Modular EV Battery Pack with Bottom Access for Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current battery packs in electric vehicles are not easily modifiable, as they are mounted as an integral structure, making it difficult to replace malfunctioning battery modules without complex disassembly and high costs.
Innovation Solution
A modular battery pack design with a support part that allows battery modules to be separately mounted and removed through openings on the bottom or sides, using mounting flanges and fasteners, enabling convenient replacement without disassembling the entire pack.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If battery modules are mounted as an integral structure, then structural stability is improved, but ease of repair deteriorates
Solution Approach 1:
The battery pack is divided into multiple independently replaceable battery modules (first battery module, second battery module, etc.) that can be separately removed and replaced through openings in the support part, while the overall pack structure remains stable through the support part design
2Ease of manufacture
If battery modules are mounted as an integral structure, then manufacturing simplicity is improved, but device complexity increases
Solution Approach 1:
The battery pack采用模块化设计，将电池组分为多个可独立更换的电池模块，每个模块可通过支撑部件的开孔单独安装和拆卸，实现了结构的模块化
Solution Approach 2:
支撑部件设计为通用结构，可容纳多个不同类型的电池模块，开孔设计使得同一支撑部件可用于不同的电池模块配置，提高了部件的通用性
3Strength
If battery modules are mounted as an integral structure, then structural integrity is improved, but ease of operation deteriorates
Solution Approach 1:
The battery pack is segmented into modular units that can be individually accessed through openings in the support part, allowing easy removal and replacement of specific battery modules without disassembling the entire pack structure
Solution Approach 2:
The battery modules are extracted from the integral structure and can be individually removed through openings in the support part, enabling easy access and replacement while the support part maintains the overall structural integrity

AI summary
Provided are systems and methods for configuring battery packs in electric vehicles. A battery pack may include a plurality of battery modules, a support part, and at least one opening provided on the support part. The support part may be provided with a bottom for supporting the plurality of battery modules, sides, a top, and an accommodation space formed by the bottom, the sides, and the top for accommodating the plurality of battery modules. The opening provided on the bottom of the support part may enable the plurality of battery modules to be passed through the at least one opening and be detachably mounted to the bottom of the support part so as to be supported by the bottom.
