Portable Charger Authentication for Fast Wireless Charging Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charging systems for portable chargers require time-consuming authentication processes, delaying the start of charging and inconveniencing users in urgent need of power.
Innovation Solution
A charging service system that includes a wireless power transfer device, a portable charger with a pre-assigned battery ID, and a mobile communication terminal with application software, enabling rapid authentication and charging initiation through a service server that associates battery IDs with user IDs, allowing instant validation of charging rights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication processes are used in charging systems, then security and user verification are ensured, but charging start time is delayed
Solution Approach 1:
The system performs authentication in advance by storing battery ID and user ID associations in the service server before charging is needed. When a portable charger is placed on the charging apparatus, the pre-stored authentication data enables immediate charging start without real-time authentication delays
Solution Approach 2:
The system creates a digital copy of authentication credentials (battery ID and user ID association) stored in the service server, allowing the charging apparatus to verify user rights without contacting the user or performing time-consuming authentication procedures at the charging location
2Ease of operation
If rapid charging service is implemented, then user convenience is improved, but system complexity increases
Solution Approach 1:
The service server acts as an intermediary that manages the complexity of authentication and user management. The charging apparatus only needs to communicate with the service server to verify battery ID and user ID associations, simplifying the charging apparatus design while enabling rapid charging service
Solution Approach 2:
The service server provides multiple functions including authentication, user management, and charging coordination through a single centralized system, reducing overall system complexity by consolidating these functions rather than distributing them across multiple components

AI summary
A portable charger has a pre-assigned battery ID. The portable charger includes a wireless power receiving device corresponding to a wireless power transfer device, and a communication device being communicable with a mobile communication terminal. The mobile communication terminal stores the battery ID and a user ID in association with each other. The service server stores the battery ID, the user ID, and a validity of a service user's right to receive a chatting service, in association with each other. The service server is configured to acquire the battery ID and the user ID from the mobile communication terminal and execute an authentication process of determining the validity of the service user's right to receive the charging service for the portable charger that is, identified by the acquired battery ID based on the acquired user ID.
