100+ chargers, one campus
The campus at 4, rue de Bitbourg houses BALTHASAR Group, several companies and our own office and showroom. More than 100 chargers run on nested load management: the campus, each building and each tenant has its own limit.

The project
What was built
- Site
- Business campus, Luxembourg-Hamm: offices, warehouses, fleet vehicles, staff and visitors
- Chargers
- More than 100 VOOL chargers
- Load management
- Multi-level and multi-point: several VOOL load management controllers, one for the campus connection and one for each building or tenant, with patented phase switching
- One tenant
- A delivery company: its vans, its office and its warehouse share a 125 A connection
- Charging window
- The vans are parked from 15:00 to 06:00; the controller spreads their charging over that time
- Operation
- AMP X VOLT: platform, billing per charge point, support
125 A
for a delivery fleet, its office and its warehouse
The vans have fifteen hours to charge, so the controller never lets the site's peak rise. A low peak keeps the power-based part of the grid fees low: thousands of euros saved every year, with every van full by 06:00. See grid fees.
What it shows
Load management in levels
A campus has one grid connection, and each building and tenant has its own limit below it. Each controller manages its level and passes on what is left, so one tenant's peak never takes power from another and the campus connection is never crossed.
Most car parks are sized as if every charger ran at full power at once. They never do: cars arrive at different times, need different amounts and leave at different times. See it in the live demo or read about load management.
