Battery Module Side Plate Ribs With Notches for Easy Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing battery module disassembly process is hindered by the absence of gaps between side plates and mounting beams, and the fixed connection of liquid cooling plates, making it difficult to insert disassembly tools without damaging the cooling plates or accessing the module from the sides.
Innovation Solution
The battery module design incorporates protruding rib portions with notches on the side plates, allowing a gap between the side plates and the mounting beam for tool insertion and enabling easy disassembly, while maintaining structural integrity through evenly distributed lifting lugs and enhanced rib arrangements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If lifting lugs are arranged on the reinforcing ribs of the side plates, then the structural strength is improved, but the gap between the side plates and mounting beam disappears making disassembly difficult
Solution Approach 1:
The side plate is segmented into multiple reinforcing ribs, and lifting lugs are distributed on these ribs. The notches create segmented access points that allow disassembly tools to reach the lifting lugs without requiring a continuous gap between the side plate and mounting beam.
Solution Approach 2:
The notches act as intermediaries that provide access pathways for disassembly tools. These notches enable the tool to reach the lifting lugs on the reinforcing ribs without requiring direct access from the side plate exterior, thus resolving the contradiction between maintaining structural integrity and enabling disassembly.
2Productivity
If the liquid cooling plate is fixedly connected to the bottom of the end plate, then the cooling efficiency is improved, but the disassembly tool cannot easily lift the battery module from the bottom
Solution Approach 1:
The end plate is divided into multiple reinforcing ribs that extend from the side plates. The notches created in these ribs provide access points that allow disassembly tools to reach the lifting lugs on the bottom side of the module, enabling disassembly without removing the fixed liquid cooling plate.
Solution Approach 2:
The notches create vertical access pathways through the reinforcing ribs, allowing disassembly tools to approach the lifting lugs from a different spatial dimension (through the rib structure rather than from the exterior bottom surface), thus enabling disassembly while maintaining the fixed cooling plate connection.
3Strength
If the protruding rib portion extends continuously without notches, then the structural integrity is improved, but the disassembly tool cannot be inserted to lift the battery module
Solution Approach 1:
The continuous protruding rib portion is segmented by introducing notches at specific locations. These notches create discrete access points that allow disassembly tools to be inserted without compromising the overall structural integrity of the rib system, as the notches are strategically positioned to maintain load-bearing capacity.
Solution Approach 2:
The notches are introduced locally at specific positions on the protruding rib portion where access is needed, while the rest of the rib structure maintains its continuous, load-bearing configuration. This localized modification allows tool insertion without affecting the global structural integrity of the side plate assembly.

AI summary
A battery module includes a casing (1) and a cell assembly (2). The casing (1) includes two side plates (11) opposite to each other. Each of the side plates (11) includes a side plate body (111), a protruding rib portion, and lifting lugs (113). The protruding rib portion is disposed on an outer side surface of the side plate body (111) and extends in a length direction of the side plate body (111). The protruding rib portion includes a protruding rib and a notch (114), and the protruding rib and the notch (114) are adjacent to each other in an extending direction of the protruding rib portion. The notch (114) is provided on at least one end of the protruding rib portion in the extending direction. The lifting lugs (113) are disposed on the protruding rib at intervals in the extending direction of the protruding rib portion.
