Load balancing FAQ

Load balancing keeps the charger inside the headroom the rest of the building leaves behind. It matters most where heat pumps, solar, batteries or several charge points share one grid connection.

What is dynamic load balancing?

Dynamic load balancing adjusts charging power in real time to what the rest of the building is drawing. When other loads rise, the car eases back. When they fall, the car ramps up again.

When do I need load balancing?

Use load balancing when the grid connection is tight, when more than one charger is installed, or when the building runs heat pumps, HVAC, professional kitchens, workshops or batteries on the same supply.

Does load balancing matter for design?

Yes. Plan it at the drawing stage and the cabling, the cabinet and the charger placement all land where they should. Plan it late and the fix becomes visible — extra enclosures, surface conduit, or a charger moved off its intended spot.

What load balancing systems does Veton support?

Static load balancing is included out of the box. Dynamic load balancing runs through an external meter or an energy management system. The charging controller is the Phoenix Contact CHARX series, OCPP-compatible and grid-aware. It integrates with the Xemex SCC and with energy platforms including Qbus Luqas, Niko Home Control and LifePowr FlexiO. Built-in load management covers sites up to ten charge points. Larger sites add the Veton® load management device.

What about larger sites?

For apartment buildings, depots, workplaces and charging hubs, Veton offers its own load management device. It runs on-site and scales past 100 charge points. Power is shared fairly across every charge point and across all three phases, so a single-phase car never blocks the other two. The whole site stays under its grid connection and its monthly capacity-tariff peak, adapting in real time as the building’s other loads change. No cloud connection required. No monthly fees.

How does Veton protect my home fuse?

Fuse protection is always on, in every mode. It is a safety limit, not an option. The charger keeps the car inside the headroom the rest of the building leaves behind, easing back when other loads rise and ramping up when they fall. It is three-phase aware and limits on the busiest phase. Where several chargers share one supply, the available current is split fairly between them.

Can I prove the savings before switching systems?

Yes. The Veton® load management device can run a shadow trial. The controller watches the site for about a month without touching the chargers, computing every decision it would have made. At the end it returns a PDF estimating yearly savings on energy cost, capacity-tariff peak and self-consumption of solar. Switch it on and the same controller takes over. Nothing to reinstall.
