Integrated Chassis Battery Carrier for Modular Pack Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery systems in vehicles are difficult to assemble and disassemble, require replacement of the entire system for minor defects, and lack a compact, integrated structure that is mechanically stable and compatible with the vehicle body.
Innovation Solution
A vehicle body part is integrally formed with a battery system carrier that accommodates battery cells, including a carrier frame with longitudinal and transverse frames, a battery system cover, and electronic control assemblies, allowing for modular components to be easily attached or detached, providing mechanical stability and a compact structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the entire battery system is replaced for minor defects, then reliability is improved, but loss of substance and manufacturing cost increase
Solution Approach 1:
The battery system is divided into modular battery packs that can be independently replaced. Each battery pack is a self-contained unit with its own housing, battery cells, and connection terminals, allowing defective packs to be replaced without affecting other packs in the system.
Solution Approach 2:
The invention extracts the battery packs as separable modules from the overall battery system. The battery packs can be independently removed and replaced, eliminating the need to replace the entire battery system when only a portion is defective.
2Reliability
If conventional battery systems are assembled, then functionality is achieved, but ease of operation deteriorates due to difficult assembly and disassembly
Solution Approach 1:
The battery system is segmented into standardized modular battery packs that can be easily assembled and disassembled. Each pack has standardized connection terminals and mounting structures that simplify the assembly process and enable quick replacement.
Solution Approach 2:
The battery packs are designed with universal mounting structures and connection interfaces that can be used across different vehicle models and battery system configurations, simplifying assembly procedures and enabling standardized replacement processes.
3Stability of the object's composition
If battery system components are integrated, then mechanical stability is improved, but device complexity increases
Solution Approach 1:
The battery system is organized as an assembly of standardized battery packs rather than a fully integrated monolithic structure. This segmentation provides mechanical stability through standardized mounting while maintaining manageable complexity through modular design.
Solution Approach 2:
Each battery pack integrates multiple components (battery cells, housing, connection terminals, and protection circuits) into a single modular unit. This merging within packs provides mechanical stability while the modular nature keeps overall system complexity manageable.
