Battery Pack Reinforcement Layout for Cable Routing Strength
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery pack configurations in electric vehicles face challenges in maintaining the strength of the reinforcement member while accommodating the low-voltage connection assembly, leading to potential degradation and reduced safety during impacts.
Innovation Solution
A battery pack design featuring an arch-shaped reinforcement member that allows the low-voltage connection assembly to pass through its inner side, enhancing the compactness and dispersing force effectively, while maintaining the strength of the reinforcement member, and incorporating a high-voltage connection assembly within a receiving section to prevent cable bundle deformation during collisions.

If the cable bundle is placed in the gap between multiple battery modules to reduce space occupation, then the space utilization is improved, but the reinforcement member must be provided with a breach or disconnected which degrades its strength
Solution Approach 1:
The low-voltage connection assembly is nested within the arch-shaped part of the reinforcement member, passing through its inner side. This allows the cable bundle to be accommodated within the structural form of the reinforcement member itself, eliminating the need for breaches while maintaining both space efficiency and structural integrity.
Solution Approach 2:
The reinforcement member is designed with an arch-shaped part that curves upward, creating a natural passage for the low-voltage connection assembly. This curved geometry allows the cable bundle to pass through the inner side of the arch without requiring any breaches in the reinforcement member, thereby maintaining its strength while accommodating the electrical connections.
2Ease of operation
If the reinforcement member is provided with a breach for the cable bundle to pass through, then the cable bundle can be routed through the reinforcement member, but the strength of the reinforcement member is degraded
Solution Approach 1:
The arch-shaped part provides a curved, continuous structure that naturally accommodates the cable bundle passage without requiring any breaches. The cable bundle passes through the inner side of the arch, utilizing the curved geometry to achieve easy routing while the continuous arch structure maintains full structural strength.
3Ease of operation
If the reinforcement member is disconnected to accommodate the cable bundle, then the cable bundle can pass through, but the overall strength of the battery pack is degraded
Solution Approach 1:
The low-voltage connection assembly is nested within the arch-shaped reinforcement member, allowing the cable bundle to pass through the inner side of the arch. This nested arrangement eliminates the need to disconnect or separate the reinforcement member, maintaining its integrity and overall strength while providing the necessary passage for electrical connections.
Solution Approach 2:
The arch-shaped configuration provides a continuous, unbroken structure that naturally creates a passage for the cable bundle. The curved geometry allows the low-voltage connection assembly to pass through without requiring disconnection of the reinforcement member, thereby preserving the overall structural strength of the battery pack.
