    Is it possible to charge your Rivian while traveling with a portable generator to increase range while towing airstream?

    Typically, electric vehicles can't charge while in operation. I haven't seen any mention of Rivian being able to do this.

    In the video in this post, a generator is used to charge an EV but it's not as straight-ahead as you'd think and it's a pretty heavy piece of equipment to haul around. The Rivian vehicles will all have large battery options and offer lots of range. With various charging networks really starting to create good coverage across the country and Rivian itself announcing charging at adventure destinations, I don't think many would find an onboard generator the best solution.

    We're wondering about using the solar panels on our travel trailer for auxiliary charging, but like Domenick says, it would be anything but straightforward. Especially while driving. But we can envision doing it while parked - using our inverter to provide 110V AC (standard wall plug) for slow charging of the truck. It wouldn't be much, but in the summer we have excess energy and it would be great to put it to practical use. Looking forward to testing it (next year??) and will report back.

    The short answer is no. Read this in another forum and I believe the source of the information came from Rivian.

    Ah, what video? :confused:

    Nice catch! I've added the link to the post now, but here's the video that's in it.

    I do love the idea of solar on campers. I think we'll see a lot more of this, along with battery storage in the future.

    On the fly charging isn't going to be available for a long time simply because there isn't enough surface area on a vehicle to mount enough PV cells to make much of a difference. A good panel will produce about 300W per square meter it is pointed directly at the sun, the sun is well above the horizon and there are no clouds. People seem to have trouble grasping that you can't practically mount a tracking array on a moving vehicle and even if you could the sun isn't up all day nor at all on some days.

    But yes, you can charge when parked from a generator or solar arrays. Just don't expect much from either. The video shows a 7 kW generator. That's equivalent to about 28 panels on a clear day near the summer solstice.

    Then it's probably best you're not on the Lightyear One's engineering team. ;)
