Tata Technologies Unveils WATTSync: India’s First Digital Battery Passport Platform to Revolutionize EV Transparency

Tata Technologies has officially launched WATTSync, a digital battery passport platform that promises to transform how electric vehicle (EV) batteries are tracked, managed, and recycled. The unveiling took place on August 19, 2025, and comes at a time when global regulators are tightening requirements for battery traceability, safety, and transparency.

The platform is designed for battery manufacturers, automotive OEMs, and recycling companies, offering an end-to-end digital lifecycle record of each battery—from mining of raw materials to second-life applications and final recycling.

Why This Matters for India’s EV Industry

EU Mandate Coming in 2027: From February 2027, all EV and industrial batteries sold in the European Union must have a digital battery passport. This makes solutions like WATTSync vital for Indian OEMs looking to export EVs.

India’s Own Battery Passport Policy: The Government of India is also working on a similar framework to boost battery safety, recycling efficiency, and export readiness.

Market Advantage for OEMs: Early adopters of battery passports have already seen improved market confidence, resale value, and stronger customer trust.

Inside WATTSync: Key Features

Blockchain-enabled Data Integrity – ensures tamper-proof tracking of materials and performance metrics.
AI-Powered Battery Health Monitoring – identifies anomalies, predicts failures, and optimizes usage.
Seamless Integration – works with PLM, MES, ERP, and cloud data platforms for a unified battery digital thread.
Automated Compliance Reporting – simplifies regulatory approvals across EU, India, and other global markets.
Circular Economy Focus – provides insights for second-life applications and supports eco-friendly recycling.

Industry Impact: A Step Towards Circular Economy

By making the EV supply chain transparent, WATTSync is expected to:

• Help reduce risks linked to rare earth sourcing.

• Improve consumer confidence in EV adoption.

• Strengthen India’s position as a global EV hub.

• Open doors for higher resale value of EVs with verified battery health records.

EVINDIA Analysis: Why WATTSync Could Be a Game-Changer

The launch of WATTSync comes at a crucial inflection point. While Indian EV OEMs are struggling with raw material shortages and global supply chain disruptions, Tata Technologies is positioning itself as the tech backbone for the EV ecosystem.

With festive season sales and export ambitions rising, EV brands adopting digital battery passports early could gain a competitive advantage not just in India but globally.

EV buyers, too, stand to benefit—knowing their EV’s battery health and carbon footprint before making a purchase could soon become as common as checking a vehicle’s mileage.
