Additional safety requirements recommended in the existing Electric Vehicle Battery Safety Standards (AIS-156 & AIS-038) with effect from 1st October 2022

Posted On: 01 SEP 2022 7:25PM by PIB Delhi

In the backdrop of number of cases of fire incidents observed in electric two wheelers in different parts of the country, Ministry of Road Transport and Highway had constituted an Expert Committee, Chaired by Shri Tata Narsingh Rao (Director, ARC’, Hyderabad), and Shri M.K. Jain (Scientist – G, CFEES, DRDO), Dr. Arti Bhatt (Scientist-F, Additional Director, CFEES, DRDO), Dr. Subba Reddy (Principal Research Scientist, IISc, Bengaluru), Prof. L Umanand (Chair, DESE, IISc, Bangaluru), Dr. M. Srinivas (Scientis-E, NSTL, Vishakhapatnam), Prof. Devendra Jalihal (Head, C-BEEV, 11T Madras, Chennai) as members, to recommend additional safety requirements in the existing battery safety standards notified under CMV Rules.

Based on the recommendations of the expert committee report, the Ministry, on 29th August 2022, has issued amendment 2 to AIS 156- Specific requirements for motor vehicles of L category [motor vehicles with less than four wheels and is a quadricycle] with electric power train, and amendment 2 to AIS 038 Rev. 2 – Specific requirements for Electric Power Train of motor vehicles of M category [motor vehicle with at least four wheels used for carrying passengers] and N category [motor vehicle with at least four wheels used for carrying goods which may also carry persons in addition to the goods]. These amendments include additional safety requirements related to battery cells, BMS, on-board charger, design of battery pack, thermal propagation due to internal cell short circuit leading to fire etc.

The notification to mandate amended AIS 156 and AIS 038 Rev.2 standards for the respective categories of electric vehicles with effect from 1 st October 2022 is in progress.

Ministry also has issued draft notification GSR 659 (E) dated 25th August 2022, to amend Sub-rule 4 of Rule 124 of Central Motor Vehicles Rule (CMVR) 1989, for mandating Conformity of Production (COP) for traction batteries used in electric power train vehicles. The proposed regulation will be applicable with effect from 1st October, 2022. Comments and suggestions have been solicited from all stakeholders within a period of thirty days.

BIS formulates performance standards for Electric Vehicle Batteries

BIS in the process of publishing two more standard related to batteries for various passenger and goods carrying vehicles.

Bureau of Indian Standard, National Standard Body of India, has published standards for Test Specifications for Lithium-ion Traction Battery Packs and Systems (Performance Testing) for Electrically Propelled Road Vehicles. The standard IS 17855: 2022 for these battery packs and systems is harmonized with ISO 12405-4: 2018. 

This standard incorporates the test procedure for basic characteristic of performance, reliability and electrical functionality for the battery packs and system for either high power or high energy application. This standard is formulated considering real life scenarios for an electric vehicle such as vehicle is in parking (battery is not used for extended period of time), battery system is being shipped (stored), operating battery at low and high temperature etc., accordingly various tests are incorporated in this standard.

Safety and performance are two critical aspects of electronic devices. Requirement of Battery system for use as a power source for propulsion of vehicles are significantly different from battery used for consumer electronics or stationary use.

Electric vehicles are vehicles that operate on electric motor and rechargeable batteries. Over the past decade, Electric vehicles have grown in terms of visibility and availability in the market. For safety of consumer, reliability and safety, Energy storage systems become critical part of any EV. Most of the EVs use Lithium-ion batteries because of its high power to weight ratio.

Further, keeping view on safety aspect of batteries for EV, Bureau of Indian Standard is in the process of publishing 2 more standard related to batteries for various passenger and goods carrying vehicles (L, M and N category)
