Que: Can you tell us about Tata Technologies’ WATTSync solution and the core challenges it addresses in the battery passport landscape?

Ans: WATTSync is our cloud-based, API-driven digital battery passport platform. It addresses three industry-level pain points: fragmented lifecycle data across suppliers, evolving regulatory requirements, and limited end-to-end visibility from raw material mining through repurposing and recycling. Leveraging our turnkey engineering expertise, the platform supports adherence to global mandates like the EU Battery Regulation 2023/1542, while also guaranteeing smooth integration with systems, geographies, and supply chain partners. It enables end-to-end traceability from raw material sourcing to end-of-life recycling, ensuring transparency, compliance, and efficiency. Built by a global team drawing on powertrain, connected vehicle, AI/ML, and cybersecurity expertise, it goes beyond basic compliance by adding AI-powered prognostics and insight services. The solution tackles issues like disjointed supplier records, manual compliance reporting, and the need for carbon footprint and due diligence disclosures by offering a unified digital backbone that integrates seamlessly across the supply chain.

Que: How does WATTSync help OEMs and battery manufacturers meet complex compliance requirements?

Ans: WATTSync simplifies compliance by centralising lifecycle data and automating audit-ready documentation. It aligns with evolving frameworks such as the EU Battery Regulation, India’s EPR requirements, and Global Battery Alliance standards.

Through features like blockchain-secured records, role-based access, and integration with PLM, MES, and ERP systems, WATTSync reduces manual overhead, eliminates duplication and ensures regulatory reporting is both accurate and efficient. This allows OEMs and battery manufacturers to focus on innovation while maintaining full compliance across geographies.

Que: Tata Technologies has piloted WATTSync in regions like the UK, South Asia, and Vietnam. Can you share key learnings and outcomes from these deployments?

Ans: We have run two types of engagements: battery passport pilots and AI/ML prognostics pilots. For battery passport, we connected WATTSync to an India-based pack engineering company’s back end to demonstrate as-built traceability and are progressing to a second phase. For prognostics, pilots with a UK OEM and a Vietnamese OEM focused on predicting battery and e-powertrain issues that drive warranty cost and customer downtime; early results validated the value of anomaly detection and proactive notifications. The common learning across regions: interoperability, ease of integration, and stakeholder onboarding are as critical as the data model itself.

Que: How can digital platforms like WATTSync serve as a bridge between compliance and operational efficiency?

Ans: WATTSync turns compliance into a value driver by linking regulatory requirements with operational insights. By automating compliance checks and generating reports in real time, the platform eliminates the burden of manual processes. At the same time, its AI-powered analytics provide predictive insights that improve battery design, performance monitoring, and lifecycle management. This dual capability ensures that compliance is not just a box to tick, but a lever for efficiency, innovation, and cost optimisation.

Que: With upcoming battery regulations, how are OEMs, battery manufacturers, and Tier 1 suppliers rethinking their product and data strategies?

Ans: We’re seeing a shift toward cross-functional ownership and an API-first digital backbone. Teams are aligning on a single traceability framework that touches on-car software, core enterprise systems, and supplier processes, as meeting passport requirements cuts across engineering, manufacturing, aftersales and IT. There is also a stronger focus on embedding sustainability metrics, such as carbon footprint and recycled content, into product reporting. This is accelerating the adoption of digital tools like WATTSync, which bridge compliance, transparency and performance in one ecosystem.

Organisations are prioritising data quality, integration readiness and governance so they can be compliant on time and still unlock insights for reliability, warranty, and customer experience.

Que: What role do technologies like AI, blockchain, and IoT play in the secure and intelligent management of product data and how is Tata Technologies preparing for the convergence of these technologies?

Ans: AI, blockchain and IoT form the technological foundation of WATTSync. Blockchain ensures tamper-proof traceability, AI provides predictive insights on performance and compliance, and IoT enables real-time monitoring and data collection across the battery lifecycle. We are preparing for this convergence through our cloud-agnostic, API-first architecture, which integrates with enterprise systems and allows secure collaboration across stakeholders. By embedding intelligence and security into every stage of the battery lifecycle, WATTSync positions OEMs and suppliers to unlock business value while staying compliant with global regulations.
