Quick-Release Battery Chassis Assembly for Collision Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery systems in electric vehicles require complex repair processes and are prone to secondary damage during collisions due to the fixed connection of battery packs to the frame, leading to increased damage in side collisions and pillar impacts.
Innovation Solution
A chassis assembly with multiple mounting positions and a quick-release device controlled by a system, allowing for easy disassembly and maintenance of battery modules, along with a voltage electrical connecting assembly for quick plug-in connections, which can disconnect the battery module from the frame during collisions or thermal runaway events.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery pack is fixedly connected to the frame, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The battery pack is divided into multiple independently replaceable modules. Each module can be quickly removed and replaced without affecting other modules, enabling rapid repair by simply swapping the faulty module rather than disassembling the entire battery pack.
Solution Approach 2:
The connection between the battery pack and frame is made dynamically adjustable through quick-release mechanisms. These mechanisms allow the connection to be easily changed from fixed to detached state, facilitating quick removal and installation of battery modules while maintaining structural stability during normal operation.
2Stability of the object's composition
If the battery pack is fixedly connected to the frame, then the structural stability is improved, but the damage during collision increases
Solution Approach 1:
The quick-release mechanisms enable the battery pack connection to transition from a fixed rigid state to a detachable state during collisions. This dynamic capability allows the battery modules to be quickly separated from the frame to prevent secondary damage from frame deformation and squeezing forces.
Solution Approach 2:
The quick-release mechanisms are pre-configured and ready for immediate activation during collision events. This preliminary preparation ensures that the battery modules can be rapidly detached before significant damage occurs, preventing the transmission of collision forces to the battery cells.
3Stability of the object's composition
If the battery pack is fixedly connected to the frame, then the structural stability is improved, but the repair process complexity increases
Solution Approach 1:
The battery pack is segmented into standardized modules with uniform connection interfaces. This segmentation simplifies the repair process by allowing technicians to remove and replace individual modules without complex disassembly procedures, reducing repair complexity while maintaining structural integrity.
Solution Approach 2:
The quick-release mechanisms and module interfaces are designed with universal compatibility across different battery modules. This universality simplifies the repair process by enabling any module to be replaced with any compatible module using the same connection procedure, eliminating the need for complex module-specific disassembly procedures.
