Just be aware in the user manual it says to not run the seat cooling with out the cabin cooling on

Thanks. I had not noticed that. I wonder why not. All I can think of is that the fan might need cooled air to prevent its motor overheating.

I would guess that the heat extracted from the seat has to go somewhere. If it just exits into the cabin it's not going to contribute to overall cooling much I'd have thought.

I live in Toowoomba which is on the range some 600M to 700M above sea level. I have never had range anxiety in the Kona Electric. This was the reason that I was drawn to this EV with a 64KWH battery. Regenerative braking plays a big part when driving with an electric vehicle. A real world example is travel 50KM down to Crowley vale uses only 4.8KWH because of regenerative braking. The return 50KM trip up the range using the same route and driving speeds requires 10KWH. One needs to factor in the energy use when returning. It is not a problem because the Queensland electric highway has a fast charge station at the university outside of Gatton.
The aircon in the Kona is very good, which is needed in Queensland. The energy it uses depends to a degree on the setting and the driver only setting is handy. My observation seems to indicate the AC reduces distance range 10 to 15 percent.
One benefit of living on a hill one can generate great efficiency at times. Please see screenshot from Hyundai autolink

I would think it would be more to do with the minimum amount of cooling that the aircon compressor could supply, and the seat cooler fans probably pulls cold air from the main cabin aircon and with out cabin fan on not enough may cause it to freeze up.

As EV enthusiasts, we all know or have experienced how fantastic regenerative breaking can be in providing free charging for our cars. It's always good to know that while consumption goes up when heading uphill, some of that will be recaptured on the way back down, as we can see from davidEV's post above.

On the way back from Bathurst to Sydney today, I wanted to see how low I could get the consumption over the Blue Mountains.
I reset the trip computer in Blackheath, and took the picture below in Penrith, just under 55 kms distance, and approximately 1020 metres drop in elevation.
Average speed of 60kph, outside temp was 19 degrees at the start, and up to 30 degrees at the end. Aircon used for about 20 kms.
I was expecting 5 kWh/100kms, so this result was very surprising, and no hypermiling!

I would love to hear of others experience.

How low can you go? :D

I have not done this trip in our Kona but in our previous Holden Volt, we left Leura nominally fully charged with an EV range of about 65km showing which climbed to 114 and regen remained strong all the way down. At the bottom of the mountains we turned right and got almost to the southern highlands on our way back to Canberra before the petrol engine came on. The most interesting thing about it was that it showed that the Volt really does have quite a lot of headroom above the nominally full charge that can absorb regen. In order to maximise battery life, the Volt uses the middle 10.5kWh out of a 16.5kWh battery. It never charges all the way to really full and it never discharges completely. Instead it reaches a set minimum at which point the petrol generator turns on.

Last time I bother you with numbers...
After 6 months and 20'142km on my Kona Highlander, here are my findings.
My average consumption from new is at 12.5kWh/100km.
I drove and average of 110km/day at an average speed of 48km/h.
I hardly ever used the car heating
I used the seat warmer 5 to 10 minutes most winter mornings.
But I do use and abuse the aircon in the full car set between 23-24°C plus seat cooling most of the time the outside temp is above 24°C.
As mentioned before, the heating does make a big difference to the consumption but the cooling has very minimal impact.
As for the driving style, speed and outside temperature are the 2 biggest factors.
I tested something different each month from Eco to Sport and regen 1 only to regen 3 only, and the consumption variations have been negligible.
Even reasonably strong and frequent accelerations made very little difference.
So in conclusion, 400km on the highway and 550km in the city if travelling mostly during peak-hour is perfectly achievable.
A great and mighty efficient car that will be hard to beat.
Oh and thanks to the number of free chargers out there (Melbourne and surroundings), I'm currently at a total cost of charge of $54.56
And that is my total cost of ownership as I have chosen to service at 30'000km instead of the ridiculous 15'000km interval.
Cheers,
Patrick

I want one. My wife would let me buy an E Niro tomorrow because we already own a reliable KIA and I thought that would happen in Jan/Feb. I guess I will be replacing the leaf battery with something.

