Battery Wiring Module Grouping for Wire Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As the number of batteries in a battery assembly increases, the size of the battery wiring module grows due to the need for more voltage detection lines, requiring larger arrangement spaces and longer wire lengths, which complicates size reduction and wire management.
Innovation Solution
The battery wiring module divides batteries into groups, with voltage detection lines connected through electric wire outlets to a control unit, reducing the need for extensive wire arrangement spaces and minimizing wire lengths by positioning outlets close to connection points, forming a gutter-shaped electric wire arrangement part with cutouts for outlets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the number of batteries in a battery assembly increases to enhance output power, then the power supply capability is improved, but the number of voltage detection lines increases requiring larger arrangement spaces and longer wire lengths which complicates size reduction and wire management
Solution Approach 1:
The patent divides the battery assembly into multiple stacks, with each stack containing a subset of batteries. This segmentation allows the voltage detection system to be organized hierarchically, reducing the complexity of wire arrangement while maintaining the ability to monitor all batteries in the assembly.
Solution Approach 2:
The patent introduces a holding member as an intermediary component that integrates multiple voltage detection lines and connects them to the control unit. This holding member serves as a consolidation point, simplifying wire management by bundling and organizing the detection lines rather than having them individually routed throughout the entire battery assembly.
2Power
If the number of batteries in a battery assembly increases to enhance output power, then the power supply capability is improved, but the arrangement space for voltage detection lines increases causing the battery wiring module to become larger
Solution Approach 1:
By segmenting the battery assembly into stacks and organizing voltage detection lines within each stack, the patent reduces the spatial requirements for wire arrangement. The holding member further consolidates these lines, enabling compact integration that prevents the wiring module size from scaling linearly with the number of batteries.
Solution Approach 2:
The holding member serves multiple functions: it holds and organizes voltage detection lines, provides structural support, and facilitates connection to the control unit. This multi-functionality reduces the need for separate components, thereby minimizing the overall size of the battery wiring module while accommodating increasing numbers of batteries.
3Power
If the number of batteries in a battery assembly increases to enhance output power, then the power supply capability is improved, but the wire length of voltage detection lines increases leading to wire savings becoming more important
Solution Approach 1:
Segmenting the battery assembly into stacks allows voltage detection lines to be routed more efficiently within each stack rather than spanning the entire assembly. This reduces the average length of detection lines required while still enabling monitoring of all batteries.
Solution Approach 2:
The holding member acts as a centralized connection point that consolidates multiple voltage detection lines. By routing lines through this intermediary rather than having them individually connect to distant points on the control unit, the total wire length is reduced while maintaining full monitoring capability.

AI summary
A battery wiring module includes: connection members electrically connecting adjacent positive and negative electrodes in an electrode row of a battery assembly; voltage detection lines connecting the connection members and a control unit; and a holding member holding the connection members and the voltage detection lines, and including an electric wire arrangement part in which the voltage detection lines are arranged and which includes electric wire outlets. The batteries are divided into groups so as to correspond to the electric wire outlets, respectively, such that the voltage detection lines belonging to one of the groups are pulled out from the electric wire arrangement part toward the control unit through the corresponding one of the electric wire outlets.
