    I'd also like to hear the answer to this question. In addition, is it hard on the engine after running out of EV at say 55mph to have a cold ICE start?

    Probably why the ICE has 0W-20 oil in it.

    Cold engine starts always include EV-BOOST, even when the EV capacity is totally depleted. That limits RPM to just 1500. So, it isn't that hard on it. In fact, traditional vehicles aren't that fortunate. They don't have a battery & motor to buffer starts. And think about how much less horsepower it takes to maintain a cruise as it does move from a stop.

    So whoever wrote that EV miles are more expensive than gas miles.. that is incorrect. EV miles will always be cheaper unless electric rates go up.

    I think you have to multiply your costs per charge by 1.15 factor to cater for charging losses.

    I did the calculation from my one full year data. If gas price is $3.70, electricity needs to be 26 cents per kWh.

    That's based on my result of 56 MPG gas and 132 MPGe electric.

    "Fuel Costs" ... don't forget to throw in the ancilary fuel costs. Oil ... filters ... etc. Your costs to get down the road should include all your stuff. Similarly, the traction pack has a defined life expectancy that you can throw into the mix on the other side of the numbers. We use over $250 month in juice here in SoCal - only we make it our self - so ... since our system's cost will fully amortized itself in just a couple more months, our juice is pretty much free:
    [​IMG]

    But fuel costs ought to include more than what's in your wallet. What about health costs for burning fuel. How do you calculate national interests (Al Queda ... National Debt/military spending) in the mix. It's way bigger than the paper in the wallet ... unless one is strictly thinking it's just about 'me'.

    I'm charging at 240, is the loss the same?

    Okay.. given the charging losses Giora stated above.. for Southern California Edison:

    Tier 1 CP50M $1.38
    Tier 2 CP50M $1.84
    Tier 3 CP50M $3.11
    Tier 4 CP50M $3.57
    Petrol: CP50M $3.80

    Does it? I think there is a pretty wide range of miles where the battery could potentially fail. And it's even more unknown in the PiP's.

    The main thing is short trips is great for EV if you can avoid the engine coming on. The Prius gaso MPG is not as efficicent during the engine warm-up period, so elec should almost always be cheaper if during first 5 minutes. Longer trips is toss up in your case.

    Typically the traction pack won't fail. They tend to simply loose capacity. So you replace (whether in a standard hybrid or plugin) the pack when the range/mpg loss becomes intolerable. So, you pick you own point. Typically? well ... pick your own number. (Just by virtue of the minimum warranty for example) 100,000 miles? Start there. Or? Some last beyond 300,000 miles. Average the two? What ever, you evetually throw that cost into your prior miles traveled. That becomes part of the cost. The point was that just looking at gas or electricity is kind of a narrow focus when determining what you're out of pocket.

    Not sure if your assumptions cross over to the PiP as easily as you think they do.

    No assumptions here - I'm just thinking folks need to take more into account. Not a requirement - just gives a better oportunity to grasp more accuracy than gas / electricity.

    But for all we know the PiP battery could be useful as at least a standard hybrid battery for 500,000 miles.

    Yes, there's a massive amount of excessive capacity available with respect to HV usage needs.

    Nice photos, but with your thinking you should limit your breathing because your adding to the carbon dioxide foot print

    His breathing does not transfer fossil carbon from the ground to the atmosphere. His exhalations are primarily derived from plants that are already part of the atmospheric carbon cycle.

    Only the fossil fuel used to produce it, transferring stored fossil carbon from the ground to the atmosphere, matters much. And if he was eating synthetic food made directly from fossil fuel, then your point would have more value.
