Condition Monitoring and Fault Diagnosis of Induction Motor in Electric Vehicle

The twenty-first century is witnessing the growth of electric vehicles due to the declining level of petroleum products and legal concern for clean technology to take care of environmental pollution. Battery and electric motor are the two important components in the electric vehicle. An electric motor is a prime component responsible for the propulsion of a vehicle. Because of the continuous operation and load variation, the motor is subjected to different types of faults. Thus, condition monitoring and on-board diagnosis of an electric motor in the electric vehicle is essential to avoid catastrophic failure. In India, it is observed that the induction motor is commonly used in electric vehicles for propulsion. This article proposes the methodology for condition monitoring and fault identification of components in the induction motor using an on-board diagnostics in an electric vehicle.
