Safety compliance is paramount in lithium battery manufacturing. With the implementation of Phase 1 and Phase 2 requirements under AIS-156 and AIS-038 standards, Indian manufacturers have established world-class testing benchmarks.
Core Testing Requirements under AIS-156
The standard mandates strict electrical, mechanical, and environmental stress testing for traction battery packs:
- Thermal Propagation & Ingress: Strict requirements to contain thermal runaway within a single cell cluster without propagating across adjacent modules. Minimum IP67 water and dust ingress protection.
- Overcharge & Over-discharge Protection: Redundant secondary protection circuits independent of software BMS firmware.
- Mechanical Vibration & Drop Resistance: Rigorous vibration profiles simulating harsh road conditions across urban and rural transport terrains.
Ensuring BIS Cell Traceability
Every imported or domestically sourced cylindrical (e.g., 21700, 32700) or prismatic cell must carry a valid Bureau of Indian Standards (BIS) R-number under IS 16046 (Part 2): 2018. Buyers must verify that the cell test certificates correspond directly with the manufacturer batch numbers.
