Slow Charging Question

[Slugworth]

Just picked up our new R1S yesterday, so forgive my ignorance. Installed the level 2 Rivian home charger on a 50amp, 240V breaker. Phone app shows I am getting 4mi/hr at 2.4kW charging speed. What have I done wrong?

Check the settings in the charging menu on the truck. Make sure you select the right amperage (40A) for a 50A circuit.

If you have the dip switch settings correct, and the truck wasn't manually lowered to that charge rate, call Rivian and ask for them to reset your charger.

It's stuck at a 12 Amp charging Amp in the vehicle and I can't seem to raise it.

It defaults to 48 when I unplug it and once I plug it back in it goes to 14 amps max

Your wall charger is signaling that it is hooked to a 15 amp breaker. Something is configured wrong for the wall charger. I don't own one but I believe the rivian app is how you configure the wall charger. It should be a different menu from setting the speed of the truck. If you missed that setting when you originally setup the wall charger you may have to call rivian to start over or something. Someone more knowledgeable will chime in.

Looks like you have the switches backwards. 12A and 40A look similar but all in the opposite positions.

If the switches are set to a lower setting you need to contact Rivian support to reset the charger for any higher setting. Switch the dip switches to the proper configuration then call Rivian for them to reset the charger.

Oh, wow, that is not user controlled?

Add that to the reasons to avoid Rivian branded EVSE's.

Yes, I understand the intent. They are trying to prevent someone from going in and over cooking a circuit once it is installed and setup but does make it harder to get the initial setup or upgrades handled.

In case it wasn't clear about the dip switch settings being backwards, here's the screenshot from the manual. (The white bits are the moving part of each dip switch and down is off/ up is on.)

Awesome, that was it. Thanks so much!
