新能源汽车上海地方法规涉水检测经验浅析

The Experience of New Energy Vehicles Wading Test According to Shanghai Local Regulations

对新能源汽车上海地方法规涉水试验部分进行解读,转换成可操作的试验指南。使用该指南分别在工厂和上海地标指定涉水池进行试验,排查了几个典型的车身密封问题点,另外发现涉水池尺寸差异会产生不同的试验结果。调整工厂涉水试验工况,提出匹配上海地方法规试验的试验指南,提高车身孔隙防水设计的离地最小高度界限要求,确保异地涉水池中的新车开发验证工作也能完全满足上海地方法规试验要求。

Analysis the wading test requirement of Shanghai local regulations and convert it to operable guidelines.Do the wading test both in factory pool and shanghai local designated-pool by the guidelines.Settle several typical leakage issues and find that wading pool with different size may cause different leaking result.Propose adjusted guidelines and more strictly holes-sealing requirement to ensure the new energy vehicle can meet the requirement of Shanghai local regulations.
