Battery Identifier Switching for Privacy-Safe Status Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery management systems face challenges in protecting privacy when managing battery information, as personal information can be traced from battery identifiers, restricting the utilization of battery information, especially after the battery is removed from a vehicle.
Innovation Solution
A battery system that includes a storage unit for storing two types of battery identifiers - one associated with personal information and another not associated with personal information - and a control unit that selectively transmits one of these identifiers along with battery information to a predetermined information processing device, ensuring appropriate privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a single battery identifier associated with personal information is used for battery management, then battery information can be traced to specific individuals, but privacy protection is compromised and utilization of battery information is restricted
Solution Approach 1:
The patent segments the battery identifier system into two distinct types: a first battery identifier associated with personal information for when the battery is mounted on a vehicle, and a second battery identifier not associated with personal information for when the battery is removed. This segmentation allows the system to protect privacy while maintaining battery information utilization by selecting the appropriate identifier type based on the battery's operational state.
2Object-affected harmful factors
If battery information is managed without associating personal information, then privacy is protected, but battery information cannot be properly traced and managed
Solution Approach 1:
The patent implements a dynamic identifier selection mechanism where the control unit switches between the first battery identifier (associated with personal information) and the second battery identifier (not associated with personal information) based on whether the battery is mounted on a vehicle or removed. This dynamic approach ensures that privacy protection and battery information management reliability are both maintained by using the appropriate identifier type for each operational context.
3Reliability
If personal information is linked to battery identifiers, then battery management can be performed accurately, but the system becomes complex and privacy-restricting
Solution Approach 1:
The patent divides the battery identifier system into two separate identifier types stored in the storage unit, each serving a specific purpose. The first identifier enables accurate battery management when mounted on a vehicle, while the second identifier provides a simplified privacy-protected identifier when removed. This segmentation reduces system complexity by creating clear, context-specific identifier usage rules rather than requiring a single complex identifier system.

AI summary
In a battery system including a battery, a storage unit, and a control unit, the storage unit stores a first battery identifier associated with personal information in another system and a second battery identifier not associated with personal information in the other system, and the control unit selectively transmits either the first battery identifier or the second battery identifier to a predetermined information processing device together with battery information related to a status of the battery.
