Winter range

[mateo]

Ha, not one of those.

I got 3.9 mi/kWh on my trip today. No battery pre-conditioning since I don't have L2 charging working. In town, snow, 30 degrees.

I set the temperature to 62 auto, which turned on heated seats and steering wheel. I'm actually uncomfortably hot with the heated seat, so will probably need to turn that off.

I don't take many road trips in the winter, so if I keep this efficiency up, I may end up with a bigger battery by summer. Wait, that's not how it works? ?

The car is great fun!

On Friday it was 68F (38 the night before), and I got 3.8mi/kWh, used 4.7kWh over 17.6 miles.
Today, it was barely 40 (28 over night), I got 2.2mi/kWh, used 7.9kWh.
Both days plugged in with departure times set, etc - no difference other than colder.

I feel like having battery preconditioning would help hugely - no way maintaining cabin temp accounts for that big of a difference in efficiency. A 10 degree colder soaked battery, though, maybe?

A departure time, plugged in, IS preconditioning...

That preconditions the cabin, not the battery, right?

Not right. A departure time does both.

Well, scratch that theory, then. Is it charging that the battery doesn't precondition for?

Still, wonder why the big difference. One of the kids did fart this morning, but the windows were only down for a few minutes.

Also, just stopped myself from going down a rathole comparing efficiency and temperatures. Because it doesn't really matter much.

Correct. The battery does not precondition for charging.

What was the speed? My freeway consumption is around 2.2 too.

I am not using Mach-E this weekend for Detroit-Chicago trip

Don't recall exactly, but it's the same route all the time, about 5 miles of traffic on the highway, and 12 miles of 25-35 mph back roads

The traffic helps big time, I had a 3.7m/kwh through Chicago this summer at 90mph.

If it was 68F, you likely didn't even turn on the heat, or it didn't run much. If it was 40 degrees, you ran the heat. The difference in those drives usage is 7.9 - 4.7 = 3.2kWh. The heater can use 2/3rds of that in 1/2 hour. Then you add in the cold temp lowering your efficiency say 20% by itself. Makes total sense.

90 mph through Chicago?? I was happy if I could drive at 30 there...

3.7 sounds pretty high even for summer

 

[breeves002]

Lol I drove about 72mph in 30ºF 250 miles round trip the other day with a fairly short stop to charge both ways. Like 2.3mi/kWh for me. I keep the heat up at 70ºF though. No complaints I'm fine with that I just have to remember to plug it in more at home in the winter.

On the highway, gotta keep up with traffic . And yes that was a few months ago. My car is a premium AWD extended with CR1 wheels
