Hi. I had my car on the charger in my garage last night. I noticed my phone app was going off, and saying charging stopped.
I started the charge again and 30 minutes later it stopped again. This happened a few times. I have had this set up for
3 months with no issues. I did not know what to do so I put a box fan on towards the charger, elevated the cable off the ground.
I am not sure if this was the fix but it did not stop after and completed charge.
Does this sound familiar? I am using the grizzl e classic. The temps outside hit 100 yesterday, maybe it was just too hot in my garage?
Thanks!

I have encountered something similar (if not exact). Ever since the temps in SE Texas got above 90-F, then when I plug in my I5 to recharge at around 4 pm -- and the garage is > 90-F -- then it will stop charging on its own. There's no pattern I can discern on how long it will charge until it stops. Most nights, I've just waited until 8pm or so, then initiated the charging again, and that seems to work just fine.

Yesterday, I decided to see what happens if I re-start it again fairly soon after it quit, and this is what that looked like:

Rectangle Slope Font Parallel Pattern


It restarted, but it didn't take too long before it quit again. So I waited 15-20 minutes and tried again, and it then charged until it was at my pre-set point.

I haven't tried pointing a fan at it, but I think I will try that. It does seem to be very much heat-related.

P.S. Heat index yesterday was 102-F !!! It's hotter today.

ok that is a relief. I didnt want to mess with contacting Grizzl e ect.
is there a way to make it automatically try to start charging again after it shuts down? I would
hate to wake up and not have enough to get to work. I have long commutes.

I have a ChargePoint and it offers a schedule so that it will start charging at a specific time. It also has a reminder to plug-in, at a time you can set. But, automatically? Only if I was using the scheduling would it be mostly automatic. (And I have no idea what would happen if the charging were interrupted for any reason.) I do not think the car will do anything automatic. I don't ever re-charge using any of these, so I'm just not familiar enough to tell you more.

Last night I had the same issue again. I had the fan on to circulate the air around my charger too. I may
look into another brand level 2 soon. If anyone is charging in the high temps and not having this issue
I would like to know what charger you have. Thanks!

My garage gets toasty and Juicebox 40 I have charged without any issues though I only did it couple of times since my car has less than 1k miles.

Question: after driving the car long distance, is it OK to start charging right when you get home, or is it best to
let the car/battery cool down first? Maybe that could be my problem.
I also noticed in the screen settings, there is a charging speed option. I read if you have problems charging to lower the speed.
Does anyone have theirs set to medium or slow?

I found that pointing the fan at the charger does not help anything. Normally I started charging as soon as I get home around 5.30. The last few days I have
put the fan blowing under the car and letting it sit for a few hours in the garage until the sun starts setting. I started using the charging scheduling in the app to turn charging on at 8.30 PM..
This really did help, as the temps are still 100% and my charging has stopped with these interruptions.
it is still a little annoying that I keep checking my phone app late in the evenings to make sure it doesn't stop charging..

I am having the same issue with the ChargePoint Home Flex. It worked fine for 4 charges. Today I cam out to a 56% charged battery (set for 90%). I have not been able to charge it to 90% in 5-6 more tries.

I know this does not help much… But it seems clear that this is not a charger issue. This is an Ioniq 5 issue…

I wouldn't be surprised if Hyundai built in extremely conservative charging safeties, any deviation in the power being delivered causes charging to be stopped.....buuuutttttttt

What do your chargers look like when the car "stops charging"? Are the LEDs/lights on the charger indicating that no charge is being conducted (I have the chargepoint and I think it turns blue when I disconnect).

Have you tried charging at a public level 2? Same outcome? No issues using DC? I would still contact the EVSE customer service and report the issue so they can troubleshoot or replace the unit - and make a service appointment to confirm all is in working order. It kinda sucks to do....but only way to really start identifying what's really going on.

You can't say that until you consistently get the same results with other chargers. I will bet the issue is an overheating charger.
There’s been three separate charger brands sourced in this thread (Grizzl, Zaptec, Chargepoint). Maybe all three charger manufacturers have the same problem. But I’d suspect this is something related to the car…

I reduced the charge to intermediate/slower setting on the car and scheduled my charge for after midnight last night. It did finally charge to 90%.

Yesterday was hot in Vegas…but it was actually cooler than the four preceding days when the charger worked as advertised. I’m not sure how much heat is playing a role. Also…after reducing charging speed… I did have one failed charge before waiting until after midnight..,

My Chargepoint is blue when charging. It goes green when charging stops. So randomly it just goes green and quits charging.

DC works fine.

I’ve not tried a public level 2 yet…but that is my next problem solve…

Considering all those brands are (trying to) function in the Southwest heat wave I really think the common denominator is just plain heat - electronics don't do well in it. It sounds like you folks could toast marshmallows by waving them out the window, I hope for your sakes it eases up soon. All I can suggest is maybe restrict charging to night time and maybe in stages to allow cooldowns.

Many of the posts about problems with L2 charging interruption seem to me to have high amp connections -- e.g. 50A or 60A breakers. I wonder if changing the settings in the EVSE to charge at 30A or 40A when it is very warm might improve matters?

Zaptec has stated that they need to do an software upgrade on their chargers to support higher charging speed for the Ioniq 5. Something that is not unique to this car. Seems like the protocols and standards are lose enough to make it possible to implement non working functionality between wall charger and car.

I think I’m experiencing the same problem. I have had my Ioniq 5 for about 2 months with no issues. Then seemingly randomly it doesn’t charge all the way to 80%. I have a Wallbox level 2 charger 40amps. It seems to charge for 5 or 10% then stops. I was going to try the level 1 charger that it comes with to see if something is wrong with my Wallbox charger. Could it really just be the heat causing it to stop charging?

Any additional parameters that you can share? When do you charge - experiencing hotter than normal temperatures? Have you contacted wallbox?

Also....what are your AC charger current settings in the vehicle. Per manual:
"You can adjust the charging
current for an AC charger. Select an
appropriate charging current.
ś If the charging process does not
start or abruptly stops in the middle,
reselect another proper current and
re-try charging the vehicle.
ś Charging time varies depending on
which charging current is selected."
