Solutions for your house

There are many questions a prospective electric car owner needs to answer. How should I design the charging site? Is a wall outlet good enough or should I get a special charging box, or"wall box"? Do I need to secure the House? How much does an electric car draw?

Charging cable or charging box?

What's the difference between the charging cable that came with the car and a charging box? Nothing. Despite the name, none of them contains any charger-it is the built-in charger in the vehicle that is used in both cases. What they provide, however, is electronics that monitor the charge and break the power if something is wrong.

As the charging cable has a standard wall socket on the end of the cord, it usually limits the charging current to 10-13 A – more should not be pulled from an unknown wall outlet. Charging boxes, on the other hand, are typically attached to new wiring with its fuse, and therefore, it dares to release more power. It makes the carload faster.

Many electric car owners use the charging cable that came with the car to charge at home from a wall outlet and get along nicely with it. Some even leave the cord plugged into the wall socket and have acquired an extra charging cord to carry with them in the car. Others find it convenient with their charging box.

Do not try to install the electricity yourself! Ask an electrician to install the wall socket for you, with your wire drawn to your fuse in the fuse box. The few thousand it costs to pay off in the long run in terms of safety and convenience. And charging boxes should always be installed by electricians without exception.

Make sure that the charging box or lump on the charging cable is undercover! Even though they are allegedly waterproof, several electric car owners have faced problems with moisture damage.

How much electricity?

If you charge the car via the charging cable, most electric vehicles usually pull about 10-13 A from the wall outlet. If you charge ten hours (one full night), you can charge 20-30 kWh of electricity to the car's batteries, which corresponds to about 10-20 miles of range. Roughly speaking, a kWh of electricity costs approx 0,1 €. Charging boxes usually deliver 16 A to the car, with faster charging as a result.

If you can adjust the power, either via the car's settings or via adjustable charging cable or charging box, you should set the vehicle to slowly charge up throughout the night, rather than the vehicle quickly charging up in an hour and then fully charged for the rest of the night. It feels both the car's batteries and your mains in your house better off.

Thanks to energy-saving lamps and cheap appliances since the turn of the Millennium, most houses have electricity capacity over which is enough to charge an electric car. However, if you install the charging box and plan to charge with high current strength, you may need to raise the main fuse on the housing.


If your car is capable of three-phase charging, you should pull three phases to the charging point. Three-phase charge loads the power grid of the houseless. Either you can mount a three-phase socket and use the car's charging cord, or mount a charging box that can withstand three-phase charging.

Reduce the risk of fire

Keep in mind that the property owner may need to adapt the electric power plant for charging electric cars to reduce the risk of fire when charging an electric vehicle.
