the new energy vehicle industry is a strategic emerging industry. the development of new energy vehicles is an effective measure to promote energy conservation and emission reduction. pure electric vehicles can achieve zero pollution in the operation process. the development of the automobile industry not only brings opportunities and vitality to the social economy, but also brings convenience to people's daily travel. cars are changing our lives, but also viciously changing our environment, energy conservation and environmental protection of automobiles are urgent problems to be solved at present.
with the enhancement of people's awareness of environmental protection, pure electric vehicles are increasingly replacing petroleum energy vehicles in major cities as a new generation of transportation tools. but for new energy vehicles, the biggest obstacle is infrastructure construction, price and site constraints. compared with hybrid electric vehicles, electric vehicles need more supporting infrastructure, such as charging facilities in residential areas, highway service areas or large public places.
with the large-scale construction and application of charging stations, the interconnection of vehicle piles, electric energy metering and safety problems are increasingly apparent. electric vehicle charging station (pile) products are still in the early stage of development, and most of the products in the industry are in the transition period of new and old standards. the electric vehicle charging station (pile) has potential safety hazards in terms of charging safety, electrical performance indicators, pile compatibility, interoperability of charging stations (piles), etc. it is urgent to carry out relevant inspection and quality evaluation.
