Charging electric cars in apartment buildings
The increasing number of electric vehicles among apartment unit owners increases the need for charging stations in garages or parking lots of apartment buildings. How many charging stations are needed for an apartment building? As of November 2021, an amendment to the building ordinance requires that electrical wiring for electric car charging stations be installed at all parking garages in new and renovated apartment buildings. This obligation now applies to both new apartment buildings with more than ten parking spaces and renovated apartment buildings. According to Decree No. 266/2021, buildings should at least be prepared for the future installation of charging stations.
We are ready to help you prepare for the near future of electric mobility.
Residential buildings
Every parking space in a new apartment building with more than 10 parking spaces should have the possibility to install its own charging station. Preparations for cable routing should therefore be made.
Think about this requirement already when thinking about the concept and wiring of the apartment building. The number of electric vehicles is constantly increasing and there will therefore be a greater need for charging stations in the future. By installing charging stations, you will increase the value of the housing units and solve the problem of charging electric vehicles.
Other new homes
Similar conditions apply to non-residential buildings. Every new building and alteration to a completed building which has more than 10 parking spaces, except a building for residential use, shall be provided with at least one charging station and wiring for the subsequent installation of an electric vehicle charging station for every fifth parking space if the parking lot of such building is located within the building and, in the case of an alteration to a completed building, the alteration also affects the parking lot or the electrical wiring of the building, or is physically adjacent to the building and, in the case of an alteration to a completed building, the alteration also affects the parking lot or the electrical wiring of the parking lot.
How do I choose a charging station?
The ordinance does not say what capacity the charging stations should have. Common residential charging stations have a capacity of 3.6-22 kW. Charging times for electric vehicles vary depending on the capacity of the battery and how often the car needs to be charged. Even charging stations with a lower capacity can charge most cars completely overnight. A high-performance charging station works very quickly, but remains unused for most of the remaining time. It is therefore advisable to use dynamic power management in the building.
Dynamic power management regulates the actual consumption of the charging stations to avoid exceeding the limits of the wiring and the reserved power. It will allow parts of the charging stations to operate quickly when needed. However, it will keep the overall charging impacts at low power levels
In buildings with dynamic power control, the correct value of the main circuit breaker must also be selected. Recommended values vary according to the number of parking spaces in the building.
How to measure consumption?
You can measure the consumption of each charging station separately. In this case, each charging station is a separate point of consumption and has its own contract with the distributor.
You can have a common metering for all charging stations in the building. The individual stations have sub-meters that belong directly to the owners of the parking space.
