Mine goes to full power straight away on 7kW & 11kW charging. MY22 GT Line S. ICCU update has not arrived in UK yet. I’ve not had any VCMS update either. My moneys on the ICCU update. Strange others have not seen this in the US as far as I know.
Jeff, I have an appointment with Safford on 12 June for ICC recall. If you want, we can meet up somewhere and compare charging on our GT's. Maybe Walmart? I would test mine, except I don't have the apps you have for the readouts
We'd have to meet somewhere there's a high powered level 2 charger to test and compare haha. That said, you should be able to just check when you charge after the update in the gauges if it's at the full rate for the first few minutes.
I recently did the ICCU update. I was in and out of the dealership in less than 45 minutes. I just started charging my car using my at home level 2 charger. No delay/ramping of speed in the charge. It went straight to 9.04 kW which is the normal speed for the charger. I have my AC and DC charging limit both set to 100%.
That's weird, my GT-line doesn't do that and it has all the latest hardware updates. But at home most of the time I keep it set to 60% rate so be as easy as I can with the battery. 2 years old and only 2.6% degradation according to ODB2 via ABRP lice reading.
I had the misfortune to have my ICCU fail in late June during the dealer cyberattack. It was about 3 weeks before they could even order the part, which was backlogged. It took seven and a half weeks to get my car back. Fortunately, Kia America is offering options for compensation, which I definitely appreciate given the frustration of being without my car for so long.
I have a 2023 EV6 Wind AWD. I've noticed in the past that charging speeds ramp up after 1 minute to the maximum my EVSE supports (48 A). I had my ICCU replaced recently and since then I have also seen it ramp back down to about 31 A after a while. That might be related to the ICCU update, or just the unusually hot weather we've had recently. I'll be annoyed if I can't sustain 48 A anymore but if I'm being honest, the slower charge rate is still more than enough for my needs.
I have a 2023 Kia ev6 GT Line Long range AWD. I had the 2 recalls done 2 weeks ago. I charged the car 3 times since, (each time to 100%) and have seen my range increase from 301 miles max to 344 miles max each time. I called KIA and they can't explain why and said that they would check it out but haven't gotten back to me. I did not notice if the first 3 minutes charge at a reduced rate, but I will check it out tonight when I fully charge the vehicle again and I will let you know if this happens to my car. Thanks for the heads up, Jeff
@@TechnicallyJeff Ok, Jeff. I just plugged in 2 minutes ago. I was at 65% and I always charge to 100%. As soon as I plugged in the charge rate went to 11 kwh. as usual. I have an Emporia charger. It is hardwired. The total time that it will take to reach 100% reads 2 hrs 05 mins. Nothing unusual about the procedure. After being fully charged the range should be between 333 and 344 miles. FYI: Kia told me to charge to 100% all the time. There will be no battery degradation. Also, this car is a 3 year lease. I will not purchase an EV vehicle while the battery technology is changing as rapidly as it has. I have 2 years and 3 months left on my lease and I plan on flipping this car for a new one when the lease expires. I do expect the 2026 model to have a range between 500 and 600 miles. I have been leasing cars for the past 55-60 years. There is no need to own something that depreciates as rapidly as an automobile. It works for me. BTW: This is probably one of the best built EVs on the market, if not the best.
Good info. Regarding charging to 100% all the time, I'm not sure who told you that, but that's definitely not ideal. We have lithium ion batteries. Ideally we want to keep them between 40%-80%, with very little depth of charge each time. It's recommended to charge to 100% at least once a month to balance the cells and for BMS calibration, but not every time. That said, in your lease you won't notice a degradation. Just the next owner will lol. And it shouldn't be too significant.
@@TechnicallyJeff I just charged my 2023 KIA ev6 GT-Line Long Range AWD overnight (to 100%) and the range says 370 miles. Did KIA upgrade the software to increase mileage?
@@TechnicallyJeff Just had SC302 installed and no change in charging rates using a ChargePoint from 2017 at 32amps for my 2023 EV6 Wind RWD. They also installed SC311 during the same visit.
I noticed this at the Kroger free charging station. They have 2 and I was speculating on if there was another vehicle charging it was reduced because of their system but came back after shopping 45 mins and was 9.2 kwh still 2 vehicles charging. I was thinking wrong temps but its only 9 kw not 150 kwh and it was 70 degrees and battery not hot or cold so yes Jeff, I experienced the same thing! 23 EV6GT 18k No other issues. I normally charge at home from about 30 to 40% to 60% @ 60% charging rate but when it is free I boast it to 100%.
