Battery Pack Data Buffering for Secure Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data transmission methods between electrical machines and central control units are limited in efficiency and security, particularly in scenarios where battery packs are alternately used between machines and chargers, lacking a reliable and secure data bridge.
Innovation Solution
A battery pack with an electrical energy store, data memory, and interface that buffers and transmits data between electrical machines and central control units, incorporating protected memory for authentication and additional information collection, enabling secure and efficient data exchange without direct network connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission is performed directly between electrical machine and central control unit, then data transmission speed is improved, but system complexity and security requirements increase
Solution Approach 1:
The battery pack serves as an intermediary data transmission medium between the electrical machine and central control unit. It buffers data locally in its data memory and transmits data during charging operations, eliminating the need for direct communication infrastructure while maintaining secure data exchange.
2Reliability
If battery pack stores data locally, then data transmission security is improved, but data access efficiency deteriorates
Solution Approach 1:
The battery pack performs preliminary data buffering during charging operations, storing data in its data memory in advance. This allows data to be readily available for subsequent retrieval without requiring real-time access to the electrical machine or central control unit, reducing data access delays while maintaining security.
3Reliability
If protected memory is implemented for authentication, then data security is improved, but device complexity increases
Solution Approach 1:
The battery pack's data memory serves multiple functions: it acts as both a secure protected memory for authentication and identification information, and as a general data buffer for transmitting operational data. This multi-functionality implements security features without requiring separate dedicated security hardware, thereby limiting complexity increase.
Data Source
AI summary
A battery pack includes an electrical energy store, a data memory and an interface for the alternative connection of the battery pack to a data source or a data sink. The data memory is designed to receive data from the data source while the interface is connected to the data source, and to supply the data in the data memory to the data sink while the interface is connected to the data sink.
