Fast Charging Failure

[UnsungZero_OldTimeAdMan]

The charging history suggestion was interesting. I forgot about that. The Trenton SC claimed their employee took my vehicle to an EA station and fast charged, but when I reviewed the history, the only charge that day managed 59 miles of range and took 2.5 hrs. Not exactly “fast charging”. I basically do that with my level 2 garage charger.

Could be miscommunication. Tested wrong car or misunderstood problem to be charging in general, not specific to fast charging. Good suggestion on video documentation, all of the steps involved. So they can see everything you did to arrive at the failure(s). Remove all doubt/excuses and elevate issue.

My local SC has DC chargers out back. I'd probably attempt to use them myself if this happened to me. If they worked, then I'd insist on getting a tech to ride-along to the closest station that wasn't working.

Several others (myself included) have had fast charging issues. Here's a thread where it's discussed and, specifically, to a post where I add some links to other threads where it is discussed (and resolved).

I'll note that taking video of the behavior, noting the time of the failure, doing a reset just after the failure, and calling support to establish a timestamp in their system all help with diagnosis and resolution.

You actually do not need to do a reset, simply turning flashers on and off triggers a log entry for them to trace.

Unless they changed it, supposedly long press on your name in the center display does the same thing.

I've found that EA works better starting the charging session thru the app (select location, select charger station, the use slide bar to start charging). For some reason EA tap-n-charge doesn't seem to work for me. Charge Point tap-n-charge works fine. Maybe get another Rivian (or another EV) to go with you to test the charger and your account.

They all work better if you initiate through the app…don’t bother trying to interact with the screen on any charger…

I would also be very frustrated if I couldn't get a fast charge. And I would be furious if Rivian looked at it, said it was ok, and then still couldn't do one, especially after trying three brands of chargers.

Also, the OP has a Lucid listed as another owned vehicle. If they aren't having problems at the EA/Evgo charging stations with the Lucid, their Rivian is the problem, not their account. @BradSholl , I would also try charging the Lucid and Rivian on the exact same station, within a few days of each other since its not convenient, and let Rivian know that your Lucid works fine, so its likely not an account or user error issue. I know its not exactly convenient, but just eliminates another excuse they can use. And I would stress that the Lucid has no issues (if it doesn't).

I would definitely try to get a tech to go with me to a charger. I believe Gaithersburg (around 2.5 hours each way for the OP, so not convenient) has fast chargers on site, but I do not know if they are as powerful as the EA/EvGo/Rivian chargers (which typically seem to be 150kw and up, or should be). So the results may be different if its ok charging at 60kw but not 150kw.

Update…a mobile service tech is coming in a few days with a NACS adapter and we’re going to the local Tesla fast charger (the nearest CCS is almost 20 miles away) so he can “get some data”. Then they’re going to arrange to take the vehicle back to Trenton for a second go around at fixing it. Doubt it will be fixed for my bike trip next week, but it’s progress.

Do you hear a repeated sound like in the video I posted on my earlier thread? I also had a tech meet me at a charger and... of course it worked that time. I certainly don't know all the communication that occurs between the vehicle and the charger, but the failure of this communication was making everything time out and fail to initiate the charge. Luckily for me, it happened at the service center and they chased it down to the Central Gateway Module. If they've already agreed to take your vehicle in for a spa treatment, I would kindly ask them to take a good look at whether you're having an issue with your CGM.

Good luck!

No noise at all. Tries to initiate charge for maybe 45-60 sec, then times out and tells me to unplug and try again.

What I find fascinating is that they claim it fast charged for them, but when I look at my charging history, the only charge session that day was for 2.5 hrs, gaining 25kwh and 59 mi of range. That’s level 2 speed, NOT DC fast charging.

Update…Dave, my local mobile tech came out with a Tesla adapter and we popped down to the nearby Tesla Supercharger bank for another whack at it. He had his laptop hooked up to monitor charging activity. Nothing! Timed out every time. Dave’s suspicion is the CGM. It goes back to Trenton next Monday for a replacement. Hopefully, this finally puts an end to this saga.

I hope the replacement fixes the problem! I had a similar issue while on holiday on Vancouver Island in August. No luck fast charging at 4 different charger locations within an hour. Once I plugged in, the Rivian would almost immediately tell me to unplug and try again. This had happened twice in the past year but seemed to resolve itself. I went back to the hotel and plugged in to a L1 outlet. I found the earlier thread mentioned here and went back to to an L3 to try again the next day and it worked. I took the vehicle to the Richmond BC service centre and after 5 hours of testing (!) they really couldn't diagnose the problem. It charged just fine at the service centre. They decided it was best to replace the charge port and attached module. Is that the CGM? I'll be going back for that soon. Was pleased that they didn't just send me away. As I wait, it is working just fine, even with my new A2Z adaptor at my local Tesla Supercharger.

I have this exact same issue - 80% failure initiating DCFC. When it does "take" it will charge for 1-5 minutes and fault with red ring around charger and error on driver screen to wait 15 minutes. Repeat attempts to charge at same charger are met with immediate red ring. Reboot of vehicle occasionally works if I switch to a different charger but will never complete a charge to target. Very random but impossible to road trip with. Have used many EA and Tesla SC with same result. Suspect defective CGM but can't get into service center until November so very frustrating.

According to Dave, level 1&2 charging are handled separately from fast charging, which requires the CGM. So, I can charge at home but not fast charge. Makes sense from my limited understanding.

Yes, you have it right. If it’s your L3 module you should be able to charge L1/2 just fine. Should be a pretty quick fix if that is the only issue.

L1 and L2 use AC charging. Different modules than high power L3 which uses DC.
