EV charger load planning
How to prepare charger rating, phase, voltage and planning factor inputs before using the Australian EV charger load calculator.
EV row purpose
An EV charger can materially change a load schedule. The first task is to record the charger rating, phase, voltage and planning factor as a clean row before a whole-board review.
The EV calculator does not decide whether supply capacity is sufficient.
Workflow
- Record the charger reference and product rating.
- Select single-phase or three-phase basis.
- Enter charger current directly where it is documented, or convert from kW with a clear PF basis.
- Enter the planning or diversity factor from the project basis.
- Carry the resulting current into maximum-demand and switchboard review.
Charger row table
| Field | Record | Review concern |
|---|---|---|
| Charger reference | Circuit or charger label | Keeps the row traceable |
| Rating basis | kW, kVA or current | Must match product data |
| Phase and voltage | 230 V single-phase or 400 V three-phase context | Changes current conversion |
| Planning factor | User-entered project basis | Not supplied by the page |
| Load row output | Connected and planning current | Feeds wider demand review |
Boundaries
- Do not treat one EV row as whole-site maximum demand.
- Do not hide load-management assumptions.
- Do not infer DNSP requirements from charger current alone.
- Do not use charger power without checking phase and voltage basis.
