Sandage - you are definitely going to experience several levels of this low temp chart. Brrrrrrrrrrrrrrrrrr. Here in Niagara Falls we have much milder temperatures (from Weather.Ca).

Hmm.... confirming what I know from my February visits to Ste-Emile-de-Suffolk, ta***nak, c'est froid la!

Although, I see that the 30 year period is 1971-2000, which does not include the warmest 10 years in recorded history here in North America.... I'm guessing statistics would skew notably if they were taken from 1981-2010.

Earlier in the thread, I made the rather naive observation that you, me and MLucas were at similar latitudes... not all that similar temperature-wise, apparently! :shock:

Looks like I don't have the knowledge to create a table... oh well, here are raw figures in degrees C... Potsdam figures from weather.com and US National Weather Service...

Place Dec Avg Low Jan Avg Low Feb Avg Low Dec Min Jan Min Feb Min
St-Anne-Des-Lacs -15 -19 -17 -35 -37 -37
Potsdam -9 -14 -13 -38 -41 -40
Niagara-on-the-Lake -5 -8 -7 -20 -26 -21

Oddly enough, NOTL is the warmest. I know we are in a warmer plant hardiness category of 6a (-10 to -5 F). That is what allows this area to grow certain tender fruits and grapes. Big wine producing area around where I live. Potsdam, NY is Zone 4b (-25 to -20 F). Ste Agetha Des Monts is in Zone 3b ( -35 to -30 degrees F or -34.5 to -37.2 degrees C ). I hate cold weather no matter what, so this only warms my heart a little.

About making a table, I have a program I use called Snag-It that allows me to capture portions of the computer screen and convert it into an image. I can take chunks of websites and blend pieces together and add enhancements. I made the low temp chart using Excel, then turned off the gridlines and captured the chart, leaving behind all the tool and scroll bars. Its the tools that make it easy. :)

You can always make a table in Excel, then click on Print Screen. Paste the results in something like Paint and then crop out what you don't want. That is if you are a PC user. For Apple stuff, I don't have a clue on that - never use that stuff. I'm sure someone in the forum can tell you how.

Re: Cold Weather Chart

Hello All,
Now that the weather has gotten cooler (40F at night 60F day) I have noticed a reduction in range (car stays in a garage at night).

Same driving habits, conditions, heat and A/C usage (don’t use either).

Was getting 5.5 to 6 miles/kW now getting 4.5 to 5 miles/kW.

Is this normal? Do Li-lon batteries have a reduced capacity when cold?

Anyone else notice a drop in range not related to using the heat or A/C?

I'm not in the temperature range of the "cold weather chart" yet so I was not expecting a drop in range.
Thanks!

I should not call it "frette" like in Quebec but this year winter started with the end of october here in the Rhine valley, southern germany.

Driving during day may be fine or not, but at night and charging in the wild can be awfully cold, around freezing and the window keeps fogging.

We used to see ranges of up to 164 kilometers mostly more than 120 kilometers when it was warmer. Now we get between 80 and 120 but below 100 mostly. I guess charging in the cold makes a difference and maybe the state of the 12V battery. I have seen when not fully charged, the display changed up one bar as soon as I turned the key to "ready".

Yes, seeing some reduced range but I'm using the heat and the wind is gustier. I preheat the car using the remote and I also garage the car at night. I usually can make it into Buffalo, NY from Niagara on the Lake, ON on six bars off the power meter during the summer months (43km/27miles). I don't want to say six kilowatts because the power meter is not granualar enough to know exactly how much I'm using. Now its getting colder, I'm usually consuming between 7 and 8 bars off the power meter. My speed is usually about 90km/55mph which is below the posted limit of 100km with only one hill climb and the rest is relatively flat. The temperature has been fairly consistent at 2-3 C/34F (apr). This seems consistent with what I expect for colder temp EV driving.

What you are seeing seems about right for Li-Ion batteries. The battery chemistry slows down in colder weather, thus the reduced power output. The good news is this is not harmful to Li-Ion batteries and they will return to their normal power output when the warmer temperatures return.

Ahhh or should I say Burrrr......
Thanks! The i community is the best!
Makes me feel more comfortable now knowing what to expect.
