Most fast charging sites are commissioned with a static load management scheme: divide the grid connection by the number of connectors, cap each one, done. It is easy to reason about and it never trips the main breaker. It also throws away a large fraction of the capacity you are paying for.
Where the waste comes from
A static cap has to be sized for the worst case — every connector occupied, every vehicle drawing its maximum. That case is rare. In normal operation you get a mix of vehicles at different states of charge, with wildly different charging curves, arriving and leaving at different times.
- A vehicle at 80% SoC tapers to a fraction of its peak draw, but the static cap still reserves full power for it
- A 50 kW-capable vehicle sitting on a 350 kW connector strands 300 kW
- An idle connector reserves nothing to anyone
The result is a site that reports high utilization on paper while the actual metered draw sits well below the connection limit for most of the day.
What dynamic allocation changes
Once allocation is driven by what vehicles are actually doing rather than by a fixed table, the reserved-but-unused power becomes available to whoever can use it. In practice that means shorter sessions for drivers and more kWh sold per hour for the operator, from exactly the same grid connection.
The interesting part is that this is a modeling problem, not a hardware one. Nothing on site changes.
Seeing it on your own data
We run this as a digital twin simulation against historical CDR data before any deployment, so the before-and-after is measurable rather than promised. If you want to see the numbers for one of your sites, get in touch.
