Charging my electric car at home

You’re going to want a home charging point installation in or near to the area you park your electric car in. You can also use an EVSE supply cable for a 3 pin plug socket as an additional backup solution.

  • It is a good idea to choose a dedicated home charging point as it has built-in safety features and is faster.

What is the cost of installing a dedicated home charger?

There is often a government OLEV grant available to help towards the cost of the home charging point and once installed you simply pay for the electricity you use to charge the vehicle, depending on your electricity provider you may often receive a different rate through the night as it may be classed as off-peak.

How long does it take to charge my electric car?

Slow charging

Obviously, this method takes a longer time, some of the bigger Electric vehicles will require anywhere up to 24 hours to fill the batteries when charged in this way. The dainty Nissan Leaf with its 40kWh battery needs almost 12 hours to get it full.

These chargers will normally run at about 3kW, and this is the charger you would occasionally still find at the public charging points in service stations and town centres etc but more often will be the portable type with a three-pin plug used in a domestic electricity supply. The majority of electric cars on the market will receive one of these charging units as standard, but battery packs are getting bigger as the cars advance and most manufacturers only recommend using these chargers when there is no other charging method available. Slow charging is fine if you don’t cover many miles and it provides you with a quick easy way to boost your car’s cells through the night, and the slow charging method creates less heat in the battery, helping prolong life.

Fast charging

This has fast become the most popular charging method available, particularly for domestic users. This method runs at either 7kW or 22kW, the 22kw method is more often used for the public charging points. Most domestic wall boxes will run at the lower 7kW rate, halving the time it takes for a full charge compared with a slow charge.

Using this method you can expect a Nissan Leaf recharge to take about six hours, while a bigger Tesla with a 75kW battery will take approx 12 hours. 22kW needs a 3 phase electricity supply, and they are often a rare and expensive home charging solution, your Electric Vehicle also needs to accept Direct Current (DC) charging along with Alternating Current (AC) method and if so your charging times could be around half compared to the 7kW unit, meaning your Tesla will be fully charged in under six hours.

Managing load on home energy supply

The load on your electricity supply is increased by charging an electric car at home and this load could damage your main fuse depending on the charging rate of both your vehicle and chargepoint.

This can be avoided by using a home charger that will automatically balance the power used by your charging point with the rest of your home, making sure you never exceed the maximum supply available.
