Install charging columns for electric cars at home

Which column power to choose, at home?
With an output of 11 kW, you can fully charge your electric car in 6-8 hours. If the power is only 3 kW, charging takes longer accordingly. The actual charging speed depends on the weakest link in the chain. An electric car with only 3.6 kW of power will not be charged faster, even with an 11 kW charging station. Ideally, the charging station and the car should have the same maximum power.

When buying an electric car or charging station, attention should be paid to the power. The TCS car search helps you here – with the technical data of all vehicles and tips for suitable charging stations. The electrician will also check if the networks in your home meet the requirements of the desired charging station.

Equally important: fast charging. The required DC link (CCS or CHAdeMO) is present on most electric cars or can be installed later.
At home, it should be possible to fully recharge in 6-8 hours. To charge 20 kWh of electricity, required for a range of 100 km, it takes two hours of charging with a power of 10 kW. As a result, those who can only charge with 3 kW wait more than 6 hours.

If I am a tenant or co-owner, can I install a charging station in the building where I live?
For the owners of a single-family home, installing a charging station does not pose major problems, but things get complicated for condominium properties (PPP) and tenants who park their vehicle in an underground car park. The owner of a PPP must obtain the unanimous permission of the assembly of condominiums. The tenant, on the other hand, must have the permission of the landlord. To obtain the owners’ agreement, a well-structured technical dossier should be prepared, which shows how you intend to proceed.

For example, an electrical system in a 9-apartment condominium with underground parking with 80 A (amps) current holds one 11 kW column or three 3.7 kW stations. However, if you want to increase the number of charging columns, the situation becomes more complicated. In general, it is advisable to provide for the strengthening of the electrical connection of the building. If you are also planning to connect a large number of electric cars, you should opt for intelligent charging stations, which detect the load on the electricity grid.
