Smart Battery Authorization via Cryptographic Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The use of unauthorized or counterfeit battery packs in mobile devices can lead to damage, safety risks such as overheating, liquid leaks, or explosions, as they may have similar external characteristics to authorized packs, causing confusion for consumers and posing injuries.
Innovation Solution
Implementing a system where mobile communication devices undergo an initial and subsequent authorization process with a smart battery, utilizing a battery authorization server to verify the battery's identity and authorization status through cryptographic methods and digital signatures, preventing unauthorized batteries from charging or being used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery packs have similar external physical characteristics, then consumer confusion increases and unauthorized batteries can be used, but manufacturing cost and complexity increase due to authorization verification systems
Solution Approach 1:
The patent introduces a battery authorization server as an intermediary between the mobile device and the battery pack. The server stores authorization information and verifies battery identities through cryptographic challenge-response protocols, eliminating the need for complex verification logic in the mobile device while ensuring reliable authorization.
Solution Approach 2:
The authorization verification functionality is extracted from the mobile device and relocated to a dedicated battery authorization server. This separates the verification logic from the end-user device, reducing device complexity while maintaining security through centralized authorization management.
2Reliability
If cryptographic verification methods are implemented, then unauthorized batteries are prevented from charging, but processing time and energy consumption increase
Solution Approach 1:
Battery authorization information is pre-configured in the battery pack during manufacturing. The battery contains pre-stored cryptographic credentials and authorization data, allowing for rapid verification without requiring time-consuming setup or registration processes at the point of use.
Solution Approach 2:
The patent replaces physical security mechanisms with cryptographic verification methods. Instead of relying on physical security features that require manual inspection, the system uses automated cryptographic challenge-response protocols that can be verified rapidly through digital communication between the battery, mobile device, and authorization server.

AI summary
A mobile communication device is capable of communicating with a battery authorization server. Determining an authorization status of a smart battery currently powering the mobile communication device involves an initial authorization process and a subsequent authorization process. The initial authorization process is conducted between the mobile communication device and the smart battery. If the initial authorization process is successful, it is followed by a subsequent authorization process between the mobile communication device and the battery authorization server.
