Nope. The car only is able to measure how much went into the battery. If you have a smart charger then it should have a way to measure what is drawn from the grid, but if you don't have one of those you could track your electric meter as an approximation. It won't matter though: in my example above since the Mach-E is so much cheaper to run the 10% overhead is basically just a rounding error.Re the power draw from the house (source), does the car know this? I guess not. The EVSE should know it, or seems like it could at least know it. I guess this kind of data is the value-add of some of the higher end EVSEs.
