Battery Module Spacer Assembly for Coolant Flow Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The complex and bulky spacers in existing battery modules for motor vehicles complicate assembly and handling, making the manufacturing and mounting process difficult, while also requiring precise alignment and compression to maintain temperature control fluid flow paths.
Innovation Solution
A battery module design featuring a holding device with axially sliding spacers and retaining means that include a main body, spacers with integral separator plates, and axial clamping mechanisms, allowing for simplified assembly and secure fixation of battery cells and separator plates, while maintaining temperature control fluid flow paths through the use of sliding connections and baffle structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional spacers with separate mounting portions and separator plates are used, then temperature control fluid flow paths can be maintained, but the assembly process becomes complex and handling becomes difficult
Solution Approach 1:
The mounting portion and separator plate are integrally formed as a single spacer component, eliminating the need for separate assembly steps and reducing structural complexity while maintaining the temperature control fluid flow path separation function
Solution Approach 2:
The integral spacer serves multiple functions simultaneously: it acts as a mounting support for battery cells, a separator for temperature control fluid passes, and a structural element for maintaining cell spacing, thereby simplifying the overall assembly process
2Stability of the object's composition
If traditional bulky spacers are used, then battery cells can be properly spaced and secured, but handling during mounting becomes difficult
Solution Approach 1:
The battery module is divided into modular units with individual spacers that can be independently handled and installed, reducing the bulk and improving handling ease while maintaining proper battery cell spacing
Solution Approach 2:
The mounting foot and separator plate are merged into a single integral spacer structure, reducing overall bulk while maintaining the necessary spacing and positioning functions for battery cells
3Strength
If axial clamping means are used to compress battery cells, then secure fixation is achieved, but the structure requires additional components
Solution Approach 1:
The axial stop and clamping function are integrated into the existing spacer structure, providing secure battery cell fixation through axial compression without requiring separate clamping components
Solution Approach 2:
The axial stop serves multiple functions: it provides the clamping force for secure battery cell fixation, maintains proper spacing, and guides the assembly process, thereby reducing the need for additional components

Implementation Method 1
the mounting feet being slidably mounted parallel to the axis X on the main body in at least one row and thus defining a sliding connection therebetween
Implementation Method 2
the retaining means comprising axial clamping means, which axially compress the second axial stop against the battery cell located at the second axial end of the row of battery cells

AI summary
A battery module includes a row of battery cells arranged parallel to each other, aligned along a longitudinal axis, and arranged at a distance from each other so that adjacent battery cells define a gap allowing a temperature control fluid to pass therethrough. A holding device includes a main body, a plurality of spacers and retaining means. Each spacer includes a mounting foot and a separator plate integrally formed with the mounting foot. The separator plate is arranged in the gap and configured to separate a first pass and a second pass of the temperature control fluid. The mounting feet are slidably mounted parallel to the longitudinal axis, defining a sliding connection. The retaining means includes axial clamping means which axially compresses an axial stop of the retaining means against a battery cell located at an axial end of the row of battery cells.
