Battery Authentication for Vehicle Swap Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems require users to carry user cards or terminals for authentication during battery replacement, increasing labor and complexity, and lack efficient methods to prevent unauthorized use of batteries across different vehicles.
Innovation Solution
A management device that obtains and authenticates user information from batteries, allowing for seamless battery replacement without additional user cards or terminals, and uses identification information stored in batteries to manage and track usage, reducing unauthorized use by associating user and vehicle information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user cards or terminals are used for authentication during battery replacement, then authentication reliability is improved, but device complexity and labor requirements increase
Solution Approach 1:
The battery unit itself stores and provides authentication information (user ID, vehicle ID) directly to the management device, eliminating the need for separate user cards or terminals. The battery performs the authentication function autonomously through its built-in communication interface, reducing system complexity while maintaining security.
Solution Approach 2:
The battery unit serves multiple functions: energy storage, authentication information storage, and direct communication with the management device. By integrating these functions into the battery itself, the system eliminates separate authentication devices and reduces overall system complexity.
2Reliability
If user cards or terminals are required for battery replacement, then authentication control is improved, but ease of operation deteriorates
Solution Approach 1:
The battery autonomously provides its own authentication information to the management device without requiring user intervention with separate cards or terminals. The user simply presents the battery, and the management device automatically verifies authentication credentials stored within the battery itself, making the process as convenient as the existing swap operation.
3Adaptability or versatility
If batteries are not associated with specific users and vehicles, then battery availability is improved, but loss prevention deteriorates
Solution Approach 1:
The management device receives authentication information from the battery, verifies it against stored records, and provides feedback by either permitting or denying the swap operation. This automated verification process ensures that only authorized user-vehicle-battery combinations can proceed, preventing theft while maintaining efficient battery availability for legitimate users.
Solution Approach 2:
The management device acts as an intermediary between the battery and the swap infrastructure, mediating the authentication process by verifying the battery's credentials and controlling access. This intermediary layer ensures secure association between batteries, users, and vehicles without impeding legitimate battery availability.

AI summary
A management device manages batteries. The management device includes an obtaining portion that obtains, from batteries, specific information that specifies identification information of a vehicle that has used the batteries. The management device includes an authenticating portion that authenticates a user by using the specific information obtained from the batteries. The management device includes a replacement receiving portion that receives replacement of the batteries if the authenticating portion authenticates the user.
