Charging points on your own site: plan the capacity before the chargers
Charging points peak precisely when everyone arrives at the same time. Knowing your profile first prevents costly surprises.
Electric company vehicles, employees' lease cars, visitors who expect to be able to charge: for many organisations, charging infrastructure on their own premises is no longer a question but a plan. The pitfall sits one layer deeper: does it fit on the grid connection?
Charging points are among the largest new consumers a business can add, and they peak precisely at the moments when everyone arrives at once. If you know your capacity first and only then install, you avoid expensive surprises. This article describes that order of work.
Why charging is unlike any other consumption
A charging plaza does not behave like a machine park. Cars arrive in clusters, around working hours, and then demand a great deal of power at the same time. Without control, that charging peak lands on top of the building's existing morning peak, precisely at the tightest moment of the grid connection.
At the same time, charging is the most flexible consumer there is: a car that arrives at nine and leaves at five rarely needs to charge at full power. The peak is therefore avoidable, but only if it is known how much room there genuinely is per quarter hour.
Measure first: how much room do you actually have?
The basic question for any charging plan is not how many charging points you want, but how much room the existing profile leaves.
- Map the current quarter-hour profile: where are the peaks and how close are they to the contracted capacity?
- Look at the moments when charging will take place: how much room is there precisely then?
- Run scenarios on the data: what do ten, twenty or forty charging points do to the profile?
- Determine what needs to be controlled: static limiting, dynamic distribution or smart scheduling in quiet quarter hours.
Load balancing is not a luxury but a precondition
Virtually every serious charging plaza needs some form of smart charging: distributing the available power across the connected cars, within the limit of what the building leaves over at that moment. The quality of that control stands or falls with up-to-date metering data from the entire grid connection, not just from the charging points themselves.
Well-planned charging can even work the other way round: shifting charging to cheap or sunny hours turns the vehicle fleet into a flexible consumer instead of a problem.
Conclusion
Charging infrastructure succeeds or fails on capacity planning. If you know your quarter-hour profile first, you know how many charging points will fit, what needs to be controlled and where the room to grow lies.
