Tata Technologies has entered the fast-growing digital battery passport (DBP) space with the launch of its new platform, WATTSync. Introduced last month, the cloud-based system combines artificial intelligence for monitoring battery health and blockchain technology to ensure data integrity, offering scalability across global markets.
The initiative reflects a broader movement toward adopting DBPs as a standard requirement for electric vehicles and industrial batteries. The European Union has already established regulations mandating DBPs from February 2027. Under these rules, every battery sold in the EU must carry a digital record accessible through a QR code, containing detailed information on the origin of materials, carbon emissions, compliance status, and recycling efficiency.
Expanding Global Standards
Beyond Europe, several major economies are advancing their own DBP frameworks. China has introduced its own program and is reportedly considering extending it beyond batteries to sectors such as textiles and steel, which are also resource intensive. Countries including the United States, the United Kingdom, Japan, Canada, and India are likewise working toward building national DBP standards.
Meanwhile, a number of multinational corporations have already rolled out battery passport solutions. Companies such as Bosch SDS, AVL, DENSO, Umicore, Open Battery Passport, Siemens, and BloqSens AG are among those leading early adoption efforts. This signals strong industry momentum toward universal implementation.
How DBPs Work
A digital battery passport is designed to provide a comprehensive record of a battery’s journey, spanning extraction of raw materials to end-of-life recycling. In the case of EU compliance, DBPs ensure adherence not only to the Battery Regulation but also to broader supply chain accountability standards.

Each DBP is structured into three layers. The first is a public layer, containing information that can be accessed by scanning a QR code. The second is a restricted layer, holding more sensitive data such as sourcing information and technical specifications, which is available only to authorized stakeholders. The third is a dynamic layer, which continually updates battery performance metrics throughout its operational lifespan.

At the core of the system, every battery is assigned a unique digital identity. This identity logs crucial details such as raw material origin, chemical composition, durability, carbon footprint, and manufacturing processes. By tracking these elements, DBPs promote transparency across the battery supply chain and create the foundation for a circular economy.
Supporting Circular Economy and EV Growth
The introduction of DBPs is intended to reduce hazardous waste and encourage sustainable reuse. Batteries that have reached the end of their automotive life cycle may be repurposed for stationary energy storage, while recyclable components can be recovered more effectively.
For electric vehicle manufacturers and consumers alike, DBPs offer an added advantage of enhancing trust and market value. Clear documentation of compliance and environmental responsibility may contribute to stronger consumer confidence and potentially higher resale prices for EVs.
Global Battery Alliance’s Role
The Global Battery Alliance (GBA), which brings together governments, businesses, and industry associations, first introduced the DBP concept in January 2023. Since then, it has been widely recognized as the international benchmark for transparency in the battery sector. The GBA’s framework has become a guiding force for initiatives like WATTSync and others, as countries and corporations align with global standards for cleaner, more accountable energy technologies.
Tata Technologies’ launch of WATTSync positions India within this expanding movement, signaling the country’s commitment to advancing EV adoption and sustainability. With international regulations tightening and industry adoption accelerating, DBPs are set to become a cornerstone of the global transition toward greener mobility and resource-efficient energy systems.
