Fill what you know. If a value is unknown, keep the practical default and verify the nameplate later.

Battery Capacity (kWh)

Charges Per Week

Average Charge Added (%)

Charging Efficiency (%)

Electricity Rate (â‚¹/kWh)

Use this to estimate how much home EV car charging can add to your monthly bill. Track EV charging separately for cleaner planning.

This is a preliminary planning estimate. For certified audits, use site measurement and nameplate readings.

Is this result exact?

It is an engineering estimate using user inputs. Exact result needs actual meter/nameplate data.

Can I use it for audit report?

Yes, as a preliminary calculation and supporting estimate.

Home EV charging can become one of the top loads. If available, check time-of-day tariff and solar pairing.

The result is a planning estimate. Use nameplate wattage, measured runtime and current tariff for professional-level accuracy.
