    I think Ford now see many of us will reach the maximum lifetime 999mpg on our gauges. Turning that gauge to zero after that may screw the computer up. My lifetime MPG is 353mpg now and growing fast.

    CmaxVsPrius, I've never used my heater/defroster to supercharge, I just assumed it would work. I know the heater/defroster uses more energy than just the A/C, but it is strange that the range gauge drops like it does without supercharging. Also, people have posted that the heater uses more energy than the charger provides. Make sure you fully charge the battery before starting to supercharge. Keep me posted on your results.

    That's what it feels like. The X on the treasure map marks the 110v outlet in some dark corner of the parking ramp.

    Hi CmaxVsPrius:

    The definition of "Pirate Charging":
    Funniest quote I have seen all day. Of course the day is young but it is the funniest so far. :D

    Gary, good find by the way!

    Wayne, you were dead on about the hybrid mode in the C-Max and I was getting far better MPG in my '09 FEH. Rhonda and I just use the C-Max Energi for short trips in EV and try to stay off the highway for those long trips. Basically, the Energi should be used as an EV as much as possible.

    Rhonda's office moved from being 11 miles away to just 5 and she has 2 free level 2 charging stations in her parking lot. We run the A/C all the time and she still drives in antihypermiling mode like always. She kills my Explorer MPG average when she drives it, but she manages to stay in EV in the Energi.

    I took the Energi in for the Sync/MFT updates which wiped out its memory of my driving patterns and battery range. It truly is amazing how the computer learns this stuff and can adjust from the default memory to your driving patterns again and again. I'm not sure if Ford is fed my driving and operation data to some mainframe Ford has too. I can pull up on My Ford Mobil (MFM) on my computer and see where Rhonda is when she goes shopping or anything else like the battery range she has left, charging the battery or when the car is unplugged. I guess this means we no longer have a private life anymore.

    Update - The Energi is still going strong with no problems. I have 3,284 miles, burned ~7 gallons of gas, have a lifetime of 419.2mpg and 117.7mpge. Preconditioning the cabin while plugged-in drops my MPGe, but increases my battery range to 30 miles in EV on average. I have a lifetime 98% regen brake score, so I guess I only used my brake pads 2% of the time during braking.

    That's impressive from an energy conservation standpoint. However, what keeps the rotors from rusting from lack of use, especially in rainy spells?

    The key is not letting the car sit for any long periods of time. My rotors look shinny new because the last 6mph of stopping is pure rotors and pads. In other words, there is no regen below 6mph.

    I just went through a rainy season and I'm good to go with my brakes with no rust on the rotors.

    Just curious, did you put Sta-bil in the tank when you filled it up? I'm having a valve job done on my '05 FEH and the guy doing the head work thinks my valve bent because it seized up from the varnish that is apparent everywhere in my engine. He says he sees that a lot from vehicles that sit for a few months at a time with the 10% ethanol we've had here for the last 20 years. I have parked the FEH during the summers for a month or two at a time so I can't argue with his reasoning. Just wonder how the PHEVs that rarely use the gas engine will hold up in that regard.

    Varnish caused my '09 valve to seize also. Under warranty, they replaced a valve and spring. The Energi has a fresh gas and oil protection system, but the E10 will go bad long before (18 months) the engine burns the bad gas. I'd better put some Sta-bil in it right away. I will never fill the tank again for this reason and only put in 2 or 3 gallons at a time. Wish I could drain the gas I have in it now and use it in my Explorer.

    I've been using a little bit of gas in my CMax Energi. The temperatures over the last several weeks have been pretty darn cold. All of my trips has been short commutes under 40 miles. I can get over 20 miles using my battery pack when the temperature was warmer, now if I use the heater and defrost and the temperature is below zero I get around 13 miles. This still works out pretty good for me. I've had one tank of gas for three months, and I'm just now getting down to the last quarter. I usually can charge my car twice a day; yes, that includes a pirate charge at work.

    Got 105mpg on commute home in freezing temps yesterday. Used my PHEV battery pack most of the trip. Ran defrost and played LoudMusic. Http://pic.twitter.com/dxb8occ37Q

    When my #PHEV CMax Energi decides to warm up it's Gas engine, this is what happens. My 999mpg drops into the 20s.

