Its because the charger has a max of 40 amps, and the EV6 is trying to pull 48, causing the charger to shut down for protection. It's happened to me too, and many others.

Sorry, wrong. The charger is not shutting down in most of these cases, it's the car. Myself and several others have hardwired 60amp L2 chargers and this is still an issue with our EV6. My charger has charged several other makes/models, and at higher amp settings for charging. The charger and those cars had no issues. I did an somewhat non-scientific experiment a month ago where I put a box fan on the plug/chargeport area of our EV6 while doing max charge, and it worked just fine. If you read back to earlier in this thread, it seems that others have had the chargeport and associated cables changed out and this fixed the issue. I'm hoping they can narrow to just a temp sensor issue or the like and not have to replace the whole shebang. Emailing Kia customer service just resulted in a 'take it to a dealer' reply email.

Now that we're getting some cooler temperatures in my area, I can say that in my case scheduled charging is abruptly ending even when the outdoor ambient temperature is 50 degrees and even when already set to "Reduced" AC Current.

Had a successful charge at "Reduced" setting Sunday AM for 3 hours and 45 minutes; thought perhaps the cooler temps did the trick but then Monday AM had a charge stop after 95 minutes. The Chargepoint App claimed it was "Complete". Had to remove and reinsert the plug to restart the charge to pick up the other two hours of remaining charging.

That's a different issue. Those of us using plug in chargers are shutting down because the car is trying to pull more amps than what the car is rated for. This is why we can only charge on reduced or minimum. Charger can only do a max of 40 amps, and the car tries to pull 48, so the charger shuts down to protect itself. It seems the car isn't speaking correctly to the EVSE.

Ahhh.. sorry then, I just didn't want your comment to muddy the water in relation to the main issue being discussed in this thread. So it would seem the EV6s (some at least) have another issue possibly? Have you tried plugging into a 50amp L2 charger and see what happens?

What really needs to happen is everyone with a charging issue post the software and firmware dates. These issues have got to be tried to software as everyone should have the same hardware for 2022.

Its so strange to me that I have November 2021 software in a May 2022 built car. I am not changing it until there is some really good reason to, or the car ends up at the dealer for service on the battery. I am not going for NAV or AMP updates, and I hope I never get any OTA updates. My GTL AWD has been charged 5 times now and only once to 100%. I am very consistent with 20% 80% ratio. 30 days ownership today and 600 miles. Knock on wood, zero issues and a smile every mile.

 

[Jason G]

You can't. Non-hardwired chargers can only go up to 40 amps.

 

[MikeV]

So the “reduced” charge setting worked for two weeks and now last night the car stopped charging after two hours even on that setting

Outdoor ambient temperature cannot be the only explanation as it was a 60 degree evening. There’s only one lower setting left - what’s a person supposed to do when that stops working, too?

Like you, the same happened with my car. Temps in my garage were in the low 80s (were in the 90s when it previously failed) and it still failed even when the car was set to "Reduced". Next I tried blowing a fan on the charging port and that seemed to work. I thought why not try setting it back to "Maximum" with the fan but it failed within 10 minutes of starting.

 

[sovereign2552]

Don't know if it was said yet. But go to your setup and then click the ev symbol then go to charging current and put it at reduced. Lvl 2 chargers at best can't pull more then 40amps. The cars pulls roughly 42-45 amps at initial charge. Thus you have to change the parameter on the car to not pull max ampere. This does not effect charge time.

 

[Jason G]

This does not effect charge time.

This absolutely affects the charge time. It lowers how many KW its charging. Max will charge at around 9KW, Reduced at around 7KW, and minimum will charge at around 5KW.

I does change the charging time because the car requests less power. In the Maximum setting my car charged at 9.2kW and Reduced it is 8.4kW. Previously on multiple charges it pulled the 9.2kW load and successfully charged. Even when set to Reduced it has failed.

As quiet as this thread has been, is everyone else just humming along fine with the "Reduced" AC Current setting? Because this situation has gone from bad to worse for me.

Waited three weeks to get into the nearest Kia Dealership. Long story short, when we arrived to drop off the car, only then did they inform us that in order for warranty to cover the appointment - they'd have to try and replicate the issue on site but they didn't have a Level 2 charger to do so. Their plan was to run diagnostics on the car, likely tell us it said nothing was wrong and send us home almost $200 poorer and no better off. I've got an email in to Kia support for further assistance.

