How to charge a Tesla Model 3 with a tow rope
Instant torque makes EVs quite powerful towing machines. But what is it like the other way round? This is a physics lesson that's actually fun.
TechForum published a video on YouTube where a Tesla Model 3 gets towed and has its energy consumption and range monitored. The result is, unsurprisingly, that the Tesla displays a range analogous to infinite during towing, while the towing vehicle's consumption increases. But beside seeing physical laws of energy transfer working, in the end, the batteries were charged while not being chained to a stationary charging point.
The regenerative braking system works like a dynamo. Energy is used to turn the generator which then charges the Tesla's batteries. In the video, this energy comes from a Ford C-Max hybrid, while a considerable amount of the afforded energy is lost due to friction and heat production.
Now, what to do with this information?
If you own a Tesla and you need some recharging, but you do not have time to wait at a charging point, call a friend with a tow hitch on his or her car. If you get towed half the way, the odds are in your favour, that you can drive the other half of your way on your own.
