Calculate energy from a state-of-charge window

Battery capacity multiplied by the percentage-point increase gives battery energy added.

Include charging losses explicitly

Energy drawn from the grid can be higher than energy stored in the battery.

What an average-power charge-time estimate means

Energy divided by power gives time only when power is treated as an average.

Estimate home charging cost

Use grid energy and the marginal electricity price relevant to charging.

Convert consumption into trip energy

Distance multiplied by kWh per 100 km gives an energy estimate for the route.
