Ah! See with just a bit of help, we eventually understand each other. I love these cut-away drawings done by Kevin Hulsey (who has allowed me to host them on my site). That's the entire drive train. No gas tank or exhaust, of course. And look at that complicated transmission! Oops. There isn't one. The big box under the hood is where the controller is (along with some very large fuses and capacitors - but it is mostly empty now since that is also where the charger used to be.By inside I meant engine, well anything inside the "body" of the car particularly under the hood
Again I know the answer, but a gasser Rav4 gets what 25mpg if your lucky. So it cost about $3.00 in fuel (or what ever a gallon is when you read this) to go 25 miles. If you were paying for electricity to go 25 miles how much would that be at say $.10 kw or even $.20 a kw?
Lots of ways to look at this.
I think you are right on the money with assuming 25mpg for the gas version. And we'll be generous and say $3/gallon gas. So that's 12c/mile (just for the gas mind you. We're ignoring oil changes and tune ups, of course)
The Rav does about 250 Wh/mile from the batteries. I'll be generous and go 300 Wh/mile from the outlet. That's 3.33 miles for every kWh you buy. At 10c/kWh we're talking about 3c/mile in electricity. at 20c/kWh we're obviously twice that at 6c/mile. So worst case scenario for the EV is half the cost of the best case for the gas car.
But of course when you figure in Time of Use metering, and pay just 5c/kWh like we do here during off-peak times... surprise! 1.5c/mile in fuel.
But then we all know that this isn't just about the money, now is it? My car holds the energy equivalent of about one gallon of gas. And on that one gallon of gas worth of energy, it can silently travel over 100 miles.
