Abstract

NVH, which stands for noise, vibration, and harshness, typically ranks within the top five attributes in terms of priority during the design phase of automotive vehicles. As electric vehicles become increasingly prevalent in modern transportation, the management of Noise, Vibration, and Harshness (NVH) has emerged as a critical aspect of vehicle design and refinement. This review paper aims to provide a thorough examination of the NVH sources within EV powertrains and their respective contributions to the overall noise emitted by electric vehicles. Each NVH source is analyzed in terms of its underlying mechanisms, frequency spectra, and methods for quantification and characterization. By synthesizing existing literature, industry insights, and technological advancements, this review primarily aims to enhance the understanding of NVH challenges in electric propulsion systems and facilitate the development of quieter and more refined electric vehicles.
