New Generation Kona EV

Hi Bruce, here is a real world report which confirms your suspicion. We have had our 2024 Kona for about a week, and have just delivered our 2019 Kona to a family member in another city. So we had two Konas travelling in convoy formation. Distance was 165 km over a combination of two and four lane highways and about 10 km of stop and go traffic through a small town. Both Konas had the Climate system set to "Auto", Driver side only, and 22° Celsius. Ambient temperature was 6° C. Both were set to Level 3 regeneration. My wife drove the 2019 and I drove the new 2024, both with easy normal driving and no high speed bursts or heavy throttle overtaking. Here are the results:

The 2019 started with a 96% SOC and arrived at the 165 km destination with an SOC of 59%. Consumption for the trip was 16.1 kWh/100km.

The 2024 started with a 98% SOC and finished the the same distance with 52% SOC. Consumption was 5.8 kWh/km. (Different default settings, but converts to 17.2 kWh/100km)

So, there is a big (and disappointing) difference, not withstanding any EPA figures.

I would be interested to hear back from others to corroborate (or not) these findings.

 

Were you in front or is your wife just a better driver?

 

A new EV car might not be at its most efficient until fully broken in, after maybe 10K kms. I know new ICE cars don't get their best fuel mileage when new.

 

Agreed, but the reported SoC consumption (46% v's 37%), not so much..

 

I'm thinking a couple of rounds of fully discharging/ fully charging for some extended cell balancing, is what's needed..

 

Thanks for the correction...a good case for proofreading before sending

 

Could be a good point. The 2024 Kona was showing just a bit over 500 km on the odometer.

 

I haven't used it as I don't fast charge on public chargers but can confirm it's a working option on the touch screen.

 

Congratulations on the new car! Keep an eye open for any charging anomalies and let me know if you see it under-charging or drifting downward.

 

Yes, EVs should show battery/coolant temps just like ICE cars show oil and coolant temps.

 

I continue to have this weird charging behaviour where the car will not maintain an 80% charge despite being plugged in at all times. Heck, it sometimes won't even achieve the 80% preset and stops at 79%.

So far it always hits 100% when going for a full charge but, since I don't charge to 100% and leave it sitting for days I can't say whether it would also drift downward from there.

No other owners have reported this so I may be on my own here. I think I'm going to report it to my dealer in a hail Mary attempt at an answer.

 

My Ioniq 6 always says 79% after L2 charging completion. Who cares about 1%?

 

Well, me, I guess...

But it's interesting to hear that it's happened to others. To my mind it's a software issue. I'd just like to see it addressed.

 

But it does not rapidly deplete and stays at 79 until I drive for a while.

 

The apparent 1% drop is explainable in that it’s a truncated 79.99% but not the approx 5% you reported a number of posts back. Is that still happening?
You could try asking on reddit as there quite a few 2024 owners there.

 

It's been plugged in and undriven since Monday. The initial 79% is now 76%.
