Removable Trailer Battery Containers for Adaptive Electric Assist
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Heavy goods vehicles face challenges in fuel consumption and pollution due to the constraints of electrical energy storage, particularly in trailers, where existing solutions either limit adaptability, increase weight, or complicate battery management.
Innovation Solution
A land vehicle or heavy goods trailer with a goods storage compartment containing removable electrical energy containers, connected to an axle motor system via an electric bus, allowing for easy addition or removal of containers and adaptive energy management, including geolocation and energy recovery systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery is placed in the trailer chassis, then the electrification system can be implemented, but the battery becomes difficult to remove or replace and requires specific moving means
Solution Approach 1:
The battery is extracted from the trailer chassis and placed in the goods storage compartment instead. This allows the battery to be easily removed along with goods using standard handling equipment, eliminating the need for specific moving means while maintaining electrification functionality.
Solution Approach 2:
The goods storage compartment serves dual purposes: it stores goods and accommodates the battery. This multi-functional use of space allows the battery to be handled as part of regular cargo operations, improving ease of removal and replacement without requiring dedicated battery handling systems.
2Reliability
If the battery is placed in the trailer chassis, then the electrification system can operate, but the size of the battery is limited and therefore the amount of electrical energy is reduced
Solution Approach 1:
The battery placement moves from the constrained horizontal space of the trailer chassis to the vertical three-dimensional space of the goods storage compartment. This dimensional change allows for larger battery configurations that can store more electrical energy while still fitting within the overall trailer structure.
3Duration of action of moving object
If additional batteries are added to increase autonomy, then the energy capacity increases, but the weight of the vehicle increases
Solution Approach 1:
The battery configuration becomes dynamic and adaptable - batteries can be added or removed from the goods storage compartment based on specific mission requirements. This allows optimization between autonomy and weight for different operational scenarios, rather than being fixed with always carrying maximum battery capacity.
4Stability of the object's composition
If the battery is integrated into the trailer structure, then the system is stable, but the electrification cannot be adapted according to needs and handling becomes complex
Solution Approach 1:
The electrification system is segmented into modular battery units that can be independently added or removed from the goods storage compartment. This segmentation maintains system stability when batteries are present while enabling easy adaptation of the electrification configuration based on specific operational needs.
