Refuse Body Battery Compartment Layout for Stable EV Collection Trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transition to electric refuse collection vehicles presents design challenges related to the integration and management of batteries, including weight distribution, accessibility, and compatibility with different vehicle chassis and cabs.
Innovation Solution
The implementation of a refuse collection vehicle design that incorporates battery compartments positioned within the interior volume of the refuse collecting body, aligned with the vehicle's longitudinal axis, and separated from the refuse collection area by a portion of the floor or panels, allowing for efficient weight distribution and easy battery replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If batteries are mounted on the chassis or under the cab, then weight distribution can be optimized, but the design is not compatible with different vehicle configurations and requires design alterations to the cab or chassis
Solution Approach 1:
The battery system is extracted from the traditional chassis-mounted or cab-mounted locations and relocated to the refuse collecting body. This separation allows the battery compartments to be integrated into the refuse body structure without requiring modifications to the chassis or cab designs, thereby achieving compatibility across different vehicle configurations while maintaining proper weight distribution
Solution Approach 2:
The refuse collecting body serves multiple functions: it not only collects and stores refuse but also houses the battery compartments that power the vehicle. This multi-functional integration allows the same structural space to serve both refuse management and energy storage purposes, eliminating the need for separate chassis modifications
2Stability of the object's composition
If batteries are positioned within the interior volume of the refuse collecting body, then weight distribution and vehicle stability are improved, but accessibility for battery replacement may be reduced
Solution Approach 1:
The battery system is divided into modular battery compartments that are positioned within the refuse collecting body. Each compartment is designed as a separate, accessible unit that can be independently opened and serviced. This segmentation allows batteries to be located in the interior volume for optimal weight distribution while maintaining ease of access through separate compartment openings
Solution Approach 2:
Panel structures serve as intermediary elements between the interior volume where batteries are positioned and the exterior access points. These panels can be opened or removed to provide access to the batteries while allowing the batteries to remain positioned within the interior volume for proper weight distribution and vehicle stability
3Reliability
If battery compartments are separated from the refuse collection area by floor panels, then battery protection and organization are improved, but the structural complexity of the floor increases
Solution Approach 1:
The floor structure is segmented into distinct sections: refuse collection areas and battery compartment areas. Panel structures create clear separations between these functional zones, providing protection and organization for the batteries while maintaining a relatively simple overall floor design through modular panel construction

AI summary
A refuse collection vehicle includes a chassis, a refuse collecting body supported by the chassis, a tailgate coupled to the refuse collecting body, and at least one battery compartment configured to receive one or more batteries. The at least one battery compartment is positioned within an interior volume of the refuse collecting body.
