hvac effect on range

  1. 3

    Heat off control (like AC off control) or have a temperature range setting

    Having a single temperature setting means that either the heat or AC is on all the time. Being able to set a range where one gets ventilation only without heat or AC would be helpful in temperate conditions, or when the AC is on but the temperature drops in the evening. In the latter case...

    Model Y climate battery usage unusually high (50% battery while driving)

    Hi, I know many parts of the US has been going through a heat wave this past few weeks. I live in the epicenter of the heatwave, here in Phoenix, AZ. I had my 23 Model Y long range awd for about 4 months now. Initially I was getting pretty good efficiency in the spring in my Y, about...

    2023 M3 air conditioner using 70% of energy

    We live in Phoenix, so it is hot, our 2023 M3 standard range at 80% was getting about the range shown 223 miles during the winter. In the summer we are getting less than half of that, we now get less than 100 miles. The energy app shows that all the energy is lost under climate (only occurs...

    My driving range was only 58% of estimated, and 37% for climate control

    So with these new energy graphs I saw how horrible my range has been lately. Of 150 miles of range used, only 87.3 miles or 58% was used towards driving and 56 miles worth or 37% towards climate control. From everything I have read this seems really atypical. Is there anyone else out there...

    Climate (lack of) control

    We've had our MY for just over 2 months and have gone on several road trips already. Love the vehicle, but haven't been able to figure out the climate control. It seems like the rear passenger was rarely comfortable, often super cold. Many times, the vents were not blowing air, regardless if...

    MAJOR breakthrough in HVAC control (heating with single occupant)

    Okay, so I'm an eco nerd and hate the impact that driving in the winter has. I've had my Model 3 through 4 winters now and just today (with the help of the Scan My Tesla app) did I discover that you can go manual temperature control, split the HVAC for left/right controls, set the passenger side...

    Changes to umbilical function

    I'm just noticing a difference in the "umbilical" functions between old and new Teslas. On my Model S, when the car is fully charged and I go to heat up the car, it'll draw power from the charger in order to keep the battery at a full charge. On my Model Y, even though it's on the charger it'll...

    Scan My Tesla results

    I own a 2018 M3 RWD and the following is some information I gathered using SMT. With the car not plugged and the ambient temp around 48F the car draws 3.5KW to heat the traction battery and about 7KW max to heat the cabin for a max total of 10-11KW. When the car is plugged into my 240V@24A it...

    Heater On Indicator

    Is there any way to tell if the heater (or air conditioner) is actually on and using power. Often, the ambient outside air temperature is sufficient to heat or cool the cabin with fan only without using additional battery to do so. It may be a silly question but how does one tell?

    200 Wh/mile to use heater?

    Since I received my Model 3 about three weeks ago, I have almost never seen anything under 300 Wh/mile. Usual range for me was easily 350-450 Wh/mile. Since it was new I didn't think much of it but eventually realized I had pretty poor range. I noticed a few guys talking about not using their...

    Which Heater Setting is More Efficient?

    Let's assume it is 40F outside and cabin temp is set 70F, would it be more efficient to use recirc with AC-on or fresh air with AC-off. I realize recirc with AC off would be most efficient, but the windows get foggy so recirc basically requires AC, at least if using for any extended amount of...

    70 Degree Weather and the HVAC Effect on Wh/m

    Recently here in Connecticut, the really hot and humid weather has broken and we have had about a week of nice dry weather with AM temps in the high 60's to 70's. Now, every AM, I take a trip in the S to the gym and then go for breakfast. Normally this 12 mile trip at 35 MPH consumes 320 Wh/m...
