Brief: With the development of the electric vehicle industry, the safety of automotive traction batteries has received increasing attention from regulators and the market. Various international organizations or countries have put forward different technical requirements and conformity assessment methods for automotive traction batteries. In addition to mandatory regulations or standards, a large number of corresponding industry / association standards have also appeared. ATIC has launched a global certification solution program for automotive traction batteries. We researched mandatory certification requirements and common industry certification requirements for mainstream countries / regions for automotive traction batteries, and summarized the traction battery testing framework (mechanical testing, environmental testing, electrical testing), and certification types in this article.
GLOBAL CERTIFICATION SOLUTION
Based on the multi-country certification experience that has served a large number of automotive traction battery manufacturers in recent years, ATIC has sorted out the global certification matrix for power batteries as follows：
Note：Countries or regions not included in the matrix currently have no special regulations and independent certification requirements for automotive traction battery)
TEST FRAMEWORK OF DIFFERENT CERTIFICATION
A BRIEF ANALYSIS OF NATIONAL CERTIFICATION IS AS FOLLOWS
EU: E-Mark certification, is compulsory certification for helmet and visors according to UNECE Regulation No. 22. Besides several testing for helmet such as construction, test for projections and surface friction, external projection, impact absorption, rigidity, retention system, material; there are also many testing for visors, including visor maneuvering, angle opening, field of vision, luminous transmittance, light diffusion, recognition of signal lights, spectral transmittance, refractive power, mist retardant visor, mechanical characteristics, optical quality and scratch resistance, and must label the conspicuity marking.
EU: E-mark certificates for automotive traction batteries are recognized in many countries and regions, and the corresponding technical regulations are UNECE R100-Part II. UNECE R100-Part II is applicable for traction battery systems (REESS) of electrically driven M and N vehicles. E-mark certification of traction batteries requires the sample preparation of at least 4 battery packs or modules (determined based on battery configuration), 3 sets of BMS and related accessories. ATIC can provide customers with E24, E49, E57 certificates of R100.2-Part II for electric vehicle traction batteries, with a certification period of 6 to 10 weeks.
China: In order to better regulate the safety of electric vehicles, the Standard Working Group on Electric Vehicle Traction Battery Standards organized by the Electric Vehicle Sub-Technical Committee of the Automobile Standardization Committee of China began drafting GB (Compulsory Chinese National Standards) for electric vehicle traction batteries in 2016. The GB drafting project number is 20160967-Q-339, the GB number has not been announced. The draft for the GB has been approved by the Chinse State Council and submitted to the WTO for review. The GB is planned to be implemented from July 1, 2020. The name of the new GB is The safety requirements for lithium-ion traction batteries for electric vehicles. It will replace GB / T 31467.3-2015 and GB / T 31485-2015 after official release. For vehicles/traction batteries applying for new type approval, the GB will be implemented from the date of release. For vehicles/traction that have obtained type approval before, the GB will be implemented after 13 months from the date of release of the new standard.
CMVR certification in India: AIS038 Rev2, the upcoming electric vehicle traction system regulation in India, will replace AIS048. AIS038 Rev2 deletes the roll-over test and penetration test in AIS048. All technical requirements and test methods in AIS038 Rev2 are coordinated with UN GTR 20 phase 1. AIS038 Rev2 is expected to be officially released and implemented at the end of 2019. Automotive traction battery manufacturers can begin to apply for India's AIS038 Rev2 certification after the regulations are officially implemented.
U.S.A automotive traction battery certification: In the federal motor vehicle safety standards FMVSS, there are no specific mandatory regulatory requirements applicable to electric vehicle traction batteries. For traction batteries which plan to enter U.S.A market, there are mainly industry or association certifications such as SAE standard testing and UL certification.
UN38.3 Transport of Dangerous Goods: Chapter 38.3 of the United Nations Recommendations on the Transport of Dangerous Goods- Manual of Tests and Criteria (referred to as UN38.3) indicates detailed provisions for of metal lithium and lithium ion battery packs transport. UN38.3 test simulates transportation conditions, such as thermal test, vibration test, forced-discharge etc., namely T1 to T8 test, respectively. Automotive lithium-ion traction batteries require UN38.3 tests report and certificate at cell and module levels.
