I have had my Model Y LR for just under four months now and have driven just over 2,200 miles. During this time I have charged the car from three sources: My office (Shell Recharge), Home (Hypervolt) and Tesla superchargers. According to these three sources I have charged the car with 819KwH. According to the lifetime trip meter on the Tesla (never reset), I have used 647KwH. The fact that the car is currently at 80% will account for some of this discrepancy, but not the full 172KwH. The trip screen in the car tells me that my average wH/mile is 286, whereas my calculation has it at closer to 360! I notice that charge amounts for the superchargers and shown in the car are always whole numbers whereas Shell and Hypervolt show decimals, but again rounding is not enough to account for the difference.
Is this a well-known thing? And if so, how do I figure my real consumption?
