Battery Management Device Authentication via Identification Transfer
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 risk of unauthorized battery usage, especially in scenarios like electric motorcycles that use multiple batteries.
Innovation Solution
A management device that obtains and writes identification information from used batteries to new ones, allowing authentication without user cards or terminals, and uses a management server to validate user identity and prevent unauthorized usage by dispersing identification information across multiple batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users carry user cards or terminals for authentication during battery replacement, then authentication can be performed, but user labor increases and the risk of unauthorized battery usage increases
Solution Approach 1:
The battery itself performs authentication by transmitting its unique identification information to the management device. The battery acts as its own authentication credential, eliminating the need for separate user cards or terminals. This self-service approach reduces user labor while maintaining security through the battery's inherent identification capability
Solution Approach 2:
The battery serves multiple functions: it provides power storage and simultaneously acts as an authentication credential. By integrating identification information directly into the battery, the system combines the functions of power delivery and user verification into a single component, reducing the need for separate authentication tools
2Ease of operation
If identification information is stored in a single location, then authentication is simple, but the risk of battery theft and unauthorized usage increases
Solution Approach 1:
The system segments identification information across multiple batteries used by a single user. Instead of storing all identification data in one location, the management device distributes and stores portions of identification information across different batteries in the user's set. This segmentation makes theft more difficult while maintaining authentication simplicity through the collective verification of multiple batteries
3Use of energy by moving object
If multiple batteries are used in electric motorcycles, then energy capacity increases, but the risk of unauthorized usage and theft increases
Solution Approach 1:
The system merges the authentication functions of multiple batteries into a unified verification process. The management device collects identification information from all batteries in the set and verifies them collectively against stored authentication data. This merging approach maintains the energy capacity benefits of multiple batteries while enhancing security through combined verification, preventing unauthorized usage of individual batteries

AI summary
A management device is a management device that: manages batteries; receives a first battery; and supplies a second battery. The management device includes an obtaining portion that obtains, from the first battery, first identification information stored in the first battery. The management device includes an authenticating portion that authenticates a user of the first battery by using the first identification information the obtaining portion has obtained. The management device includes a writing portion that, if the authenticating portion authenticates the user, writes the first identification information to the second battery that is to be supplied to the user.
