I am a new Tesla owner and am now just getting a wee shock of the cost of charging my car. It seems as though the cost I thought I was going to pay for electricity is quite a bit more than what I thought it was going to be. I am on E-7 which is supposed to be one of the best schedules available by PG&E (and I understand it is going away soon). I thought I would be paying mostly the low off-peak baseline rate. That isn't happening. Here is my 'logic' as to why charging nightly saves charging costs over charging less often and letting the battery go down over a few days until charging.
We have a Winter daily baseline rate of 8.5 kWh. We have a winter off-peak baseline rate of $.118 but it goes up to $.15 then to $.20 and finally to $.27.
In summary (daily off peak):
0 - 8.6kWh $.118 per kWh
8.6 - 11.05 kWh $.15 per kWh
11.05 - 14.36 kWh $.20 per kWh
14.36 - 18.67 kWh $.27 per kWh
So, if I understand this correctly, if I wait until my battery is depleted to charge I run the risk of hitting the high baseline rate on that day which would be far more expensive then just staying at the lower tiers daily.
Is this logic making sense? Since I am new to the 'Tesla Family' I am just trying to understand how to charge at the lowest cost at home.
Cheers
