Modular Armored Battery Box for Protected Vehicle Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery boxes in military vehicles are vulnerable to projectile impacts and fires, and traditional armor solutions increase weight, alter the vehicle's silhouette, and complicate battery access.
Innovation Solution
A modular battery box design with removable armor plates that can be secured internally without altering the external shape, featuring connecting tabs and an interface plate for easy access and adjustable protection, along with sliding drawers for battery placement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If armor plates are added to protect the battery box, then protection against projectile impacts is improved, but the vehicle weight increases
Solution Approach 1:
The battery box is divided into modular compartments with individual armor plates for each battery unit. This segmentation allows protection to be applied only where needed rather than covering the entire battery box, reducing overall weight while maintaining essential protection levels.
Solution Approach 2:
Armor plates are selectively positioned at specific high-risk areas of the battery box based on threat assessment and impact probability. This local quality approach ensures that protection is concentrated where most needed, optimizing the protection-to-weight ratio by avoiding unnecessary armor in low-risk zones.
2Object-affected harmful factors
If armor plates are added to protect the battery box, then protection against projectile impacts is improved, but the vehicle's external silhouette is altered
Solution Approach 1:
The armor plates are designed to nest within the existing battery box structure rather than protruding outward. The armor elements are integrated into the compartment walls and lids in a space-efficient manner that provides protection without changing the vehicle's external轮廓, maintaining stealth characteristics.
3Object-affected harmful factors
If armor plates are added to protect the battery box, then protection against projectile impacts is improved, but access to batteries becomes more difficult
Solution Approach 1:
The battery box is segmented into multiple independent compartments, each with its own removable armor lid. This allows operators to access specific batteries by removing only the necessary compartment lid rather than opening the entire battery box, maintaining ease of access while providing protection.
Solution Approach 2:
The armor lids are designed with dynamic characteristics - they can be quickly removed and reinstalled using simple fastening mechanisms. This dynamic design allows the armor to transition between protective and accessible states rapidly, maintaining operational efficiency despite the presence of armor protection.
4Object-affected harmful factors
If the battery box structure is modified to add protection, then protection against projectile impacts is improved, but the complexity of the device increases
Solution Approach 1:
The protective structure is segmented into standardized, pre-fabricated armor plate modules that can be independently manufactured and assembled. This modular approach simplifies the overall construction process and reduces assembly complexity compared to custom-integrated protection systems.
Solution Approach 2:
The armor plates are designed with universal mounting interfaces and standardized dimensions that can be applied across different battery box configurations. This universality reduces the number of unique parts needed and simplifies manufacturing and assembly procedures.

AI summary
The invention relates to a battery box (1) for a vehicle, the box comprising an inner space (1a) defined by walls (2a, 2b, 2e) and intended to receive at least one battery, the box comprising at least one removable cover (3) providing access to the inner space (1a) of the box. Said box is characterised in that it comprises at least two connecting lugs (11a, 11b) arranged in the inner space (1a) of the box and rigidly attached to the walls of the latter, at least one interface plate (5) which is attached by removable fastening means to the connecting lugs, and at least one first armour plate (4) which is removably attached to the interface plate (5) and which is housed in the inner space (1a) of the box between the cover (3) and the battery or batteries.
