Methodology

How the estimate is calculated

The calculator estimates battery energy from usable capacity and state-of-charge change, then accounts for charging loss.

Per-kWh pricing applies the entered rate to estimated wall energy. Per-minute pricing applies the entered rate to session duration. Session fees are added separately.

Important assumptions

  • Idle, parking, tax, congestion, membership, and location-specific fees are included only when entered in the session-fee field.
  • For per-minute pricing, enter a realistic session duration; advertised peak charging power does not establish duration.

Common questions

What to know about this estimate

Why show an effective price per kWh for per-minute charging?

It makes differently structured prices easier to compare for the entered session.

Does this estimate charging time?

No. Use the charging-time calculator, then adjust for the vehicle's real charging curve when estimating a fast-charging session.
