Tata Technologies' WATTSync Platform Ready for India's Battery Aadhaar System

Tata Technologies has announced that its battery intelligence platform, WATTSync, is fully equipped to support India's upcoming Battery Aadhaar digital identity and traceability requirements while maintaining compliance with EU Battery Regulation standards.

The platform is designed to generate and manage India's mandated 21-character Battery Pack Aadhaar Number (BPAN), enabling manufacturers and ecosystem partners to track batteries throughout their entire lifecycle from production through end-of-life workflows.

WATTSync features a QR-code-enabled digital identity engine that provides secure access to both static and dynamic battery data. The static data model covers manufacturer identifiers, battery descriptors, material composition, chemistry, and carbon footprint information. For dynamic data requirements such as State of Health, charge-discharge cycles, and thermal events, the platform integrates with Battery Management Systems to enable real-time analytics.

The system's microservices-driven, cloud-ready architecture allows for API-based data exchange with government-mandated central servers, ensuring traceability and auditability across the supply chain. Role-based access control provides structured data views for manufacturers, suppliers, operators, recyclers, regulators, and auditors.

Additional features include AI-driven analytics for predictive maintenance and safety intelligence, thermal anomaly detection, and remaining useful life estimation. The platform also supports circular-economy objectives through end-of-life information exchange and recovered-material documentation.

For domestic manufacturing under the ACC-PLI scheme, WATTSync provides secure provenance documentation to verify cell origin and strengthen supply chain transparency.

Tata Technologies, headquartered in Pune, is a global product engineering and digital services company. The announcement was made on February 10, 2026.
