As India accelerates toward a future shaped by digitalization and large-scale electrification, the importance of robust and transparent energy storage systems has become undeniable. Lithium-ion batteries are the foundation of this transition. Their efficiency, light weight, and reliability make them essential for powering electric vehicles (EVs), household energy systems, industrial operations, and grid-scale storage.
India’s fast growing EV market supported by strong policy frameworks and manufacturing incentives is powering a nationwide clean mobility revolution. However, this rapid expansion also exposes critical challenges like end-of-life management, recycling inefficiencies, raw material scarcity, electrochemical complexities, manufacturing intensity, module durability issues, and overall resource depletion. These issues underline the necessity for structured battery details, standardized battery numbers, and traceable identifiers that remain consistent across manufacturing, service, and recycling.
To address these growing concerns, the Guidelines for Implementation of Battery Pack Aadhaar System, introduced under MoRTH’s draft framework and closely aligned with India’s e Mobility R&D Roadmap for Battery Pack, represent a transformative step.
The centerpiece of this initiative is the Battery Pack Aadhaar Number (BPAN), an indigenous digital identity designed to deliver complete lifecycle traceability for every battery pack, including its unique battery barcode number, associated battery part number, and relevant classifications like battery pack HSN code and battery pack HS code.
BPAN is not just a tracking mechanism, it is a structural framework that strengthens India’s sustainability, accountability, and regulatory governance across the battery value chain.
In this article, we’ll look at the Battery Pack Aadhaar number’s structure, implementation, benefits, and real-world implications.
What Is the Battery Pack Aadhaar Number?
The Battery Pack Aadhaar Number (BPAN) is a 21-character alphanumeric unique identification number assigned to each battery pack entering the Indian market. While it primarily targets EV batteries, the framework also applies to industrial batteries above 2 kWh capacity.
Functioning as a digital passport, BPAN enables lifetime traceability: from raw material sourcing and cell manufacturing to usage, second life deployment, recycling, and final disposal. Drafted by the Ministry of Road Transport & Highways (MoRTH) in early 2026, the system embeds critical data directly into the code, enabling offline decoding, and links to a centralized digital portal for real time updates throughout the battery’s operational life. Such structured identity becomes an essential part of modern battery pack instructions, ensuring compatibility with downstream processes such as recycling, reuse, or component replacement.
By integrating identification and lifecycle data into a unified architecture, BPAN directly addresses long-standing sustainability, safety, and transparency challenges in India’s battery sector.
Why India Needs Battery Traceability
India’s EV market is projected to reach millions of units annually by 2030, making lithium-ion batteries as the primary power source. However, this growth presents urgent challenges: toxic leakage from poorly managed disposal, shortages of critical minerals such as lithium and cobalt, and a recycling rate that currently remains below 5%.
Without unique identification, battery packs become increasingly opaque in which manufacturing defects are difficult to trace, operational data becomes scattered across disconnected systems, and end-of-life procedures lack clarity around materials and safety profiles. As urbanization intensifies and grid storage applications expand, these risks multiply across sectors.
BPAN directly tackles these issues by enabling standardized traceability across the entire battery lifecycle. It also aligns with broader national initiatives—India’s e Mobility R&D Roadmap, Production Linked Incentive (PLI) schemes, FAME subsidies, and ISO 26262 safety standards, ensuring that lifecycle data supports compliance as well as product innovation.
Ultimately, comprehensive tracking not only reduces waste but also strengthens India’s ambitions to reach 80% domestic recycling capacity by the end of the decade.
Multi Layered Identification in Battery Pack Aadhaar System:
The Battery Pack Aadhaar system uses a variety of digital identifying mechanisms, including a unique 21-character alphanumeric code, QR code, and server-linked data storage, to capture and retrieve battery-specific information throughout its lifecycle, as shown. Beyond the core 21-digit Battery Pack Aadhaar Number (BPAN), scannable QR codes provide access to essential static data such as battery material, descriptor, and carbon footprint parameters, as well as server-based data, which includes critical parameters and operates as an internet-based method with data stored on a centralised server.
1. The 21 Character Alphanumeric BPAN Code
Each battery is physically identified by a unique 21-character alphanumeric code physically embedded onto each battery. This code is intended to be self-descriptive, allowing crucial battery information to be extracted even when no internet connection is available. Every character in the code corresponds to a predetermined data element, allowing the battery’s key attributes to be systematically decoded in total compliance with BPAN standards.
2. QR Code–Based Identification
To complement the alphanumeric code, the system incorporates a QR based method that stores key static information. This QR code provides offline access to critical static information such as battery composition, identifying details, and carbon footprint indicators. This information is readily available to recyclers, allowing for optimal material recovery, increased recycling efficiency, and a reduction in battery waste across the value chain. The QR code contains important battery-related information designed to help recyclers during the recycling process. Each parameter is encoded using specific alphanumeric characters, allowing for easy identification and methodical interpretation of the battery’s key characteristics, as seen in the image below.
3. Server-Based Battery Dynamic Data (BDD)
The Battery Pack Aadhaar framework also includes a server-based data layer for managing Battery Dynamic Data (BDD), which is constantly updated and maintained via a centralised digital infrastructure. This internet-connected solution securely records critical operational, performance, and lifecycle parameters, providing consistent access to current battery statistics.
This centralized data availability is particularly valuable for second-life applications, where stakeholders need accurate insights into a battery’s condition before redeployment or resale. The server architecture is deliberately scalable, built for future enhancements, and organized using standardized digit allocations for consistency and long-term data management. It also improves compatibility checks for components such as battery pack connectors during maintenance or reuse cycles.
Implementation Through MoRTH and AIS Standards
Ministry of Road and Transport & Highways (MORTH) is awaiting a committee report on the detailed implementation of the Battery Pack Aadhar Number. The ministry has also recommended rolling out the framework through the Automotive Industry Standard (AIS) process, ensuring stakeholder consultation, technical validation, and alignment with existing automotive regulations.
This approach ensures that the BPAN framework is both technically sound and operationally feasible across India’s manufacturing ecosystem.
The Strategic Value of BPAN Across the Ecosystem
The Battery Pack Aadhaar Number is not an isolated identifier—it is an ecosystem wide enabler. The framework delivers structured benefits to every participant in the battery lifecycle.
For OEMs: Lifecycle Accountability and Quality Assurance
BPAN enables OEMs to track every battery pack from cell sourcing and manufacturing to integration and end of life. This improves visibility into supplier quality, strengthens batch level consistency checks, and supports rapid root cause analysis for incidents such as thermal events or performance degradation. It mitigates warranty risk exposure, and improves lifecycle accountability in EV initiatives.
For Tier 1 Suppliers: Enhanced Validation and Compliance Rigor
Tier 1 suppliers working on battery systems, BMS units, or powertrain subsystems gain high fidelity traceability linked to testing datasets, calibration data, and validation records. This improves accountability during system integration, streamlines cross-functional verification operations, and facilitates compliance audits. It also ensures that battery packs integrated into cars fulfill uniform performance, safety, and reliability standards.
For Regulators: Data Driven Governance
BPAN provides regulators with structured, datadriven visibility into battery deployment across the ecosystem. It speeds up safety investigations by linking issues to specific manufacturing batches, design variants, or operating conditions. Over time, the aggregated data supports policy refinement, improved safety standards, recycling obligations, and broader standardization efforts, helping regulators move from reactive enforcement to proactive, ecosystemwide governance.
