Power Storage Replacement Signaling in Mobile Body Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the management of electrified vehicles, there is a challenge in ensuring that the replacement of a power storage device is properly notified to external entities, as repair shops may inadvertently replace the device instead of repairing it, contrary to the vehicle manager's intentions.
Innovation Solution
A mobile body equipped with a control device that stores identification information of the power storage device. When the device is replaced, the control device transmits a signal to notify external entities of the replacement, ensuring that the correct actions are taken based on the vehicle manager's intentions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the control device rewrites identification information when a power storage device is replaced, then the system can track and manage replaced devices, but the original intention of the vehicle manager to repair rather than replace may be lost
Solution Approach 1:
The control device transmits a notification signal to an external device when the power storage device is replaced, providing feedback about the replacement event. This allows the vehicle manager to be informed and take appropriate actions, preventing loss of information regarding the manager's intentions while maintaining reliable tracking of replaced devices.
2Reliability
If the control device stores identification information of the power storage device, then the device can be properly identified and tracked, but the system complexity increases
Solution Approach 1:
The power storage device itself provides its identification information to the control device through self-introduction when first installed. This self-service approach eliminates the need for complex manual registration processes or additional identification equipment, achieving reliable device identification while minimizing system complexity.
3Loss of information
If the control device transmits a notification signal upon replacement, then external entities can be informed of the replacement, but communication infrastructure requirements increase
Solution Approach 1:
The notification signal transmission function is extracted from the control device and implemented as a separate, simple communication capability. This allows the replacement status information to be communicated to external entities without requiring complex communication infrastructure, as the signal transmission is handled as a basic, standalone function.

AI summary
The mobile body includes a power storage device and a control device. The control device stores identification information of a first power storage device when the first power storage device is installed in the mobile body as the power storage device. When the first power storage device is replaced with the second power storage device and the identification information of the first power storage device stored in the control device is rewritten to the identification information of the second power storage device, the control device transmits a first signal indicating that the power storage device is replaced to the outside of the mobile body.
