Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery pack is mounted in the center console space, then spatial utilization is maximized and vehicle structure modification is minimized, but the cooling air flow distribution to battery modules may become uneven
Solution Approach 1:
The battery pack is divided into multiple battery modules, and the cooling air distributing means is correspondingly segmented to provide dedicated cooling channels to each module. This segmentation ensures that cooling air is distributed uniformly to all battery modules even when mounted in the constrained center console space.
Solution Approach 2:
The cooling air distributing means extends in the longitudinal direction of the vehicle to match the lengthwise mounting orientation of the battery pack in the center console. This dimensional alignment optimizes the cooling air flow path and ensures uniform cooling distribution across all modules.
2Ease of operation
If the battery pack is positioned lengthwise in the center console, then mounting workability is improved and space is optimized, but heat dissipation efficiency may be reduced
Solution Approach 1:
The cooling air distributing means acts as an intermediary component that introduces cooling air directly to each battery module. This intermediary structure enables effective heat dissipation while maintaining the space-efficient lengthwise mounting configuration in the center console.
Solution Approach 2:
The cooling air distributing means is extracted as a separate functional component from the battery pack itself, allowing independent optimization of both the battery mounting configuration and the cooling system design. This separation enables the battery pack to be mounted lengthwise for space efficiency while the distributed cooling system ensures adequate heat dissipation.
3Object-affected harmful factors
If cooling air is discharged through the battery pack to the outside, then occupant comfort is improved by preventing uncomfortable air flow, but the discharge duct complexity increases
Solution Approach 1:
The discharge duct is merged with the existing vehicle body structure, integrating the cooling air discharge function into the vehicle's overall design. This integration reduces the apparent complexity of the discharge duct system while effectively directing cooling air away from occupants.

AI summary
Disclosed is battery pack mounting structure for a high capacity battery in a vehicle. More specifically, a battery pack that includes a plurality of modules is mounted lengthwise in a center console installation space between a driver seat and a passenger seat. A cooling air providing means is configured to supply cooling air to a front protion of the battery pack, and a cooling air distributing means is configured to distribute the cooling air provided by the cooling air providing means to each of a plurality of battery modules individually. Finally, a discharge duct means is configured to receive cooling air that has already passed over each of the individual battery modules and discharge the cooling air through a rear portion of the battery pack to outside of a vehicle body.
