We appreciate your insightful comments. In colder weather we have the heater on, EV has to run extra equipment to make the heat which increases energy consumption. IC vehicles produce heat as a by product so while there is minimal extra consumption it is a fact that the motor produces the heat all the time, as an inefficiency of extracting power from the fuel. "Use it or lose it" at it's finest.
Regarding consumption, how come we are obsessed with range? your proposed measurement of 'range per charge" mostly just shows the size of the battery, in a fossil fuel car I could fit a larger tank to adjust the equivalent figure. The bulk of consumers have little knowledge of mpg or l/100k whatever, they work on $ per week or $ to X city, in a naive fashion. Same with their home power account, no one thinks how many kwh they used last month just that the bill was $86. with little concept as to how the figure was reached. Commenters here are the exceptions, mostly consisting of people who think more deeply into stuff. You're able to quote your consumption in different circumstances, so you must be keeping records. I keep a notebook on every car I've owned with fuel, mileage, (oops, distance) etc because I'm pedantic. Well in the minority, like you. I was interested to read Hydrogen cars generally give 100km (60 miles) per 1Kg of hydrogen. I would propose that EV talk about electricity in KWh, because thats how you buy it, so you will have numbers like 20 m/p/kwh and the size of the battery has nothing to do with the number. Except you will know how many KWh your battery holds.

comments appreciated.
