Why is single gear transmission used in electric cars?

The transmission components are essential for the internal working if an engine. But do you know why electric vehicles are equipped with a single gear transmission? Here’s your answer.

Mostly electric cars come with single speed transmission while the counterpart has a gearbox with multiple speed ratio. As we all know that the electric motor delivers maximum torque at zero rotation per minute. So it doesn’t need a special component to disengage it from the drive train in order to achieve ideal condition.

Unlike an internal combustion engine, electric motors have a wide range of rpm and are capable to provide its optimum power output at this range. So there is no need to provide a variety of gears to keep the engine in its effective zone. Thus the electric car designers pic an optimum gear ratio that will supply a balance between its top speed and acceleration. The electric motors are capable to attain an rpm of 20,000, so the top speed can’t be constrained.

In short, electric motors are capable to offer a wide range of speed which an internal combustion cannot achieve. This makes it possible for an electric car to provide required results with a single transmission and reduces transmission components for the vehicle.
