Solution Overview
Problem
Current battery management systems lack data transparency across all stages of the battery lifecycle, making it difficult to ensure sustainable transition to low-carbon mobility and energy storage.
Innovation Solution
A distribution module and method for managing digital battery passports, which includes a user access submodule to retrieve and transmit subset data, a collection submodule for user feedback, and a fraud detection submodule using blockchain and AI to ensure data integrity and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a centralized battery management system is implemented, then data accessibility is improved, but system complexity increases
Solution Approach 1:
The system is divided into autonomous manufacturer modules, each managing its own battery passport data independently. Each module contains creation, storage, and communication submodules that operate semi-autonomously, reducing centralized complexity while maintaining data accessibility through standardized interfaces.
Solution Approach 2:
A distribution module acts as an intermediary layer between manufacturer modules and end users. This mediator handles data retrieval requests, authenticates users, and manages communication protocols, thereby simplifying the overall system architecture by centralizing only the necessary coordination functions.
2Loss of information
If comprehensive battery data is stored centrally, then data transparency is improved, but security risks increase
Solution Approach 1:
Battery passport data is segmented and distributed across multiple manufacturer modules rather than stored centrally. Each module holds only the data relevant to its manufacturer, reducing the attack surface for fraud while maintaining transparency through decentralized access.
Solution Approach 2:
The fraud detection submodule continuously monitors data integrity and user interactions, providing real-time feedback on suspicious activities. This feedback mechanism enables proactive fraud prevention by alerting system administrators to potential security breaches before they can compromise the system.
3Reliability
If multiple access levels are implemented, then data security is improved, but ease of operation deteriorates
Solution Approach 1:
The user access submodule implements a universal authentication mechanism that handles multiple access levels through a single standardized interface. Different user roles (manufacturers, regulators, end users) are managed through role-based access control within the same authentication framework, maintaining ease of operation while ensuring data security.
