Battery Pack Case Wiring Routing to Avoid Combustion Damage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery assembly containers are prone to cable damage during battery combustion, leading to insulation failure and obstruction in wiring operations, which complicates the reliable and prompt provision of wiring lines.
Innovation Solution
A battery pack case design featuring a metal base frame with a box body and lid, where wiring lines are positioned to avoid crossover with electrically conductive members, allowing for safe and unobstructed connection and identification, even in the event of partial combustion, and includes a terminal frame and vacuum sensor placement to enhance operational efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are provided adjacent to the lid of the battery assembly container for electrical connection, then electrical connectivity is achieved, but the cables are easily affected by combustion and insulation cannot be maintained
Solution Approach 1:
The patent relocates cable entry points from the vertical lid area to the horizontal base frame area, changing the spatial dimension of cable routing. This dimensional shift moves cables away from the combustion-prone lid region to a safer base location, reducing combustion impact while maintaining electrical connectivity functionality
2Adaptability or versatility
If multiple wiring lines are provided inside and outside the battery assembly container for heaters and sensors, then operational functionality is achieved, but wiring operations become complex and time-consuming
Solution Approach 1:
The patent combines multiple cable entry points and wiring routes into a unified base frame structure. By consolidating cable management functions at the base frame rather than distributing them across multiple locations including the lid, the patent simplifies wiring operations while maintaining all necessary connections for heaters, sensors, and electrical terminals

AI summary
This invention pertains to a battery-pack case. Said battery-pack case (10) comprises the following: a metal base (12); a container (14) that has an opening in the top surface thereof, accommodates a battery pack, and is affixed to the metal base (12); a lid (16) that closes the opening in the container (14); a positive-electrode busbar (42) and a negative-electrode busbar (52) provided on an exterior surface of the container (14), with a conductive member (62) connected to each of said busbars; and a plurality of wires (130) that lead inside the container (14) from the outside thereof. Said wires (130) are routed between the positive-electrode busbar (42) and the negative-electrode busbar (52) so as not to interfere with the aforementioned conductive members (62).
