Battery Data Management and Analytics Platform Using Blockchain Technology

This paper proposes a blockchain-powered battery data management and analytics platform which fully utilizes blockchain technology for battery health monitoring in battery energy storage systems (e.g., electric vehicles) and accelerating battery cell development. The proposed platform consists of five distinct components: 1) blockchain clients using application SDK such as battery energy storage systems and a battery tester; 2) a multichannel blockchain network for enhanced data security, privacy, and management; 3) data preprocessing; 4) data analytics engine executing analytics tools and health monitoring algorithms; and 5) user-friendly service visualization. The proposed platform is implemented in an AWS cloud and tested using real-time battery data from a battery energy storage system (BESS) client and batch data from a battery cell tester client. The results show that each blockchain channels can independently manage and analyze data sources from two clients in a blockchain network. The proposed platform will enable a new level of data security and privacy preserved battery intelligence system used for both battery product development and lifetime battery health monitoring.
