Risk Management Framework for EV Battery Manufacturing Facilities in India
Walk into any discussion about the future of mobility, and electric vehicles are at the centre of it. India, in particular, is moving fast. EV adoption is rising across two-wheelers, three-wheelers, and now steadily in passenger and commercial vehicles.
India recorded 28.2 million vehicle registrations in 2025, with EV sales crossing 2.3 million units — around 8% market penetration. Electric two-wheelers led adoption with a 57% share, followed by three-wheelers at 35%. National targets aim to push EV adoption to nearly 80 million vehicles by 2030 across segments.
The Government of India has set a target of 30% EV penetration by 2030, intensifying the push for domestic battery manufacturing. Gigafactories, cell manufacturing units, and battery pack assembly plants are being commissioned across the country. While this growth strengthens supply chain resilience and supports the "Make in India" vision, it also introduces a new and complex layer of industrial risk.
EV battery manufacturing facilities are fundamentally different from traditional automotive plants. They combine electrochemical processes, high-energy storage systems, precision-controlled environments, and hazardous materials within a single operational footprint. These conditions create interconnected risks that require a more structured and proactive approach to battery storage safety.
Why Risk Management Matters
EV battery plants combine flammable materials, high-voltage systems, thermal processes, robotics, solvents, and tightly controlled storage areas. That mix creates exposure to fire, explosion, chemical release, electrical shock, contamination, and production stoppages.
The Ministry of Heavy Industry has reported 26 EV fire incidents over three years in India, while the broader accident count reached 23,865 EV accidents between 2023 and 2025. While not all incidents originate in manufacturing, they underscore a critical point — failures in battery systems can have severe downstream consequences.
Battery manufacturing risk must be addressed as an enterprise-wide priority, spanning design, operations, quality, storage, and logistics — not as a siloed shop-floor issue.
Key Safety Risks in EV Battery Manufacturing
A structured risk framework begins with a clear understanding of the most critical hazards present in battery facilities:
- Thermal runaway and fire risk, triggered by internal defects, overheating, overcharging, or mechanical damage — with potential for rapid propagation across cells
- Electrical hazards, including high-voltage exposure, arc flash risks, improper grounding, and equipment overload
- Chemical exposure risks from electrolytes, solvents, and binders, which can lead to toxic exposure, spills, or environmental contamination
- Explosion risks, particularly in areas with volatile vapours, inadequate ventilation, or confined spaces
- Storage-related risks such as improper stacking, high state-of-charge storage, and lack of temperature control, increasing fire load
- Static electricity buildup, especially in dry environments, which can ignite flammable materials
- Mechanical and automation risks, including robotic movement, conveyor systems, and material handling equipment
- Supply chain-related risks, where defective or poorly handled cells enter the production process undetected
Each of these risks is interconnected. A defect introduced during cell manufacturing can evolve into a thermal event during storage or transport, making early detection and control essential.
How Is India Regulating Safety in EV Battery Manufacturing?
India's EV safety framework has evolved significantly. Standards such as AIS-156 have strengthened requirements around battery design and safety, including thermal propagation resistance, BMS functionality, insulation, and validation testing under stress conditions. These regulations are complemented by guidelines and certifications from BIS, ARAI, and MoRTH, which govern how batteries and EV systems are approved for road use.
For manufacturers, EV plant safety compliance now extends beyond factory operations. It requires alignment between product-level safety and certification requirements and facility-level controls, including fire protection, electrical safety, and hazardous material handling. A gap in either area can result in regulatory action, operational disruption, or reputational damage.
Practical Risk Management Framework for EV Battery Safety
A practical risk management framework for an EV battery manufacturing facility should be built around five layers: governance, hazard identification, controls, monitoring, emergency preparedness, and continuous improvement. Each layer should be audited at least annually and updated whenever chemistry, equipment, or capacity changes. This structure helps align EV battery safety with production efficiency instead of treating safety as a separate function.
Layer 1 Governance and Accountability
The first step is assigning clear ownership for safety across operations, engineering, maintenance, quality, EHS, procurement, and top management. A plant-level risk committee should meet regularly to review incidents, near misses, permit deviations, and audit findings. Battery manufacturing risk often spans departments, and failures usually occur at the handoff between design, production, storage, and logistics.
Layer 2 Process Hazard Identification
A detailed hazard study should map risks across the full battery lifecycle — raw material receipt, cell handling, mixing, coating, drying, assembly, formation, testing, packaging, warehouse storage, and dispatch. The assessment should evaluate chemical exposure, incompatible storage, machine guarding, runaway heat, static discharge, and human error.
Temperature, humidity, air quality, ventilation, and fire-resistant materials all shape safety outcomes. This is where battery storage safety becomes critical — even small deviations in stacking, segregation, or climate control can escalate into major loss events.
Key Risk Categories
Risk Category
Fire and Thermal Runaway
The most serious hazard in a battery plant is lithium-ion battery fire risk. Thermal runaway can start from mechanical damage, overcharging, internal defects, or BMS failure — and once initiated it can spread quickly to nearby cells or modules. EV battery safety must therefore be engineered upstream rather than relied on in firefighting alone.
