    Application of electric vehicle motor controller

    Tips: What is the control system of an electric vehicle?

    The most complex and important system in an electric vehicle is the control system. The control system is responsible for managing the operation of the electric vehicle. The control system receives input from the operator, controller feedback signals from the motor controller and motor, and feedback signals from other systems within the EV. The control system must receive data from other systems in milliseconds, process the data algorithmically, and output a response to a given condition at a rate that is fast. This requires the control system to have a microprocessor, like a computer, to perform its tasks. Although no two control systems are exactly alike, most feedback signals are similar.
