Please Check My Calculations/Reasoning

Mon Dec 05, 2016 8:52 am

We have the special PG&E EV rate. Cost is $.11/kWh at night, with rates of .26 and .44 at other times.

Weekdays/Weekends:

If we need to take two trips to town (40-60 miles, roundtrip), the question I needed to answer was: If I am forced to charge at the $.44/kWh rate, is it still cheaper than taking the truck (20 MPG)?

Here are my calculations. I base the efficiency for my Level 2 charger on this:

Here are the calculations:

I conclude that at the highest rate, the fuel cost for the truck and LEAF are about the same. Seem right?

Thanks.

Looks OK. Of course, for me, I would still drive electric even if it were more expensive.

IMHO, the difference of .009 cents for the highest recharge time is not significant. At all other timess, the EV is better. In addition, the maintenance costs per a mile are probably much lower for the BEV than the ICE.
