We charge our EV6 at home and for the last week it keeps saying “charge interrupted” and stops charging. To restart the charger, we are having to unplug and plug 5 or 6 times to get a full charge.
Charging problem - automatically stops charging at home - "The charging for EV6 failed. Please check vehicle"

That's not a good thing imo. The Shell cable is crazy think and for someone that uses the portable charger a lot, because I mainly plug in at work, it becomes unwieldy and a pain to roll back up and put away.the cable is crazy thick.

I means its not a portable charger so its not really an issue for me. Cables got to be thick to handle the amperage.

Ok.. did a completely uncontrolled, vaguely scientific experiment on our EV6.
Some background: We were getting interrupted charging once summer hit at around 11kw in our ~80F garage. Had no issues when we first got the car charging at this rate and in cooler ambient temps. I bumped the charging rate in the car down to 'reduced' and this seemed to fix the issue. I have charged Tesla's/etc. with no issues with our home charger, so I don't think it's the charger.
So.. today, I plugged it in and selected max charging rate in the car. I put a box fan on the plug/handle area. The garage was about ~80F. Voila`.. it charged with no issues at roughly 11kw. My guess is the plug temp sensors? The battery cooling fan kicked on high a few times, and I heard the ICC cooling running the whole time. Just trying to troubleshoot this a bit before we take it in the the dealer.

No fix yet. I sent Kia an email stating that we have a forum with 323 posts so this is a major issue. Honestly it is cool to get a response from a big company like Kia. Here is the response:
"I have not been told of a fix yet. But all issues are being reviewed. Kia will advise customers when a Fix is available. We do apologize for all inconvenience you are experiencing. Thank you."
"I have not been told of a fix yet. But all issues are being reviewed. Kia will advise customers when a Fix is available. We do apologize for all inconvenience you are experiencing. Thank you."
It feels a bit of a standard response though. Did they actually react to our particular issue?
How strange an event you have recorded. I have an exact looking charge event and this is my first charge on my GTL AWD from 22% to 100%.
That happens all the time, to all of us. I have a friend who owns 4 Bolts, and he says those do the same. The Bolt forums think it is a safety check to make sure the battery isn't getting too warm. It could also be a cell leveling cycle.
Not sure how many of you with charging issues have knowledge on best practices of these types of batteries. I can not just write LiFEPO4 as it appears that automotive is using some Ni, Cd, Mg and many other elements to make up these rechargeable batteries.
Its not different then what you surely heard about charging any mobile phone device or electric shaver, anything that is rechargeable. You get it ready to charge, and you leave it charging until the charge cycle is done, and remove it from charging as soon as you can. These batteries today are not supposed to have a memory of charging if you put it on at 20% and then think, oh, I need to use my device and remove it from charging at 30%.. then you are done using the device and back to the charger, 10 minutes later I need to use my device again and remove it from the charger and use it down to the 20% that was earlier, and back to the charger.. these are not good practices of charging. These will effect the battery in the way the heat is going into the battery charging, and the way the heat is leaving the battery being used.
You must have a habit of a cycle that works for the battery, and your environment you live in. If you are doing the 20% / 80% / 20% charging and you have a level 2 charger at home, you know you need to allocate 4-5 hours of charging time that is uninterrupted. Start the charge, finish the charge, remove the charging handle. This is the life of your car and its components. We are not at technology yet that is plug, charge 15 minutes, drive 45 minutes, plug, charge 15 minutes, drive 45 minutes. That is not good for the battery no matter what the factory puts out as an advertisement. They dont really expect you to do that, but it sounds good on paper and sells cars.

I was having the same charging issue so I scheduled an appointment with my local dealership. They told me to try using their level 2 charger and see if the issue still remain. So I charged at the dealership for almost 2 hours and didn’t seem to stop the charging which is good. However, they would’ve charged me $165 if I insisted to have them inspect on the battery which I don’t think is reasonable. I thought this is also included in the 10 years warranty or I might be wrong.
Yeah, I don’t know why they would charge you. It should be part of the warranty stuff. Also - are you sure it’s a L2 AC and not just like a 50kwh DC charger? That’s what my local dealers have.

