Electric Car Control System

The controller takes in 144 volts dc and delivers it to the motor in a controlled way.

Electric car control system. The throttle position and the break is the input to the control system. Types of ecu include engine control module ecm powertrain control module pcm transmission control module tcm brake control module bcm or ebcm central control module ccm central timing module ctm general electronic. In this video segment we show how to connect the motor speed controller and throttle. Fitting a radio with the incorrect polarity will damage the set but most car radios have an external switch for setting the polarity to suit that of the car.

In control of electric vehicle the control obje ctive is the torque of the driving machine. Let s assume that the battery pack contains 12 12 volt batteries wired in series to create 144 volts. The very simplest dc controller would be a big on off switch wired to the accelerator pedal. This is called a negative earth system and when buying an electrical accessory a radio for example check that it is of a type suitable for your car s system.

With the use of our sophisticated electronic driving systems many people can assume the responsibility of driving for themselves again. An electronic control unit ecu is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a vehicle. Electric vehicle is dependent on many factors such as the intention of the ev ease of control etc. The controller s job in a dc electric car is easy to understand.
