ABSTRACT： Automotive Industry Standards Commission AISC released draft AIS038 Rev.2 / D1 for electric vehicle power systems and AIS156 / D1 for electric two-wheelers power systems on September 30, 2019 for public comment. The last date for comments is ended on October 29, 2019. The new standard is purportedly released at the end of this year.
REGULATORY UPDATE BACKGROUND
The current regulation AIS048 is a test standard for power batteries used in M, N, and L vehicles. Issued in 2009, it has been revised several times. However, due to the rapid development of electric vehicles and power battery technology, some of the test items of the predecessor regulations could not fully adapt to the development of new technologies, so approved by the Ministry of Surface Transport (MoST), the Automotive Industry Standards Committee (AISC) initiated the regulatory revision process, publishing the draft regulation AIS038 and AIS156 to solicit opinions from all walks of life. The new draft regulation AIS038 is for power batteries used in passenger cars and commercial vehicles (M and N vehicles) and AIS156 is for power battery used in two-wheeled vehicles (type L vehicles), which are expected to be officially released by the end of this year.
BRIEF ANALYSIS OF NEW AND OLD REGULATIONS
Compared with the original regulation AIS048, the new draft regulations AIS038 / AIS156 have changed greatly in terms of regulatory framework, technical requirements, and test methods. The original regulation AIS048 only test at the cell, module, and battery pack level, and is without any environmental test items. The new regulations AIS038 / AIS156, however, are closer to EU standards, adding the environmental test items, in which the test objects are mainly the battery system or subsystem or even the entire vehicle. Besides, the puncture test, which is most concerned by electric vehicle manufacturers and power battery manufacturers, will be removed.
1. Brief Analysis of AIS038 Rev.2/D1
The regulatory framework of AIS038 Rev.2/D1 refers to the UNECE R100 Rev. 3 draft, and the technical requirements and test methods are completely equivalent to UN GTR 20 Phase 1. The cell or module level puncture test in the original AIS048 regulation will be removed. Shock test (SOC 100%) will be replaced with Mechanical shock (SOC 95%). It is important to note that the technical requirements and test methods of AIS038 is more severe than the current UNECE R100 Rev.2. For example, in vibration test, temperature shock, simulated impact, and squeeze test, the initial test condition SOC in ECE R100 Rev.2 only shall be adjusted to a value in the upper 50%, but in AIS038 (and UN GTR 20), the SOC need to be adjusted to a value in not less than 95%.
2. Brief Analysis of AIS156/D1
The draft new AIS156 regulation framework is a complete copy of UNECE R136, and its technical requirements and test methods are also completely equivalent. It is worth mentioning that the original AIS048 puncture test will be removed, and the initial test conditions SOC for the vibration test and mechanical shock which shall be 100% before will only be adjusted to a value in the upper 50%.
The expert in ATIC has compiled the new and old regulations of India's power battery testing items as follows:
INTERPRETATION OF ENFORCEMENT DATE AND ATIC EXPERTS SUGGESTIONS
Once the regulation AIS038 and AIS156 are officially issued, there will be a transitional period. Manufacturers of power batteries and electric vehicles will have two options. One is to apply for certification directly in accordance with the new regulations AIS038 or AIS 156; the other is to choose to apply for certification in accordance with the original regulations AIS048, but once the transition period ends, AIS048 will be invalidated. Manufacturers with AIS048 certificate need to perform re-testing for compliance to the new regulations.
Based on the comparison of the above test items and the implementation provisions, it is recommended by ATIC expert that OEMs / manufacturers who plan to conduct M, N, and L type electric vehicle certification and power battery certification should perform certification according to AIS038 or AIS156.
ATIC PROVIDES ONE-STOP CMVR CERTIFICATION SERVICE
ATIC, as the designated technical service organization of ARAI of the Indian Automobile Research Institute, provides one-stop Indian CMVR certification for domestic manufacturers. The mandatory vehicle certification scope of the CMVR regulations includes: electric vehicle BOV, two-wheel and three-wheel vehicles, four-wheel passenger vehicles and trucks (M1, N1), light and heavy commercial vehicles (M2, M3, N2, N3), diesel/gasoline generator sets, etc. And safety-related components are also required to be certified in the CMVR regulations, including: power batteries, on-board positioning system with emergency call button, safety glass, brake hose, horn, tire, seat belts, hubs, lighting and signaling devices, retroreflectors, triangular warning signs, reflective strips, replaceable LED light sources, child seats Brake pads, helmets, seats and headrests, wiper blades, etc.
