Working Vehicle Battery Layout for External Side-Mounted Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of securing installation space for additional equipment, such as a fuel cell module, in a working vehicle with a battery located inside the hood is addressed by positioning the battery assembly outward of the vehicle body in the width direction.
Innovation Solution
The battery assembly is positioned between the front and rear wheels, overlapping the front pillar and fender, with a lower portion below the cabin and a front portion extending upward along the front pillar, allowing for efficient use of space without increasing the vehicle's width.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the battery is located inside the hood, then the battery is protected and integrated into the vehicle body, but it becomes difficult to secure wide installation space for other equipment inside the hood
Solution Approach 1:
The patent applies dimensionality change by moving the battery assembly from the horizontal plane (inside the hood) to the vertical dimension (outward of the vehicle body in the width direction, between the front and rear wheels). This allows the battery to occupy space that does not interfere with the hood's internal volume, thereby resolving the space conflict while maintaining vehicle integration.
2Area of stationary object
If the battery assembly is positioned outward of the vehicle body between the front and rear wheels, then installation space for other equipment is secured, but the vehicle's width increases
Solution Approach 1:
The patent applies the nesting principle by positioning the battery assembly within the existing wheel track envelope. The battery is nested between the front and rear wheels in the width direction, utilizing the space already defined by the vehicle's traveling device. This allows the battery to be installed outward of the main vehicle body without significantly increasing the overall vehicle width, as it fits within the wheelbase footprint.
3Area of stationary object
If the battery assembly overlaps the front pillar and fender, then space utilization is optimized, but operator access and visibility may be obstructed
Solution Approach 1:
The patent applies local quality by strategically positioning the battery assembly to overlap specific regions (front pillar and fender areas) where the mass distribution benefits vehicle stability without creating operational obstructions. The battery's lower portion is placed below the cabin level, ensuring that the operator's line of sight and physical access to controls remain unobstructed, while still achieving optimal space utilization in the lateral dimension.

AI summary
A working vehicle includes a vehicle body, an electric motor in or on the vehicle body, and a battery assembly including a battery to store electric power to be supplied to the electric motor. The battery assembly is located outward of the vehicle body in a width direction of the vehicle body. It is preferable that the battery assembly be located between a front wheel and a rear wheel of the vehicle in a side view of the vehicle body.
