What is an electric car charger?

An electric car charger is an appliance that charges your electric or hybrid plug-in car. As the industry is relatively new, EV car chargers are known by a few different names and commonly referred to as electric car charging stations, electric car charging points, EV wall chargers and wall boxes.

Can I get my own electric car charger?

If you have access to off-street parking (for example a garage or driveway), having your own dedicated car charger to use exclusively for yourself is an obvious choice. You’ll have access to your property’s electricity fuse board and already pay for your energy bills.

For those that live in dwellings with shared parking spaces, you’ll need to talk to your building management to discuss how to get your own EV car charger to use either for yourself or to share with others. As well as figure out who will pay for the installation costs and the energy that you will use.

Those with road parking only are largely left reliant on using public car charging points on the road or at shopping centres or motorway services. Contact Andersen as we may be able to help you work out a way.

What types of electric car charging points are there?

As more electric vehicles hit our roads, the choice and variety of charge points is constantly expanding. Charging speed for electric cars is measured in kilowatts (kW). When choosing a home car charging point, you have three options: 3.6kW, 7kW and 22kW. The greater the power, the faster the charge.

95% of UK homes have single-phase power supply which gives a 7kW maximum power to an ev charger. A 22kW enabled charge point can be installed to charge at either 3.6kW, 7kW or 22kW (with the highest rating only available when there is a 3-phase power supply).

Most EV drivers choose to park and plug-in to a charge point whenever possible so that they return to their vehicle with a fuller battery than when they left it.

To sum up there are four different locations to charge your car.

At home, at work, at public charging points and at motorway services.

Charging your EV at home using a standard 3-pin plug is possible. However, owing to the fact that it takes a long time to charge and the sockets do not have the required safety features of a dedicated charger, they are more commonly used as a back-up charging option when travelling or visiting friends.

A dedicated home or work car charger provides either 3.6kW or 7kW power, or up to 22kW if the property has three phase power supply.

Commercial service charging stations (usually found at motorway services) and some public chargers (usually on the road or at shopping centres) charge from 7kW up to 50kW or more.

50kW charging is known as rapid charging and is useful when you are planning a long trip and you want to charge your vehicle on the way.

How fast can I charge my car?

Most EV drivers want to charge their car in the fastest way possible so for this reason it’s important to understand the three factors that control how fast your car can charge.

Understanding the Three Trinities of home EV car charging

There are three factors are:

  • The incoming power supply to your home or property.
  • The electric car itself – the On-Board Charger (OBC) and the car’s battery size.
  • The EV charger (3.6kW, 7kW or 22kW)

The limiting factor will always be the lowest denominator.

So for example, a Porsche Taycan with an 11kW on-board charger plugged into a 22kW enabled ev charger will draw a maximum of 7kW from a property that has a single phase supply and a maximum of 11kW from a property that has a 3-phase supply.

A plug-in hybrid Volvo T8 XC60 with an onboard battery charger of 3.6kW plugged into a 22kW enabled ev charger will draw a maximum of 3.6kW from a property with a single phase supply and a maximum of 3.6 kW from a property that has a 3-phase supply.

How do I work out the cost of charging my car?

 It’s easy and useful to work out the cost of driving your ev.


Why should I buy from Andersen?

Whether you are an ev driver looking for a dedicated car charger or a business looking to add charging infrastructure, buying an Andersen charger is a good long-term choice.

Think of it as an investment. EV car chargers are known as a fixed appliance and we believe that they should last for years. Andersen are specialists that design and manufacture our chargers from scratch. Our ethos is rooted in a belief that our ev chargers are built to last and similarly the technology within them is built to automatically update so they actually get better with time. In essence, our car chargers raise the bar with what to expect.

What electric car chargers do Andersen supply?

Andersen’s smart chargers include the wall mounted A2 model which is 22kW enabled, comes with an integrated 5.5m evoflek cable and available in 8 different colours and finishes. Andersen’s chargers are UK government OZEV approved and compatible with all electric and hybrid plug-in vehicles.
