Electric Vehicle Gear System Properties. We present a new method to predict the power losses in electric vehicle (ev) transmission systems using a thermally coupled gearbox efficiency model. And as there is just one gear regulating the electric motor, it means that evs don't even have a reverse gear!
Gear fault diagnosis for vehicle electric drive systems based on stator currents. Just about all vehicles have gears of some sort, as it’s far more efficient and controllable than a direct drive from the engine or motor.
