An overview on various sources of vibration in electric vehicle and their identification techniques

In recent years, the demand for electric vehicles in the market has increased in an era of technological progress aimed at zero emissions to the environment. It explored the tremendous range of improvements for electric vehicles from a technical and commercial perspective. However, these electrification trends have revealed various problems associated with them. Above all, ride comfort and vehicle durability are very important concerns for users. Vehicle-specific vibration noise has a significant impact on ride comfort and battery life. This white paper provides an overview of noise and vibration analysis for electric vehicles. The first and most important introductory section provides an outlook on the growing demand for electric vehicles and the rapidly growing market and types of electric vehicles. The second section provides an overview of EV noise and vibration sources and a review of the supporting literature. In the third section, we will look at different techniques for vibration sources. From traditional techniques to cutting-edge techniques. Finally, we draw overarching conclusions along with some future research areas.
