Brief: India Automotive Industry Standards Commission AISC released draft AIS-038 Rev.2 / D1 for electric vehicle power systems and AIS-156 / D1 for electric two-wheelers power systems on September 30, 2019 for public comment and it is expired on October 29, 2019. Recently, ATIC had completed Indian AIS-038 electric vehicle traction battery test witness for several top manufacturers domestically. These manufacturers were the firsts to test since this standard was released, and would obtain the certification report soon.
The previous regulation AIS-048 included test methods for power batteries used in M, N, and L category vehicles. I had been revised several times since firstly issued in 2009. However, due to the rapid development of electric vehicles and traction battery technology, some of the test items of the predecessor regulations could not fully adapt to the development of new technologies. Thus approved by the Ministry of Surface Transport (MoST), the Automotive Industry Standards Committee (AISC) initiated the regulatory revision process, and published the draft regulations of AIS-038 and AIS-156. The new regulation AIS-038 subjected to traction batteries used in passenger cars and commercial vehicles (M and N vehicles) and AIS156 subjected to traction battery used in two-wheeled vehicles (type L vehicles).
BRIEF ANALYSIS OF NEW AND OLD REGULATIONS
Compared with the previous regulation AIS-048, the new regulations AIS038 / AlS156 were changed greatly in terms of regulatory framework, technical requirements, and test methods. The previous regulation AIS-048 could test at the cell, module, and battery pack levels, and no environmental test item was included. The new regulations AIS-038 / AIS-156 got closer to EU standards, and were added with environmental tests and thermal propagation. Test objects became mainly the battery system, subsystem and even the entire vehicle. Besides, nail penetration was removed which was the most concerning test item before.
BRIEF ANALYSIS OF AIS038 REV.2/D1
The regulatory framework of AIS038 refered to UNECE R100 Rev. 3 draft, test methods were completely equivalent to UN GTR 20 Phase 1, but technical requirements were unique. Nail penetration test at cell / module level in the AIS-048 was removed. Shock test (SOC 100%) was replaced by mechanical shock (SOC 95%). To be noted that the technical requirements and test methods of AIS-038 was more strict than the current UNECE R100 Rev.2. Such in vibration test, thermal shock, mechanical shock, and mechanical integrity, the initial condition in ECE R100 Rev.2 only should be high than 50% SOC, but in AIS-038, the SOC should be not less than 95%. Compare with China GB 38031-2020 which also refered framework of GTR 20, the AIS-038 was less strict in test methods and less test items, but more strict in initial conditions and after test requirements.
