Managed EV charging capacity
Compare connected charging power with site headroom and your configured EV limit. This assumes functioning load management.

Method and assumptions
- EV allocation = min(connected power, max(0, site limit − other demand), configured EV cap).
- All limits are active power in kW, not kVA. The equal-share illustration assumes every connected point requests power.
Before using the result
- This is a snapshot: building demand and vehicle acceptance change over time.
- Verify phase loading, minimum charging current, metering, controller communications and fail-safe behaviour. A low allocation may require queued or paused sessions; it does not guarantee every vehicle can charge.
- This does not size cables, protection, service capacity or certify charger compatibility.
Worked example
