摘　　要：文章基于公司某纯电平台开发实践,梳理了全新纯电平台开发的必要输入、平台拓展策略以及需要重点考量的要素。通过布置方案对比得出了选型建议,结果表明:A型臂前置式麦弗逊悬架相对A型臂后置式麦弗逊悬架,可以获得更大的电池包布置空间;轴前电机布置+转向器前置的布置方案L113相对更小,可以改善乘员舱空间利用率;后电机采用轴后电机布置可以有效改善三排人体的脚步空间;空调箱相对传统横置空调,分体式空调箱和纵置空调箱有利于女王副驾的布置,但对前舱高压器件的布置存在不同程度的影响。Based on the development practice of a pure level station,this paper summarizes the necessary input,platform expansion strategy and key factors to be considered in the development of a new pure level station.The selection suggestions are obtained by comparing the layout scheme.The results show that the A-arm McPherson can obtain larger battery pack layout space than A-arm rear McPherson suspension.For the layout scheme L113 in front of the motor and steering gear layout shaft and the motor layout in front of the steering gear layout shaft,it is relatively smaller,which can improve the utilization rate of the crew cabin space.The rear motor of the rear motor arrangement can effectively improve the footstep space of three rows of human bodies;Compared with the traditional horizontal air conditioning box,split air conditioning box and longitudinal air conditioning box are conducive to the arrangement of the queen's first officer,but they have different degrees of influence on the arrangement of high voltage devices in the front cabin.
