    Just for grins, I charged last night with the 120v evse and connected a Kill-a-Watt meter at the plug and recorded 6.41 kwh to recharge a fully depleted traction battery, with the hybrid portion still showing all blue.

    Charge time on 120v was 4:50; on 240v charge time is 1:50, using Clipper Creek LCS-25, for depleted traction battery.

    EV range shows 30.8.

    Entune app shows 248.64 miles and 466.8 mpg for December so far.

    Best wishes to all for a Great Holiday Season

    How do you get 466.8 mpg when the car shows 199.9 as Max? Does your car display show something lower?

    466.8 mpg is what the Entune app shows as total for the month.

    199.9 is what is shown on the vehicle.

    I suppose the true test is when gasoline is added next, maybe April?, and do mpg calc then.

    Right now, the fuel gauge hasn't dropped from full in the 2 1/2 weeks I've had the Prime.

    i'm amazed at the difference in charge time. 1:50 is incredible for 30 miles.

    actually it's 2.0 hours for 25 miles on the Prime
    :rolleyes:

    i'm going by the o/p's post. there were also discrepancies in pip charging times and ev miles.

    I'm so jealous. I've had to go on a few long trips so I've already filled my prime up 3 times since I got it on the 30th. Averaging 80mpg though over these first 1000 miles so it's still stellar.

    How do you know how much EV range you are getting? I ran the battery down today but when I parked the car, the display only showed mpg. The EV symbol when I start driving right after a charge only is showing like 22.3 miles.

    if it's like the pip, you have to set a trip meter, or i guess you could just use the odo. when the ice fires, you're out of ev.

    Like the distance to empty displays for the fuel tank, I bet the number is based upon past observed efficiency. Drive inefficiently, and the projected range will be less.

    exactly. it's amazing how accurate it is, if you drive the same route all the time. weather becomes the biggest factor.

    Does it just show 30.8 Miles EV Range or can you actually really achieve that ?

    As for the EV range, when we had temperatures in the mid-50s and the heating/AC was turned off, or intermittently turned on, I got 29 to 31 miles EV range. The car pretty much predicted the range accurately. It definitely calculates it based on previous driving. Over the first weeks of having my car the EV range increased every day to around 30 miles...Curious how much it will change when temperatures are in the 70s or 80s (probably will depend on the use of the AC at that point). With the last cold spell here (down to 27), with heater set to 69 - 74, and heated seats on, the predicted EV range is down to 23/24, the real range was more 22.

    Good to hear that range improved over weeks of driving. I've only driven twice now EV and never fully depleted the battery but both times it says I only had about 16-17 miles of EV range before pulling out of the garage fully charged... While driving it the range estimation seemed on point (drove ~12 miles with just under 6 left when I got home) about but that's not too close to the advertised 25 miles. Granted it's hilly in upstate SC but not mountainous and I've gotten no less than an 80/100 Eco driving score nor has the heater had to work very hard.

    the range won't improve unless your commute does, or unless cold weather is currently inhibiting it. but i thought the new battery pre heater was supposed to resolve that.

    In another post, it sounded like the battery heater was a Canada/Alaska/other places with even colder winters feature.

    That was my impression also, that it wasn't for the lower 48 (which is really the lower 49 but who is counting?). It wouldn't have been a horrible feature to get in New England or any part of the upper midwest, but I was under the impression we weren't getting that. I am getting just about 20 miles off a charge with weather being around 17F this week. Last night I did 22 miles and landed at home with .9 miles left on the system. I will be happy to see spring roll around and see what I can really get, but given my normal commute is only 16 miles round trip, 20 miles is more than I need to do my daily driving. Unless I get parking at the office where we have a charger (which would increase my daily round trip to 30 miles) I don't see my commute changing much in the future.

    I have managed to eat into my first tank of gas and have used about 1/8th tank. A few longer drives and one day that was only 11F at 2PM for a peak sort of ate my mileage and required the ICE to warm up the vehicle.

    OM, Page 126,

    Traction Battery Heater.
    When the outside temperature is low and the charging cable is connected to the vehicle, this function automatically warms the hybrid battery (traction battery) until it reaches or exceeds a certain temperature.
    • When the charging cable is removed from the vehicle or remains connected to the vehicle for approximately 3 days, the system automatically stops.
    OM, Page 127:

    Hybrid battery (traction battery) warming control (Alaska and Canada only)
    This control operates after the charging cable remains connected to the vehicle for 3 days and “Traction Battery Heater” automatically stops. It automatically insulates the hybrid battery (traction battery) in extremely low temperatures.

    How do you automatically insulate something? Redeployable foam? Pull a vacuum around it?

    It just means the heater insulates the battery from the cold.
