Is it wise, @Jan Treur to have your car "preconditioned" to heat up to 19 degrees when starting the car? So the expected range will be more accurate? We don't have anything preset now, it indicates 209 but it didn't even make it from Venlo to Nijmegen and back, driving 100 km/h. (which was about 150 km total). We had to stop at Fastned to make sure we got home although it was 3 degrees outside (warm winter)! Our Imiev/Ion/Zero wouldn't have made that distance anyway but it was more predictable than this car, although we tried driving with all AC/Heat off (which would fog up the front, we'd put in on again, and the range would drop even more). What range do you get these days, and how do you do it?

I will check it tomorrow with temperatures expected not much above 0. What is your efficiency number (kWh/100km) these days? Mine is around 14 to 15 kWh/100km.
I would certainly preheat these days when you leave from home.

5.8 - 6.8 km/kwh->14-17 kWh/100km

What range do you get these days, and how do you do it?

Today with temperatures from -1 to +1 °C a round trip of 92 km, heater on, set on 19 °C, preheated one way, not the return, speed 95 km/h set ACC on highway.

It took 14.3 kWh/100km. Initial range indication with heater on was 200 km for 93% charge, which corresponds to 215 km for 100% charge. After the trip the range indication with heater on was 99 km, and battery charge 45%, so it took more than predicted. Real range for 100% charge with heater on would have been like 200 km.

The heater took all the time between 600 and 700W.

Hey guys,

I am from Montreal too!
I went to an electric car show yesterday where I first heard about the Ioniq!
I was pretty relieved because I thought I would have to buy a Leaf (great car but I hate the froggy look).
My question: Is Montreal winter really hard on that car: battery charge, rust because of salt.... ?
I heard something about sliding/slipping tires on turns, it is true?
It's gonna be my first ev that's why I rather be a little more careful before buying it.
Thanks

Andrew

I'm in Ontario, Canada and I've noticed first hand that my average consumption on BEV is increasing as the temperatures are plummeting toward 0 Celsius. In the summer I used to get 11.2-11.3 kWh/100km, now that is slowly and steadily increasing to around 11.7-11.8 kWh/100km. Factor in its only to get colder and require more heating, its only to continue to climb and climb more when I switch to winter tires.

During last winter, there was a couple week stretch where it was -15c to -25c in the Toronto area. The heater obviously was constantly cycling to keep the cabin comfortable during these temperatures. Range was 150-170km. This can vary more if you make many small trips or just one long continuous trip as the heater will have to re-warm the cabin for many short trips. I plugged in everyday to preheat the car (a feature of the car) before leaving for work in the morning. The range was never a concern for me but depends on your daily travel distance.

I had winter tires on the car and the grip was very good. I actually found the Ioniq to stop better than my gas car due to the regen braking, it felt more confident.

My friend has the new 2018 Leaf and it’s a nice car, looks much better than the first gen. It’s not as efficient as the Ioniq but the bigger battery makes up for it and the range is slightly better. For my friend, they wanted a higher driving position which led them to the Leaf but the Ioniq was also hard to get in Ontario. Maybe the trim and pricing may sway you to one over the other. Both cars are great though

Hello, I live in Montreal, Canada and these last couples of days, outside temperature was around -20c.
The range I can get from the ioniq EV with CCP is around 100-110km with heat at 20c and fan between 2 and 3 bars!!

Usually in summer, I get around 230km

@goncalo, do you park indoors in a heated garage or outside? I just bought a used 2017 Ioniq Electric and park inside (heated). My drive back from Ottawa to Montreal yesterday was disappointing because the indicated range was 208km when I started, but actually barely made 141km with heat at 21C and cruise control at 103km/hr. Outside temp was about -5C.

 

[Ronmontreal]

I wonder if anyone can say with a degree of certainty what the average/ expected range is when comparing winter and summer/ spring driving ? Are outside temperature and the use of AC the two main factors ? Other factors being driving style weather and so on.
The reason i ask is that i have heard many theories but i have not seen real world tests.
There is also a HomePage, egotrip.se that has tried to do this but i am unsure if they are accurate.

