This has been attempted multiple times before, but we've not seen it
done at highway speeds.

The fact that you can charge an electric vehicle by towing it in gear
is common knowledge among those with knowledge of how EVs work -
you're basically just relying on regen to put juice back into the
battery, using the motor as a generator. Many have attempted it as
more of a gag and more often than not in order to make a YouTube
video that will attract a lot of views; this latest attempt is no
different.

We're pretty sure very few people actually charged their EVs in this
manner, even when they completely ran out of juice and stopped on the
side of the road. Calling a tow truck seems like a safer bet than
towing your dead EV behind another vehicle to charge it back up
again...

Rich, the guy behind the Warped Perception YouTube channel, known for
many crazy perception-warping videos about cars and engines, had his
very own Tesla Model S towed behind another vehicle (a Mercedes-Benz
E55 AMG, no less) at a constant 70 mph and drew several important
conclusions.

Firstly, the vehicle did not display any error messages or any
warnings that what was being done to it was harmful to the vehicle or
unsafe in any way. It looked like it could take many more miles of
what it was being subjected to without issue.

Secondly, while towing the Model S at 70 mph, the battery was being
replenished at an accelerated rate. He had the car towed for some 25
miles, putting back electricity into the batter at a rate of 65 kW -
not quite Supercharger speeds, not even V1 or V2 Superchargers that
could muster up to 150 kW, but still pretty decent.

We don't encourage you to try anything like this, but based on the
evidence presented in this video experiment, it's not the worst thing
you could subject your electric vehicle to, although you will need
something quite powerful to do the towing.