@@TechnicallyJeff No, I try not to go to dealers unless absolutely necessary. I have no issues so far with my 12v and rarely go below 20% for a few hours at most. I've only seen the blue charging light 1 time at night when I woke up at 3am and had to look up what it was. Lol
You definitely want to get SC302. The ICCU issue is something that you won't have an issue until you do, and then at that point you'll need to be towed somewhere.
2023 EV6 Wind here ICCU recall update done. Just plugged it in at about 80% charge and it immediately started charging at 7kw (that's the max that my home charger puts out), no ramping up.
My GT has all the latest updates and no more open recalls. I have the Grizzl-E charger and when I plug it to the GT, it doesn’t exhibit the delayed ramp up charging that you are experiencing.
I have the Hyundai Ioniq 38kWh and on AC charging it does the same. It's a BMS controlled feature where it's the initial battery temperature related. My single phase 32A AC charge (UK) starts at 4.8kW then after several minutes slowly ramps up to 6.9kW maximum. However if I return from a drive and plug in straight away then it goes straight to 6.9kW. It's a Hyundai Group charging feature on all of their cars.
@@TechnicallyJeff The battery temperature may still be low even though the outside ambient temperature is hotter. I also thought my home charge unit had an issue but it's the car's onboard BMS controlling the kW rate outcome, well at least for the Ioniq 28kWh and 38kWh. Hope you find a solution but I now just live with it.
Also no issues with my EV6 GT Line, but we're doing 3 phases at 16A in Europe. I think it has to do with the 48A overheat mitigation brought forward by the IONIQ Guy. Check out his videos.
What was the air temperature when you were charging Jeff? I had the ICCU update and afterwards charged my Wind RWD with my Grizzle charger and the charging stopped around 90%. I started it again using the app and it charged all the way to 100%. The air temp was in the low 90's, so I thought maybe the battery was getting too hot and it shut itself off.
Not experiencing this with our 2023 Wind RWD EV6 though we are scheduled for the ICCU software update on 6/8. It should be noted, we had its 8k service about 6 weeks ago and was assured we were current on software updates at the time. Some other information worth noting: Home charger is on 50 AMP breaker (e.g. 40 x 240 = 9.6kW at peak efficiency) ... The EV6 regularly gets to around 9.2kW immediately and stays there for charge duration. Strangely enough, our other EV (2023 Wind Niro EV) was hitting 9.6kW regularly, however in the past couple of months, it has begun to experience regular charge interruptions. We've throttled back on charge rate, both with using the onboard toggle feature (to 90%) and via our Chargepoint app. Still trying to find the sweet spot charge rate, but it appears to be around 8kW.
I have noticed slightly different charging characteristics since getting the ICCU update on my GT Line in NZ. It has always charged at 11.2 kw on my Tesla Wall Connector (3 phase ). Now it charges at 11 kw, easing back to 10.9 kw towards the end of the charging session.
I've been having the opposite problem, my EV6 GT-L2 (with ICCU update) recently started charging at 9.5 Kwh and then drops off to 5.5 Kwh when I check it a couple of hours later. This appears to be unrelated to the ICCU update, as i did notice this happen on occasion before the update.
This is after having a TSB (ELE283 in the USA) completed. It throttles speeds when the charge port gets too hot as opposed to stopping charging completely.
Interesting, I finally got my car back after 4 months for the ICCU issue. The ICCU and the fuse were both replaced. I noticed when I was doing a "quick" charge at IKEA the other day (just wanted a 5 mile buffer to get home after a 300 mile trip). It only charged at 5.7k for the 15 minutes I was there. This was a Chargepoint level 2 charger, so I just assumed that was the max rate. When I got home with my battery at 3% I put it on my level 2 charger and it went straight to 9kw.
No problem with mine. The only time I had a slow charge like 3.3, was after installing a new level 2 charger, ChargePoint . Once changed the settings on the Chargepoint box, it started giving 48amp.
