Electric Toad
If you tow and electric car will the battery recharge while you are traveling? Seems like the vehicle could be set to recharge the battery by a switch selection.
Forum Discussion
I don't know anything about EVs, but have put some thought into the idea. Just what I know of other things mechanical and electrical, and some simple logic. It is a discussion I enjoy.
But what if the re-gen was controlled by the MH's jake circuit? Then the energy put into batteries would be some of what needs to be dissipated to slow the rig. Would need some way to pull power out of battery while towing because full charge would reduce braking power.
What cools the system when it is putting out power? Do they use a separate generator for braking? I have seen applications where battery voltage is put to the generator to start a engine, so assumed the drive motors would be used as gen to charge. I know a motor makes heat when powered to move a load. Does it make more heat when spinning on open circuit?

And don't forget the extra fuel used by the MH to generate that extra power. Lot of inefficiencies built into such a system
Yep, no free lunch. I think it would be more of a convenience. For what it’s worth, after 5 years of RVing with an EV in tow (on a trailer) it has never been a problem charging the EV. Either at the campground or mostly at commercial chargers while out sight seeing. Seriously folks, EV chargers are pretty much ubiquitous out there, and more and more every day. They just announced a 16 stall station at the local shopping plaza maybe 600 meters from our house. (12 Tesla v3 Superchargers and 4 public fast chargers) That and another dozen locations in the province, and there will be more announced next month.
Bottom line, don’t worry about charging your EV.

Towing a Tesla
There are all kinds of articles online. Some say a Tesla can't be towed, this one says yes.
One article I previously read said the charging system would overheat if the vehicle was being flat towed. (I believe it was a Tesla)
