- A Pot-box or potentiometer box is the device which will physically connect to your accelerator pedal through the accelerator pedal cable. It provides a spring-loaded arm which can be activated by stepping on the accelerator pedal allowing more or less current through to the motor controller and tells the motor controller simply how much capacity to send for the motor for acceleration.
- A relay is a device which utilizes a small control voltage for example 12 volts, to manage a bigger system voltage including 120 volts. A relay (non solid state) features a magnetic coil that if activated pulls a couple of contacts closed and allows current to circulate around the larger voltage side from the relay. It is then possible to have smaller control wires on the key change to operate the car plus a safe voltage inside the cab with the electric vehicle. Relays would typically be used to control some of the high voltage systems of the vehicle including the main contactor or heater core.
- An inertia switch is a security switch designed to cut chance to the car should it be involved in an accident. It really is typically mounted nearby the front from the vehicle when impact occurs the shaking from the inertia switch releases a magnetically held group of contacts shutting off of the capacity to the car. In certain countries it is a requirement for any electric vehicle conversion.
