Modular Battery Pack Mounting for Utility Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for improved battery assemblies for electric vehicles that can be easily mounted and serviced, particularly for utility vehicles, which require modular designs to reduce installation complexity and enhance service access without the need to raise the vehicle.
Innovation Solution
A modular battery assembly with a housing, battery units, and a mounting system that allows for separate units to be connected and positioned relative to the vehicle, featuring access panels for easier maintenance and a mounting system that secures the assembly below the vehicle frame, enabling flexible installation and service without lifting the vehicle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If battery packs are mounted as a single large unit under the vehicle, then the vehicle can be propelled effectively, but the mounting process becomes complex and requires raising the vehicle to allow sufficient ground clearance for installation
Solution Approach 1:
The battery assembly is divided into multiple separate battery packs (first battery pack, second battery pack, etc.) that can be mounted independently. Each battery pack has its own housing and mounting system, allowing them to be installed separately without requiring the vehicle to be raised for complex single-unit installation. The housing connection portions enable these separate packs to be connected later to form the complete battery assembly.
2Ease of repair
If battery packs are designed as integrated units, then structural strength is maintained, but service access becomes difficult requiring vehicle elevation or complete removal of battery assemblies
Solution Approach 1:
The battery assembly is segmented into multiple independent battery packs housed in separate housings. Each housing can be accessed independently for servicing its contained battery pack, eliminating the need to raise the vehicle or remove entire battery assemblies. The housing connection portions maintain structural integrity while allowing independent access to each battery pack through access panels.
Solution Approach 2:
Access panels are positioned on the upper portions of the housings rather than requiring access from below. This vertical arrangement allows service personnel to access battery packs from above the vehicle frame, eliminating the need to raise the vehicle for maintenance while preserving the strength of the housing structure.
3Ease of operation
If multiple battery units are distributed across lateral portions of the housing, then service access is improved, but the housing structure becomes more complex requiring connection portions to span across medial sides
Solution Approach 1:
The housing is divided into distinct lateral portions (first lateral portion, second lateral portion, etc.) separated by medial sides. Each lateral portion contains its own battery units and can be accessed independently. The housing connection portions are designed to span across the medial sides to connect these lateral portions, creating a modular structure that improves service accessibility while maintaining organizational simplicity.

AI summary
A battery assembly for an electric vehicle is provided that has a housing, one or more battery units, and a mounting system. The housing includes a concave shell extending from an upper portion of the housing toward a bottom portion of the housing. The concave shell is disposed around an internal space. A cover is coupled with an edge of the concave shell. The one or more battery units are disposed within the internal space of the housing. The mounting system is for connecting the battery assembly to a vehicle frame.
