Everything You Need to Know About EV Chargers: FAQs 
Most frequently asked questions from our customers.

As electric vehicles continue to rise in popularity, so do the questions about home charging solutions. At GreenGenUK, we work with industry-leading brands like myenergi, Rolec, and Ohme to provide efficient, reliable, and smart EV charging solutions. Below, we’ve compiled some of the most frequently asked questions about EV chargers to help you make an informed decision. 

1. What is an EV charger, and why do I need one?

An EV charger is a device that supplies electricity to charge your electric vehicle’s battery. While you can charge your EV using a standard 3-pin plug, a dedicated EV charger is much faster, safer, and often includes smart features like scheduling and energy monitoring. 

2. How fast can I charge my EV at home?

The speed of charging depends on the power output of your charger and your vehicle’s onboard charger. Here’s a breakdown: 

• 3-pin plug (2.3kW): Adds around 8 miles of range per hour of charging. 

• 7kW charger (e.g., myenergi zappi): Adds around 30 miles of range per hour. 

• 22kW charger: Requires a three-phase power supply and adds up to 90 miles of range per hour. 

Most UK homes have a single-phase power supply, making 7kW chargers the most common option for residential charging. 

3. What is a “smart” EV charger?

A smart EV charger, like the Ohme Home Pro or myenergi zappi, connects to your Wi-Fi or mobile network, allowing you to: 

• Schedule charging during off-peak hours to save money. 

• Monitor energy usage through an app. 

• Integrate with renewable energy sources like solar panels. 

 4. Can I charge my EV using solar panels?

Yes! Many chargers, like the myenergi zappi, are designed to work seamlessly with solar PV systems. They prioritise surplus energy from your solar panels, making your EV charging even greener and reducing your reliance on the grid. 

5. How much does it cost to charge an EV at home?

The cost depends on your electricity tariff and the size of your EV’s battery. On a standard tariff, charging an EV with a 60kWh battery (roughly 200-250 miles of range) costs around £15. With off-peak tariffs or renewable energy, costs can be significantly lower. 

6. Is my home suitable for an EV charger installation?

Most UK homes can accommodate an EV charger, but here are the key considerations: 

• Parking space: You’ll need a driveway or garage close to where the charger will be installed. 

• Electrical supply: Your home’s electrical capacity may need to be assessed to ensure it can handle an additional load. 

• Permission: If you rent or live in a shared property, you may need permission from your landlord or housing association. 

7. What grants are available for EV charger installation?

The EV Chargepoint Grant (formerly the OLEV grant) provides up to £350 toward the cost of a home EV charger for some eligible households. If you live in a flat or rented accommodation, you may qualify. 

8. Which EV charger brand should I choose?

At GreenGenUK, we recommend chargers from trusted brands like: 

• myenergi zappi: Perfect for solar integration and eco-conscious users. 

• Rolec WallPod: A budget-friendly, reliable option. 

• Ohme Home Pro: Ideal for tech-savvy drivers who want advanced scheduling and energy monitoring features. 

9. Can I install an EV charger myself?

No. EV chargers must be installed by a qualified and certified installer to ensure compliance with electrical regulations and safety standards. 

10. How long does installation take?

Installation typically takes around 2-4 hours. However, if additional work is required to upgrade your electrical system, it could take longer. 

11. What maintenance does an EV charger require?

EV chargers are low-maintenance devices. Regularly check the unit for visible damage and ensure it’s clean and free of obstructions. For advanced models, firmware updates may be necessary, which can often be done through an app. 

12. Can I charge more than one car at home?

Yes, some chargers, like those from Rolec and Ohme, support dual charging. Alternatively, you can install a second charger if your electrical capacity allows.
