Noise Analysis of Electric Drive Assembly of 800 V High Voltage Platform of Electric Vehicle
At present,the voltage range of the high-voltage electrical system of mainstream new energy vehicles is generally 230～450 V,and the middle value is called the 400 V platform.With the application of fast charge and supercharge,the voltage range of automotive high voltage electrical system reaches 550～930 V,and the middle value is called 800 V platform.Based on the background of noise analysis and optimization of 400 V and 800V battery systems for a front-drive pure electric model equipped with 800 V electric drive assembly,this paper carried out theoretical analysis through subjective and objective data,and optimized the electric drive assembly body and vehicle transmission path to improve the interior noise.This has important guiding significance and engineering value for the NVH performance development of the subsequent vehicle equipped with 800 V platform electric drive assembly.
