A larger vehicle parc also increases demand for post-market failure analysis and warranty-related investigation.
India’s broader electric vehicle testing, inspection, and certification economy was estimated at around USD 36 million in 2023 and is assessed to approach USD 126 million by 2030, expanding at close to 19% each year. The thermal safety testing and certification segment forms a defined and fast-expanding fraction of this economy, owing to the mandatory nature of thermal propagation and abuse testing. Transportation applications account for the majority of national battery testing-inspection-certification spending, with electric two-wheeler and three-wheeler packs concentrating cell-level and pack-level test requirements. The global electric vehicle battery testing market provides directional context, assessed at around USD 4 billion in 2025 and close to USD 9 billion by 2030.
National safety standards form the structural foundation of the market. AIS-156 and AIS-038 Revision 2 were strengthened through Amendment 3, implemented in two phases on 1 December 2022 and 31 March 2023, as set out in amendments notified by the Ministry of Road Transport and Highways. The amendments added requirements covering battery cells, management systems, chargers, pack design, and thermal propagation arising from internal cell short circuit. Traction battery cells must comply with IS 16893 Part 2 and Part 3, while complete modules and packs follow AIS-156 or AIS-038 Revision 2 according to vehicle category.
Phase 1 requirements, effective from 1 December 2022, covered pack traceability, additional safety fuses, protection against regenerative braking, cell-to-cell spacing, and microprocessor-based management systems. Phase 2 requirements, effective from 31 March 2023, added earth-leakage detection on chargers, electromagnetic compatibility testing of management systems, cell testing from accredited laboratories, thermal propagation testing, audio-visual warning during a thermal event, four temperature sensors, and active parallel circuits. The phased structure made battery safety validation a recurring requirement across the industry. The earlier AIS-048 standard was withdrawn, consolidating safety validation under AIS-156 and AIS-038 Revision 2.
