Hydrogen Flow Distribution for Pressure-Balanced Vehicle Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hydrogen fuel cell electric vehicle filling systems face inefficiencies due to insufficient infrastructure, high construction and management costs, and degraded filling performance when pressures across multiple receptacles are imbalanced.
Innovation Solution
A fluid distributing apparatus that adjusts the flow rates of fluids from multiple receptacles using valves and controllers to equalize pressures and ensure uniform discharge into a storage tank, incorporating features like differential pressure measurement and pressure-adjusting valves.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple receptacles are used for rapid filling, then filling speed is improved, but filling performance degrades when pressure imbalance occurs between receptacles
Solution Approach 1:
The patent changes the pressure parameter dynamically by introducing a pressure equalization passage that allows pressure to equalize between receptacles. This resolves the contradiction by maintaining reliable filling performance across all receptacles while preserving the high productivity benefit of multiple receptacles for rapid filling
2Quantity of substance
If hydrogen is introduced from multiple receptacles into a single manifold, then filling capacity is improved, but pressure imbalance causes degraded filling performance
Solution Approach 1:
The patent introduces a pressure equalization passage as an intermediary element between the manifold and receptacles. This mediator allows pressure to be balanced across all receptacles, ensuring uniform filling performance while maintaining the increased hydrogen filling capacity provided by multiple receptacles
