Interior noise of A battery electric vehicle in high speed is studied in this paper. From the per-spective of practical engineering application, the interior sound pressure level (SPL) of the electric vehicle under the working condition of 30m/s is analyzed based on the Corcos model, the Diffuse Acoustic Field (DAF) model, the boundary element method(BEM) and the statisti-cal energy analysis(SEA) method. The accuracy of the methods was verified by comparison with the experiment. The influence of different thickness of side window glass on the SPL of the driver's head cavity is analyzed, which can guide the design of body material parameters and sound package.
