Battery Module Support Structure for Easy Pack Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inconvenient disassembly of batteries restricts online rework, after-sales services, and recycling, particularly in Cell to Pack technology, leading to increased maintenance difficulties and costs, as well as limitations in energy density and recyclable components.
Innovation Solution
A battery design featuring an accommodating box with a support portion and connecting portion that allows the battery module to be independently fixed within the box body, eliminating the need for bonding to the box bottom, enabling easy disassembly and improved structural stability and anti-expansion capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery module is bonded to the box bottom for fixed connection, then the structural stability is improved, but the disassembly convenience deteriorates
Solution Approach 1:
The support portion is divided into a fixed base part integrated with the box body and a detachable connecting part that interfaces with the battery module. This segmentation allows the connection to be made and undone without damaging components, resolving the contradiction between stable fixation and easy disassembly.
Solution Approach 2:
The support portion acts as an intermediary component between the box body and the battery module. It provides a standardized interface that enables stable mechanical support while allowing for convenient insertion and removal of the battery module, thus solving both stability and disassembly convenience requirements.
2Ease of operation
If the battery module is independently fixed within the box body, then the disassembly convenience is improved, but the structural stability may deteriorate
Solution Approach 1:
The support portion is pre-integrated into the box body during manufacturing, establishing a stable structural foundation before the battery module is installed. This preliminary action ensures that the box body maintains its structural integrity while enabling convenient battery module installation and removal.
3Ease of repair
If the box cap is detachably arranged, then the maintenance accessibility is improved, but the sealing reliability may deteriorate
Solution Approach 1:
The accommodating box is segmented into a fixed box body and a detachable box cap, allowing the cap to be removed for maintenance while the main structure remains intact. This segmentation enables easy access to internal components while maintaining overall structural stability.

AI summary
A battery includes an accommodating box and a battery module. The accommodating box includes a box body, a box cap, and a box bottom. The box cap and the box bottom are connected with two opposite ends along a first direction of the box body, the box cap is detachably arranged, a cavity is provided in the box body, and the box body is provided with a support portion. The battery module is provided in the cavity and includes an accommodating member and at least two battery cells fixed in the accommodating member. The accommodating member is provided with a connecting portion. The connecting portion is pressed onto a surface of the support portion facing the box cap and is supported by the support portion, and is fixedly connected with the support portion, to realize supporting and fixing of the box body to the battery module.
