Segmented Pressure Adjustment Valve for Battery Electrolyte Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure adjustment valves for power storage modules often discharge electrolyte along with gas, leading to accumulation and potential short circuits due to multiple valve bodies sharing a single discharge port, making it difficult to discharge electrolyte without disrupting the flow.
Innovation Solution
A pressure adjustment valve with isolated valve body portions, each having a dedicated discharging portion, preventing contact and short circuits by ensuring independent discharge of electrolyte and gas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If multiple valve bodies share a single discharge port, then the device complexity is reduced, but electrolyte accumulates inside the valve bodies causing short circuits
Solution Approach 1:
The pressure adjustment valve is divided into multiple independent valve body portions (first, second, third valve body portions), each with its own isolated internal space and discharge port. This segmentation allows electrolyte to be discharged separately from each valve body without accumulating and causing short circuits between multiple cells, while maintaining relatively simple overall device structure.
2Ease of manufacture
If a single discharge port is used for multiple valve bodies, then the manufacturing process is simplified, but electrolyte discharge is disrupted
Solution Approach 1:
Each valve body portion is equipped with a dedicated discharge port, enabling independent and uninterrupted electrolyte discharge from each section. This segmentation improves electrolyte discharge efficiency and prevents flow disruption, while the modular design maintains manufacturing simplicity through standardized components.
3Productivity
If valve bodies are isolated from each other, then electrolyte discharge is improved, but the device complexity increases
Solution Approach 1:
The valve is segmented into multiple isolated valve body portions with separate internal spaces, improving electrolyte discharge efficiency by preventing accumulation. The segmentation is implemented in a modular manner that limits complexity increase, with each portion following a similar structural pattern.
Solution Approach 2:
Each valve body portion serves multiple functions: pressure regulation for its associated cell, gas discharge, and electrolyte discharge. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while improving electrolyte discharge efficiency.
