Solution Overview
Problem
There is a lack of effective management systems for power supply devices, such as batteries, when they are reused, leading to potential inaccuracies in measurement and prediction of voltage and output characteristics, as well as a risk of unexpected use in secondary applications.
Innovation Solution
A power supply device management system that includes an electric moving body with a power supply device, communication unit, and control unit, along with a server device that assigns identification numbers, stores characteristic information and failure history, and compares current and registered position information to prevent unexpected use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a power supply device is used for secondary use without comprehensive management, then the device can be reused, but measurement accuracy and deterioration prediction accuracy of voltage and output characteristics deteriorate
Solution Approach 1:
The system performs preliminary actions by assigning identification numbers to power supply devices before secondary use and proactively collecting measurement history data. The server device stores characteristic information and failure history in advance, ensuring measurement accuracy is maintained from the beginning of secondary use rather than waiting for problems to occur.
Solution Approach 2:
The system implements feedback mechanisms where the communication unit periodically transmits position information and the server device compares current position information with registered position information. This feedback loop ensures continuous monitoring and maintains measurement accuracy throughout the secondary use period by detecting unauthorized movements or changes.
2Measurement precision
If a power supply device is used for secondary use without comprehensive management, then the device can be reused, but deterioration prediction accuracy of output characteristics deteriorates
Solution Approach 1:
The system performs preliminary actions by collecting and storing failure history data before secondary use begins. The server device maintains a database of characteristic information and failure history, enabling accurate deterioration predictions from the start of secondary use by analyzing patterns from previous failures and operational data.
Solution Approach 2:
The system implements continuous feedback loops where operational data and failure information are periodically transmitted to the server device. This feedback mechanism allows the system to update deterioration predictions in real-time by comparing current performance with historical failure patterns, maintaining high prediction accuracy throughout the secondary use period.
3Adaptability or versatility
If no management system is implemented for secondary use, then the power supply device can be freely used, but unexpected use occurs in the secondary use destination
Solution Approach 1:
The system implements feedback mechanisms where the communication unit periodically transmits position information to the server device, which compares current position information with registered position information. This continuous monitoring maintains reliability by detecting unauthorized movements while allowing legitimate secondary use, balancing control with adaptability.
Solution Approach 2:
The server device acts as an intermediary between the power supply device and the secondary use destination. It manages the balance between flexibility and control by processing position information, comparing it with registered locations, and enabling or disabling usage based on authorization, thus preventing unexpected use while maintaining operational versatility.
