I had a quick question that I figured some of you experts would be able to answer. So I got my dedicated SDGE TOU meter hooked up and used it for the first time yesterday. I plan on keeping very detailed notes/diary to track the usage, miles charges and kWh charges by SDGE. It's easy as the meter started out at 0.00. So I plugged it in to start after 12:30 AM when I have super peak rates. On Tesla's website: Tesla Charging | Tesla Motors They estimate that charging it 170 miles with a HPWC with dual chargers would use about 55.9 kWh and take about 2 hours 53 minutes to charge. Well, I charged exactly 168 miles (I couldn't get it exactly on their estimator) yet I went out to look on my SDGE meter and it says I used 66 kWh of power last night. If it was a smaller difference I wouldn't care but does anyone know what accounts for such a big percentage difference with what Tesla says would be estimated and what was actually charged by SDGE? I'd really appreciate some thoughts as it got me curious. Thanks in advance.
