Cold sucks (literally)

Fri Nov 08, 2019 6:05 am

I use about 69% more battery when I am driving at temperatures around freezing than when I am driving at 60 degrees f. Does this seem unusual? I park my car outside and preheat before I leave. I also do mainly highway driving. The cold is sucking the life out of my battery. 2019 leaf s here. I can't even charge it enough overnight from a trickle charge to do my commute now.

Nope.

"69% more" is high in my mind, but you are parking outside so the battery end up being cold soaked. Preheating the interior doesn't help that. So the trickle charger doesn't supply enough energy to run the preheater, so you are actually using up some battery power while doing that.

Use heat seating and hand gloves to reduce cabin heating
Install L2 if you can. The charging problem you are running into is that L1 supplies ~ 1.1 - 1.2 kW to the car while pre-heating can use up to 5 kW. Perhaps more if the defroster is blasting although I am not sure about that point.

Even if you only had lowly 12 amp level 2 charging you can get at least 50 miles of range if you only leave the car parked for 7 hours.

A 69% reduction does seem rather extreme, I could see 69% of your summer range(31% reduction) but even in the single digits, driving through several inches of snow and a strong blizzard headwind, I only saw about a 50% reduction in my range(from a normal 70 miles to what I'd estimate a 35 mile range with a 24kWh Leaf.
Even in stop and go traffic where you'd use more heat due to a longer commute, you should come out about the same as with such slow driving your Leaf should be more efficient than going 70mph for the same distance.
Don't get me wrong, you'll see a reduction in range but anything more than 50% just doesn't make sense :?

Coloradoman needs to update his profile signature to show what he drives. Or at least tell us! I suspect it's a Leaf with resistance heat only - an S or a Gen I Leaf, or 2018+ SV without the All Weather Package that was sold where it shouldn't have been sold.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

I haven't had that kind of impact at all around freezing temps. We had a few cold mornings so far this fall in the mid 20's and I park outside. The heater appears to drop my efficiency from around 4 miles per kWh to about 3.5. That's with the heater on, seats on and steering wheel on. What is that, about 13% drop in efficiency?

I DO have the all weather package on my 2018.

If you notice in my original post I mentioned a 2019 leaf s. It has a resistance heater.

I mentioned I use 69% more power. When I left this morning it said I had 77 miles of range. When I arrived from my 27.5 mile commute it said I have 31 miles of range left, just barely enough to make it back home. The 19 more miles used than what was predicted represents a 69% more that what it should have been.
