7.4kW vs 22kW EV Chargers: Which One Is Right for You?
As electric vehicles (EVs) continue to grow in popularity across the UK, choosing the right home EV charger has become more important than ever. Two of the most common charging options are 7.4kW and 22kW EV chargers. While both offer reliable charging, the best choice depends on your home, vehicle, and charging needs.
In this guide, we'll compare both options to help you decide which EV charger is right for you.
What Is a 7.4kW EV Charger?
A 7.4kW EV charger is the most popular choice for UK homes. It operates on a single-phase electricity supply, which is standard in the majority of residential properties.
Benefits of a 7.4kW Charger
- Ideal for most UK homes
- Fast overnight charging
- Lower installation costs
- Compatible with almost all electric vehicles
- Energy-efficient and reliable
- Available with smart charging features
A 7.4kW charger is perfect for drivers who charge their vehicle overnight and want a practical, cost-effective solution.
What Is a 22kW EV Charger?
A 22kW EV charger provides significantly faster charging but requires a three-phase electricity supply. Three-phase power is commonly found in commercial buildings and only a small percentage of UK homes have it.
Benefits of a 22kW Charger
- Much faster charging speeds
- Ideal for businesses and commercial premises
- Suitable for fleet vehicles
- Great for locations where multiple EVs are charged daily
If your property only has a single-phase supply, upgrading to three-phase can be expensive and is often unnecessary for most homeowners.
Charging Speed Comparison
| Feature | 7.4kW Charger | 22kW Charger |
|---|---|---|
| Power Output | 7.4kW | 22kW |
| Electricity Supply | Single Phase | Three Phase |
| Best For | Homes | Businesses & Commercial Sites |
| Installation Cost | Lower | Higher |
| Typical Charging Time* | Overnight | Much Faster |
*Charging time depends on your vehicle's battery size and onboard charger.
Does Your EV Support 22kW Charging?
Many electric vehicles cannot charge at the full 22kW AC speed because of their onboard charger limitations. Even if you install a 22kW charger, your EV may still only charge at 7.4kW or 11kW.
Before investing in a faster charger, always check your vehicle's maximum AC charging capability.
Which Charger Should You Choose?
Choose a 7.4kW Charger if you:
- Own a typical UK home
- Have a single-phase electricity supply
- Charge your EV overnight
- Want an affordable installation
- Need reliable everyday charging
Choose a 22kW Charger if you:
- Have a three-phase electricity supply
- Operate a business or commercial site
- Need faster charging throughout the day
- Manage multiple electric vehicles
