Electric Car Controller? Why You Need One



Electric Car Controller...

Controllers are electronic power control devices that regulate the DC voltage supplied by the batteries to the motor...

Usually done by "chopping" the DC current up to give a different duty cycle...

This is called Pulse width modulation, and is done at a very high frequency, outside of normal hearing range...

If your DC voltage from your battery pack is 96 volts, then the controller pulses the power supplied to the DC motor...



Pulses are supplied in different amounts, at high frequency according to the position of your accelerator pedal.

Effectively, it divides the time that the motor is on versus the off time to give a smooth adjustment of the dc voltage according to the throttle or accelerator pedals position.

This means that you can have the effect or feel, of a gasoline engine's variability in revolutions but with the major benefit of the high torque of an electric motor...

The accelerator pedal is made of optical potentiometers or variable resistors that allows the smooth adjustment of speed to take place...
