Tata Technologies presents WATTSync platform for India’s Battery Aadhaar Framework

Tata Technologies, a product engineering and digital services company, announced that its battery intelligence platform, WATTSync, is designed to support India’s proposed Battery Aadhaar digital identity and traceability requirements. The company stated that the platform is aligned with the EU Battery Regulation (EU BR 2023/1542).

India is planning to implement a QR-code-enabled Battery Aadhaar framework to enhance traceability and compliance across the battery lifecycle. According to Tata Technologies, WATTSync supports the generation and management of the 21-character Battery Pack Aadhaar Number (BPAN) and enables integration of battery identifiers across manufacturing, operations, and end-of-life processes. The company indicated that the platform structure corresponds with global digital battery passport requirements. It also provides access to static and dynamic battery data. The platform supports prescribed Battery Aadhaar data fields, including manufacturer details, battery specifications, material composition, chemistry, and battery carbon footprint (BCF). It also manages sustainability and environmental data in line with EU regulatory requirements.

For dynamic data requirements such as State of Health (SoH), charge-discharge cycles, thermal events, and operational parameters, the platform integrates with Battery Management Systems (BMS). Tata Technologies stated that its cloud-based microservices architecture enables data ingestion and analytics to meet reporting requirements in India and the EU. To comply with requirements for storing dynamic battery data on authorized central servers, WATTSync enables API-based data exchange with government systems to support traceability and audit processes across the supply chain.

The platform’s Battery LifeCycle Manager tracks lifecycle stages from manufacturing and usage to repair, repurposing, and recycling, supporting regulatory requirements related to circularity. WATTSync includes role-based access control (RBAC) features that provide structured data access for manufacturers, suppliers, operators, recyclers, regulators, and auditors, in accordance with regulatory guidelines. The platform also incorporates analytics functions for predictive maintenance and safety monitoring, including thermal event detection, remaining useful life (RUL) estimation, and performance risk assessment.

Tata Technologies stated that WATTSync enables exchange of end-of-life data, documentation of recovered materials, and carbon footprint tracking across recycling processes. For manufacturers operating under the ACC-PLI scheme, the platform supports documentation and traceability related to cell origin. The company said the platform is intended to support compliance with digital battery identity and sustainability requirements in India and international markets.
