  • Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my car" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your G70, please post in the G70 section - and so on... This message can be closed by clicking the X in the top right corner.

For a couple of weeks now my GV60 has been charging no faster than 42 kw at high speed chargers rated for much higher kw.

Does not matter the temperature or percentage. Chargers are also indicating that the vehicle is limiting the charge rate.

Anyone experiencing this?
 
Looking to update and upgrade your Genesis luxury sport automobile? Look no further than right here in our own forum store - where orders are shipped immediately!
Many variables at play for DC charging. What were the conditions when you attempt to charge? Ambient temperature, battery preconditioning, prior driving, SOC, etc.
 
Sounds like you are experiencing Hyundai's "fix" for their charger overheating problem--by fix I mean a software update that they pushed out to limit the charge rate to prevent overheating.

I believe the fix is only for L2 AC charging, not DCFC. I haven't heard of overheating with DCFC with the GV60

I thought the fix was for all vehicles using 800v e-GMP because the problem was the connector itself overheating? I know GV60 is on the list of affected vehicles.

Correct, but it's the AC connection overheating (for example, level 3 48amps 11.2 kW), not the DCFC connection (for example, Level 3 Electrify America 350 kW or 150 kW chargers)

The software fix or patch for Hyundai, Kia and Genesis EVs addresses the overheating issue experienced during Level 2 charging. Level 2 charging uses an onboard charger that converts the AC current provided during Level 2 charging to DC current into our batteries. When DC Fast Charging, the energy bypasses the onboard charger, and is provided directly to the battery pack. The overheating issues occurs somewhere in the AC conversion process, hence not showing up during DCFC.
 
Thanks for clearing that up. I got nothing then.
 
I assume it's Electrify America. Every single EA station around me has been de-rated since late Spring/early Summer this year. Some show up as 50kW in the app, others don't. Some show on the screen on the charger itself that it's been limited to prepare for upgrade, yes since Spring. Some chargers are shown as 50kW in the app but will output 80kW. After I unplugged last Saturday, a BMW iX plugged in and it was going at 38kW. It was going at 50kW for me in my GV60. Yes it's a complete mess.
 
I’m still new-ish and have only used EA a couple of times due to availability and proximity to my home. However, I used one on Thursday (Vacaville, CA) and was amazed at the power that rolled across. I got 236kW for a period. It did step down after a bit, but it was able to juice me much quicker than anticipated. I think I was connected for 17 minutes and went from ~40% - ~90%

When you’re getting consistently slow charging at EA stations or cabinets (40-70kW range) it may be a faulty charging cable that EA refuses to fix. There are EA stations that I avoid due to consistent slow charging speeds and others that are my go to stations because they are consistently fast.

I use the Plug Share app and see what EV owners say about their charging experience at EA locations I’m considering. If the speeds are consistently low, I avoid and look for stations with consistent higher output if that’s an option for me. You may not have a choice if you’re limited on SOC or location availability but this method has served me well in avoiding charging headaches.

Also, if you decide to leave feedback on Plug share, leave negative feedback for slow charging speeds. I’ve heard EA uses station ratings to prioritize repairs. So many people leave positive reviews for “successful” charging sessions that a station appears to be a good one when in fact consistently slow speeds are due to faulty EA equipment. Just my 2 cents.

EA charging is very frustrating. As you mentioned availability of the number of stations and chargers that actually work. In East Bay, CA a charging station with 4 150kw chargers all went off line for 2weeks. When it finally came back on line only 1 charger showed 150kw and the other 3 at 50kw each. There is another EA station near my house that went down a week ago. It's still not back up. It has 3 150 kw chargers. It will be interesting to see if they lower some them to only 50kw when they come back on line. I wonder if EA is doing this on purpose to discourage people with free charging to use the stations. I do most of my charging at home, but If I need a DC fast charge I have an EVGO station close by.
 
EA finally fixed the nearby station here. My GV60 charged from 25% to over 70% at near constant 150kW, but the oscillation is back with a vengeance - it was oscillating from like 60kW to 150 super fast when the battery was at around 48% SoC. The oscillation went on for a couple of minutes. It's kind of scary to look at and I can't imagine it's good for the car.

One of the EA stations near my home has been out of service for over 2 weeks. I just drove past it today and I noticed they are removing the older original chargers and replacing them with the latest updated chargers. I have no idea when they will be open for use. Has anyone tried any of the recent updated chargers and do they charge the car any faster?

I'm in the East Bay...
Where is this station?
