Hi All!
This is my first post here and I wanted to share a story with you all and see if anyone has experienced anything like this. Our family owns a piece of property that has a little off-grid cabin on it. I had the Rivian there over the weekend and tried to charge it. Since the cabin has a small 2200 watt solar setup, it only has 110v available. I was only planning to be there for the day but I thought I'd give it a shot since it was free energy. The inverter in the cabin confirmed it was pulling about 1500watts of power after I plugged the Rivian in, but the Rivian app said it was only charging .6 miles per hour. Boo! Assuming 2 miles per kW-hr, that means it was only charging at about 300 watts, but using 1500watts? Now, I didn't expect 100% efficiency, but I also didn't expect 20%. I've gotta assume the 1300 watts was being wasted running a circulating pump and the fan.
Is that really necessary? Why bother adding the 110V plug if it basically doesn't work at all? Well, unless you just like wasting energy, that is. My bet is they just haven't gotten around to this yet. As a point of reference, my wife drives a Pacifica hybrid that takes 13 hours or so to charge 16kW-hr battery on 110V and gets about 33miles on a charge. About the same energy per mile as the Rivian. So hers is charging at 2.5 miles per hour. Slow, but much better!
So, what am I saying here? I think I'm saying, "Come on, RJ! You can do better than this!" I know this is a truck not an Aptera, but I really don't like wasting hard-earned energy. You can see the cabin and 2 of the 6 the solar panels on left (the panel on the roof is no longer functional).
