Is there a setting on the updated Ioniq 5 for reducing the charge rate like there is on the older version? If so, it sounds like it has been set.

 

Strange, I was getting the exact same thing with my Ioniq 6 the other night, on my ChargePoint Home Flex. The settings in the vehicle hadn't changed, so I started fussing with the charger and the app (I'd definitely check the vehicle settings first though.)

I unplugged and tried a power cycle first, but that made no difference. Best I could tell, there was some sort of glitch in the charger, and it was only pushing 16 amps even though it showed as 32 in the settings. I ended up resetting my charger's WiFi settings, then changed my amp settings to 40 for a bit. Strangely, it still showed 32 in the app, but it suddenly started charging at 9.2, so obviously that did something. I then bumped it down to 30, then back up to my preferred 32 so that it would hopefully actually save that way (which, turns out it did.)

No idea if the same thing is happening here, but the timing seemed curious, so I thought I'd mention it. I also noticed that my charger happened to get a firmware update on the 26th, so I wonder if that did something.

 

Thanks for this I felt like I was going crazy not being able to find anyone else experiencing this. The settings on the new car are definitely correct, but I’ll see if I can reset the wall charger next!

 

One of the first things I do on new electronics, once I've established that it's working properly, is disable "automatic updates".

I'm a firm believer in the old axiom: If it ain't broke...don't "fix" it.

 

As someone who tests software for a living and therefore has a distrust for all things software, this is solid advice. 😆

Edit: as others have pointed out, make sure you eventually do install updates manually, for security purposes. I don't think the ChargePoint even lets you disable automatic updates though, so this probably doesn't apply here.

 

There are lots of things you can try for both diagnosis and stab-in-the-dark fixes, including:

• Test at a public (or friend's) Level 2 station
  • Bonus points: Test at a public Tesla Destination station, so as to remove the adapter from the equation
  • Note that the output of public stations varies; most are 30A or 32A at 208v or 240v, hence between 6.2kW and 7.7kW, but some are outside of this range. Check PlugShare check-ins, some of which note the received charge rate.
• Turn off and then on again the breaker for the EVSE
• Check the EVSE settings
• Check the car's charge settings
• Re-seat the J1772 plug to the adapter and the adapter to the car
• Try another adapter (not easy unless you have a friend with a NACS vehicle)

 

UPDATE: the issue was with the charger. I rebooted it from the app, plugged it in and it was back to where I expected it. Thanks for all the responses!!

I didn't know it ran on Windows. 😁 I'm glad you found the problem. Good job!! I quoted you down here and changed the title of the thread to make it more obvious that you're no longer seeking advice.

 

I’ve avoided any EVSE software update risk, and updates altogether, by getting an absolutely dumb, non-connected one. No updates ever, but no need for them ever either. All the smarts that EVSEs offer are also offered in the EVs themselves and that’s where I set them. My AeroVironment EVSE, acquired in late 2011 for my Nissan LEAF order, is simply a 32amp electricity pump, one that is still working today 14 years later just fine thank you very much and over the years has charged up that LEAF, a Tesla, and three Ioniqs.

 

FYI. If/when that EVSE dies, it's likely to be the micro-switch in the handle, that controls the Proximity Pilot signal. If you're at all handy with a soldering iron, it's replaceable.
