Solution Overview
Problem
Existing vehicle battery systems face challenges in securely and safely accommodating batteries in varying vehicle designs, particularly in preventing electrolyte leakage when batteries are placed in passenger or luggage compartments, and require solutions for secure handling and insulation from temperature fluctuations.
Innovation Solution
A multi-layered battery pouch with an absorbent layer containing a base and an outer impervious layer, featuring a wedge for secure attachment to a tray, extended side walls for splash prevention, and handles for easy lifting, which includes a semi-permeable membrane to neutralize acidic electrolytes and maintain insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a battery is placed in passenger or luggage compartments with varying vehicle designs, then the battery system must be adaptable to different locations, but the security and safety of battery containment becomes more difficult to ensure
Solution Approach 1:
The pouch structure serves multiple functions simultaneously: it contains the battery, absorbs electrolyte leakage through the base-impregnated absorbent layer, provides thermal insulation, and secures the battery through integrated wedge engagement. This multi-functional design allows the same structure to adapt to various vehicle locations while maintaining consistent safety and security performance.
Solution Approach 2:
The pouch employs composite material construction with an outer impervious layer (such as polyethylene or polypropylene) combined with an absorbent layer impregnated with base materials. This composite structure provides both leakage containment and neutralization capabilities, ensuring reliable battery containment across different vehicle designs and locations.
2Object-affected harmful factors
If the pouch includes an absorbent layer impregnated with base to neutralize acid, then electrolyte leakage is neutralized, but the device complexity increases
Solution Approach 1:
The pouch merges the containment function and the neutralization function into a single integrated structure. The outer impervious layer and the base-impregnated absorbent layer are combined in one pouch component, eliminating the need for separate containment and neutralization systems. This reduces overall device complexity while maintaining effective electrolyte leakage neutralization.
Solution Approach 2:
The base-impregnated absorbent layer acts as an intermediary between the electrolyte and the external environment. When electrolyte leakage occurs, the base materials (such as calcium carbonate, magnesium carbonate, or sodium bicarbonate) in the absorbent layer neutralize the acid before it can cause harm, providing a simple yet effective solution to the harmful factor.
3Object-affected harmful factors
If extended side walls are used for splash prevention, then electrolyte splash is prevented, but the volume and weight of the pouch increase
Solution Approach 1:
The pouch utilizes flexible thin-film construction with extended side walls that provide splash prevention without adding significant weight. The impervious outer layer forms a lightweight barrier that contains and directs electrolyte, preventing splash while maintaining minimal weight increase compared to rigid containment structures.

AI summary
A battery system of a vehicle includes a battery, a battery tray configured to support the battery, and a battery pouch. The pouch has a plurality of side walls and a bottom defining a space sized to accommodate the battery. The side walls each include an absorbent layer containing a base, such as sodium bicarbonate, and an outer layer impervious to the electrolyte and the base. One of the side walls is a front side wall that includes a wedge that is configured to mate with a front of the battery and the tray. The wedge cooperates with a bottom lip of the battery to secure the battery to the tray.