My 2023 Ioniq 5 AWD Limited does not do this. I have had all the TSB and recalls done on it and it fires right up at 40 amps on my Juicebox 40. I was having problems with it overheating the port and tripping out at 238 degrees. Had it in last week and they applied a TSB that I had not heard of and said it should fix that. Don't know yet as they charged it up to 100% and I have not needed to charge yet. Prior at times it would drop the rate to 50% and sometimes go backup, sometimes not go up and sometimes just stop charging. It would do the same at 35 amps, but would mostly work OK at 32 amps. Never had problems charging at 40 amps until they started applying these stupid TSBs.
We have a 2023 EV6 GT and do not have the latest ICCU update from the dealer. I have noticed the 3 min ramp up behavior recently and we also started having charging issues where at 100% rate, the car will stop charging. We have had to reduce the rate to 60% on AC charging. DC charging no issue. We have never had AC charger issues until recently so I assumed an OTA update caused this issue. Incredibly annoying!
Oh really? Hmm interesting. The OTA updates don't impact charge rates. I'm really curious about this. Have you had the ELE295 update completed or checked the charge port temps?
@TechnicallyJeff Just had to look up what that was, lol. Not to my knowledge, but the charger port/plug does feel warm but not hot by any means and has not been an issue for us ever until recently. We have also owned the vehicle for almost 1.5 years and didn't experience this in warm weather last year. These problems are new and so is that slow charging at start.
Yeah unfortunately the hot charge port causing charging to stop doesn't seem to happen immediately. It seems to happen over time, maybe as the charge port pins get dirtier or something. I'd recommend talking to your dealership about it. They can do the ELE295 TSB which will allow it to charge at full speed until it gets too hot, then it will slow the speeds to the 60% at that point.
I hav a 2023 GT and can only charge at 60% also. If i plug into a 40 amp charger at 100% charge speed the car lasts about 8-10 minutes before I get a charger disconnect error. Dealer can not re create the issue, mainly because the charge point chargers at the dealers only go up to like 5kwh. My local Kia dealer actually ordered me and gave me the recommended charger Kia sells in service to try out. Jeff, I have tons of videos and documentation of this if you want to talk about it more. Kia really is just ignoring it but I know im not the only one.
That's really annoying. I'd reach out to Kia corporate filing a complaint. If the dealership can only charge at 5 kW, they need to take your word for it at that point or find a way to test it properly.
I've had the ICCU update done in late March, and though the temperature hasn't really gone above 20 Celsius, I am consistently getting 10.7-10.8 kW, peaking at 10.9 from my EVSE.
@@TechnicallyJeff this is the latest one. I kept pestering the dealership for the update. I was their guinea pig for the install, the called me the day it became available. Edit: I stand corrected (by my wife) we went into the dealership end of Apr for the iccu update.
EV6 GT here. My car does not do this. I also haven’t went in for the ICCU recall because I want to see how it plays out and I’m not sure if I want to bring it in any time soon with there still being consistent issues. I have my ChargePoint set to 25 amps on purpose so I charge slower hoping to not get any ICCU issues. I also got the Ohmmu 12v Lipo. I charge every night to 80-90%. I usually only use about 20% SOC daily depending if I race someone or am running behind for work. Pretty neat trick with the car scanner app on the screen. I love only used my phone. Gonna have to try it out on the way home.
I got a GT too. I got my ICCU updated around 3 weeks ago. Ever since then I haven't seen my 12V amber light come on at all. Prior to this it would come on every now and then. Better safe than sorry I would say.
@@volcalstone mine comes on occasionally just sitting in my garage which is fine and normal operation from what I’ve read. I got a jump box in the frunk and the spare KIA battery is sitting at about 60% SOC in my garage
@@andrewmcmillan8110 yeah I know it's normal that it comes on and off but less the better I guess. I know you upgraded your battery so that's good. Hopefully I won't have to do the same thing. Yeah I got a portable jumper as well in my car just in case.
Very interesting. Yeah 25 amps is smart if you don't need the faster speeds. And yeah Car Scanner on the screen is very nice. That's how I view it 90% of the time.
I noticed this the other day (post ICCU recall) - but when I disabled my home's AC, it ramped back up at the same time. I have an emporia. No idea if it was coincidence.
@@TechnicallyJeff My understanding was that the emporia was smart in this regard, but I could have misunderstood what I was reading- it's been a while and I was new to all of this when I purchased it.
I think it needs to have the load balancing stuff installed for it to recognize that. Is it possible it was within the first 3 minutes of charging and you just happened to disable the AC when it ramped up at the 3 min mark?
