Couldn’t you instead add a massive battery to the trailer and physically connect both it and the trailer to the car. Essentially letting you tow a battery bank with extra storage? Like that you mitigate having to work out the safety issues and you don’t have to pay for another set of motors etc.
You could upsell it by the trailer being extra battery for when you’re camping f.ex… And it could be modular, accepting a camping to / flatbed/ whatever.
It’s a real shame that we can’t get swappable batteries in my opinion. Standardise the technology and retrofit gas stations. Maybe there could even be a smart way to use the batteries in storage as a buffer in the grid, needed with the increase of renewable energy.
Nicola already has a portable charging setup for its EV tractor trailers. At least they’re marketing one. I don’t know what’s actually in production.
But really there’s already an EV trailer with motors and a battery to make towing with an EV more possible. They picked a stupid name though. https://pebblelife.com/
why not both? make it a thing you rent when you need it that also extends the range of your EV when you are on a long road trip without making you haul around extra batteries/weight during your normal commute. If they did this with a data cable and a safety cable and allowed the caravan to share power with the tow car I think it’s actually a neat idea

Ford has filed for a patent

here is a french startup

and my personal favorite (no trailer, but 2 extra wheels for battery weight. (30 mpg in 1980)

Not surprised people are working on it.

Not yet for cars, but I’ll dream for now

I think the big advantage here is you could rent the doohickey, rather than buying a massive battery bank you’ll only use a few times a year.

The doohickey could still be attached physically to the car. It’s probably cheaper to add a hitch than the necessary tech for this to work remotely.
I can definitely see a use case for a powered dolly for vehicles with poor range or low towing capacity.
