Every fleet depot has a moment where the electrician says: "Your feed supports six chargers." The fleet plan says forty. Dynamic load management is how both statements stay true.
The core idea
Chargers rarely all pull maximum power at once. A load-management controller watches the depot's total draw and shares the available budget across chargers — prioritized by departure time, not by who plugged in first.
How it works, step by step
- Each van reports its target state of charge and departure time to your fleet system
- The controller assigns each charger a priority and a power share
- Early departures charge fast first; late stayers fill the remaining capacity
- If the grid limit dips (site load spikes), the system sheds power from the lowest priority first
What you need from the hardware
| Capability | Why it matters |
|---|---|
| OCPP smart-charging profiles | The standard way the controller commands power limits |
| REST API for schedules | Your fleet system sets departures, not the charger app |
| Local fallback controller | Load management keeps working if the internet drops |
| Per-phase metering | You can see exactly where the budget goes |
EMS-Charge depots run this pattern daily — up to 60 charge points on one controller. See the fleet playbook or send us your depot plan.
