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 charging piles, electric energy metering and safety concerns 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.
noa can provide you with professional charging pile testing, including technical analysis report of periodic testing, protocol consistency test, interoperability test, charging pile energy metering and other technical service solutions.

(1) because the charging pile standards are too messy to take account of the market models, and the charging process is often interrupted or unable to charge, the user experience is poor. the quality of the charging pile brand is disorderly, which brings potential safety hazards to users;
(2) most of the charging piles are built in public places, and the public safety can be guaranteed through the testing of the charging posts of the trams;
(3) it can improve the quality of the charging pile;
(4) doing a good job of charging pile inspection can promote our new energy vehicles in the international position, and also consolidate our test capability for new energy vehicles.
in the following cases, the product must undergo type test:
(1) the type test shall be carried out for the newly put into production products (including the products produced in other factories) before the production appraisal;
(2) when design change, process or main components change and affect product performance, type test shall be conducted before production;
(3) type test shall be carried out for products that have been out of production for more than two years before being put into production again.