My Ioniq 5 recently charged at a maximum of 25kW on a new installation of 150kW chargers. I tried several, all maxing out at 25kW. Didn’t leave it long enough to see if it ramped up after 3 mins. I called the provider, and they could see it was an Ioniq 5, however they commented that it was the car that was limiting the charge rate to just 25kW. Went to a Tesla s/charger and ramped straight up to 150kW/h. These chargers are brand new and run by Smart Charge in the UK. Maybe this is as a result of the recent update. Will try again soon and leave it to sit for 5 mins, just in case.
DC charging has nothing to do with AC charging. The interesting part of this comment is, in the US 800V cars get ~100kW max at Tesla superchargers. Curious why you’d get 150 in the UK at a Tesla charger.
Not any real "insider" info. I have the PDF on my website here - technicallyjeff.com/kia-ev6-technical-service-bulletins - it's a service campaign (voluntary recall) and supersedes the ELE283 update many have had completed.
I wouldn’t charge my EV6 more than 6-7kWh on AC chargers even after ICCU update since it was the main issue causing ICCU damage and I’m not sure if recall even fixed that.
@@keegan854 yes, many people reported ICCU problems after charging their EV6/IONIQ5 using 11kWh AC chargers in hotels and other places. 6-7kWh range seems safe so far.
My EV6 GT Line will not charge on my level two 50 AMP home charger more than 10 min before shutting off. Adjust the AMP to get the car to start consistently charge so it will be charged by morning. Problem with this is, its not taking 8 hours intead of 4 or 5. Im really about to trade it. Ive had it back to kia 4 times for 4 different problems and recalls. And its just to the point of being annoying. If I wanted to be a beta tester, I would have bought a tesla.
@@TechnicallyJeff Ive actually went to the dealership, said this is still a problem and the ICCU recall did not resolve it. They then said we need it for five days. I was like give me a loaner, and I was told a customer rep would call me. Crickets for two weeks. And nothing but a run around. Im calling corporate
That's crazy. It's a very well known issue and ELE283 is designed to throttle the speeds if it gets too hot as opposed to stopping charging altogether. They can easily see this with that TSB notes. I have no idea why they'd need it for more than a couple hours, let alone days.
Every new EV charger in the United Kingdom has a “random delay” of up to 10 minutes whenever an EV starts to charge. That’s the UK Government’s rules for home and workplace charging of EVs intended to avoid grid overload at peak times. Are you sure it isn't the charger in combination with the grid simply applying a lower rate?
@@TechnicallyJeff weird, a mine is a Canadian AWD GT-Line; I just got the ICCU recall done 2 days ago, but so far it goes straight to 9.6kW as usual on my charger at home.
Hi. This behaviour of your EV 6 is weird. I own an EV6 in a really basic trim with a 58 kWh battery. And mine doesn’t do anything like this. It charges on the max rate from the start. Every single time. Frank
As you mentioned, there was a software update to lower the charge rate when it is overheating. Previous to this, the charging session would stop completely. There is a class action lawsuit for this issue as well.
That's not what this is. The ELE283 TSB was released to throttle speeds if the charge port gets too hot, as opposed to stopping charging. This is different.
@@TechnicallyJeff And the class action is laughable. The sensor is doing its job throttling charges when the port gets too hot which has been traced back to compromised charger handles and dirty charge ports. And even if it goes anywhere, we’ll get a coupon for 5kW at EA…
@@TechnicallyJeff That I disagree with. This issue isn’t specific to these cars. It goes back 10 years on various cars. Heat comes from resistance which comes from poor contact which comes from misused, abused, dirty contacts. Only thing the car does is monitor the temp to protect itself. I’ve seen no evidence that the cause is inherent to the cars.

It wasn't that specific TSB number, but possibly. I'd talk to the dealership about it.
I have noticed slightly different charging characteristics since getting the ICCU update on my GT Line in NZ.
It has always charged at 11.2 kw on my Tesla Wall Connector (3 phase ). Now it charges at 11 kw, easing back to 10.9 kw towards the end of the charging session.
Hmm interesting
I've been having the opposite problem, my EV6 GT-L2 (with ICCU update) recently started charging at 9.5 Kwh and then drops off to 5.5 Kwh when I check it a couple of hours later.
This appears to be unrelated to the ICCU update, as i did notice this happen on occasion before the update.
