Vehicle Battery Interruption Control for Abnormal Cell Events
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems fail to balance battery protection and power supply priority when an abnormality occurs during vehicle travel, leading to potential power disruption.
Innovation Solution
An energy storage apparatus with a current interruption device and management system that adjusts control based on vehicle state, such as travel area, speed, or disaster information, to prioritize power supply or battery protection accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the current interruption device is controlled based on vehicle state, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by making the management device perform multiple functions: it monitors various vehicle conditions (travel area, speed, disaster information), processes this information, and controls the current interruption device accordingly. This multi-functional approach allows the system to adapt to different situations without requiring separate specialized systems for each function, thereby improving adaptability while managing complexity.

AI summary
An energy storage apparatus 50 for a vehicle includes a cell 60, a current interruption device 53 which interrupts current of the cell 60, and a management device 120. When an abnormality of the cell 60 is detected while a vehicle 10 is traveling, the management device 120 changes control of the current interruption device 53 in accordance with a difference in state of the traveling vehicle 10.
