I got a Model 3 LR AWD at the end of 2018, and I've been tracking kWh used from the wall, based on the meter built into my EVSE. So far I'm at 2262kWh for 4164 miles driven (with only a very small amount of charging elsewhere). This gives me 543 Wh/mile, while the car odometer reports 1507kWh used while driving, for 363 Wh/mile. This is a very significant difference, almost 50% more from the wall (i.e. purchased) vs what the car reports as used while driving. To recap:

• Wall meter: 543 Wh/mile: 2262kWh for 4164 miles driven
• Car: 363 Wh/mile: 1507kWh for 4164 miles driven

Without getting into the why yet, I'm curious - for anyone else who is similarly able to track these numbers (either via something like TeslaFi, or a separately-metered EVSE) what is your Wh/mile efficiency from the wall (not what's reported by the car?)

Thanks,

p.s. I think this is different from the "charging efficiency" threads - I know that some of the loss is due to charging efficiency, but I'm seeing a much bigger delta than what's expected for charging losses at this point.
