Easy-to-use charging solutions for apartment buildings, such as a wall box in the underground car park, make properties much more attractive. This trend will continue as the proportion of e-mobility rises, because demand is continuing to grow. Charging stations in apartment buildings are an important decision-making factor for an increasing number of tenants and buyers. That's because properties with prepared or installed charging infrastructure are easier to rent and often achieve higher selling prices, which is why installing an e-charging solution for the underground car park is considered a future-proof, value-adding investment in electromobility in Switzerland. Find out more about the benefits of charging solutions in the white paper ‘Charging infrastructure for electromobility’.
Benefits for end users
Users of our charging stations benefit from transparent, convenient billing by app and credit card. Users of our charging solutions for apartment buildings also gain access via the app to our international public charging network.
The Federal Council wants to make it easier to charge electric vehicles at home. The aim is to make it possible in the future to oblige owners of residential properties to install the basic infrastructure for charging electric vehicles if tenants and condominium owners so request. The Federal Council put the relevant amendment to the Energy Act out for consultation on 19 June 2026.

Our charging solutions for apartment buildings have a modular design, so owners and management companies can proceed in stages: Instead of immediately equipping all parking spaces in the underground car park with a charging station for electric vehicles, you can expand the infrastructure step by step and adapt it to actual needs. This ensures that the solution remains both cost-effective and scalable. Intelligent, dynamic charging management ensures that your charging solution grows with your needs.
<>Electric vehicles require a lot more electricity to charge than other consumers in the building. So it's important that the charging infrastructure in the apartment building is controlled by means of a load management system – especially if there are several other charging stations. Charging multiple vehicles simultaneously without intelligent control is not recommended. A load management system for charging stations optimally distributes the available power and prevents the electrical equipment in the building from being overloaded.
How dynamic load management works
Load management automatically coordinates the electricity demand of the e-charging stations with the other consumers in the apartment building, such as household appliances or the IT infrastructure. Charging is usually a secondary priority because electric vehicles often remain connected for a long time, whether at home overnight or at work during the day. During peak loads, charging can be slowed down or interrupted for some time, so there is never an overload.
The connected load of most properties is not designed for charging multiple electric vehicles at the same time. With intelligent load management for your charging solution in an apartment building, you can avoid the cost of expanding connection capacity. You can find more useful information about charging solutions in the white paper ‘Charging infrastructure for electromobility’.
Special requirements apply for the installation of a charging station in an underground car park:
- Fire safety: The guidelines of the Association of Cantonal Fire Insurers (VKF) must be observed. Depending on the underground car park, additional fire safety distances or adjustments to the ventilation may be required.
- Electrical installation: The charging station must be installed by a licensed electrician and comply with the Low-Voltage Installation Regulations (NIV).
- Grid connection: The local grid operator must be informed of the planned installation and issue the grid access permit.
- Ventilation: Depending on the size and use of the underground car park, there may be requirements on the ventilation system.
Contact us for advice on installation in your underground car park.
The legal basis for charging stations in Switzerland is regulated on a number of levels. The following list is not exhaustive:
- Federal level: The Federal Electricity Supply Act (ESA) and the Electricity Act (EleG) form the national basis for grid connections and electrical installations.
- Condominiums : Structural measures that go beyond ordinary management require a majority decision of the condominium owners (Art. 712a et seq. of the Swiss Civil Code (ZGB)).
- Tenancy law: Tenants require the written consent of the landlord for changes to the leased property (Art. 260a of the Swiss Code of Obligations (OR)).
- Cantonal building laws: Cantonal building and planning laws may impose additional requirements.
Depending on the situation, the following permits must be obtained:
- Consent of the owners / management company: In the case of rental agreements, the landlord’s written permission is required. For condominiums, a decision by the owners’ association is required.
- Grid access permit: Connection to the electricity grid requires the permission of the local grid operator.
- Building permit: Depending on the canton and municipality, a building permit may be required – especially for visible outdoor facilities.
- Electrical installation certificate: Once the installation is complete, the specialist installer must issue a safety certificate.
There is currently no standardised funding scheme for private charging infrastructure at federal level. However, funding is possible at various levels:
- Cantonal: Individual cantons offer subsidies for charging infrastructure.
- Municipalities: Many municipalities support the acquisition of charging infrastructure as part of their energy and climate programmes. The City of Zurich also provides support with a scheme.
- ProKilowatt (federal government): The Swiss federal energy efficiency programme may be relevant for larger charging infrastructure projects.
For apartment buildings with multiple charging points, we recommend a scalable system solution with integrated load management:
- Central load management system: Multiple charging points are controlled via a backend that intelligently distributes the available grid capacity, allowing a lot of vehicles to charge at the same time without overloading the building connection.
- Dedicated charging points per parking space: Each parking unit has its own charging point with individual billing per user.
- Visitor parking spaces: Shared charging points are used by multiple users via an app or RFID card or on an ad hoc basis (one-off payment) via a QR code.
- Scalability: Future-proof infrastructure can be easily expanded as demand grows.
Load management ensures that multiple charging stations can be operated simultaneously without overloading the available grid connection:
- Static load management: Each charging point is assigned a fixed maximum charging power and the overall power of all charging points never exceeds the defined limit. This system is restrictive.
- Dynamic load management: The system continuously measures the building’s total electricity consumption and makes the remaining capacity available to the charging points. In the event of high consumption (e.g. lifts, heating), the charging power is temporarily reduced – and vice versa. ewz has dynamic load management system in place in each case.
- Prioritisation: Some systems make it possible to assign higher priority to specific charging points or users.
This allows the existing grid capacity to be optimally utilised without the need to carry out costly grid reinforcements.
Implementation generally follows the steps set out below:
- Analysis of grid capacity: A licensed electrician determines the available connected load of the building.
- Planning of the charging infrastructure: The number of charging points, the locations and the cable routing are determined.
- Dynamic load management, electromobility meters and connectivity access points are installed.
- Installation of the charging points: The charging stations are installed by an approved electrician and connected to the EMS.
- Commissioning and configuration: The system is parameterised (maximum output, priorities, billing logic) and commissioned.
