It might be an EV with an electric motor but it is not like the motor on your woodworking machinery where you just turn the power on/off . These motors are three phase and driven by complex invertors using forms of vector control. You need to know the position of the rotor so you have position sensors, you need to know the stator currents so that you can control the torque as part of a three term control loop and will be monitoring temperature as a protective measure. You will also have a pedal sensor so the control system knows what speed you are requesting, sensors for battery management and charging, sensors that monitor the temperature of power switches in the drive controler, others to monitor transmission temperature and then you will have others that work in the regenerative braking system in conjunction with the ABS. You will also have sensors carried over from the ICE vehicle such as impact sensors to trigger airbags.
