Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage battery control devices, such as those described in WO2017/029715, fail to provide external notification of water immersion information, which is crucial for preventing secondary disasters.
Innovation Solution
An electric storage device comprising a plurality of battery packs, a control device, submersion sensors, and a notification unit that communicates immersion information to the outside, allowing for the determination and external notification of immersion levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a submersion sensor is provided inside the battery pack to detect water immersion, then the ability to detect immersion anomaly is improved, but the ability to notify external systems of the immersion status deteriorates
Solution Approach 1:
The control device serves as an intermediary between the submersion sensor inside the battery pack and external systems. The sensor detects immersion status and transmits this information to the control device, which then notifies external systems of the immersion condition. This mediator approach allows internal detection to be communicated externally without requiring direct external sensor placement.
2Quantity of substance
If multiple battery packs are combined to increase capacity, then the battery capacity is improved, but the complexity of monitoring and controlling immersion status across all packs deteriorates
Solution Approach 1:
The control device performs multiple functions: it manages the battery packs for capacity optimization and simultaneously monitors immersion status across all packs through their respective submersion sensors. This multi-functional approach consolidates monitoring responsibilities into a single control device, managing complexity while supporting increased battery capacity through multiple packs.