This is after having a TSB (ELE283 in the USA) completed. It throttles speeds when the charge port gets too hot as opposed to stopping charging completely.
Interesting, I finally got my car back after 4 months for the ICCU issue. The ICCU and the fuse were both replaced. I noticed when I was doing a "quick" charge at IKEA the other day (just wanted a 5 mile buffer to get home after a 300 mile trip). It only charged at 5.7k for the 15 minutes I was there. This was a Chargepoint level 2 charger, so I just assumed that was the max rate. When I got home with my battery at 3% I put it on my level 2 charger and it went straight to 9kw.
Oh really? That's interesting. The Chargepoint may have been set to something like 26 amps or something.
2023 EV6 GT-Line AWD (Green edition) - no delay in charging at full rate. This is after the ICCU recall was performed.
Good to know. All other updates done?
Yes AFAIK
Thanks!
No problem with mine.
The only time I had a slow charge like 3.3, was after installing a new level 2 charger, ChargePoint .
Once changed the settings on the Chargepoint box, it started giving 48amp.
Thanks for sharing. What model/trim is yours?
My 2023 Ioniq 5 AWD Limited does not do this. I have had all the TSB and recalls done on it and it fires right up at 40 amps on my Juicebox 40. I was having problems with it overheating the port and tripping out at 238 degrees. Had it in last week and they applied a TSB that I had not heard of and said it should fix that. Don't know yet as they charged it up to 100% and I have not needed to charge yet. Prior at times it would drop the rate to 50% and sometimes go backup, sometimes not go up and sometimes just stop charging. It would do the same at 35 amps, but would mostly work OK at 32 amps. Never had problems charging at 40 amps until they started applying these stupid TSBs.
Good to know. Yeah they applied the TSB which will throttle the speeds if it gets too hot as opposed to stopping altogether.
We have a 2023 EV6 GT and do not have the latest ICCU update from the dealer. I have noticed the 3 min ramp up behavior recently and we also started having charging issues where at 100% rate, the car will stop charging. We have had to reduce the rate to 60% on AC charging. DC charging no issue. We have never had AC charger issues until recently so I assumed an OTA update caused this issue. Incredibly annoying!
Oh really? Hmm interesting. The OTA updates don't impact charge rates. I'm really curious about this. Have you had the ELE295 update completed or checked the charge port temps?
@TechnicallyJeff Just had to look up what that was, lol. Not to my knowledge, but the charger port/plug does feel warm but not hot by any means and has not been an issue for us ever until recently. We have also owned the vehicle for almost 1.5 years and didn't experience this in warm weather last year. These problems are new and so is that slow charging at start.
Yeah unfortunately the hot charge port causing charging to stop doesn't seem to happen immediately. It seems to happen over time, maybe as the charge port pins get dirtier or something. I'd recommend talking to your dealership about it. They can do the ELE295 TSB which will allow it to charge at full speed until it gets too hot, then it will slow the speeds to the 60% at that point.
I hav a 2023 GT and can only charge at 60% also. If i plug into a 40 amp charger at 100% charge speed the car lasts about 8-10 minutes before I get a charger disconnect error. Dealer can not re create the issue, mainly because the charge point chargers at the dealers only go up to like 5kwh. My local Kia dealer actually ordered me and gave me the recommended charger Kia sells in service to try out. Jeff, I have tons of videos and documentation of this if you want to talk about it more. Kia really is just ignoring it but I know im not the only one.
That's really annoying. I'd reach out to Kia corporate filing a complaint. If the dealership can only charge at 5 kW, they need to take your word for it at that point or find a way to test it properly.
I've had the ICCU update done in late March, and though the temperature hasn't really gone above 20 Celsius, I am consistently getting 10.7-10.8 kW, peaking at 10.9 from my EVSE.
That's the older one. Have you had the new ICCU recall software update?
@@TechnicallyJeff this is the latest one. I kept pestering the dealership for the update. I was their guinea pig for the install, the called me the day it became available.
Edit: I stand corrected (by my wife) we went into the dealership end of Apr for the iccu update.
Ahh gotcha. Yeah end of april is more like it lol. March it wasn't available. Thanks for the info!
GT owner here, and the car it’s doing the same thing as yours, before and after the recall. 2023 ev6 gt charging with Wallbox 40amps.
Before and after? Hmm interesting, maybe it's a GT thing?
