Input reference and sample values

Use the units and choices shown for each field. Sample values are provided for practice, not as recommendations.

InputFormat and unitsSample
Energy to addNumeric value. Unit: kWh. Zero or positive.40
Average charging powerNumeric value. Unit: kW. Must be greater than zero.50

Result for these sample inputs

0.8 hours

Select Try the example in the form to load these values and calculate them again. This replaces the current form inputs. Compare the result with the method and worked explanation below.

The method, explained

Ideal charging hours = energy/average charging power.

A WORKED EXAMPLE

Using energy to add = 40 kWh, average charging power = 50 kW, the result is 0.8 hours. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Use average delivered power, not peak advertised power; tapering can dominate. Planning arithmetic based on your inputs. It does not include live traffic, road restrictions, fares or service availability.
