Authorized Battery Pack Switching for Secure Energy Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rechargeable batteries and accumulators are misused for unauthorized devices and temporary use, lacking effective prevention and billing mechanisms for rental systems.
Innovation Solution
Integration of an authorization unit and switching means in the battery or accumulator to ensure only authorized users can access energy supply, with temporary or permanent authorization management, and asymmetric cryptographic security for wireless authorization transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authorization unit and switching means are integrated into the battery, then misuse prevention and temporary use verification are improved, but device complexity increases
Solution Approach 1:
The authorization unit and switching means are integrated into the battery pack, combining authorization management and power control functions into a single device. This merging approach enables misuse prevention and temporary use verification while avoiding the need for separate external authorization systems, thus addressing the contradiction between improved reliability and reduced device complexity.
2Reliability
If switching means is integrated into the supply line, then energy supply control is improved, but device complexity increases
Solution Approach 1:
The switching means is integrated directly into the supply line within the battery pack, merging the power control function with the existing energy transmission path. This integration enables precise control of energy supply to authorized devices while minimizing additional structural complexity, as the switching component becomes part of the existing supply infrastructure rather than an separate add-on.
3Reliability
If wireless interface with cryptographic security is added, then authorization security is improved, but device complexity increases
Solution Approach 1:
A wireless interface with cryptographic security protocols is introduced as an intermediary between the authorization unit and external devices. This intermediary layer enables secure key exchange and authorization verification without requiring physical contact or manual configuration, thus improving authorization security while the modular design keeps the added complexity manageable.
