Electric Tractor Battery Module Layout for Chassis Weight Balance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to optimally arrange battery modules in a tractor's chassis for battery-powered electric tractors, ensuring good weight distribution, low center of gravity, and efficient space utilization while accommodating different designs and axle configurations, similar to those with internal combustion engines, using modular systems with minimal parts.
Innovation Solution
The solution involves strategically placing battery modules behind and in front of the rear axle, with one module lying on edge and the other extending across the axle position, allowing for compact installation and efficient use of space, and utilizing a modular system with various chassis and motor configurations to accommodate different tractor designs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If battery modules are accommodated in the chassis of an electric tractor, then the tractor can operate with battery-powered electric drive, but the batteries are very voluminous and heavy, making it difficult to fit them in the available space
Solution Approach 1:
The patent applies dimensionality change by arranging battery modules not only longitudinally but also laterally across the chassis width. Battery modules are positioned on both sides of the longitudinal centerline, utilizing the transverse dimension to maximize space utilization. This allows the tractor to accommodate sufficient battery capacity while maintaining a compact overall footprint.
Solution Approach 2:
The battery system is segmented into multiple individual battery modules rather than using a single large battery unit. This segmentation allows flexible arrangement of modules in the available chassis space, enabling optimal weight distribution and center of gravity positioning while accommodating the total required energy capacity.
2Adaptability or versatility
If multiple different sized chassis are offered to accommodate different numbers of battery modules, then various tractor designs can be achieved, but the device complexity and number of parts increase
Solution Approach 1:
The patent establishes a universal chassis design that can accommodate various numbers and configurations of battery modules through standardized mounting positions. The same basic chassis structure serves multiple functions by supporting different battery module arrangements, eliminating the need for multiple specialized chassis types while maintaining design flexibility.
Solution Approach 2:
The battery module arrangement is made dynamic and adjustable rather than fixed. Modules can be positioned at different locations and orientations within the chassis, allowing the same chassis to adapt to different energy capacity requirements and design specifications without requiring structural modifications.

AI summary
In order to be able to accommodate the required number of battery modules (5)—specified in terms of their external dimensions—and in particular the number required by the customer, with good weight distribution, in the chassis gradations of diesel tractors, in particular of long cabs, when switching to a battery electric drive, different arrangements of the battery modules (5) at the front and in particular also at the rear in the chassis (2) are proposed according to the invention.
