“汽车发动机在出厂时产品检测一定是符合标准的,那么为什么还需要年检呢?原因就在于发动机性能会逐年出现下降。新能源汽车也存在同样的问题,其中最关键的零部件——电池的安全性能也会发生变化。”UL全球汽车工业部门总工程师李小攀说,“这就是为什么,业内呼吁要尽快出台新能源汽车年检标准。” “The car engine at the factory product testing must be in line with the standard, then why do you need annual inspection? The reason is that the engine performance will decline year after year.New energy vehicles have the same problem, one of the most critical components - the battery Safety performance will change. ”UL Global Automotive Industry Chief Engineer Li Xiaopan said, “ This is why, the industry called for the introduction of new energy vehicles as soon as possible annual inspection standards. ”
