Those of you who have interest in electric cars might like these data. They are from my Mustang Mach-E.
This chart shows km driven (as per the odometer) by month, km added to car (from charge records, by month) and the ratio between them.
You can see that in winter, when the heat is on, only about 65% of the km added to the car are used for driving - the other 35% is loss due to running the electric heat, window defrost and heated seats as well as battery losses. In summer, with these things off, regeneration actually allows the car to "use" more power than is added - up to 5% more. It also shows that using the A/C has a negligible impact on power consumption.
