Hi Everyone!
I purchased a 2015 Model S P85DL in early August and noticed that my electrical bill spiked by a lot more than I was expecting. In my first full billing month since owning the Model S, my off-peak electricity usage (when I charge the car) increased by 700 kWh compared to the same billing month last year (and I wasn't even running my house A/C most of the last month). I just found this surprising, given that:
115,200 = Odometer when purchased in early August:
118,500 kms = Current Odometer
3,000 km = Distance since purchased 1.50 months ago
Of the 3,000 kms, at least 1,000 kms were free supercharging, which means that I charged less than 2,000 kms since purchase at home. This mean that my consumption rate in this billing cycle is at least:
Consumption Rate
= 700 kWh / 2000 kms
= 0.350 kWh / km
= 350 Wh / km
This conservatively-low estimate seems pretty crazy high given that my car's trip computer (which I reset 2200 kms ago) says that I was averaging 211 Wh / km. Nothing else in my home has changed electrically since this month last year. Any ideas? I just downloaded the "Tesla Stats" app on the iPhone and subscribed to a TeslaFi trial to get some more stats to support my investigation. I still LOVE the car!!
