Power Storage Valve Venting With Electrolyte Reservoir Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pressure-regulating valves for power storage modules face challenges in timely discharge of electrolytes, leading to potential short circuits between cells due to accumulated electrolytes.
Innovation Solution
The pressure-regulating valve includes a valve body portion that opens in response to pressure to release pressure in the power storage module, and an electrolyte reservoir portion that stores leaking electrolytes, configured as a separate member from the valve body portion and formed into a plate shape with air chambers and a flow path to facilitate electrolyte discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple valve bodies are provided in one discharge port, then pressure regulation capability is improved, but electrolyte discharge speed deteriorates
Solution Approach 1:
The invention divides the single discharge port into multiple independent discharge ports, each with its own valve body. This segmentation allows electrolyte to be discharged through multiple parallel pathways simultaneously, significantly increasing the overall discharge speed while maintaining the pressure regulation capability of multiple valve bodies.
2Reliability
If multiple valve bodies are provided in one discharge port, then pressure regulation capability is improved, but short circuit risk increases
Solution Approach 1:
By segmenting the single discharge port into multiple independent discharge ports, the invention isolates the electrolyte discharge paths. This prevents accumulated electrolyte from causing short circuits between multiple valve bodies, as each valve body has its own dedicated discharge pathway.

AI summary
A pressure-regulating valve for a power storage module includes a valve body portion that opens in response to pressure in a power storage module to release the pressure in the power storage module, and an electrolyte reservoir portion provided between the valve body portion and the power storage module, and capable of storing the electrolyte leaking from an inside of the power storage module to a valve body portion side.
