Electric Work Vehicle Battery Layout for Front Balance Weight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric work vehicles face challenges in balancing weight distribution due to the placement of batteries, which affects the center of gravity and stability, especially when performing tasks that increase load at the front portion, such as towing.
Innovation Solution
Positioning the battery at the front portion of the traveling body with the travel motor below it, and using a cable that extends from the rear to supply power, allowing the battery's load to contribute to balance weight and protecting components with a cover to prevent damage from debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the battery is positioned at the front portion of the traveling body, then the load of the battery is applied to the front portion which helps achieve balance when towing, but the cable must extend from the rear portion which increases cable length and complexity
Solution Approach 1:
The cable is routed through the vertical dimension by passing it through the battery housing from the rear side, allowing the battery to be positioned at the front for balance while the cable connects from the rear without requiring excessive horizontal length or complex external routing
2Stability of the object's composition
If the motor is positioned below the battery, then the center of gravity is lowered which improves stability, but the available space for component arrangement is reduced
Solution Approach 1:
The motor is positioned in the vertical dimension below the battery rather than in the horizontal plane, allowing both components to be arranged in a compact configuration that lowers the center of gravity while maintaining adequate space for other components through three-dimensional space utilization
3Reliability
If a cover is added to protect the battery and cable, then the components are protected from damage, but the device complexity and manufacturing cost increase
Solution Approach 1:
The cover serves multiple functions simultaneously: it protects the battery and cable from external damage, provides structural support for the battery mounting, and facilitates the cable routing through its design with integrated cable passage, thereby reducing the need for separate protective structures
Solution Approach 2:
The protective cover is integrated with the battery housing structure, combining the protection function with the mounting and cable routing functions into a single unified component rather than using separate elements for each function
