Range in winter

Hyundai called & said my battery replacement will be here in a couple of weeks.
I'm looking forward to getting it replaced and then I can sell it.
Maybe their ionic platforms will be better.
I need a larger vehicle anyways; the Kona isn't very kid friendly.

 

2019 Kona Ultim
My datapoint - left garage, drove to work, parking in unheaded garage.
On my way home - battery at 80%, heat on, defrosters on, driver seat heater and steering wheel heater on.
Outside temp -18C (-.4F)
EV battery info page reported: Range with climate on: 208km (304km with climate off)
Total trip consumption 30.5kwh / 100

 

Can you estimate the average speed of your datapoint?

A trip at 80 kph versus 120 kph can have a large impact, even at these cold temperatures.

 

I'm curious about what sort of climate settings reduced your projected range by almost 100km?

 

My drive to work was 6.4km downhill and flat (i usually regen 2km on the downhill portion), max of 50 km/h city driving.

 

heat set to 22C, fan turned up, front & back defrost on, driver seat heater & steering wheel heater on.

switching back to auto would regain about 10km range

 

Huh. I've never seen anything that dramatic. Does it recalculate as you drive? I've certainly seem that happen.

 

only recalculating I've seen is if i turn climate off.

Today, drove again from unheated (but not as cold as outdoors) garage to covered but exposed parking garage and then home again, 6.4km each way.
This morning it was -21C and this evening it warmed up to -13C
22C auto heat, heated drivers seat, stearing wheel heat on, winter mode on
SoC down to 60% (from 80% last evening)
range reported on EV Energy Info screen 157km (222km with climate off)
Consumption Info reports my recent average is 32.1kwh/100
driving speed was even slower today due to snow covered city streets.

 

That's really interesting. I don't find huge differences in range between different drivers odd at all. There are so many variables. But your differences between climate and no climate seem really large compared to what I've seen with my car. I usually see a 20-30 km drop at most. I wonder what would cause that?

 

I'll add one more datapoint, then leave it

Last night I charged in the garage, (to 90% because I forgot to reset the max) and this morning I preheated with the Bluelink app.
Today, drove again from unheated (but not as cold as outdoors) garage to covered but exposed parking garage and then home again, 6.4km each way.
This morning was warmer - only -11C - and this evening only -7C.
22C auto heat, this morning did not need heated seat or steering wheel due to preheat, did use both on the drive home
This evening SoC down to 85%, range 276km (335km with climate off)
Average consumption slightly improved to 27.1kwh/100

So slight improvement due to preheat and warmer ambient temps.

 

Hi Julie, we are having the same issues as you and any further updates from Hyundai Canada? We are located like you in Canada and our Winters get cold. With our new battery replacement for the recall R0183, we also noticed a significant range reduction up to 40% as we get around 285 km now. We had to fight to get our $250 for all the inconveniences since Hyundai Canada reduced our range by 80% remotely without our knowledge/permission. Our dealership can't help us and apparently they opened a case with Hyundai Canada but they haven't got back to us yet since they are assuming that our family or other Hyundai Canada owners will forget. They seem to be coordinating their efforts together to Delay, Deny and Deflect to assume their responsibilities from all these Kona EV lemons since we are getting the same error messages. We took photos of all the Kona EV error issues and from their diagnostics, they couldn't find anything while the proof shows the contrary. Transport Canada was no help to help/protect Canadian citizens and we would be interested to start an action like they did on South Korea if other Kona EV owners join us in solidarity!
