EV battery safety testing puts batteries through controlled electrical faults, heat exposure and mechanical stress to assess their response. Engineers also examine performance; surviving a safety test does not establish how much usable energy a battery delivers.
India has added testing capacity in Pune. In an October 31, 2026 announcement, the Ministry of Heavy Industries said H.D. Kumaraswamy virtually inaugurated the Automotive Research Association of India’s Advanced Battery Laboratory, supporting battery validation and certification for electric and hybrid vehicles.
Key Highlights
- The advanced battery laboratory represents an investment of approximately ₹55 crore
- Its remit covers safety assessment, performance evaluation and export compliance testing
- Additional advanced fire safety facilities remain planned developments
What ARAI’s New Laboratory Adds
The laboratory received support through the ministry’s Capital Goods Sector Phase II scheme. Alongside it, Kumaraswamy inaugurated a separate two-dynamometer facility for e-axles and EV powertrains. Battery evaluation and drivetrain evaluation address different parts of an EV’s operation.
The ministry’s battery-testing infrastructure programme identifies equipment for:
- Battery-pack fire, crush and short-circuit testing
- Vibration, mechanical shock and temperature exposure
- Battery cycling and gas analysis
Those are the programme’s listed capabilities. The inauguration release does not publish an equipment-by-equipment commissioning checklist, so it would be premature to describe every listed test as newly operational.
The safety concern extends beyond dramatic fire videos. In a February 10, 2026 parliamentary reply, the government reported 26 fire-involving EV road accidents recorded on eDAR during 2023–2025. It also said India lacked centralised data specifically tracking all battery-fire incidents. That figure therefore cannot establish the country’s total EV battery fires or an overall fire rate.
How EV Battery Safety Testing Examines Failure
A cell may enter thermal runaway, a rapid, self-heating reaction. The next question is whether the failure spreads through the battery and exposes occupants or bystanders to fire.
India’s AIS-156 amendment specifies a thermal propagation test that initiates failure through cell heating. Single-cell overcharging provides an alternative where heating is technically infeasible. The acceptance criteria require no fire or explosion from the tested battery system following the initiated cell failure.
Other checks examine protections that need to act before damage escalates:
- Electrical faults: Verify protection against overcharging, excessive discharge, and short circuits
- Overheating: Assess the battery management system’s temperature protection
- Water ingress: Test the rechargeable battery system at 100% charge to the specified IPX7 requirement
A water-ingress result addresses defined laboratory conditions. Treating it as permission to drive through any flooded road would stretch the evidence beyond the test.
Performance testing asks a separate question. ISO 12405-4 sets procedures for battery-pack performance, reliability and electrical functionality. ARAI lists this standard among its traction-battery services. A safety approval alone therefore gives buyers no basis for assuming a particular driving range or battery lifespan.
Indian Approval And International Requirements Differ
For manufacturers, “battery certified” leaves an essential question unanswered: certified for what? Indian vehicle requirements, transport testing, and overseas approval serve different purposes.
| Standard | What It Addresses |
| AIS-156 | Battery safety requirements for L-category EVs, including two-wheelers |
| AIS-038, Revision 2 | Electric powertrain and battery requirements for M- and N-category vehicles, covering passenger and goods vehicles |
| UN 38.3 | Lithium-cell and battery design tests for transport |
| UN Regulation No. 100 | Electric powertrain approval requirements in markets applying the regulation |
These standards cover different approval or testing tasks; they do not represent interchangeable certificates.
US transport regulator PHMSA explains that UN 38.3 testing addresses stresses such as altitude, vibration, and external short circuits. Manufacturers and distributors make test summaries available so the supply chain can identify the tested design.
Passing transport tests does not replace the vehicle approval required by the destination market. Nor does the new laboratory announcement introduce a single certificate valid for every export destination.
For an EV purchase, ask the manufacturer which approval covers the exact model and battery configuration. For exports, confirm the destination’s requirements before commissioning EV battery safety testing.
FAQs
Does ARAI test every battery sold?
Type approval evaluates submitted designs and samples. India also requires conformity of production, which addresses continued manufacturing compliance rather than individually putting every retail battery through destructive tests.
Does IPX7 testing make an EV floodproof?
No. The specified test examines battery-system water ingress under controlled conditions. It does not establish that the entire vehicle will remain safe in every flood situation.
Is UN 38.3 enough to sell an EV abroad?
UN 38.3 concerns lithium-battery transport testing. Selling a vehicle also requires compliance with the destination’s applicable vehicle rules; transport documentation does not replace that approval process.
Can a battery pass if one cell fails?
Under AIS-156’s thermal propagation procedure, a cell entering thermal runaway does not automatically fail the tested device if no external fire or explosion occurs during testing.
Are ARAI’s additional fire safety facilities already open?
The October 31 announcement identifies additional advanced fire safety facilities as upcoming infrastructure. It does not state that those separate planned facilities have already entered operation.
