燃料电池汽车碰撞后氢安全检测方法研究综述

A Review of Post-Crash Hydrogen Safety Detection Methods for Fuel Cell Vehicles

随着国家对氢燃料电池电动汽车的支持力度加大,国内已有多家企业及科研机构开展燃料电池汽车的研发,很多车型也获得了国家公告。但是由于目前国标体系中缺少燃料电池电动汽车碰撞后氢安全检测相关的标准,各家企业在进行燃料电池汽车碰撞试验时会制定自己的检验方案及技术要求,存在标准不统一。对比分析了国外标准对燃料电池电动汽车碰撞后的氢安全检测的方法及要求,并对碰撞方案给出相关建议,为国内开展燃料电池汽车碰撞研究提供参考。

With the increase of national support for hydrogen fuel cell electric vehicles,many domestic enterprises and research institutions have carried out research and development of fuel cell vehicles,and many models have received national announcements.However,due to the lack of standards related to post-crash hydrogen safety testing of fuel cell electric vehicles in the current national standards system,each enterprise will develop its own inspection scheme and technical requirements when conducting fuel cell vehicle crash tests,and there are inconsistent standards.This paper compares and analyses the methods and requirements of foreign standards for post-crash hydrogen safety testing of fuel cell electric vehicles,and gives relevant recommendations on the crash protocols to provide reference for domestic research on fuel cell vehicle crashes.
