My first winter in NE w/ my 2012 Leaf

Sat Oct 13, 2012 6:24 am

Tips? I'm only just beginning to explore the mysteries of the heating system. I just shortened my commute to about 40 miles RT so I don't think I'll have any issues with using the heater during my morning and evening drive. So the problems I'm beginning to see are the issues around the defrost settings and the way the auto climate control mode work. I've read some of the complex posts about how the mode and auto features work, but to be honest, I still don't think I understand it all. I've figured out the simple aspect of pre-warming the car at a set time in the morning so that's ok, but is there any way to ever get a real blast of heat when your fingers are cold? Does it ever get 'really' hot (if you want to waste the energy)?

Any all thoughts/ideas/help are appreciated.

Thanks,
Jon

The steering wheel heater and seat heaters use a fraction of the power that CC uses and you are already doing the pre heat so you should be good to go.

I have done 65 miles on some rather cold days, so 40 miles should be easy. There is also the old school method of cracking the drivers window open 1/4 inch to keep the fog off the windshield.

Do you park inside a garage or outdoors ?

defrost usage is a major deal for me as well (we AVERAGE 100% humidity EVERY morning in Winter... so ya, we get fog) but defrost introduces cold air and is a power hog so i usually toggle it on and off as needed. for most Winter days, i can get away with this since our weather is relatively moderate despite our northern lattitude

in the morning because i am coming from a much warmer garage, the heat need is much smaller. i am almost always fresh out of a hot shower (i change my routine during Winter to where the shower is the last thing before i get out the door)

however, the afternoon when the car has been sitting outside all day, the heat need is pretty much required. i have played with the settings and found that cranking the temp control to 90 and slowly building up fan speed works well for me. i dont usually have an extreme need for heat and the typical temps are upper 30's low 40's during late winter afternoons (it is pitch dark by 4:30 here after the time change)

Thanks for the reply, I do have a garage, but that is relegated to the wife's car so the Leaf is outdoors. I do use the seat and steering wheel heater ('tho the steering wheel heater shuts off after a short while and I have to toggle it on/off as it must have a thermal switch to prevent burning it out)

You might want to renegotiate that deal: parking the Leaf inside will help with a couple of things:
1) charging efficiency (not to mention bad weather protection)
2) pre-heating in the morning helps a LOT, even in moderate climates like I live in

Again, you can't do much about the afternoon return trip home (sometimes a sunny afternoon helps back off the heat a bit), but you can do a LOT about the overnight charging efficiency and pre-heat by keeping it in the garage.

lower ambient temps will lower your pack's ability to take a charge. i would consider a switch.

The steering wheel heater does have a thermostat and will cycle on and off. If you wait a bit it will come back on as it cools; no need to toggle the on/off switch. If that isn't enough I suggest driving gloves, but I find it plenty warm enough in my car and consider the steering wheel heater a delight.

In reply to the "does it ever get really hot (if you want to waste the energy)", I would answer YES.

Even my 85+ y.o. Mom (who tends to be cold easily) is kept quite comfortably warm once the heat has built up. It does take some power (huge understatement). I concur with those who set it at 90 and use lower fan speeds. If I have a short distance (35 miles rt), I don't worry about using the heat if I start cold.

I park in a driveway, no garage available, and preheating generally gives me about 20 good minutes of travel before I get cold (here in NC, where a "cold" morning is 22 degrees and a "frigid" morning is 15). I've also been known to toss a throw blanket/fleece in the car and put it around my legs in the winter.

I'm anticipating how my LEAF (2012) will keep me warm this winter, as well, and in particular, how well it will get me back home from work (will pre-heat each morning). In the Kansas City area, we get most of our snow in January and the temps can stay pretty frigid (single digits to 30s). I only intermittently get a covered parking spot and will face some frost and snow removal. My commute is ~8 miles one way (~17 RT), nearly all highway, one minor elevation change (uphill sloping bridge over the Missouri river). How do snowy, slippery drives affect range & energy consumption, with or without using heat? I charge to 80% and currently use ~2 bars on the first leg of my commute. On this short drive, should I worry about range on the home trip in snowy weather? I should have ~8 battery bars, but with limited BEV experience and my first winter, I'm a little concerned. Are there any LEAF snow bunnies who can share their winter experience and comment (dgpcolorado?)?

There isn't any situation that you won't be able to drive 17 miles in the next many, many years. I wouldn't even think about it; just preheat for comfort (not to save power, since you'll have plenty).