They dont charge the diagnostics fee if it turns out you have a real warranty issue, the fee is just to weed out folks that would waste their time. Its to make sure you are showing up with a real issue before they have a tech start looking into it, those guys have to get paid for their time spent on your car and Kia doesn't give them anything if no warranty claim is filed.

HERE IS AN UPDATE ON OUR EV6 CHARGING....
NOW THE THE TEMPERATURE DROPS WE HAVE DIFFERENT RESULTS.
PRIOR I REPORTED THAT WITH TEMPS AT OVER 80 IN THE GARAGE, WE COULD NOT CHARGE UNLESS WE SET THE EV6 AT MINIMUM CHARGE RATE 50% AND USED A SEPARATE FAN UNDER THE CAR. THIS CHARGED FOR MAYBE 9 HOURS AT 20A (WE'RE USING A MUSTART 40A CHARGER)
SOMETIMES AT MEDIUM CHARGE RATE 32A AND 75-80 DEGREES WE COULD GET A CHARGE WITH THE EXTERNAL COOLING FAN.
NOW IT IS BACK TO 72 IN THE GARAGE, WE'RE CHARGING AT MEDIUM CHARGE RATE, 32A, AND GOT 53KW CHARGING FOR 7 HOURS - NO INTERRUPTIONS.
SO GIVEN THE NUMBER OF TESTS I WOULD SAY THIS EV6 IS HEAT SENSITIVE (THE INTERNAL COOLING FAN IS WORKING AND WE HAD THE CAR INSPECTED BY THE LOCAL DEALER SAID THAT NOTHING WAS WRONG.
STILL LOOKS LIKE TO US THAT THE CHARGING TEMPERATURE IS TOO SENSITIVE. ANYONE IS GOING TO HAVE TO CHARGE IN THE RANGE OF 70-80 DEGREES - EITHER AT HOME OR CHARGING STATION. IF YOU CAN'T CHARGE AT 40A WITHOUT AN INTERRUPTION THAT'S NOT GOOD.

I have the same charger and have never had an issue with the car set to “reduced”. The display on the unit shows how much current the car is pulling. Set the car to reduced before you plug in.Issue with others at home charging. Took it to local Stafford Kia dealer and it charged fine there and they said they don't know why. I have this cable below. Any other cables people have that are working? Thanks 🙏
Lectron NEMA 14-50 Level 2 EV Charger - 240V 40 Amp with 15 ft Extension Cord & J1772 Cable - for J1772 Evs
When it is below 85F in my garage I can charge at 40A, 9.2kW. Above 85F, I have to set the AC charging current to "Reduced" which results in a 8.3kW charging rate in order to not have charging stop and get the charging failed message via the Kia Access app. Others have reported that the overheating is due to a temperature sensor in the charging port. I have not tried to put a fan blowing on the port area or a wet towel wrapped around the handle to act as a heat sync. Kia Customer Service instructed me to take it into the dealer and mention the temp sensors in the charging port possibly being the issue.

WE ALSO CONTACTED KIA SUPPORT FOR THIS ISSUE AND THEY ASKED US TO GO BACK TO THE DEALER AGAIN. WE'RE YET TO DO THAT. FROM YOUR RESPONSE IT SOUNDS LIKE THEY'RE ACKNOWLEDGING THE PROBLEM, THAT PROGRESS.
SEE MY LATEST STATUS POST FROM TODAY ON THIS ISSUE. NOW THAT THE TEMPERATURE IS DROPPING WE GET DIFFERENT RESULTS AND ARE ABLE TO CHARGE AT A HIGHER RATE.
Thanks for your updates. Also, are you aware your caps lock is on?

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?
