Power From Charger

[JahDuv]

I have a 120 V home charger a trickle charger and I have some accessories like a refrigerator in my Rivian R1 S quad that I keep powered continuously... for some reason I can’t get to the setting where you force it to pull power directly from the charger for the accessories so as to not deplete battery life please help me find that setting. Thank you.

I'm not sure I understand the issue.

Your trickle charger is being used for what? Is your fridge plugged into the trickle charger when the Rivian is parked in your home? If so, then the fridge is obviously not using the vehicle power.

If your fridge is plugged into the outlet in the Rivian, then power is coming from the vehicle's main high voltage battery. There's nothing you can change. If the Rivian is parked in your garage and the fridge is always on, you are using your HV battery. In fact, I don't even know if the outlets continue working that long unless you're in camp mode 24/7.

So I guess I don't understand. What's the trickle charger doing? What's the fridge plugged into?

Accessories run off the 12V battery. The HV battery charges the 12V battery when needed.

But if the fridge is plugged into the 110v outlet in the Rivian, that's using the main high voltage battery.

By "accessories", you're talking about the basic things that are part of the vehicle (interior lights, etc), not things plugged into the 110v, right?

To my knowledge, the only thing that can pull 'directly from the charger' is HVAC. It's a setting in the vehicle when setting up a charging schedule.

And if you are trying to charge the truck & run a fridge at the same time, using a 120v charger is not going to provide enough power.

Do you mean the included Rivian 120v charger? Or an actual trickle charger you have hooked up to a 12v battery?

You cannot. Your outlets wont even stay on 24/7 unless you stay in camp mode constantly.

Yeah, I'm confused as to what the OP is talking about. When he said "trickle charger" I went straight to assuming the 12V was being used. I power my fridge with the 12V since it's more efficient.

I believe you're correct that the 120V outlets are run off an inverter attached to the HV battery.

Regardless, there is no such thing as drawing power directly from the charging circuitry - all power comes from the batteries and the HV battery is topped off when it gets low and it in turn tops off the 12V when that gets low. Assuming you have the vehicle plugged in.

What about this?

LOL, if you want to believe an AI go right ahead. But then why bother asking real people like us?

There's only one charging circuit, which goes directly into the HV battery. There's no HV battery bypass that would allow the wall charger to power the 120V outlet directly.

Thanks. I’ll try that. I knew I had even seen the setting on my Rivian I just couldn’t remember where…

That is a garbage AI, stop using it.

I believe any 12V accessory is run off the small 12V battery directly and the vehicle charges the 12v off the HV battery. It is not directly from the HV battery. Given the tiny factory 12v and limited duty cycles I wouldn’t run a 12V item continuously in the vehicle, especially while it is off.