The e-Niro would have been my first choice had they not postpone the Australian launch.
So I decided to re-ask the question about the potential launch date, well, not a very encouraging reply I received today (19 March 2020)...

My sympathies brunohill. I waited a year for the e-Niro to be launched at the 2020 Aus Open Tennis, only to be told it might not get here until 2021.
I figured that it would be a 3yr old design by then.

Anyway, my new Kona Highlander arrives this morning. I'm gonna head out and have some fun with that.

Have to agree with this. 400km highway and 500km + city
Drove to Ballarat and back on the weekend 390km and would have done it on one charge. Put some charge in it overnight at Ballarat but it was not needed. Averaged 15.5kwh/100km

Drove from Canberra to Narooma on the NSW south coast today on our first try towing a Jayco Flite camper trailer with a Kona electric. 225km and arrived with 95km range remaining, so 320km range, down from over 400km normally without a trailer. I drove at 90kph when the limit was 100. Otherwise up to the limit. I drove a bit slower than I would normally for this twisty, hilly road but not by much. 20kWh/100km.

Great read, Pete! What was the process of getting the tow-bar fitted like? I wouldn't mind fitting one to the Ioniq when it arrives, mainly so I can tow a race bike to the track, sort of thing.

The tow-bar fitting was straight-forward. The fitting place had fitted several petrol Konas and just checked underneath that the relevant area was the same on the electric Kona before I booked it in.
I have written a longer article about it and it has just been published in The Driven. They are OK with it if the AEVA newsletter wants to reprint it too.

Overall from 650m to the coast and back home so no net change of altitude, the Kona towing a camper trailer used 22kWh/100km. Range dropped from over 400km to just under 300km. The route was hilly, twisty and I gave myself a speed limit of 90kph and drove at that speed on the bits that I would normally do at 100kph. Other bits are slower with or without a trailer.

Enjoying the spreadsheet data and posts of range.

Waiting on my Kona EV purchase (bring on Nov/Dec 2020!), and since I don't have a manual to check yet, is there anyway to download/extract the data from the car? Or is it all manual data entry?

Hi Lorax,
I’m excited by your excitement. As you can see from my signature, I’m a few days from 1 year of happy ownership.
And I still smile every time I get in. I should also remember to smile every time I pass a petrol station. My wife asked me about the current price of unleaded a few days ago and I couldn’t answer :D
As far as I know all collected data is manual. It is for me. But there are some serious wizard on this forum. They may have a solution via the OBD port?
Keep an eye for my 1 year post. It should please the nerd in a few (possibly more than a few) of us.

Thanks Patrick.

We're looking at this as a possible option https://shop.openenergymonitor.com/ovms/ but not sure of its compatibility with the Kona or if anyone has had any experience using something like this. I love the data, but the other half is the control system engineer - planning the whole home solar charging control system package (only 2 months and 22 days left until it needs to be operational :lol: ). Soon our home will be producing precious metals :roll: . Geek heaven!

The warm weather is slowly coming back to Melbourne, and with it the amazing Kona efficiency...
11.1kWh/100km on a 141km day of about 70/30 city/tollway cycle. Photo taken late in the evening but the day was around 22-24degC I think.
Driving gently but to the speed limits.

Just a couple of numbers to add

24/10/2019 - 07368km - 100% GOM = 549km @ 26deg
27/01/2020 - 14857km - 100% GOM = 556km @ 31deg
05/10/2020 - 24824km - 100% GOM = 546km @ 25deg

10000km reading 12.5kWh/100km
20000km reading 12.6kWh/100km

I guess that makes it 68 to 70 kWh usable battery capacity at 25 to 31'C.

I think it's 64 kWh useable, and might be as high as 68 kWh in total.
It's not the standard 96s cell arrangement either I believe - more like 98 cells or something odd?

If they re LG63 Ah cells, there's 189 Ah and 358 V, or 67.6 kWh. Possibly more depending on the weather.

Hi Brendon - yes, that's 64kWh 'usable'. When the Kona was in development it was said to have 69 total, however for the released version Hyundai quote it as 67 total.
