The Ultimate Home Charging Guide

How do you charge an electric car at home?

Most electric car owners use a home charging point. These are dedicated devices that you install so you can plug in and charge when you’re at home. They’re weatherproof and are specially designed to safely charge your electric car.  

Home chargers use a normal domestic electricity supply (known as a UK domestic AC single phase supply) to give speeds of up to 7kW.

How long does it take to charge an electric car?

If you drive a Nissan LEAF with a 39kWh battery, for example, it takes around seven and a half hours to fully charge – and that charge would give you 168 miles of range. 

It’s rare to fully flatten a battery, though, so it’s unlikely to take that long. Most drivers keep their cars at 20%-80% to look after the battery.

When is the best time to charge an electric car?

For most of us, the cheapest and most convenient way to charge is overnight. You’re at home and energy tariffs can be cheaper. This is also the time of day when more of the grid’s energy is coming from renewables – but this changes according to your energy company and tariff.  

How do you install an electric car charger at home?

Once you’ve decided which charger is right for you and whether you’re eligible for an OZEV grant, it’s time to pick an installer.

To install Indra Smart PRO chargers, we partner with Plug Me In, who can install across the whole country.  

Our installers will start by visiting you to check over the details. This survey means they can do the essential electrical safety checks before they set a date to fit your charger.

Sometimes you might need to upgrade your distribution board or other electrical components first, but your installer will explain the details. 

They’ll also agree where to install the charger with you. They need to follow electric car charger installation guidelines and the latest regulations, as well as checking where your nearest power supply is and making sure you can park off the street.

Then on your installation day, they’ll fit your charging station and make sure the charging cable is in a safe place. It normally takes about three hours, but it’s a good idea to be available for the whole day just in case.

Before they leave, they’ll register the charger, set up your details and carry out various tests to make sure things are working properly. Then they should show you how to use the charger and how to install the app, as well as help you download the app onto your phone, tablet or computer. As it’s a smart charger, you can check it and control it with the app whenever you’re online.

Can home car chargers use energy from solar panels?

 

Yes they can – and it can make a big difference when the sun is shining. But you’ll need to do your homework first…

First, you’ll need a solar-compatible charger. Some just work, others need a bit of extra hardware and some don’t work at all.

Second, you’ll need enough power from your solar panels to charge your car and your house. As a rule of thumb, you should aim for about 8-12 panels facing in a direction that gets plenty of sun. This should give you enough power – for example, the Indra Smart PRO charger needs a minimum of 1.4kW/6A to charge a car.

Then – once you’ve got the right charger and you’re generating enough power – you can drive your sunlight-powered car!

How much does it cost to charge an electric car at home?

It depends on your tariff but you can charge for as little as 2p per mile.

A lot of electric car drivers choose an off-peak tariff which is cheaper at night (though more expensive during the day). That’s because there’s less demand for energy in the middle of the night, so it’s much cheaper to buy. And if you’ve got a smart charger you don’t even need to turn your charger on or off during the night: it just happens automatically.

They’re not very popular yet, but some energy suppliers also offer variable tariffs. These use smart technology to change your prices depending on how much demand there is. 

Can you power your home with an electric car?

Using a car to power your home is called ‘V2H’ or ‘Vehicle to Home’ technology. This promising new technology lets you use your car’s enormous battery to power your home.

As well as being very useful during power cuts and unexpected outages, it also lets you store up either solar power from your roof panels or off-peak electricity you’ve bought cheaper at night.

There have been several trial schemes already but it hasn’t yet come to market.

Do home chargers have any common problems?

According to the experts at Indra, there are two common problems. The first is when a charger’s internet connection isn’t good enough. The charger will still work but you won’t be able to use the charging app. In this case, they recommend running a cable to your charger for internet.

The second is ‘nuisance tripping’, when the charger keeps turning off – normally because of something happening with your home’s electricity supply. Advanced chargers like the Indra Smart PRO have technology to deal with the problem.
