
Types of EV Chargers
To better understand how car chargers work, it’s important to know the different types:
Type 1 Chargers
- Operate on a standard UK three-pin plug (230 volts).
- Slowest charging option, typically adding 3-4 miles of range per hour.
- Best suited for occasional or emergency charging.
Type 2 Chargers
- Use a dedicated 7kW or 22kW charger.
- Most popular for home installations in the UK.
- Can fully charge an EV overnight.
Rapid Chargers
- Deliver DC power directly to the battery.
- Typically found at public charging stations.
- Provide 80% charge in as little as 30 minutes.
Why Install a Home EV Charger?
Understanding how a car charger works highlights the advantages of having a dedicated home EV charger:
1. Convenience
Home chargers allow you to plug in your car overnight and wake up to a fully charged battery. No more hunting for public chargers or waiting in queues.
2. Faster Charging
Compared to a standard three-pin plug, a dedicated home charger delivers faster, more efficient charging. A Type 2 charger can provide up to 30 miles of range per hour of charging.
3. Cost-Effectiveness
Charging at home is significantly cheaper than using public chargers, especially if you take advantage of off-peak electricity tariffs.
4. Smart Charging
With a smart home charger, you can monitor your charging sessions, schedule charging during off-peak hours, and even integrate with renewable energy sources like solar panels.
How to Install a Home Car Charger
If you’re ready to experience the convenience of home charging, follow these steps:
- Assess Your Electrical System: Ensure your home’s electrical system can support a charger. Most UK homes are compatible with a 7kW Type 2 charger.
- Choose the Right Charger: Consider options like smart features, tethered vs. untethered, and power output.
- Hire a Professional Electrician: A qualified electrician will install your charger safely and in compliance with UK regulations.
- Start Charging: Once installed, simply plug in your EV, and let the charger do the work.

Can I Use Any Charger for My EV?
Most modern EVs in the UK are compatible with Type 2 chargers, but always check your vehicle’s specifications to ensure compatibility.
How Long Does It Take to Charge an EV?
Charging time depends on the charger type and battery size. A 7kW home charger typically takes 6-8 hours for a full charge, while rapid chargers can deliver 80% charge in 30-60 minutes.
