I have a CT on order and may be about to buy a Super C Class RV (mid size diesel chassis) that can tow 15,000 lbs. I want to boon dock so may be away from chargers and love CT as large onboard battery can provide power off grid to the RV.

Question: While towing can I 'activate' the CT so that towing behind the RV recharges CT batteries through very mild re-gen?

Ultimately may add enough PV to do the job but in the meantime I wonder.

Thanks in advance,

Jay

Currently Tesla does not support a mode where you can tow one of their vehicles on it's own 4 wheels. There's a "Tow Mode" that can be activated temporarily to disable the parking brake and put the vehicle in the equivalent of neutral in order to winch it onto a flatbed. The "Tow Mode" is only active for a few minutes and only allows the Tesla to roll at a very slow speed. If the time runs out or the car rolls faster than the limit, the parking brake will be re-applied.

We don't know yet if Cybertruck will be different. Hopefully Tesla can see that people want the option and figure out a way to make it happen without increasing wear and tear to the drive units or battery pack.

As previously stated not an option and doubt it will be as not sustainable way to charge EVs.
In this scenario you might as well buy a gas generator to charge the CT and run the RV.

Well, there is viable way to charge the CT while going down the road with his new Super C RV

The RV has house batteries and an inverter. The inverter make 110vac for the plugs, TVs, coffee maker. While on the road, the house batteries are charged by the RV's engine (alternator). Basically free energy due to the extremely low current demands of charging the CT on a 15 or 20amp circuit.

The CT will have 110vac charger that comes standard. Run an extension cord the CT's charger and plug it in! The CT will now be charging via the inverter, via the house batteries, via the engine's alternator. All this is happening while you're on cruise control and staring at that driver's side rear view mirror.

Yeah yeah, obviously the charger plug will be sticking out the left rear corner of the CT, asking to be ripped right off by something. A flying deer comes to my mind.

But, it CAN be done if needed......

Assuming you were going to do this, you'd create a special plug and tie into the wiring elsewhere.

Dragging an EV to tow it is just a dumb idea. At worst, you're wasting gas. At best, you're gaining a couple percent as you normally use linked brakes.

I believe Rivian will allow this option. No idea yet how much of a hassle it would be to use it. It might require someone to be inside the Rivian to use the regen in tow mode.

I don't think it's possible with any other EV.

Here's a tweet about it:


In the Long Way Up doc I also saw them dragging the R1T behind a tow truck and using regen to charge the battery. It's incredibly wasteful in terms of efficiency, but they were in the middle of nowhere in South America, where the electrical grid was bad. It was literally the only way for them to recharge.

Hahaha, This thread reminds me of years ago when the work day would end and about 50 workers would be walking out to our cars. This one old welder dude would be behind everyone and yell out "hey asshole", just to see who would turn around!
So everyone who answers this guys question thinks they are a BRAINIAC. :D?
