I finally got my first full month's SDG&E bill. I drove 582 miles* for 187 kWh and $17.25, including all taxes and fees. Compared to driving our gasoline car that's like buying gas at $0.72/gallon. I was experimenting with the charger and timers so I used "only" 93% at super off-peak rate. If I need a range boost during peak rates that's like buying gas at $2.53/gallon, so it still makes more sense to press the charge button than to fire up the gas burner if that's what it takes to reach a destination.
They read the meter again today so I should have another bill pretty soon. I asked the meter reader and he also had no clue why SDG&E puts in the EVSE meters "backwards." That is, the whole house main meter which is not billed as TOU, displays TOU data. But the EVSE submeter which is billed as TOU, does not display TOU data. Assuming that SDG&E's intent is to use TOU pricing to persuade people to use electricity more in super off-peak, it seems like they are working strongly against their own interests by withholding the crucial TOU data. Oh well, I guess Blink data is good enough.
*Note: I estimated miles driven during the billing period. I hadn't realized that CarWings not only understates kWh, it even understates miles driven. I need to check the odometer around meter reading dates.
