Not the Cybertruck story, but perhaps more important.
The Justice Department has been probing Tesla for their exaggerated range claims, and suddenly Tesla has decided to reduce their estimates on these already-released cars.
I didn’t think you’d be able to push an EV. Do Tesla’s have some sort of tow or neutral mode?
Dunno but he did it while his girlfriend steered. It is a model Y. He’s a big guy who works out. He said it took everything in him to get it over a tiny hill at the exit ramp.
“Neutral” on an EV doesn’t mean the same thing as on a IC car. The motors are still physically connected to the wheel, so turning the wheels will create an electric current.
That current will flow into the batteries from the “wrong end”. Normally, charge controllers and battery management systems will ensure every cell of battery gets a balanced charge, but those systems don’t work when you tow or push an EV. You can end up ruining the battery. Another issue is that power and friction cause heat, and when the car isn’t running, that might cause overheating.
Now, the good news is that you’re very unlikely to push an electric car fast enough or far enough for either of those to become a real issue. Electric cars are still big and heavy.
Yeah that’s what I thought. So not only are you fighting the usual weight and friction, but also resistance from the motors.
