New Energy Vehicle Product Certification
Basic Introduction
New energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures.
New energy vehicles include gas vehicles (liquefied natural gas, compressed natural gas), fuel cell electric vehicles (FCEV), pure electric vehicles (BEV), liquefied petroleum gas vehicles, hydrogen energy vehicles, hybrid vehicles (oil and gas hybrid, oil and electricity hybrid), solar vehicles, and other new energy vehicles (such as high-efficiency energy storage devices), etc., and their exhaust emissions are relatively low.
As of the end of 2010, the global natural gas vehicle ownership has exceeded 12.67 million vehicles, and the number of natural gas filling stations has exceeded 18,200. China's natural gas vehicles are developing rapidly, among which LNG (liquefied natural gas) vehicles are growing at an average annual sales rate of more than 20%, and CNG (compressed natural gas) vehicle sales are growing at an average annual sales rate of more than 30%.
In addition to the testing indicators for ordinary cars, the quality certification of new energy vehicles also has some specific testing standards, such as: electric vehicle defrosting, electric vehicle defogging, electric vehicle graphic signs, fuel cell electric vehicle safety technical requirements, electromagnetic radiation intensity, electric vehicle lithium-ion battery performance, electric vehicle lead-acid battery performance, electric vehicle safety requirements, etc., a total of 11 items.
