Battery Pack Wireless Data Access With Privilege Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for obtaining battery pack data, such as using OBD2 ports or QR codes, are cumbersome, time-consuming, and inefficient, requiring physical connections and manual scanning, which disrupt workflows and limit access to battery information.
Innovation Solution
A computer system that authenticates portable client devices within a specific distance of a battery pack, determines their privilege level, and enables wireless transmission of battery data based on that level, allowing secure and tiered access to battery pack information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional OBD2 port method is used to obtain battery pack data, then physical connection is established for data access, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical OBD2 physical connection system with a wireless communication system. The battery management system transmits data wirelessly to portable computing devices, eliminating the need for physical plugging and unplugging of connectors, thereby reducing time loss while maintaining data access reliability through authenticated wireless channels.
Solution Approach 2:
The patent introduces a wireless communication intermediary (wireless transceiver system) between the battery management system and portable devices. This intermediary enables data transmission without direct physical contact, resolving the contradiction by providing both reliability through structured communication protocols and speed through wireless transmission capabilities.
2Ease of operation
If QR code scanning is used to access battery information, then manual scanning is required, but the process remains inefficient and labor-intensive
Solution Approach 1:
The patent implements a self-service system where the battery management system automatically initiates and manages wireless data transmission. Portable computing devices can access battery information by simply being in proximity to the battery pack, eliminating the need for manual QR code scanning or active user initiation, thereby improving both ease of operation and workflow efficiency.
Solution Approach 2:
The battery management system performs preliminary actions by pre-establishing wireless communication readiness and maintaining data in transmit-ready state. This eliminates the need for manual scanning actions at the moment of data access, allowing instant retrieval and improving workflow efficiency while maintaining ease of operation.
3Reliability
If battery packs are brought to designated workstations for data transfer, then data access is possible, but workflows are disrupted due to movement requirements
Solution Approach 1:
The patent replaces the mechanical movement-based data transfer system (physically moving battery packs to workstations) with a wireless communication system. Data transmission occurs in place through wireless signals, eliminating the need to move battery packs and maintaining workflow continuity while ensuring reliable data transfer through authenticated wireless channels.
4Adaptability or versatility
If unrestricted access to battery pack data is allowed, then all users can view information, but security is compromised for sensitive data
Solution Approach 1:
The patent applies local quality by assigning different access permissions to different users or devices based on their authorization levels. The battery management system evaluates credentials of portable computing devices and transmits only appropriate portions of data, allowing flexible access for different user roles while maintaining security for sensitive information through differentiated permission levels.
