Tata Technologies launches digital battery passport solution

Tata Technologies has launched a digital battery passport solution called WATTSync. A digital battery passport contains the information of an individual battery, documenting its entire lifecycle, from the initial sourcing of raw materials throughout refurbishment and recycling.

According to the Pune-headquartered digital services company, WATTSync will improve transparency and efficiency, and help OEMs, battery makers, and recyclers to operate in the evolving global mobility landscape.

WATTSync will capture and validate battery data through the mine to mobility to recycling stage. It will offer secure and role-based access to suppliers, auditors, and regulators, while also providing teams with a live, shared view of materials, performance, carbon footprint, and recovery status.

WATTSync connects product lifecycle management (PLM), manufacturing execution system (MES), enterprise resource planning (ERP), and cloud data lakes to build a digital thread for each battery. AI monitors health and anomalies, flags issues before they impact customers, and simplifies audits with guided checks and multilingual assistance. Blockchain safeguards data integrity. Deployment is cloud-agnostic for speed and scale across regions.

This solution aims at circular outcomes that can be achieved with second-life and recycling insights, while faster, audit-ready compliance ensures efficiency and transparency. Verified sourcing and tamper-evident data help lower risks, and AI-led insights with closed-loop feedback from field to engineering enable smarter design decisions.

Tata Technologies announced this solution, as by February 2027, EV and industrial batteries sold into the EU will require a digital battery passport. Further, India has announced its intent to roll out a battery passport regime, while many other countries are in the process of announcing their regulatory scope and timelines.
