EV and maximum demand
How to carry EV charger load rows into Australian maximum-demand and switchboard-capacity worksheets without double counting.
Demand workflow purpose
EV charger load planning is only one row in a wider demand record. The maximum-demand worksheet needs the EV row, other loads, phase context and project assumptions together.
The point is traceability, not automatic supply-capacity approval.
Workflow
- Use the EV charger load calculator to prepare the charger row.
- Add the row to the switchboard or installation load schedule once.
- Record any load-management or diversity basis beside the EV row.
- Run the maximum-demand worksheet with all relevant loads.
- Review switchboard, phase, DNSP and project constraints separately.
Demand record table
| Field | Record | Review concern |
|---|---|---|
| EV load row | Planning current from EV calculator | Avoid duplicate entry |
| Load-management source | Charger setting, controller or project basis | Controls the planning factor |
| Switchboard context | Existing board or new design | Capacity review is broader than EV |
| Phase allocation | Phase or phases used by charger | Single-phase load can affect balance |
| DNSP context | Network or supply condition | May affect project review |
Boundaries
- Do not use EV row current as a full maximum-demand result.
- Do not count the same charger twice.
- Do not hide load-management assumptions.
- Do not treat maximum-demand output as a supply upgrade decision by itself.
