Battery Module Voltage Sensing Fuse Layout for Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules face challenges in providing voltage detection portions and fuses in a spatially efficient manner due to the required space for both components, which can be substantial.
Innovation Solution
A voltage detection device is integrated with a holding body and a conductor that functions as a fuse, allowing for compact integration by offsetting the tip end of the detection portion to avoid overlapping with the bonding area of the leads, thereby optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a voltage detection portion and a fuse are provided as separate components in a battery module, then each component can be independently designed and installed, but the total space required for both components becomes relatively large
Solution Approach 1:
The patent combines the voltage detection portion and the fuse into a single integrated structure where the conductor serves dual purposes: as part of the voltage detection circuit and as a fuse element. This merging eliminates the need for separate installation spaces for both components, directly resolving the space constraint while maintaining both voltage detection and overcurrent protection functions
Solution Approach 2:
The conductor in the patent is designed to perform multiple functions simultaneously: it acts as an electrical connection element, a voltage detection element, and a fuse element. This multi-functionality allows the battery module to achieve voltage monitoring and overcurrent protection without requiring separate dedicated components, thereby reducing the overall space requirement
