This is what they do but not to look better. They do monitor the SoC of the 12V battery and whenever it gets low the DC/dc converter kicks on and recharges it. This will be counted as phantom drain if it occurs when the truck is not it D or R.

It is definitely possible to do as demonstrated by Tesla but Rivian does not appear to do what Tesla does. Interestingly enough this is the one thing that makes my wife vastly prefer the Rivian. It doesn't have all that stuff that she doesn't understand.

Alas, no. I don't really know how it works but my best guess is that when you lay in a route it predicts SoC all along it using rated consumption, terrain and speed limit data. Whether it incorporates weather info or not I don't know. As you proceed along your route it reports actual SoC at...

You are asking the system to do something it cannot possibly do because the range remaining depends not only on how much charge is left in the battery but on what your consumption will be in the future - not what it has been in the past. One response to this is to have the displayed remaining...

These trucks have a "hold" mode. When you slow down sufficiently using regen eventually the vehicle transitions to the friction brake (H in a circle appears on the display). You can hear the friction brake or its actuator locking up. When you accelerate again the friction brake is released and...

The charger is about 90% efficient so if you charge 50 kWh you will produce about 5 kWh (17 kBTU) waste heat and if the phantom drain is a couple of kWh over night about 7 kBTU more. If this isn't disposed of the garage will warm up. In Virginia the garage is air conditioned so there is no...

They still sell the Mobile Connector (no longer called the Universal Mobile Connector) and adapters though they no longer include the Mobile Connector with the car. Interestingly enough I just saw a video in which a guy, his wife, 3 kids and a dog towed an Air Stream Classic from somewhere in...

I think it is clear that the thing that degrades the battery is that not all the lithium ions headed for the anode (charge) or cathode (discharge) make it to the intended destination. In this regard any current in either direction shortens battery life. But it also seems intuitive that an ion is...

Elon Musk has always advocated having the car plugged in at all times when it is not in use. Rivian's batteries are probably similar but not exactly the same. So ??? I discovered that if I just plugged the R1T in when I got home it would charge to 70%, discharge to 69.5%, recharge to 70%...

You will have to determine what your trailer's effective consumption is and add that to the vehicle's. I think ABRP defaults to almost 500 Wh/mi for the R1T which seems to me to be a bit pessimistic. It appears that 400 may be more like it but I am having a bit of trouble accepting that it is...

Stuarts Shops in Schodack worked OK for us on a recet trip through.

There is a sleep state and the object is to be sure your truck is in it most of the time when you are not using it.The problem is that no one can give you a procedure for putting the car to sleep though all the suggestions earlier in the thread do seem to help. When the truck is asleep you will...

That shouldn't happen. When the 12V battery (which isn't tiny at all - it's about the same size your ICE vehicle battery would be if it didn't have to crank the engine at -20°F) discharges the BMS senses this and recharges it from the traction battery. Of course the tration battery has to have...

My bad! Thinking of Tesla and Wallbox

If you see flashing LEDs then the cable is connected.

The easy answer is that there are no 120V circuits in the EVSE or the car and that there is no need for the neutral to be present. You would need to have basic understanding of how power is distributed to residences to fully understand this. Basically power is brought into your neighborhood at...

Your main panel breaker is determined in the same way as sub panel breakers. It must cover all the loads connected to it but as I have pointed out a couple of times already in this thread not all loads are treated the same. Code requires a certain allowance for lighting per square foot but...

The inspector may not always be right but he is always the inspector. In this case we have an EVSE load of 48 A and a receptacle into which a second 40 A EVSE can be plugged for a continuous load of 88 A. The pane/wiring must support 1.25 times that equal to 110A. This is for NEC compliance...

It’s not needed because the EVSE is behind a 60 A breaker.

Rely on what your electrician says. He knows what the local inspector will allow. I’m guessing (conservatively) that both the EVSE and the 14-50 are for vehicle charging and thus are both continuous loads and that the sub panel must support 120% of the sum of their loads. Now you can put two...
