Battery Pack Housing Assembly With Pressure-Relief Valve Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage power supplies are prone to damage and reduced connection stability due to high-pressure fluid passing through the battery pack, which affects the service life and increases material costs, process difficulty, and volume.
Innovation Solution
A housing assembly with a first support that includes a supporting structure to orient the explosion-proof valve towards a pressure relief space, allowing ejected substances to flow out without increasing material costs or volume, and a module-free fixing structure that integrates the battery cell directly into the housing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thermal insulation materials are added to the battery module, then the spread duration of battery thermal runaway is prolonged and maximum temperature is reduced, but material costs and process difficulty increase
Solution Approach 1:
The patent extracts the harmful high-pressure fluid from the battery module by providing a dedicated discharge channel that directs it to a safe external location. This eliminates the need for thermal insulation materials while maintaining safety, as the fluid is removed rather than contained or insulated against.
Solution Approach 2:
The patent introduces a discharge channel as an intermediary structure that mediates between the battery module and the external environment. This channel safely conducts the high-pressure fluid away from sensitive components, providing a controlled path that eliminates the need for complex insulation systems.
2Temperature
If liquid cooling technology and endothermic phase change material technology are used, then heat removal efficiency is improved, but material costs, process difficulty, volume and weight increase
Solution Approach 1:
The patent extracts the harmful high-pressure fluid from the battery module by providing a dedicated discharge channel that directs it to a safe external location. This eliminates the need for thermal insulation materials while maintaining safety, as the fluid is removed rather than contained or insulated against.
3Temperature
If high-pressure fluid passes through the battery pack, then cooling effect is achieved, but the battery pack is prone to damage and connection stability decreases
Solution Approach 1:
The patent introduces a discharge channel as an intermediary structure that mediates between the battery module and the external environment. This channel safely conducts the high-pressure fluid away from sensitive components, providing a controlled path that protects the battery pack from damage while maintaining the cooling effect.
Solution Approach 2:
The patent extracts the harmful high-pressure fluid from the battery module by providing a dedicated discharge channel that directs it to a safe external location. This eliminates the need for thermal insulation materials while maintaining safety, as the fluid is removed rather than contained or insulated against.
4Reliability
If module structure is used with separate mounting space, then battery cell can be securely mounted, but volume of energy storage power supply increases
Solution Approach 1:
The patent merges the support structure with the housing by making the support an integral part of the housing structure. This integration eliminates separate mounting components and reduces overall volume while maintaining secure battery cell mounting, as the housing itself provides the necessary support and fixation.
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 provides rapid pressure relief, enhances connection stability, reduces the volume and weight of the energy storage power supply, and improves energy density without additional costs.
Implementation Method 1
substances ejected from the first explosion-proof valve can enter the pressure relief space and flow out of the battery pack to an external environment, promptly reducing pressure in the battery cell

AI summary
Provided are a housing assembly, a battery pack, and an energy storage power supply. The housing assembly includes a housing having a receiving chamber. The receiving chamber is provided with a first support at an inner wall of the receiving chamber. The first support is configured for mounting a battery cell provided with a first explosion-proof valve. The first support is provided with a supporting structure configured to support the battery cell and allow a spacing to be formed between the first explosion-proof valve and the inner wall of the receiving chamber to form a pressure relief space. The pressure relief space is in communication with the receiving chamber. A valve port of the first explosion-proof valve is oriented towards the pressure relief space.
