Pune, Mumbai, Bengaluru, Delhi, India – August 19, 2025: Tata Technologies, a global product engineering and digital services company, today announced the launch of WATTSync, a secure and scalable digital battery passport solution. Built to support sustainable engineering from raw material extraction to end-of-life recycling, WATTSync enhances transparency, regulatory compliance, and environmental accountability. It empowers OEMs (Original Equipment Manufacturers), battery manufacturers, and recyclers to operate with greater trust and innovation in a rapidly evolving global mobility landscape. “This is engineering in service of a simple promise: when you can trace it, you can trust it,” said a spokesperson from Tata Technologies.
WATTSync enables the capture and validation of comprehensive battery data across every stage—from mining and manufacturing to usage and recycling. It provides teams with a unified, real-time view of materials used, battery performance metrics, carbon footprint, and recovery status. This shared data streamlines decision-making and improves sustainability tracking throughout the battery’s lifecycle. The platform also automates compliance reporting, helping manufacturers stay ahead of constantly evolving regional and international regulations.
WATTSync’s architecture is designed for secure collaboration, offering role-based access to suppliers, auditors, and regulators—ensuring that all stakeholders work from the same trusted digital source. The system integrates seamlessly with existing PLM (Product Lifecycle Management), MES (Manufacturing Execution Systems), ERP (Enterprise Resource Planning), and cloud data lakes to create a continuous digital thread for each battery. This thread enhances operational visibility and traceability at every step.
The platform leverages AI to monitor battery health and detect anomalies early, allowing issues to be flagged before they impact customers. It simplifies the audit process with guided checks and multilingual assistance, ensuring both speed and accuracy. Blockchain technology is used to safeguard data integrity, making all information tamper-evident and trustworthy. Additionally, WATTSync is cloud-agnostic, allowing for rapid and scalable deployment across diverse geographies and infrastructure environments.
The launch comes ahead of critical regulatory shifts. From February 2027, the European Union will require a digital battery passport for all EV and industrial batteries. Forward-thinking OEMs are already adopting such systems to boost transparency and resale value. India has also declared its intention to implement a national battery passport framework to improve safety, traceability, and export potential. With other global markets preparing similar policies, WATTSync positions manufacturers to move early and adapt confidently.
Through WATTSync, Tata Technologies aims to deliver meaningful impact across the battery ecosystem. The solution enables improved circular outcomes by providing insights into second-life applications and end-of-life recycling strategies. It accelerates compliance by making audits faster and more accurate. Verified sourcing and tamper-evident data reduce operational and reputational risk. Furthermore, the AI-driven insights offer a closed-loop feedback mechanism, allowing field data to inform smarter design and engineering decisions.
