But both are measured from the battery, not from the grid into the battery.
I’m not sure how other brands compare, but I’m pretty impressed by the 95+% grid/battery efficiency over the past 55k miles in the Model 3 (according to TeslaFi at least)
My grid average per mile is 317 w/mi which is pretty impressive considering my pretty high speed commute (cruise at 83 for the majority of the miles)
Car usage average is 302w/mi