In the meantime, I decided to do some tests during the day so I could monitor the car (our charges are normally scheduled between midnight at 6am for off-peak rates). I am now 100% confident the issue is the car and not the Chargepoint Home Flex. Wasn't getting any kind of software notifications from either the car or the charger until today - so was hard to say where the issue was for sure. But now I can see that the car is terminating the charge while the charger keeps trying to provide power for an additional fifteen minutes until it sends a notification saying "We wanted to let you know that your vehicle, which is charging at CP HOME, is drawing very little power."

Trial went as follows:

- Scheduled charge for 7:30am, set AC Current to Maximum to ensure the issue occurred. Charge ran at 11kW. Forty-five Minutes later, car stops and says, "Charging Interrupted". This is the shortest amount of time it's ever charged; when the issue initially began it would have at least run for twice that. Car's in an uninsulated garage, outdoor ambient temperature was only 54 degrees.

- Powered on the car, which triggered charging to commence again. Ten minutes later while the vehicle still running, charging stops, car says "Charging Interrupted" and dashboard shows "check vehicle electrical system". That error did not show up in the App which still reports "No Issues Found". Error hasn't appeared again.

- Start the charge again, five minutes later stops again. Worth noting that each time charging begins, the car flaps its front vents and runs the fan for a minute presumably to confirm they are in working order. But at no time during charging did the car ever engage the fans or vents.

- Gave the car a twenty-minute breather, then started the charge again. It stopped again after twenty-five minutes, Charging Unsuccessful.

- At this time I changed the AC Current to "Reduced". Car charged for another forty-five minutes at 9.9kW before stopping. Charging Unsuccessful. Left it at that and will just let it charge more tonight when it's cheaper to do so.

- Along the way I noticed the Chargepoint Home Flex would continue to provide power to the car should it want it. I left it alone for ten minutes after the last failed charge just to see what would happen. After fifteen minutes, I received an email notification from Chargepoint saying the car must be done because its not taking any more power.

I think it's obvious at this point that if the issue were the charger, the charger would not still be running after the car stopped charging, and the charger would likely be flashing red instead of pulsing blue. Now my challenge is finding a Kia Dealership with a Level 2 charger that's pushing 9kW+ of power if they insist on replicating the issue in their service center...

No, I’m still having the issue on anything L2 above 9.6kwh. My dealer did some kind of BMS update and is waiting for a new wiring harness to arrive from Kia.

Thanks - did they insist on replicating the issue in their shop before assisting you? When you say wiring harness, is that the same cabling from the charge port to the battery as seen here #226 or something else?

This was my second attempt at getting the issue looked at, so maybe they just pushed on Techline, I’m not sure. I did give them screenshots of these and the Ioniq5 forums to try to prove I’m not alone in the issue.

In regards to the harness, honestly not sure. The SA called it a wiring harness and that’s what my work order notes say.

Gotcha thanks, appreciate the reply!

I'll let you know what the harness looks like when/if it actually comes in.

Also - the BMS update does not seem to have changed anything for me.

 

[MikeV]

AC "Reduced" setting was working until recently and now that too has failed after 45-60 minutes of charging. The garage was only 73F so not 86F like when it previously kept failing. When charging fails the Wallbox Pulsar Plus sends a message that the charging session has completed and the Kia Access app states "The charging for My EV6 failed. Please check your vehicle." I have tried multiple times to set it back to "Maximum" with and without a fan blowing on the charging port and it fails every time.

Wallbox support has run diagnostics and it is not their unit. Kia Support said take it to a dealership and then call Kia Support to tell them the dealership details so they can contact them.

Have to ask again, did your dealership have a 40-48 amp Level 2 charger on site to replicate the issue, and if not how did they determine they should order a ‘wiring harness’ replacement? Because I’m stuck in a catch 22 with Kia.

I now have a new appointment scheduled at a different dealership - another four weeks out. Kia is telling me the issue will have to be replicated at a dealership, but has no answer for me when I try to explain there doesn’t appear to be a Kia dealership anywhere near me who has operational Level 2 chargers that charge faster than 6.5kW - which is what the dealership I’m supposed to take the car to in four weeks has (they’re public chargers on the corner of their building). The car’s going to charge fine at 6.5kW, as it did last night.

I don’t think so, my dealer only has a L3 charger as far as I know. They did not ask me to replicate the issue for them.

Going to have to work a warranty claim in ours. Problem getting more pervasive. Now occurs everytime we charge. Sometimes stops charging 8-10 different times during a four or five hour session.
