How long does it take to charge an electric vehicle at home?

Charging an electric vehicle at home typically involves using a dedicated charging point, such as a 3.7kW or 7kW unit. The time it takes to fully charge a vehicle depends on the battery size and the type of charger used.

Charging Times

• 3.7kW Chargers: These are the slowest but most common household chargers. They usually take around 16 to 30 hours to fully charge a typical 60kWh electric vehicle battery.
• 7kW Chargers: These are more commonly recommended for home use and can charge a 60kWh battery in about 8 to 10 hours, making them ideal for overnight charging.
• 22kW Chargers: Although available, these are less common in residential settings due to the requirement for a three-phase electrical supply. They can charge faster but are more expensive to install.

Practical Applications

For most UK homeowners, charging overnight is a convenient option. A 7kW charger, in particular, can fully charge a vehicle while you sleep, providing a full day of driving.

Pros and Cons of Home Charging

Pros:

• Convenience: Charge your vehicle at home without needing to visit public charge points.
• Cost-Effective: Often cheaper than using public charging points.
• Faster than Public for Full Charges: While public charging can be faster for quick top-ups, home charging is typically more convenient for full charges.

Cons:

• Initial Investment: Requires the purchase and installation of a home charger.
• Slower for Quick Charges: Not suitable for quick top-ups, unlike public rapid chargers.

Common Mistakes

• Underestimating Charging Time: Make sure you allocate enough time for your vehicle to charge fully, especially if you're relying on a slower charger.
• Not Checking Compatibility: Ensure that your vehicle is compatible with the type of charger you install.
• Ignoring Maintenance: Regularly check and maintain your charger to ensure optimal performance and safety.

Real-World Examples

In the UK, many homeowners prefer using a 7kW charger due to its balance of speed and cost. For instance, if you own a 60kWh electric car, using a 7kW charger could mean your vehicle is fully charged by morning, ready for a full day of driving. This setup is ideal for those with regular commuting patterns or who use their vehicles frequently for local trips.