Maybe it is. Sadly the recall didn’t fix the ac charging overheating @ 40 amps. I can only charge @ 32 amps with no errors 😢
Aww that sucks
EV6 GT here. My car does not do this. I also haven’t went in for the ICCU recall because I want to see how it plays out and I’m not sure if I want to bring it in any time soon with there still being consistent issues.
I have my ChargePoint set to 25 amps on purpose so I charge slower hoping to not get any ICCU issues. I also got the Ohmmu 12v Lipo.
I charge every night to 80-90%. I usually only use about 20% SOC daily depending if I race someone or am running behind for work.
Pretty neat trick with the car scanner app on the screen. I love only used my phone. Gonna have to try it out on the way home.
I got a GT too. I got my ICCU updated around 3 weeks ago. Ever since then I haven't seen my 12V amber light come on at all. Prior to this it would come on every now and then. Better safe than sorry I would say.
@@volcalstone mine comes on occasionally just sitting in my garage which is fine and normal operation from what I’ve read. I got a jump box in the frunk and the spare KIA battery is sitting at about 60% SOC in my garage
@@andrewmcmillan8110 yeah I know it's normal that it comes on and off but less the better I guess. I know you upgraded your battery so that's good. Hopefully I won't have to do the same thing. Yeah I got a portable jumper as well in my car just in case.
Very interesting. Yeah 25 amps is smart if you don't need the faster speeds. And yeah Car Scanner on the screen is very nice. That's how I view it 90% of the time.
Oh really? Hmm @volcalstone
I noticed this the other day (post ICCU recall) - but when I disabled my home's AC, it ramped back up at the same time. I have an emporia. No idea if it was coincidence.
Oh really? Interesting...
@@TechnicallyJeff My understanding was that the emporia was smart in this regard, but I could have misunderstood what I was reading- it's been a while and I was new to all of this when I purchased it.
I think it needs to have the load balancing stuff installed for it to recognize that. Is it possible it was within the first 3 minutes of charging and you just happened to disable the AC when it ramped up at the 3 min mark?
2023 EV6 GT Line, goes straight to 9kW on 40A at 100% setting.
Thanks Phil!
My Ioniq 5 recently charged at a maximum of 25kW on a new installation of 150kW chargers. I tried several, all maxing out at 25kW. Didn’t leave it long enough to see if it ramped up after 3 mins. I called the provider, and they could see it was an Ioniq 5, however they commented that it was the car that was limiting the charge rate to just 25kW.
Went to a Tesla s/charger and ramped straight up to 150kW/h.
These chargers are brand new and run by Smart Charge in the UK. Maybe this is as a result of the recent update. Will try again soon and leave it to sit for 5 mins, just in case.
Hmm sounds like a DC charger issue there if it worked at the Tesla supercharger.
DC charging has nothing to do with AC charging.
The interesting part of this comment is, in the US 800V cars get ~100kW max at Tesla superchargers. Curious why you’d get 150 in the UK at a Tesla charger.
Doesn't UK have 800v Tesla V4 chargers?
@@TechnicallyJeff Got me. As far as I know none of their chargers are over 400V.
I'm pretty sure I've read V4 is overseas.
Did I read that you replaced the stock tires on the GT too?
Yeah I got some used Michelin Pilot Sport All Season 4s with >90% tread.
@@TechnicallyJeff Great tires although there’s like 10 variants of the Pilot 4S.
Yeah these are the pilot sport all season 4. It has better ratings than the others and is better for low rolling resistance too.
Any insider info on SC311?
Not any real "insider" info. I have the PDF on my website here - technicallyjeff.com/kia-ev6-technical-service-bulletins - it's a service campaign (voluntary recall) and supersedes the ELE283 update many have had completed.
European versiongt line. I have the iccu update. Mine does not do this. Maximum power from start. 10,9 kw.
Thanks for sharing
I wouldn’t charge my EV6 more than 6-7kWh on AC chargers even after ICCU update since it was the main issue causing ICCU damage and I’m not sure if recall even fixed that.
I'm wondering if the ICCU recall throttles the first few minutes to avoid spikes as it ramps up.
Interesting, this is the first I've heard of fast AC charging as a cause of ICCU failure
Yeah supposedly excessive amperage and heat can be a contributing factor.
