Refractory Line Clip for High-Voltage Battery Thermal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing high-voltage battery lines in motor vehicles are time-consuming and costly, and the lines are vulnerable to damage from hot gases emitted through degassing openings of battery cells, which can reach temperatures up to 1200°C.
Innovation Solution
A line installation device featuring line clips made from refractory materials that guide electrical and coolant lines over the sides of battery modules, specifically designed to protect the lines from hot gases by encasing them in a heat-resistant material and using a snap-action connection for easy assembly and replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If lines are individually mounted on the high-voltage battery, then the lines can be installed on the battery modules, but the mounting process becomes time-consuming and costly
Solution Approach 1:
The patent combines multiple lines (electrical lines and coolant lines) into a single line bundle that is mounted together on the battery module. The line bundle includes multiple lines that are grouped and secured as one unit, reducing the number of separate mounting operations required and thereby decreasing installation time and cost.
2Ease of operation
If lines are arranged on the top side of battery modules, then the lines can be accessible, but they become vulnerable to hot gas from degassing openings
Solution Approach 1:
The patent introduces a protective sleeve or sheath as an intermediary component that surrounds the lines in the line bundle. This protective covering acts as a barrier between the lines and the hot gas emanating from the degassing openings, allowing the lines to remain accessible while protecting them from thermal damage.
3Productivity
If multiple lines are bundled together, then installation efficiency improves, but the complexity of protecting all lines from hot gas increases
Solution Approach 1:
Instead of providing separate protective measures for each individual line, the patent combines all lines into a single bundled structure with a common protective sleeve. This unified approach maintains installation efficiency while simplifying the protective structure, as one sleeve protects multiple lines simultaneously rather than requiring multiple separate protection systems.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution allows for simpler and more efficient line installation with reduced space requirements, protecting the lines from hot gas damage and minimizing mounting expenditure while maintaining precise line positioning.
Implementation Method 1
The at least one line clip contains a refractory material for protecting the lines against a hot gas which passes out of the degassing openings

AI summary
A line installation device is provided for a high-voltage battery of a motor vehicle for installing lines of the high-voltage battery on at least one battery module of the high-voltage battery. At least one line clip retains at least one first line in the form of an electrical line and retains at least one second line in the form of a coolant line. The line clip is designed to guide the lines as a line bundle over a side of the at least one battery module having degassing openings of battery cells of the at least one battery module. The line clip has a refractory material for protecting the lines against a hot gas passing out of the degassing openings.
