4mpkwh compared to 6mpkwh is a difference of two. 2mpkwh compared to 4mpkwh is a difference of two. But the difference in consumption between 6 and 4 is an increase of 50%, and between 4 and 2 it’s 100%. Whereas the difference between 2kwh/100km and 4kwh/100km, and between 20kwh/100km 22kwh/100km is the same.Why use such a counter intuitive measure as power/ mile (or km) ??
Surely we want to know how much distance we can cover per KWh as we know the size of battery ?
In other words if my 64KWh battery is 50% full I have 32kwh. If I know I do 4 m per KWH I have a range of 128m - can do that in my head easy.
But if I know I do 13.82kwh m/ 100km - how on earth does that help me?
First I have to convert the battery percentage to KWh (easy and same as other calculation) so using the 50% thing as above I have 32kwh in my battery.
But then I have to calculate 32 / 13.2Kwh (less easy) then multiply that through to another figure to get a range - totally counter intuitive.
Never understood why some people use such a weird way of measuring it.
the miles per “thing” makes you focus on increasingly less important numbers, a car dropping from 10mpkwh to 9mpkwh is unimportant, but going from 3mpkwh to 2mpkwh is catastrophic.
