Intelligent charging in apartment buildings. Securing the future.

More charging points, less grid stress:

smart1 combines dynamic load management, prioritizable charging cards, EnergyCloud and the smart1 NEXUS to create a scalable overall solution for residential properties.

The challenge does not begin at the wallbox, but with the intelligent distribution of energy in the building. With smart1, you can make optimum use of the existing grid connection, limit peak loads and create a charging infrastructure that can be planned technically, economically and eligible for subsidies.

• Dynamic load management: Distribute available power in real time and avoid overload.
• Prioritize charging cards: Prioritize important user roles for charging when power is scarce.
• Use EnergyCloud: Automatically incorporate variable electricity tariffs into charging and load strategies.
• Install NEXUS: Cleanly bundle distribution, metering, network and control.
• Eligible planning: Think infrastructure as an overall concept instead of as individual wall boxes.

Charging infrastructure becomes the building standard

Apartment buildings are facing a new reality: electromobility is moving into the underground garage, but the grid connection often remains limited. Individual wallboxes do not solve the problem permanently – they often create new complexity in terms of connected load, billing, user priorities and expandability.

smart1 therefore relies on an overall system: measuring energy flows, intelligently controlling charging points, prioritizing consumers, providing monitoring and preparing the hardware in such a way that subsequent expansions remain easy.

The available connected load is distributed dynamically instead of rigidly limiting charging points

Real-time measurement and control protect the grid connection and supply line.

The concept can be expanded from the first parking spaces to larger charging systems.

Dynamic load management: more charging points without unnecessary grid stress

smart1 load management distributes the available power dynamically and in real time to the charging points. The measuring points, grid connection, supply line and connected consumers are taken into account. In this way, the available energy in the building is used in the best possible way rather than simply being reduced statically.

For multi-party buildings, this means that charging infrastructure can be planned more economically, load peaks are reduced and the system remains manageable even with a growing number of charging points.

performance is continuously adapted to the current building situation.

Charging points from different manufacturers and power classes can be easily integrated.

Local energy sources can be easily integrated into the charging management system.

Prioritization at charging card level: fair charging, important users first

When power is scarce, it’s not just how many vehicles are connected that counts, but who needs to charge. With smart1, charging processes can be prioritized based on users – for example for janitors, standby, pool vehicles, residents or guests.

Prioritization is combined with dynamic load management. This means that an important vehicle receives more power when required, while less urgent charging processes are reduced or postponed. This creates fairness, transparency and more charging power for everyone.

• Priorities per charging card: Define user roles and assign specific charging power.
• Load according to demand: Prioritize urgent vehicles, limit guest or secondary roles.
• More fairness in the building: clear rules instead of manual coordination between residents.

Use variable electricity tariffs intelligently – with the smart1 EnergyCloud

With variable electricity tariffs, electricity prices change throughout the day. This is exactly where the smart1 EnergyCloud comes in: Tariff data, load management and intelligent control work together to identify favorable charging windows and avoid expensive time slots.

In multi-party buildings, this creates a clear advantage: the load is limited, the available power is distributed efficiently and charging processes can be shifted to more favorable times – without exceeding the technical limits of the building.

• Use favorable charging times: Give preference to charging processes in favorable tariff and availability windows.
• Limit the load: Reduce charging power if the building load is high or tariffs are expensive.
• Reduce costs: More transparency and better use of variable electricity tariffs in buildings.

Funding in Germany: planning charging infrastructure as an overall project

The federal program “Charging in multi-party buildings” supports the acquisition and installation of charging infrastructure in and on existing multi-party buildings. Pre-cabling, charging points, grid connection, construction measures and technical equipment can be eligible for funding.

For owners, condominiums, the housing industry and system partners, this is an opportunity to plan charging infrastructure as a future-proof overall concept rather than selectively – including load management, monitoring, control and expandability.

• Up to €2,000 per parking space: Funding depends on the project, funding call and technical design.
• Focus on technical infrastructure: Thinking about pre-cabling, charging points, grid connection and equipment together.
• Funding check makes sense: Always check eligibility, deadlines and requirements on a project-specific basis.
  • Note: Please always check eligibility, deadlines and technical requirements on a project-specific basis in the current call for funding.

smart1 NEXUS: Distribution, measurement, network and control in one cabinet

The smart1 NEXUS e-mobility distributor bundles the central components for charging infrastructure: energy distribution, real-time measurement, network technology, LTE connection and smart1 EASY2 e-mobility EMS. This turns a parking lot into a prepared power zone.

The NEXUS is designed for AC and DC charging infrastructure, battery storage and PV connection. It reduces installation costs, creates order in the infrastructure and makes it much easier to plan expansions.

• Up to 14 AC charging points per cabinet: two connection areas with modular outlets.
• AC/DC-ready: Connection of AC wallboxes, DC fast chargers, battery and PV possible.
• Integrated operational management: Monitoring, reporting, remote maintenance and data evaluation via smart1 Cloud/Portal.

For the housing industry, system partners, car dealerships and electricians

smart1 supports projects where charging infrastructure needs to be planned, installed and operated in a technically sound manner over the long term. The system is suitable for apartment buildings, residential complexes, underground garages, parking facilities and mixed-use properties.

System partners, car dealerships and specialist electrical companies benefit from a clear system architecture, flexible hardware, manufacturer-independent integration and a solution that is easy to explain to owners and property managers.
