Having an EV charging station at home is a practical solution for all electric car owners who want to be less dependent on public charging stations. As opposed to public charging stations, you always have a free parking spot and free charging at home. Here we’ll tell you what it takes to set up a charging station at your house.
While you can charge your electric car using a regular wall socket, this should be done only in emergencies rather than on a regular basis. The reason being is that the 2.3 kW supplied by your electrical outlet is not enough to charge your EV in a reasonable amount of time. You could be waiting 15 hours or more depending on the type of electric car battery you have. And the plug isn’t really designed to charge a car, which could present a risk if you use it a lot. Even if you do decide to use your electrical outlet, you should have it inspected by a professional to see whether the cable is safe to use for this purpose.
A better solution is known as a wallbox, which is a home charging station for your car. It is generally mounted on the wall or it can be set up as a freestanding pillar. Depending on the model, it can supply up to 22 kW of power. The charging time will vary on the charging speed of the wallbox and the capacity of the car battery. Depending on the model, a wallbox can take between 2 to 12 hours to fully charge the battery of an electric vehicle.
An at-home charging station not only charges your car, some smart models can also regulate the power supply. Smart wallboxes can optimize the charging time, for instance, by charging the car only up to a certain level in order to avoid wasting energy.
A home charging station for your EV consists of several components.
You come home from work, plug your car into the charging station and simply let it charge overnight. This way the battery is always charged whenever you need to use it. It also means you are less dependent on public charging stations. Another advantage is the money you’ll save. Public charging stations often charge more than what you pay for charging at home with your wallbox. You can also take advantage of renewable energies, for example if you have solar panels installed at home. And you don’t have to waste time waiting around for your car to charge at a public station.
You need to make sure you have a suitable power connection. Most charging stations need to connect to a 230-volt grid in order to reach 7.4 kW. A 400 volt power connector will give you charging power output of 11 kW or 22 kW.
The charging power output also tells you whether you will need to get a permit for your new wallbox. You don’t need a permit for up to 11 kW, but you should tell the grid operator about your installation. You must get a permit before installing a wallbox with 22 kW.
Another key aspect is where you put your charging station. Is there an electrical outlet in front of your house or in your garage or will you have to have a new cable put in? The charging station also needs to be located someplace where it’s protected from harsh weather and direct sunlight.
Installing a wallbox also requires technical expertise and experience. For this reason, only electricians with the proper training and certification are allowed to install them. If you try to do this yourself, not only are you risking your own personal safety, but any damage that occurs will not be insured.
The cost of installing a wallbox will vary depending on your personal situation. The type of charging station, the power connection and the distance to the outlet are all factors that can increase the cost of your installation.
Installation can cost up to CHF 2,000. It may cost even more if you need to have a new cable added to your house, for example.
Having a wallbox electric car charger at home offers a number of advantages over a public charging station. It is more practical, cheaper and, under the right circumstances, even more sustainable.
Overall, electromobility is on the rise and home EV charging stations are a big reason behind this trend. The increased demand for electric cars steps up the demand for charging stations, which means the technology will continue to improve.
A wallbox is a charging unit that is specially designed for use in residential garages and carports. It enables EV owners to quickly, safely and conveniently charge their vehicle at home.
How fast you can charge your car at home depends on the power rating of your charging station. Most wallboxes supply 11 kW so they take between 4-6 hours to fully charge an EV. There are faster DC charging stations that have a power rating of up to 50 kW that can fully charge a car in about an hour.
Yes. Many home EV charging stations can be controlled with an app so you can monitor the charging process and select different settings.