I can offer my data over 18 months of summer, fall, winter and spring driving:
Snow tires installed from Dec1st to april 30th . Canadian winter climate
80% of trips 55km or less:

Summer 2.4l/100km, fall 2.5, winter 3.3, spring 2.5

Overall 2.8l/100km
Hope this helps.

So, in %% you can say in the Winter season the Electric Plus uses almost 40% more (37.5%) than in the Summer season.
How much of this was driving All-Electric, like 70%?

If we would translate these numbers in terms of range for the Ioniq EV, you may expect on average 40% less range in the whole Winter season, and of course, this can easily become 50% less range for the extreme days within the Winter season. The good news is that the Spring and Fall seasons differ not so much from the Summer season so that the substantial drop in range occurs only for 25% of the year. Therefore, the annual average usage and range are not very much different from the usage and range in Summer (16%).

Or are your seasons not three months periods? Then the calculation becomes different.

 

[siggesnok]

Just a note on mathematics.. A 37% increase translates to a 27% drop (1 - 1/1.37).

Now we have come to the end of Spring I can compare against Winter here in Perth Australia. Sorry its not directly comparable to those of northern climes, this winter has been especially mild.

Sun hours is not daylight hours its the time in the day the sun was visible to the weather station. i.e. not hiding behind clouds. I track this as part of my solar.

Ranges are all measured between battery top-ups and scaled to what a full battery would give out. These are not GOM figures.

The 403 was 117km over 3 days so not a fluke solo trip down hill and down wind, although my partner drives back from work with the daily see breeze behind. Minimums were trips at Highway speeds.

Now to see how the Australian summer stresses the battery

	Sun Hours	Avg Temp Max/Min		Min Range	Avg Range	Max Range
Winter	6.3​	19.9 / 9.4	C - km	262​	320​	383​
		67.8 / 48.9	F - mi	163​	199​	238​
Spring	9.1​	24.0 / 12.4	C - km	261​	346​	403​
		75.2 / 54.3	F - mi	162​	215​	250​

I've logged every charge ever on my IONIQ BEV and also logged regular odo readings. I use the data to plot consumption and the corresponding theoretical max range. Over the nearly 3 years I've had the vehicle, the seasonal effects on consumption and range are obvious when graphed. I haven't logged temps so I can't factor that into the equation directly. However, I live in Vancouver, Canada which translates to fairly moderate summers (20° C to 25° C) and winters (0° C - 5° C). Below are two plots showing consumption and corresponding estimated max range.

One point of interest: I've noticed that the measured input energy is always about 10% higher than what the vehicle reports was used. Ie, for every 10 kWh metered into the battery, only +/- 9 kWh is ever recovered and reported as used by the vehicle. This I assume, is a measure of the total inefficiency of the system (all the losses due to the EVSE, battery charging process, battery discharging process, BMS, etc). Note, HVAC, lights, wipers, battery warming, etc are included in the vehicle's consumption calculation, so the the 10% difference is not due to those factors.

Very interesting! Your climate is similar to mine, so these figures I guess is what to expect should I change to a second-hand 28 kWh Ioniq. What's your typical HVAC use/settings and speeds?

right. very close to 70% in electric mode about 80% of the time. also correct that the fall and spring seasons are very similar to summer but require engine heating for a few weeks just the same. Winter is the killer on my efficiency with much heating of the cabin and my winter tires with big lugs.

I generally leave the HVAC on "auto" with the temp set to 23°C in the summer and 20°C in the winter. My daily commute is around 100km (round trip) and is mostly on highways. I generally drive 90 kph. Due to the nature of the route and minimal traffic lights, I have pretty high average speeds (usually between 65kph and 70kph). So if your general driving includes more stop and starting resulting in a lower average speed, you might even get better mileage.
