Safety is the non-negotiable bedrock of the electric vehicle revolution. This standard represents the critical safety baseline for secondary lithium-ion cells used in EV propulsion. It rigorously evaluates how a cell behaves under “reasonably foreseeable misuse”—ensuring that a minor accident or system failure doesn’t escalate into a catastrophic thermal event. Compliance here is not just about meeting a regulation; it is about guaranteeing the structural and chemical integrity of the power source that drives modern mobility.

This testing regime is designed specifically for Secondary Lithium-Ion Cells and Cell Blocks intended for the propulsion of electric road vehicles. It covers:
To ensure a cell is robust enough for automotive use, it must withstand a gauntlet of mechanical, electrical, and thermal abuse tests without rupturing or igniting.
Standard testing cycles for IS 16893 Part 3 typically range from 12 to 18 working days.
To complete the full suite of destructive and non-destructive tests, the laboratory generally requires:
Note: The exact number depends on whether the lab runs parallel testing streams to save time. Always provide samples from the same manufacturing lot to ensure consistent data.
Pricing for this standard is highly variable based on cell capacity (Ah) and current lab load.
To initiate the project and ensure the final test report is valid for certification, the following documents are mandatory:
Yes, it is a critical safety requirement for lithium-ion cells used in electric vehicles. Compliance is often a prerequisite for obtaining final battery pack certification under AIS standards.
Part 2 focuses on reliability and abuse testing for data gathering, while Part 3 establishes strict safety acceptance criteria to ensure the cell does not endanger passengers during failure.
No, this standard specifically covers individual secondary lithium-ion cells and cell blocks. The complete battery pack must be tested separately under standards like AIS-156 or AIS-038.
Generally, no. For Indian regulatory compliance (like BIS or AIS), test reports must typically be issued by an NABL-accredited laboratory located in India or a BIS-recognized lab.
If a cell ruptures or catches fire, it fails the safety criteria. You must modify the cell's design or internal chemistry and submit new samples for re-testing.
Test reports do not strictly expire, but they are valid only for the specific cell model tested. Any change in cell construction, chemistry, or capacity requires fresh testing.
