basic introduction

New energy vehicles refer to the use of unconventional vehicle fuel as the source of power (or the use of conventional vehicle fuel and the use of new on-board power devices), and the integration of advanced technology in vehicle power control and driving, resulting in advanced technical principles and new technologies , The new structure of the car.

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-powered vehicles, hybrid vehicles (oil-gas hybrid, oil-electric hybrid) Solar vehicles and other new energy (such as high-efficiency energy storage) vehicles have relatively low emissions.

As of the end of 2010, the number of natural gas vehicles in the world had exceeded 12.67 million, and there were more than 18,200 natural gas filling stations. China's natural gas vehicles are developing rapidly. Among them, LNG (liquefied natural gas) vehicles are growing at an average annual sales rate of more than 20%, and CNG (compressed natural gas) vehicles are growing at an average annual growth rate of more than 30%.

In addition to the detection indicators of ordinary cars, the quality certification of new energy vehicles also has some specific detection standards, such as: defrosting of electric vehicles, demisting of electric vehicles, graphic signs of electric vehicles, safety technical requirements of fuel cell electric vehicles, and electromagnetic radiation intensity , The performance of lithium-ion batteries for electric vehicles, the performance of lead-acid batteries for electric vehicles, and the safety requirements for electric vehicles total 11 items.