    Roger, does your Energi need to run the engine to get heat and/or defrost ?
  13. CmaxVsPrius

    CmaxVsPrius Moderator

    No. It has electric elements that work well. I've driven at below zero for whole commutes using them and it gets warm enough. I have it set to EV those times. If I left it on auto hybrid, the engine would come on part of the time.

    But if I crank the defrost to mid or high, and it's freezing out, the gas engine fires up to high idle while driving. No matter of EV setting. Most drive power still comes from the battery at that point. Once the engine starts, it runs for at least a few minutes.

    It will get warmer inside if I use the ICE. And you can get an mpg boost from the big battery pack till it drains. But I like running in full EV mode even at -15 out.

    I can't fault that ; I'd stay in EV as much as I could , too. I guess I really want to know if a PHEV or BEV could work for me , after our recent cold snap. It gets almost as cold here as it does where you live , and I was kinda hoping that I could get warm'n'toasty withoiut burning liquid fuel. As it is , I drive for about seven miles before I even DARE to steal any heat from my ICE. If I could pre-warm an EV before getting in to drive to work , it would be like having my cake and eating it, too.

    Hi Edwin,

    Since you were wondering about BEVs as well, I'll add a comment
    on the Leaf. The heat pump based heater in the 2013 Leaf is one
    of the nicer perks in the winter. Preheat on charger power (at home
    or out and about) can be started on timer or started/stopped
    remotely. The heater will also turn off on its own when the set
    temperature is reached. When unplugged, the remote start heater
    has also been handy on recent zero degree days.

    While on battery power, one can still achieve EPA ratings with frugal
    use of the heater.

    Thanks for the info , Bill ! Sounds like the Leaf will do everything I want it to.

    What have you been getting for range , in cold and in warm weather? Do you charge to 80% or 100% ?

    [sorry; Leaf discussion follows]

    Hi Edwin,

    I have not been pushing the range. My longest trip was about 60 miles
    on 80% charge without running out. On New Year's Day, I did about 54
    miles comfortably with 100% charging. The heater was on most of the
    time for my wife and me. She loves the seat heater, too.

    For this cold weather, I let the battery reach 100%. The computer shows
    86/76 for range (without/with heat running). In warm weather, I tend to
    let the charging reach 80%, or only charge how much I think I've used,
    usually based on a starting charge of 90%. e.g. I drive 10 miles; I charge
    for a couple of hours at 110V with an AC outlet plugin timer. I have not
    installed my level 2 charger yet.


    p.s. 1/14/14 - low 40's today - full charge last
    night and drove 4.1 miles to work. currently
    shows 90/83 for range.

    The Ford Energi models also have preheating and remote start both on and off a plugin.

    The onboard touchscreen has many controls for setting a "go time" temp, be it heating or chilling. You can program in a weekly schedule.

    On a 220v plug, the manual encourages setting a go time temp. It helps the battery because it recieves air from the cabin I think. So a nice steady 70° Could
    bathe the battery pack. On 110v, you can drain the battery some by running the hvac.

    When you use the HVAC while plugged-in, you increase your lifetime KWh and decrease your lifetime MPGe. On a normal city trip, my MPGe has got as high as 191MPGe where my lifetime is only 120.3MPGe now because of all the preconditioning I did last summer. My lifetime MPG is now at 467.1mpg and 3670.7 miles. I've used a total of 7.85 gallons of E10 and 763KWh since new from the factory. I went 3493.8 miles in EV of that 3670.7 total miles, so this means I only traveled 176.9 miles with the ICE running. If you divide 176.9 miles by 7.85 gallons, you get an average of 22.5mpg. A big part of that is cold starts getting to a charger.

    Cabin battery cooling or heating only works with the HVAC on, all other venting the battery is from the outside vent. This means you don't want to use outside venting in real cold or hot weather.

    After driving 800 miles, I decided to put in 4 gallons of gas. That's what you can do when you get 198 mpg. That's my winter average.

    I still have most of my drives being fairly short, under 25 miles. So even in the cold winter temperatures have been able to use very little gas is last two months. I usually get about 15 miles in EV mode when the temperatures are below freezing.
