What are the specific testing items for new energy vehicles?

Dr. Cha learned about the following new energy vehicle inspection categories:

Gas vehicles (LNG, liquefied natural gas), fuel cell electric vehicles (FCEV), new energy vehicles ( BEV), compressed natural gas vehicles, hydrogen-powered vehicles, hybrid vehicles (oil-gas hybrid, petrol-electric hybrid) solar vehicles and other new energy technologies (such as effective energy storage) vehicles and vehicles, their exhaust emissions are very low.
