Charging Pile Type Test-NOA Testing & Certification Group

Charging Pile Type Test

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.

Service Process

Q&A

What testing items need to be done to apply for subsidies?

Generally, the acceptance shall be carried out according to the acceptance requirements of the local government. If there are no special requirements, it is recommended to carry out inspection and testing according to the requirements of national standards, such as GB 50966-2014 Code for design of electric vehicle charging station, NB/T 33004-2013 Code for construction and completion acceptance of electric vehicle charging/battery swap infrastructure, and other standards. NOA has the ability to conduct full inspection and testing, and has the relevant qualifications of CMA and CNAS, Customized services can be provided according to customer requirements to solve the worries behind.

According to which standards are charging piles generally tested?

According to NB/T 33001-2010 Specification for electric vehicle off-board conductive charger, NB/T 33002-2010 Specification for electric vehicle A.C charging point, NB/T 33008.1-2018 Inspection and test specifications for electric vehicle charging equipment Part 1: off-board charger, NB/T 33008.2-2018 Inspection and test specifications for electric vehicle charging equipment Part 2: A.C. charging spot, GB/T 34657.1-2017 Interoperability test specifications of electric vehicle conductive charging—Part 1:Supply equipment, GB/T 34658-2017 Conformance test for communication protocols between off-board conductive charger and battery management system for electric vehicle, JJG 1148-2018 AC Charging Spot for Electric Vehicles, JJG 1149-2018 Off-board Charger for Electric Vehicles, etc.

Why do charging pile stations need to be tested?

(1) Because the charging pile standards are messy and can't 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 posts 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 detection can promote our new energy vehicles in the international position, and also consolidate our test capability for new energy vehicles.

Under what circumstances is type test required?

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.
