    The extended range F-150 battery charges (not capacity) 150kWh for 300 miles range.

    So MPGe is about 67, one kWh electricity runs about 2 miles. Operating cost is super low for those without crazy electricity price.

  3. Not bad for a 4x4 truck of its size.

    Not that I'm disputing those figures, but wondering how you got them? Is there a source?

    Guess we'll have to buy a few more solar panels. No big deal!

  6. If you're not limited like we are in Louisiana. The most we can put up for residential is 6kW worth. I wanted my entire roof covered when they told me about the limit. So only a large portion of one side has them.

    That's too bad. I guess the clout of the power company can't be underestimated.
    I'm not allowed to put in more PV than I can use, however, I've known people who put in more with the claim that they were going to have 2 EVs and got that approved, even before they got the 2nd EV.
    It would be great to find a way to clean up that fixed 6kW maximum.
  9. Under technical specifications on the Ford website it lists a 15% to 80% charge in 19 hours at 32 amps 240 volts.

    19*(32*240)/1000)=141 kw hr. If we assume 90% charging efficiency we get 141*.9=131 kw to the battery. Given that is 65% of the battery (80-15)=65. That would make the extended range battery 131/.65=202. That's one big battery!!!.

    For a 300 mile range that would give a miles /kwhr of 300/202=1.5 mile per kwhr. That's not great numbers but its a big truck. I will be charging over 95% of the time with existing solar panels so that not a big concern for me, But if your paying for electricity it's going to cost 2-3 times as much as a Hyundai Kona, or a Tesla model Y. On the other hand its still significantly less than any ICE Truck. if you assume $.08/kw for TOU charging rates. That's ~$11 for a 65% charge or ~$17 for a full charge of 300 miles, or $0.06/mile. If your average tuck ICE gets 18 miles per gallon at $3.50/ gallon that's $0.19/mile or over three times the cost per mile of the Lighting. If you were to drive both trucks for 250000 miles you would save over $32,500 and that's not including the savings for oil changes tune ups and other engine maintenance.

  10. Bingo. That is the germane comparison. If you want a truck, you have to expect to pay for truck energy.

    From Electrek: 19.2kW * 8h = > 150kWh which is 85% of 170kWh - 180kWh

    19 hours is from 15% to 100%, not 15-80%!!!

    In addition, charge current would drop after 80%, and would drop to really low when after 95%. So instead of charging 141kwh, it is more like 125-130kwh. If we assume it is 130kWh, then charged capacity is 152khw, close to what the other website estimated.

    Also, charge efficiency does NOT matter, let's forget it. The truck pulls 33.6kwh from grid and drives 67 miles, it is 67 MPGe. Let's don't get confused.

  14. Thanks for catching that. You are correct on the 15-100%. I was look at the dc charge info for the 15-80%. So that would make the battery closer to 176kwh with 1.7 miles per kWh.

    In my experience ac charging does not drop off at 80% like Dc charging because the amp rate is so much lower to begin with. Dc at 150 kw and 400 volts is 375 amps vrs 32amps for ac. My Kona holds 32 amps all the way to 100 % on ac charging. The lighting could be different but I haven’t seen any specs on it yet.

    I agree with you that the charging efficiency doesn’t matter because you have to pay for all the electrify you use whether it goes in the battery are not. On the other hand if your trying to back calculate the battery size it’s important. My calculation are more for curiosity sake, since Ford has not released the the specs yet. I have seen media estimates between 145 and 180 kwh. It will be interesting to see what the actual specks are hopefully today with the release of more info from Ford.
