Geely and CATL back China’s new battery ID platform to standardise data for global EV markets
China’s automotive and battery sectors are advancing digital data standards as electric vehicles and energy storage products expand internationally. At the 2025 Automotive Intelligent Data Ecosystem Conference in Tianjin, Geely, Great Wall Motor, Chery and Nio, alongside battery suppliers including CATL, FinDreams Battery and CALB, presented progress on the Battery ID digital ecosystem initiative, which establishes a unified framework for reliable battery data. The conference also highlighted broader developments in the automotive industry’s trusted data space, covering batteries, insurance, communications and charging infrastructure, as reported by CCTV.
The initiative is led by China Automotive Data Company, which developed the Battery ID program following earlier work on power battery lifecycle tracking. The program focuses on how manufacturers and suppliers can manage secure, consistent battery information while meeting regulatory requirements across different markets. As exports rise, companies increasingly need data systems that support verification of production details, compliance information and technical specifications.
According to Wang Pan, director of the company’s power battery division, the core of the solution is the China Battery ID platform, which integrates a complete indicator system and includes the Battery ID management system, the Data Interaction Connector and the Battery ID service platform. These components support standardised data collection, system integration and the generation of unique battery identifiers. In 2024, the platform integrated data acquisition, integration, and ID generation into a complete workflow, enabling the first participating companies to enter the Battery ID trusted data space.
For 2025, the program’s scope has expanded to energy storage batteries. China Automotive Data Company has collaborated with TUV South to introduce the first Battery ID certification rules, covering data accuracy, integration processes and transmission security. Thirteen companies formed seven joint working teams to test connectivity and authentication in operational scenarios. During the conference, four automakers and three battery manufacturers issued eleven Battery IDs for power batteries and two for energy storage batteries. The IDs were produced after deploying the Data Interaction Connector and completing certification, indicating that cross-company data exchange requirements were met.
In addition to Battery ID developments, the conference officially launched the “Automotive Industry Trusted Data Space Platform” to explore national automotive data infrastructure and public service capabilities. China Automotive Technology & Research Centre vice general manager Gong Jinfeng explained that the centre is undertaking national-level infrastructure and data space construction tasks, aiming to promote secure, interoperable data flows across multiple industry sectors. A technical committee was also established to guide the platform’s standards, including alignment with national data infrastructure requirements, interoperability, and security management.
China Automotive Data Company also initiated a cross-border data circulation pilot with the Tianjin Dongjiang Free Trade Zone, Geely Auto and CATL. The pilot will implement classification standards, build a data circulation service centre, and simulate end-to-end cross-border data flows to support the compliant transmission of verified battery information to international markets.
