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

  1. Record the charger reference and product rating.
  2. Select single-phase or three-phase basis.
  3. Enter charger current directly where it is documented, or convert from kW with a clear PF basis.
  4. Enter the planning or diversity factor from the project basis.
  5. Carry the resulting current into maximum-demand and switchboard 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.

Questions

Does the EV charger load calculator decide maximum demand?

No. It prepares one charger row. Use the maximum-demand workflow for the whole switchboard or installation record.

Can the planning factor come from this guide?

No. The factor is entered by the user and should come from project basis, load management, charger settings or competent review.
