Precondition your Mustang Mach-E

MachE_ArtOption_Charging2.jpg


Winter’s just around the corner. We wanted to give you a few tips to maximize your range as the cold sets in. Your Mustang Mach-E was tested in extremely cold conditions. However, all-electric vehicles have less energy in cold temperatures compared to warm due to battery cell chemistry. While you might not experience extreme cold, even temperatures below 40°F can cause the electrolyte fluid to be sluggish, limiting how much power is available to discharge and how fast the vehicle can charge.

To help maximize range in winter, follow these pro tips:

1. Park in a garage wherever possible
2. Keep your vehicle plugged in when possible
3. Precondition your vehicle by scheduling departure times to warm the cabin and the battery while plugged-in (using the FordPass™ App or the SYNC® 4A touchscreen)
4. Use the heated seats and steering wheel as primary heat to reduce energy consumed by HVAC
5. When charging, turn off the heater — especially when using Direct Current Fast Charging (DCFC)
6. If snow covered, brush all the snow off your vehicle before driving to eliminate extra weight and drag
7. Keep driving speeds moderate as high speeds use more energy
8. Make sure your tires are at the proper pressure

Driving habits will be learned by your car over time.

By manually resetting EV driving history, your vehicle will erase all driving behaviors and revert to summer conditions to recalculate projected range, which will be significantly higher than actual range available in cold weather. Intelligent Range will begin to adjust to reflect winter conditions and owner actions, so initial remaining range may drop more quickly than actual miles driven as the newly learned driving conditions are factored in. To reset driver history: click on the vehicle icon in the top left corner of the center touchscreen > Select Settings > Select Vehicle > Select EV Driving History Reset.

These two are news to me... And good to know. We have never been to a DCFC charger (FE delivered in Feb 2021)
4. Use the heated seats and steering wheel as primary heat to reduce energy consumed by HVAC

Also,
if someone has been driving their MachE for a while..
why reset the history?
It should have been learning all along and that ML should have a tighter % deviation than going all the way back to a Summer Baseline to start learning again...

seems like wasteful CPU and Time To Reality (TTR new acronym) .

They are saying that IF you reset the history, you will see the range remaining drop faster than you drive the miles, i.e. youmhave range remaining of 150 miles, drive 20, and have 110 left instead of 130. That's due to the reset defaulting to the summer algorithm, and then rapidly adjusting to the cold weather.

I have a question about “turn off the heater while charging.”

If the car is parked in the garage, and you aren’t in it, will the heater run?

Or is this more about DC charging if you’re sitting in the car?

I wish they would be more specific with instructions.

If you are parked in your garage you are charging on a level 2 charger and your car is not turned on. Therefore the heater is not on. DC charging is the public charging you do at Electrify America or ChargePoint chargers, EV Go etc. For these you are most likely sitting n your waiting on the charge to complete and you might be tempted to run the heater to keep warm if it is winter.

I don't think the "turn the heater off while DC charging) has anything to do with range, but it has everything to do with the length of time you'll be sitting at the charger charging, because the heater will be hitting the battery while you're charging and take that much longer.

You won't leave the charger until you get to 80% (UNLESS @Ford Motor Company ups that to 85% or 90% for winter as promised by Darren Palmer several months ago), so how can running the heater impact range?

Darren had said Ford was aiming for the charge limit and charging speed updates before winter. Winter is still technically a month away but we're getting lots of snow in the Cascades these days.

Right. We're planning a trip mid-December. Just ran the numbers taking our F-150 vs. the Mach-E. If we got 91kwh instead of 88 (3.4% increase) and 90% fast charging instead of 80% (12.5% increase), that's a combined 16.3% increase in range. That could remove a charging stop, or two, on a trip for an insignificant increase in time at the charger.

Right now, our total trip takes 15% longer but saves ~$250 if we take the Mach-E vs. the F-150.

There's actually more to it than just the heater using up some battery power. If the battery is cold, it will charge very slowly. So the heater is used to heat up the battery to accept a faster charge. If you have cabin heat on, less PTC heat is available to warm the battery so that it can reach peak charging speed.

That being said, if you're cold inside the car while charging, run the heat. Taking a bit longer to charge is better than freezing.

I would assume that in driving a few hours before getting to the DC charger, with the heat set on 68, that the battery would be warm. I may be wrong on that.

Depends on how you've been driving and how cold it is outside. For peak charging speed, the battery actually has to be quite hot. That's why some EVs automatically precondition the battery to warm it up en-route when you tell the Nav system that you're going to a DCFC station (like Tesla). Darren Palmer said a while ago that this type of battery preconditioning will come to the Mach-E, but I haven't heard anything about that recently.
