Battery Module Power Distribution Unit Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle battery boxes face efficiency issues during maintenance, particularly when connector connections between the electric component body and loads/battery are difficult to access, leading to lowered operation efficiency.
Innovation Solution
A battery module design featuring a power distribution unit with a base and device mounting portion, where the base includes battery and load connection portions positioned for easy access, allowing the device mounting portion to be removed without accessing the battery or load connections, thus improving maintenance efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electric component body is integrated with the battery box and connector connections are located at difficult-to-access positions, then the structural compactness is improved, but the maintenance operation efficiency deteriorates
Solution Approach 1:
The power distribution unit is segmented into a base and a device mounting portion that can be separated. The device mounting portion containing the electric component body can be independently removed from the base, allowing maintenance without disconnecting battery or load connections. This segmentation resolves the contradiction by enabling easy maintenance while maintaining integrated structure during normal operation.
Solution Approach 2:
The device mounting portion is extracted as a separate removable module from the base. This extracted portion contains the electric component body and can be removed independently, allowing technicians to access and replace components without dealing with the battery connections or load connections that remain mounted on the base.
2Volume of moving object
If the connector connections between the electric component body and battery/load are located at difficult-to-access positions, then the space utilization is improved, but the maintenance time increases
Solution Approach 1:
The power distribution unit is divided into a base with battery/load connections and a separate device mounting portion. This segmentation allows the device mounting portion to be removed quickly for maintenance without requiring access to the battery or load connections, significantly reducing maintenance time while maintaining compact space utilization.
Solution Approach 2:
The device mounting portion is extracted as a removable module, separating it from the base that contains the battery and load connections. This extraction enables rapid removal and replacement of the device mounting portion during maintenance, eliminating the time-consuming process of accessing difficult-to-reach connector connections.
3Productivity
If the device mounting portion is made detachable from the base, then the maintenance efficiency is improved, but the device complexity increases
Solution Approach 1:
The power distribution unit is segmented into a base and a device mounting portion connected through a support structure. This segmentation enables the device mounting portion to be detached for efficient maintenance while adding minimal structural complexity through the use of a straightforward support and connection mechanism.
