Summary:

Electric vehicles (EVs) present a distinct set of challenges in noise, vibration, and harshness (NVH) compared to traditional internal combustion engine (ICE) vehicles. As EVs operate with significantly reduced engine noise, other sources of noise, such as motor whine, power electronics, and road and wind noise, become more noticeable. This review paper explores the key NVH issues faced by EVs, including high-frequency tonal noise from electric motors, gear meshing, and vibrations. Additionally, it examines recent advancements and trends in NVH mitigation techniques, such as active noise control, improved material insulation, and advanced vibration isolation systems. Furthermore, this paper discusses the role of computational tools, simulation technologies, and testing methodologies in predicting and addressing NVH concerns in EVs. By providing an in-depth analysis of the challenges and the latest innovations, this review aims to contribute to the ongoing development of quieter and more refined EVs.EVs pose unique challenges in the realm of noise, vibration, and harshness (NVH) that differ from those encountered in traditional internal combustion engine (ICE) vehicles. With the significant reduction in engine noise in EVs, other noise sourcessuch as motor whine, power electronics, and road and wind noisebecome more prominent. This review paper delves into the primary NVH challenges associated with EVs, including the high-frequency tonal noise produced by electric motors, gear meshing, and vibration issues. It also explores the latest advancements and trends in NVH mitigation techniques, such as active noise control, enhanced material insulation, and advanced vibration isolation systems. Additionally, the paper highlights the role of computational tools, simulation technologies, and testing methodologies in predicting and addressing NVH challenges in EVs. Through a comprehensive analysis of these challenges and innovations, this review aims to support the ongoing efforts to develop quieter and more refined EVs
