Known issue charging over 40a?

[Christopher]

Is anyone having issues charging at above 40a?

My R1T starts charging and then every 30 minutes it errors out and stops charging for 10 minutes, then starts back up again. Below is a screenshot, it's like clockwork.

It's not isolated to a single charger, and is only happening on one of my Rivians. The vehicle that it is occurring with I've owned for over a year and it has just started having this issue recently.

I called support and they said "we are aware of this issue and a workaround is to lower the charging amperage to 30a or 32a."

That statement made me think that there may be a bulletin and that this issue is not isolated to just me, but when I asked if others were affected because they said they are aware of the issue they said "I don't know if there are others affected." Makes no sense...

They had no information to provide about affected vehicles, timeframe for fix, if it's a software update that's required or defective hardware, and couldn't offer me any assurance that someone would follow up with me about the issue.

The vehicle says it was a vehicle error and the EVSE says charging stopped by vehicle.

I feel as if it's overheating with the hot weather recently and the frunk is quite warm when this happens. Maybe it's shutting down to cool off and then starts back up when the temperature is back at an acceptable range?

They had me do both an infotainment and vehicle reset, and a breaker reset for the EVSE. The EVSE isn't the issue as it charges my R1S just fine and my R1T that has this issue experiences the same issue on other chargers at 42a.

Nevermind. Found a similar thread here. Couldn't find it originally because it's not in the Charging sub-forum.

Fixed in the next update.

yes having this exact same problem. Hopefully per the other thread it is eliminated in the next update. --though the rivian software account on twitter/threads released the next software update notes last night and I didn't see anything mentioned about this issue

• For AC charging, if the connector becomes too warm, the vehicle automatically lowers the power to safely continue charging, and a message appears on the driver and center displays.

I think this is the issue that people have been experiencing. Previously I think the truck would go into an error state, and if it goes to sleep after charging stops then it wouldn't resume.

Apparently there's some type of fix on this upcoming update https://rivian.software/2023-26-00/

But as @SunDevil2213 pointed out, this isn't really a solution. Previously for over a year we've been able to charge fine at 48a uninterrupted. Now it will be throttled down due to heat.

So why suddenly is this an issue? Something changed and now the handle gets too hot, and Rivian's fix is to throttle down rather that fix whatever they did that caused this?

Or maybe previously it was getting too hot and they were allowing it and that was causing failures and now this is the fix for that.

I have been charging since March of 2021 at home on this charger. And have never had any issues until the last week+. My handle doesn't feel hot. I really don't know what is going on. And unrelated perhaps, but I had to charge on the road once last week at a 150 kwh charger and it charged fine. Who knows....

Saw this on the R1S yesterday during the day. Garage gets to 90ish degrees in summer.

Will see if the R1T experiences the same thing when I charge later.

I have mine set to charge from 10pm-7am every night. This problem for sure did NOT occur last summer.

I lowered the amps on my charger from 48 to 40 and this issue BEGAN happening. Changed it back to 48 and have been good since. Using a Tesla wall charger and TeslaTap.

Odd I charge at work on a Ford 80a charger and it stays at 48A no issues?