Risk Category
Electrical Hazards
Battery plants work with high-voltage systems, test rigs, charging stations, conveyors, and automated equipment — creating shock, arc flash, grounding, and overload hazards. A structured electrical safety audit should cover earthing, insulation resistance, protective relays, cable routing, classification of hazardous zones, flameproof equipment, and preventive maintenance records. In Indian industrial settings, this audit is especially important for verifying statutory compliance and identifying hidden fire or shock exposure before an incident occurs.
Risk Category
Chemical and Environmental Hazards
EV battery production uses materials and processes that can generate toxic exposure, spill risk, and contamination issues. Solvents, binders, electrolytes, and cleaning agents demand ventilation, spill containment, PPE, and storage segregation. Facilities should also monitor humidity, dust, and contamination because these affect product quality and can trigger equipment malfunction. Older retrofitted facilities need additional safeguards such as clean rooms, eyewash stations, showers, and better storage separation.

Request a Hazard StudyLayer 3 Control Measures
Control measures are where risk management moves from planning to execution — ensuring that identified hazards are consistently controlled through design, processes, and human behaviour on the ground.
a) Engineering Controls
Engineering controls should be the first line of defence. These include fire detection systems, gas sensors, temperature monitoring, compartmentalised storage, blast-resistant barriers where needed, automatic shutdowns, ventilation, and safe battery segregation.
For warehouse and formation areas, battery storage safety requires strict limits on stacking height, spacing, charging state, and compatibility of stored packs. The facility design should also ensure safe coolant routing, leak detection, and emergency isolation so that a single fault does not cascade into a major event.
b) Administrative Controls
Administrative controls translate design intent into daily discipline. Standard operating procedures should cover incoming inspection, defect quarantine, hot-work permits, lockout-tagout, emergency response, and periodic housekeeping. Training is equally important because many battery incidents start with procedural drift rather than equipment failure. India's emerging safety environment — including CEA's 2026 battery storage rules and fire-safety emphasis — reinforces the need for disciplined training and audit-ready documentation.
c) PPE and Human Factors
PPE cannot eliminate hazards, but it reduces exposure during handling, maintenance, and emergency response. Facilities should provide chemical-resistant gloves, face shields, insulated tools, anti-static clothing where relevant, and respiratory protection for specific tasks. Human factors design — clear signage, colour coding, accessible exits, and simple escalation paths — reduces confusion during abnormal conditions. A mature electrical safety audit should include checking whether workers can identify isolation points, emergency stops, and hazardous zones without hesitation.
d) Storage and Logistics
Battery warehousing deserves special attention because stored inventory can become a concentrated fire load. Cells and packs should be segregated by chemistry, charge status, defect status, and packaging condition. Temperature and humidity controls need continuous monitoring, and damaged units must be isolated immediately.
Spacing, fire-resistant materials, and ventilation are all decisive in limiting propagation if a thermal event occurs. For Indian facilities operating in hot climates, this aspect of EV battery safety is especially important because ambient conditions can magnify internal heat stress.
Layer 4 Monitoring and Audits
Risk management is effective only when controls are verified in the field. Plants should use leading indicators such as near-miss reporting, sensor alarms, maintenance completion rates, and audit closure time — rather than waiting for accidents to define performance.
A recurring electrical safety audit should verify:
- Earthing systems
- Load balancing
- Panel condition
- Cable integrity
- Hazardous-area protection
A parallel process audit should review storage discipline, inspection routines, and emergency readiness. This approach supports EV plant safety compliance by demonstrating to regulators, insurers, and customers that controls are active, not paper-based.
Layer 5 Emergency Preparedness
No battery facility should assume a zero-incident environment. Emergency plans should include thermal runaway response, evacuation routes, mutual aid contacts, fire-water availability, alarm triggers, and isolation procedures for affected zones. Recent Indian policy attention around BESS and EV safety shows a stronger focus on fire systems, hazard detection, emergency stops, and competent response teams.
Because lithium-ion battery fire risk can produce intense smoke, heat, and re-ignition, drills should be scenario-based and repeated often enough to build muscle memory.

Talk to Our TeamSupply Chain and Quality Risks
A robust risk management framework for EV battery manufacturing must extend beyond the plant itself, because a significant portion of battery manufacturing risk originates upstream in the supply chain. India's growing dependence on imported cells, critical minerals, and specialised components introduces variability in quality, handling standards, and traceability.
Even minor inconsistencies — such as contamination in raw materials or micro-defects in cells — can escalate into safety incidents during formation, storage, or end use. Without strong oversight, risks such as improper packaging, transit damage, or undocumented process variations can remain undetected until they trigger failures within the facility.
Key control measures should include:
- Rigorous incoming quality checks, including batch-level inspection, random sampling, and testing for electrical, thermal, and structural integrity
- Supplier qualification and periodic audits, focusing on manufacturing processes, quality systems, and compliance with global safety standards
- End-to-end traceability systems, enabling tracking of materials and components from source to final assembly
- Standardised transport and packaging protocols, minimising exposure to shock, temperature variation, and moisture during transit
- Clear rejection, quarantine, and recall procedures for defective or non-conforming materials
As EV battery manufacturing scales, managing risk is no longer just about compliance — it is about ensuring long-term operational resilience, safety, and business continuity. From lithium-ion battery fire risk and battery storage safety to electrical safety audits and end-to-end EV plant safety compliance, every layer needs structured attention.
