Battery Pack Crossmember Mount for Load Distribution and Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric vehicle battery packs experience forces beyond threshold values, leading to movement or changes that hinder their performance and that of the vehicle, due to uneven terrain or impact forces.
Innovation Solution
A battery pack mount apparatus with three members - a first member extending across the pack, and second and third members extending halfway across, providing structural support and defining compartments for battery modules, distributing loads and allowing space for coolant manifolds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a three-member mount apparatus is used to increase structural support and force threshold, then the battery pack can withstand higher forces and maintain stability, but the device complexity increases due to the additional members and compartments
Solution Approach 1:
The mount apparatus is divided into three separate members (first member extending across the battery pack, second member at the first end, third member at the second end) that work together to distribute and bear forces. This segmentation allows each member to be optimized for its specific function while collectively providing enhanced structural support and force resistance.
2Stability of the object's composition
If members are extended to provide structural support and define compartments, then the battery pack stability improves, but the weight of the mount structure increases
Solution Approach 1:
The mount apparatus members serve multiple functions: the first member provides longitudinal structural support and defines compartment boundaries, while the second and third members provide transverse support and additional compartment definition. This multi-functionality allows the structure to achieve enhanced stability without requiring separate dedicated components for each function, thereby controlling weight.

AI summary
An apparatus that can define at least one compartment in a battery pack to receive a battery module is disclosed. The apparatus can include a first member that extends from the first side of the battery pack to the second side of the battery pack. The apparatus can include a second member and a third member that together run cross car and extend from the first side to the second side of the battery pack, except with a gap between the second member and the third member.
