Re: How much mileage are you getting in this cold weather ?

Thu Sep 11, 2014 9:46 am

I keep the house at 60 sometimes lower so I don't mind cool. as long as the chill is gone I am totally ok.

its 54 miles. 19057 intersection of rt13 and edgely road to 08215 egg harbor city (right on rt30 just before rt50)

over the burlington bristol bridge down jacksonville road to rt206 to rt30

max speed 50mph the entire way. (posted limit) average speed 35mph IIRC) stop and go in the beginning rt13 to the BBB to rt130 once on jackson ville typically 4 or 5 lights the rest of the entire trip to destination so a pretty constant 50mph non stop once on jacksonville

Here is the precise route I take with the start and end points anonymized (within half a mile of each point)

I made it to work this time with 5 miles left BUT I started with a partial charge (said 65 miles) and I took a 10 mile detour (brother missed the bus so I had to go get him) so the meter was pretty darned accurate.

I now have a 100% charge so I will get a better "range" figure when I go home tonight and report that back here.

if it can't make it in dead of winter no big deal. I have plenty of other cars we only get a month or so of "truly" cold weather (ie snow and sub zero deep cold etc..) otherwise reasonable mild 20-30' weather.

An eventual plan is to carry a small genny with me like a honda i series (super quite) with 220v output. enough to get that little extra push if push comes to shove.

for now if I don't think it can make it I just won't use it. will take the minivan or the metro instead. no big deal.

Without knowing the condition of your battery it's hard to say, but I suspect you'll be doing your winter commute in one of your other cars. How many battery capacity bars do you have (the short lines to the right of the longer ones showing state of charge)? 12? Less?

the second skinny line is full (no more "bars" to light up all the way to do the top)

Okay, you've lost less than 15% of your capacity, which is good for a 2012.

I would hope so with only 4800 miles on it.

but "I" will put 30k PLUS on it in the next 12 months. :-)

It's been found that degradation due to calendar losses are almost always greater than those due to mileage, with battery temperature and state of charge being the most critical parameters. Cars that have been sitting on dealer lots for many summer months at 100% charge before selling are often far more degraded than you would infer from their low odometer readings. Be sure to read the wiki for more details: http://electricvehiclewiki.com/Battery_Capacity_Loss" onclick="window.open(this.href);return false;

The best way to tell what's going on with your battery is to get one of the aftermarket OBDII devices and one of the smartphone apps like LEAFSpy.

Well I drove home tonight just shy of 54 miles. I started with roughly 95% charge? Said it needed 1 more hour for 100% said I could go 104 miles this rapidly dropped to 97.

I got home 42 miles left. Nice. Very nice. This was pretty ideal conditions. 71' light traffic no accessory usage except lights and stereo.

Very promising. That is a nice buffer. So the eventual 97m estimate was surprisingly accurate. At least for my commute in optimal conditions. The lost mile or so I guess was the headlights?

With these additional details, I think that there is a pretty good chance that you can make it for several years to come except when it is actively snowing. You will need to get comfortable with using the lower part of the battery pack; there is still plenty of useful charge below "Low Battery Warning". I get similar distances quite easily in winter at those temperatures since I don't need to use the cabin heat (dressing warmly, the norm in winter anyway, and the steering wheel heater are plenty for me most of the time). But some people are adamant that not using the cabin heater during the trip is not an option.

In my view, the things you have going for you are:

• The relatively slow speeds of your commute; there is a huge difference in range at your reported speeds versus blasting along at 65 mph, as so many people do.

• Your comfort at cooler temperatures (I keep my house thermostat at 62º mornings and evenings and 52º at night). If you can do this commute with preheating and skip the cabin heat, it will help the range. Be aware, however, that the 2012 has no heater-off switch. If you need to use the defroster the heater will come on and suck down power. [I don't think they still have it, but EVSEupgrade.com used to have a climate control mod that will allow you to turn the heater off and still be able to blow air on the windshield. It is a big help on my 2012. Another option is a DIY approach: Easy Climate Control Fan-Only Solution - 5 cents, 5 mins.]

A possible problem would be if you park outside at home. If you have an enclosed, attached garage, it should help keep the car and battery warmer (a cold battery has reduced capacity/range). Charging the battery will help warm it up some. At work, the combination of driving to get there and charging while there will also help keep the battery warmed up some. If you park outside or your garage gets below freezing at night, that will reduce your range.

I expect that as the temperature declines you will get a feel for how your range also declines and can decide if you are pressing your luck. Be aware that wind, rain, and snow (of course), can reduce range significantly. If that happens, the way to make the trip is to slow down, since you don't have any enroute charging options.

Some things to consider: what if the workplace charging isn't working or is blocked? What if it starts snowing hard during the day? You aren't getting home in the LEAF!

You need to learn to not rely on the "Guess-o-meter" (GOM). Given that you are going to be pushing the range on a regular basis you need a more precise fuel gauge, such as "LEAF Spy", mentioned by GRA above (if you use an Apple phone I believe that there is another app that will work with that). In addition to giving better fuel information it will also give battery temperature, which will be helpful for you to watch, since it affects battery capacity in the cold. For your purposes, the car fuel bars or GOM is not going to give you the confidence you need to stretch the range.

I have leaf spy. Not sure how to read it. It always shows 20 miles less range than I actually get or I am reading it wrong

Sadly bare cold outside parking only.

I have a backup vehicle at both locations so no worries there.
