We fall in the camp of needing 100 miles per day useable, due to commutes.
In crunching numbers the costs aren’t so rosy or simple.
Firstly, that’s a typical run of around 2500 miles a month. With charging losses, your looking in the range of 900kwh per month.
TOU isn’t a panacea and may be detrimental to your solar net metering. TOU peaks in early evening 4-8PM, right when you geTbhome and crank up the AC. It also con insides with very low efficiency on your solar.
As others pointed out a Prius is ~50mpg, which equates to 50 gals of gas. At $4-$5/gal that’s $200-$250 a month. At 18 cents a kWh, that’s $162 not including other charges (like having dedicated electrical put in). If your not on TOU, your pretty much talking tier 4 rates, err, now tier 3 since only three and next year tier two since only two. I’m assuming with a car you can wiggle out of super user surcharges.
Either way, currently 37-40 cents per KWh. Which would run a $300 Electric bill.
I just checked SDGE, they have a much friendlier TOU structure for EV. 46 cents peak of noon to 8pm, 22 cents off peak, 18 cents super off midnight to 5am. SCE is 48 cents peak 2pm to 8 pm, 31 cents off peak 8am to 2pm and 8pm to 10pm and super off of 12 cents (10pm to 8 am). Since I wouldn’t be waking out to plug my car in at 10 pm, quite a bit of that is going to hut that 48&31 cent rates.
