Heat Pump Performance - Anything to Report?

[Kamuelaflyer]

I agree. But I’ll go one further… if @Ford Motor Company had actually done this, don’t ya think they would have bragged about it??? Which provides strong evidence to me that they didn’t do it. So there was this speculation in a much older thread about how Ford might have “hidden” the range increase as an emergency reserve below 0% SOC. Which again seems a bit silly.

@Ford Motor Company could always weigh in at any point to resolve this little riddle. Well, Brian, what say you?

Yes, they would. Brian is on days off until the next year.

^^^ Agreed I have been asking how the heat pump sounds in the cold. In hot temps the ac pump is really noisy so wondering if the heat pump is the same in the frigid cold.

2025 premium here - it's noisy in the cold. The noise varies, sometimes loud, sometimes not so much.
It does work great though

Finally someone answered thank you!! Makes sense what I suspected.

Well, one thing is sure, my 2025 Premium cabin heat in very cold weather is much improved vs my previous 2021.

Please define very cold. At some point the heat will come from traditional resistive heat and not the heatpump

I highly doubt the heat pump actually heats the car faster than the regular heater. Based on my experience with every heat pump ever.

-25C I understand the heatpump does not contribute down there, but the car stays nicely warm. Yes it can be noisy when pre-heating the car.

If the controls are anything like a conventional heat pump system, the resistance heater is also on when the difference between the set point and actual temp is more than a certain amount.

In my 21 MME, in the winter my range would go down to 180-200 miles even at 100%. The last few days have been in the 30s and 40s, its 33 degrees at the moment. I'm charging to 100% this morning (in the garage) and I am surprised at the range I am seeing. It would seem that the heat pump is doing quite well!

Not going to happen. Guaranteed not going to happen.

Ford has stated ZIPPO about increased range due to the heat pump in either the Mach-E or Lightning. Therefore, they never will.

In my 21 MME, in the winter my range would go down to 180-200 miles even at 100%. The last few days have been in the 30s and 40s, its 33 degrees at the moment.

This is a non sequitur. Correlation does not imply causation. The GOM could be predicting a higher range due to the temp being higher than when your 21 showed 180-200, due to a change in the GOM algorithm, due to recent driving being the reason the range is higher, or to the all time favorite "shit happens".

My Mach-E is currently showing 219 at 90% for a range of 243. Over the last 200 miles, all local driving, we have achieved an overall average of 1.97 miles per kWh. 1.97 x 91 x 96.5% SOH = 173 miles.

If I use the last 100 miles of driving, efficiency is 2.17. Doing the math, that's 191 miles.

To get 243 miles, I need an efficiency of 2.77. That was last achieved in mid October, 800 miles ago.

If this doesn't show you that the GOM is basically useless, I don't know what does. My guess is that it reacted to Sunday's 50 degree temps when it poured rain, and hasn't yet realized that it's currently 28 degrees outside. I suspect when we start driving later today, it will drop substantially.

Haven’t charged to 100%, but the math for mine after a week of 40s and 50s was low 200s for my 2025 extended range. Was surprise to see that much of a drop off.

In spite of what the label says, the GOM is not your range. Way too many variable to attribute a random number to a single cause.

Styx made a song about it….

Mode is irrelevant.

You don't think that driving on Unbridle vs Whisper Mode uses more of the battery?
Just asking..

I know it does not. Posted very often. It impacts pedal response. So if I feather the pedal in Unbridle, it's like driving in Whisper.

Understood, I guess it does make sense - It's just hard to feather in Unbridle BUT I will give it a try. LOL

Thanks

Energy use (for driving) depends entirely on the motor load. Load depends on acceleration/speed requested by the driver. The only real difference between modes is whether that demand is created more at the start of or at the end of pedal travel. Therefore it's completely at the pleasure of your right foot!
