Charging Slowed to heat. this is a defect

[BadRivian]

i am in North Carolina, I am getting sick of having to point a Fan at Charging Port on my R1S just so I can charge it at full speed.s this is a defect. I even park my R1S in my garage

Are you using an adapter to charge? Or is this a native plug?

 

[BadRivian]

I am using th native plug. ive used on my last 5 EV. i used it to charge my Hummer ev at 19.2k (80 Amps) never one issue

What speed are you getting? You can’t charge at more than 48 Amps with Rivian’s

Your post is pretty much missing any useful information. What exactly needs to be cooled. Are you cooling the charger, the plug or your Rivian?

 

[BadRivian]

I have it set to 48 Amps, I have a Commerical fan Pointing at the Charging port on the rivian and then it charges at full speed. I plug into my Hummer EV it works fine @ 19.2KW

11KW when it works most of the time 7KW.

Something is either wrong with the charger or the truck. I charge outside in 90+ heat in the direct sun and have never had my L2 charging slowed.

Curious how hot it is when you experience this.

My R1S only slows down on L2 when my garage exceeds 100 degrees.

This is a frequently reported issue where R1 will not support sustained 11.5 kW charging when ambient temps are over 85-90 degrees. The brand of L2 charger is not relevant to the problem. Don't know if there is a temperature sensor issue, overly conservative limits, or an actual thermal problem forcing the throttling. Pointing a fan at the charge port typically resolves the issue. Personally, I just accept that it won't take 48A in the summer and drop the charge rate down to 40A. There's no reason for me to need 48A charging... aside from the fact that it should support it.

My EV Charger has a screen on it.. and let me change the amps I am going to change it down to 32 amps and see what happens. This is a defect though. After to talking with Kyle its the Vendor they used for the Pins in the charging port

You can also control the charge rate in the Rivian's settings so it doesn't impact any other vehicles sharing the charger.

48amps at 240volts is 11.52KW, unless you are somehow cranking up to 80amps that is impossible.

As you probably know, heat in an electrical connection is caused by resistance, which can be caused by oxidation, etc. AN interesting experiment would be to use a high quality contact cleaner/lubricant (no CRC or WD40) like DeOxit. No connection to the company, just an extremely satisfied customer. This stuff works when the other stuff fails.

I had an issue like this last year with my Tesla branded Charger. It kept slowing down on hot days. They ended up replacing it and I have no issues now. I didn’t think it was my charger until I called them. I had O trouble codes and it was only doing it with one of my ev’s.
