Solution Overview
Problem
The existing electricity storage device design fails to separate the cooling path for batteries and the smoke discharge path, leading to inefficient cooling and potential gas mixing.
Innovation Solution
The design incorporates a T-shaped cooling path with separate intake and discharge openings, and partition plates with rib structures to isolate the cooling and smoke discharge paths, ensuring independent airflow and gas discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the cooling path and smoke discharge path are shared or overlapping, then the device structure is simpler, but the cooling efficiency decreases and gas mixing occurs
Solution Approach 1:
The patent divides the internal space into functionally separate regions: a cooling path for air circulation and a smoke discharge path for gas venting. The cooling path includes intake openings, cooling channels, and discharge openings that are spatially separated from the smoke discharge path, preventing gas mixing while maintaining structural organization.
Solution Approach 2:
Different regions of the device are assigned different functional properties: the cooling path is designed with intake openings positioned to draw cool air, cooling channels with specific cross-sectional areas optimized for heat dissipation, and discharge openings positioned away from smoke discharge paths. This local functional differentiation ensures efficient cooling without compromising safety.
2Reliability
If the cooling path and smoke discharge path are separated, then cooling efficiency and safety improve, but the device structure becomes more complex
Solution Approach 1:
The case structure serves multiple functions simultaneously: it houses the batteries, provides structural support, and incorporates both cooling channels and smoke discharge paths as integral components. The partition walls and internal structures perform both mechanical support and flow guidance functions, reducing the need for separate dedicated components.
Solution Approach 2:
The cooling path is nested within the case structure, with cooling channels formed as cavities or passages within the case walls and partitions. The smoke discharge path is similarly integrated into the case structure, with discharge openings positioned in the case body. This nesting approach allows separate functional paths without adding external complexity.
3Productivity
If the intake opening area is large, then cooling air supply is improved, but the discharge opening area must also be large, increasing device size
Solution Approach 1:
The cooling path utilizes three-dimensional space within the case structure, with cooling channels extending in multiple directions and discharge openings positioned on different faces of the case. This spatial arrangement allows efficient air circulation without requiring proportionally large opening areas, as the cooling path leverages volumetric rather than just surface area.

AI summary
An electricity storage device includes: a plurality of batteries juxtaposed in a first direction, each battery having on a first side a gas discharge valve that discharges a gas produced inside the battery; and a cooling path formed between the plurality of batteries that face each other in the first direction, constructed to convey a coolant that cools the batteries, and an intake opening for taking in the coolant on a second side that is an opposite side to the first side in a second direction orthogonal to the first direction and a discharge opening for discharging the coolant taken in on at least one of sides in a third direction orthogonal to the second direction and to the first direction.
