Hybrids and fully electric cars are becoming more common, with their numbers projected to grow significantly in the 2020s. Electric transport plays a major role in meeting the energy-efficiency and emission targets related to traffic.
Thinking about getting a charging station for your home? View the service provider’s different options. If your charging solution would require changes to the electricity connection of your property, we are happy to help.
Electric car types
Fully electric car powered solely by an electric engine
A hybrid powered by a combustion engine and an electric engine, which can be connected to the electricity network for charging
Electric car charging options
As a rule, electric cars are charged at home, mostly overnight. In order to find a suitable charging solution, it is important to find out the capacity of the electric system of your property as well as the type of solution that is best-suited to charging your vehicle. You should carefully consider the locations and number of the charging stations in your housing cooperative.
It is a good idea to have a professional verify the condition and dimensioning of the electric system. If the dimensioning is insufficient or the components are in bad condition, they may cause a fire or electrical safety hazard if subjected to long-term loading. Increasing the capacity may necessitate changes to the property’s electricity connection and main distribution board.
In the case of a detached house, the charging solution is easy to implement as long as you only need one or two charging devices. That said, the charging system may require the main distribution board to be changed or expanded. It may even be necessary to build an entirely new connection for the charging equipment. If that is the case, you should make provisions for future requirements.
The construction of charging stations requires a decision by the housing cooperative. The charging devices can be acquired as required or all at once for all parking spaces. To start with, the easiest solution is to build a number of charging stations, which does not necessitate changes to the property’s electric system.
If the electric system does not have enough capacity to add charging stations, it is necessary to extend the property’s electricity connection, service cable and main distribution board and to implement new cable outputs from the main distribution board to the charging equipment. A fair distribution of the costs between the residents is an important consideration. It is also possible to implement a new electric system for the housing cooperative’s parking lot so that the property’s existing electric system does not need to be changed.
Acquiring a charging station for your electric car
Contact your car dealer or charging operator to find out the type of charging equipment you need.
Get in touch with an electrical engineering professional to find out whether the condition and dimensioning of your property’s electric system permit the installation of the equipment.
Contact your electricity network provider to find out if your electricity connection supports the installation of charging equipment.
If changes are needed, anticipate future charging requirements.
Use a professional electrician or equipment supplier to help with the design and installation of the charging equipment.
How far do you get with one charge?
Depending on the charging equipment and car, one hour of charging enables you to drive anywhere from a couple of kilometres to 100 km. You can achieve longer driving distances with quick charging equipment.
How long does the charging take?
The charging time depends on the charging equipment available to you as well as the car. Most of the charging equipment takes one night or a work day to fully charge a hybrid. For full electric cars, the charging time varies from a few hours to more than a day.
What kind of electricity connection will you need?
The size of a one-family house is usually 3x25A, with a maximum power of 17 kW. Typically, the charging equipment of an electric car uses 3.7–22 kW. If the connection power is exceeded, it will result in the main fuse burning. You can prevent this by limiting the charging capacity, acquiring load control or extending the electricity connection.
The table below shows the connection capacities and the maximum capacities of the charging systems. If the connection is also used for something other than charging an electric car, it requires a charging capacity control system to avoid over-increasing the electric load.
Charging system’s maximum capacity
1 x 11 kW (3x16A)/4 x 3.7 kW (1x16A)
1 x 22 kW (3x32A)/2 x 11 kW (3x16A)
1 x 22 kW (3x32A)/3 x 11 kW (3x16A)
2 x 22 kW (3x32 A)/3 x 11 kW (3x16A)
2 x 22 kW (3x32A)/4 x 11 kW (3x16A)
3 x 22 kW (3x32A)/6 x 11 kW (3x16A)
3 x 22 kW (3x32A)/7 x 11 kW (3x16A)
4 x 22 kW (3x32A)/9 x 11 kW (3x16A)
6 x 22 kW (3x32A)/12 x 11 kW (3x16A)
