Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a simple, reliable, and effective solution to measure variations in the intensity of currents flowing through the phase connectors or battery connectors in electric or hybrid vehicle electrical assemblies, particularly in high-voltage power battery systems.
Innovation Solution
An electrical connection bar with a flat base and orthogonally extending conductive fixing portions and connection pins, allowing direct contact with the electronic control unit to measure current intensity variations, is designed. The connection bar is preferably made of conductive materials like copper, steel, or aluminum, with an anti-corrosion surface and features that facilitate easy manufacturing and secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional electrical connection structure is used, then the electrical connection is simple, but the current intensity measurement capability is lacking
Solution Approach 1:
The connection bar serves multiple functions: it provides electrical connection between the electronic power module and control unit, enables current intensity measurement through its conductive structure, and offers mechanical support. The same structural elements (conductive body and contact surfaces) fulfill both connection and measurement functions without requiring separate dedicated components.
Solution Approach 2:
The invention merges the electrical connection function and measurement function into a single integrated connection bar structure. The conductive body that establishes electrical connection also serves as the measurement path for current intensity, combining what would traditionally be separate functions into one unified component.