@@keegan854 yes, many people reported ICCU problems after charging their EV6/IONIQ5 using 11kWh AC chargers in hotels and other places. 6-7kWh range seems safe so far.
yeah personally i charge at 30A-40A
My EV6 GT Line will not charge on my level two 50 AMP home charger more than 10 min before shutting off. Adjust the AMP to get the car to start consistently charge so it will be charged by morning. Problem with this is, its not taking 8 hours intead of 4 or 5. Im really about to trade it. Ive had it back to kia 4 times for 4 different problems and recalls. And its just to the point of being annoying. If I wanted to be a beta tester, I would have bought a tesla.
Yeah that's frustrating. It sounds like you haven't had the ELE283 completed? Have you addressed it with the dealership?
Same issue here with my 40amp level 2 home charger. Cant charge at 100% for more than 10 minutes before shutting off.
@@TechnicallyJeff Ive actually went to the dealership, said this is still a problem and the ICCU recall did not resolve it. They then said we need it for five days. I was like give me a loaner, and I was told a customer rep would call me. Crickets for two weeks. And nothing but a run around. Im calling corporate
That's crazy. It's a very well known issue and ELE283 is designed to throttle the speeds if it gets too hot as opposed to stopping charging altogether. They can easily see this with that TSB notes. I have no idea why they'd need it for more than a couple hours, let alone days.
Every new EV charger in the United Kingdom has a “random delay” of up to 10 minutes whenever an EV starts to charge. That’s the UK Government’s rules for home and workplace charging of EVs intended to avoid grid overload at peak times.
Are you sure it isn't the charger in combination with the grid simply applying a lower rate?
Interesting. Yes, that's 100% not the case in the USA where I live.
Interesting. But I have not had this issue. I think might be the ICCU recall.
Yeah that's what I'm thinking.
My 2022 GT N-line does this also.
Good to know! What updates have you had?
2024 ioniq 5. Goes straight to 11kw on chargepoint home flex
Thank you!
Try cleaning the contacts
That wouldn't impact this
Mine charges at a sweet 1.3kWs Level 1 FTL
Oh man haha. That's okay. 1.3 kW is doable if you just top off every night. That's what I did the first year I had my Niro EV.
Mine does not do this. I have my Juicebox set to 32a. Car set to high speed. I have had the ICCU update done. 22 Wind AWD.
Good to know!
@@TechnicallyJeff just checked again. Plugged in, went straight to 7.2kw, which tracks for 32a setting on Juicebox 40.
Thank you!
My AC charge rate got bumped down to 90% after a 12v battery hiccup. I had to manually set it to 100% again.
That's weird. Mine was set on 100% though. I verified. And I went back and forth between 60% and 100% to make sure that didn't need to trip something.
@@TechnicallyJeff weird, a mine is a Canadian AWD GT-Line; I just got the ICCU recall done 2 days ago, but so far it goes straight to 9.6kW as usual on my charger at home.
Thanks for the info
Might be temp related?
No, not at the initial charge. It was 85 degrees out. Charge rates don't throttle until 220+ degrees.
My Ev6 GT does the same thing
Yeah, exactly same thing? Have you had the SC302 ICCU recall completed?
Exactly the same and yes ICCU recall was completed.
Good to know!
Hi. This behaviour of your EV 6 is weird. I own an EV6 in a really basic trim with a 58 kWh battery. And mine doesn’t do anything like this. It charges on the max rate from the start. Every single time. Frank
Have you had all the updates?
@@TechnicallyJeff yes. I got every update that was offered by KIA.
Thanks!
As you mentioned, there was a software update to lower the charge rate when it is overheating. Previous to this, the charging session would stop completely. There is a class action lawsuit for this issue as well.
😂😂
That's not what this is. The ELE283 TSB was released to throttle speeds if the charge port gets too hot, as opposed to stopping charging. This is different.
@@TechnicallyJeff And the class action is laughable. The sensor is doing its job throttling charges when the port gets too hot which has been traced back to compromised charger handles and dirty charge ports. And even if it goes anywhere, we’ll get a coupon for 5kW at EA…
Yeah I don't see it going anywhere. That said, it's definitely a vehicle issue too.
@@TechnicallyJeff That I disagree with. This issue isn’t specific to these cars. It goes back 10 years on various cars. Heat comes from resistance which comes from poor contact which comes from misused, abused, dirty contacts. Only thing the car does is monitor the temp to protect itself. I’ve seen no evidence that the cause is inherent to the cars.
iccu recall
