    I would assume you use the heater often. California weather in spring we rarely need to use the heater or ac... I also mostly get a 290+ projected range with an average of close to 4.7mi per kwh. However one night I used the heater and the consumption dropped below 4mi/kwh on that trip. Also do you drive alone or with other passengers? I guess overall weight plays a factor too.

    Good evidence that environmental factors make a huge difference in consumption. I wonder if we all experienced much the same in our fossil cars but didn't notice because we didn't have the ready data then.
     
  4. Good point, in a gas car you just don't know.

    We went on a drive today to take the dogs to the beach. 125 miles round-trip. Used the AC nonstop to keep the dogs cool. Range dropped by 25 miles instantly when we turned it on. Used 45% SOC for the trip. 90% to 45% after the trip.

    So 125 miles for 45% SOC. Matched perfectly with what the GOM projected.

    Outside temperature around 27°C (80F).

    Fun tidbit: had a 3 mile decline that charged the battery with 6 miles worth of electrons. Going back up it dropped of course. Still had a round-trip mileage of about 4.8 miles/kwh driving in eco mode with AC on!

  5. Any action from the tms yet? ( displayed as battery conditioning if I recall )
    Just wondering the cut in point.
     
  6. Maybe you're right. I routinely have 100km less estimated range that you're reporting. I do use the heater (19 to 21°C) and the seat heaters most trips. My ambient temps have ranged from -20 to 10°C during the past month so that's very different from both BC and California. Perhaps I'm an outlier mostly due to location. It just seems like such an impossibility that I could expect a 100km + gain in the summer months to come. But I guess we'll see.

  8. Nope, actually I was wondering too and specifically looked into the EV menu for it, but no.
    Question, in the EV menu it shows that the range is xx miles less because of air conditioning. Does it do the same on yours for heating?

  9. Yes indeed, when you shut off the heat you X more km

    Sweet baby Jesus!
    How are folks getting these numbers? I’ve never once even come close to approaching 400km. I’ve charged to 100% twice and saw about 380km each time. I charge to 90% daily and see an average of about 340-360 km depending on the outside temp. I’m in Southern Ontario where average temps have been about 7 degrees Celsius.

  11. Exactly!! Thank you for sharing my pain. Finally. Everybody west of Ontario gets these numbers.

  13. Temp definitely plays a big factor. I think the amount of energy consumed is something like:

    Heater > A/C > Heated seats

    ...with there being a pretty big gap between each of those. At 100% SOC, my car is telling me I have about 290 miles in ECO mode, or about 280 in Normal mode. But I drive pretty conservatively and most of my driving has been with really moderate temps lately, like 50-70 degrees, which I think is optimal for the battery pack.

    I suspect some of the folks getting low numbers will see a very nice increase come spring and summer... Keep us informed.

    Absolutly,
    I certainly hope there's going to be a bump - or to what Wildeyed said (I think in a different sub) I'll definitely be speaking to the dealer.
    I just don't foresee how a few more degrees will magically give me 100 additional km of charge (some of you are seeing over 490km on the GOM) We had a handful of days a couple of weeks back that were 17 degrees Celsius, and I still didn't see anywhere near 400 km at 90% SOC. Should be interesting.
    Does anyone know of a way to "reset" the battery or information? I don't know if this is even possible, but the numbers are so drastically different!
     
  15. There's so much battery baloney flying around out there that it's hard to know, but if you let the battery run down and then recharge to 100% the "brains" should reset to acknowledge the full range of the battery. Remember, all these range numbers are based on driving and charging history so they are not absolute measurements of fullness or emptiness. Thus the "guess-o-meter" name.

  16. I'm pretty sure you can reset everything using the buttons on the right side of the steering wheel. You can reset all the various consumption numbers that you scroll through to the right of center on the dashboard. Like the miles per kW and the % of your driving that is economical vs. normal vs. agressive, etc. Those can all be reset I think.

  17. Driving to 50% SOC from 100% should tell you the actual usable pack capacity (multiply kms *2 @ whatever Wh/km consumption), driving to near zero SOC will tell you if there is an imbalance in the cells ( indicated by an early turtle )

    No everybody out west does not get these numbers, come on Wildeyed!!!
    I drive 150km round trip for work. I would say 100km of it is at speeds over 100km/h, 45km is at or over 70km/h, and 5km is at 60km/h or less. I get around 370-380 on my GOM at 90% charge. I would say I average around 15-16 kwh/100km, without heat. I don't have many stop situations or lights to recuperate energy. After 300km of actual driving I recharge my car (GOM usually says about 50-60km left). I charged my car to 100% yesterday and it only shows a GOM of 410km, again based on my driving pattern. The fact your temperature is colder and you use the heater, seems like a reasonable difference to me.
    One day I did a city drive to run some errands. Very low speeds and lots of lights. I did about 40km and only used 12.7kwh/100km. Now when some of these people in BC are reporting 490+, imagine what kind of driving they do and if they actually go by the GOM, or the actual km they drove. I laugh when people say they drive half highway and half city, but their whole trip was maybe 20km o_O.

  19. I find a simple thing like wet roads can increase consumption considerably, add a headwind even more.

  20. I appreciate the information. Your travel habits are more similar to mine than some other folks. Because I live in the country all of my trips are highway, either 90 or 110 kph with either 100km or 225 km round trips with a wee bit of city once I'm at my destination. I regen the heck out of things as soon as I'm in traffic but that's a small percentage of my travel time. I have yet to break the 400 km recharge level or approach efficiency under 15kwh/100km. We'll see soon ( please God) when real spring weather hits whether weather (?) Is as big a factor as I hope. Maybe +10°, no heater and Summer tires will be the magic formula for success.

    Maybe not a complete magic formula based on the type of driving you do, but higher temperatures means the battery starts off at more ideals. You may never get what other people get.
    On Hyundai's website for the Kona they put this in the legal print for the stated 415km range:
    "^Range calculated based on a fully charged battery. Based on manufacturer testing and used for comparison purposes only. Actual range may vary based on driving conditions and the addition of certain vehicle accessories."

    Here is how Europe does it tests, key point battery is left at 18 degrees Celcius.
    https://insideevs.com/what-car-real-world-range-hyundai-kona-electric/

    Here is an Oct article on range, note the highway range is 226miles (364km) which is close to your type of driving. City drivers might be able to get almost 100km more!!
    https://insideevs.com/hyundai-kona-electric-epa-range-breakdown/

    You have to remember the 415km EPA range is done at certain conditions and temperatures. Here's a few more articles and links to explain how they test:

    It was quite windy in Vancouver yesterday. Approximate guess here, but I bet was close to 10% drop in efficiency due to the wind.
