Brief: According to the latest notification by the Indian Ministry of Road Transport and Highways, AIS 038 Revision 2 Amendment 3, the standard of traction battery (REESS), has been officially implemented since March 31, 2023. Besides, traction battery (REESS) is officially included in the safety criticalcomponents, and its type approval and conformity of production need to be verified by the Indian official agencies.
August 29, 2022, the Automotive Industry Standards Committee issued Amendment 2 to the AIS 038 Revision 2. Then, September 27, 2022, the Indian Ministry of Road Transport and Highways updated the government notification and introduced Amendment 3 to the AIS 038 Revision 2, which detailed therequirements of Amendment 2and changed the implementation date into two phases: December 1, 2022 and March 31, 2023.
From December 1, 2022, the following additional requirements have been into force.
Requirements for charge-discharge cycle for cells
Pressure release vent in REESS design
The arrangement of the cells
REESS short-circuit protection design
BMS circuit features
Satety feature verification for BMS
Requirements for onboard/portable charger
Traceability of the REESS and components
Kinetic energy recovery design
Critical parameters logging in the BMS
From March 31, 2023, the following additional requirements have been into force.
Establishing conformity of production
According to AIS038 Rev.2 Amd.3:
⇨ Factory audit and CoP surveillance, need to refer to the requirements of the AIS 037.
