Folded U-Shaped Battery Pack Layout for Electric Motorcycles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electric motorcycles face limited autonomy and stability issues due to the volume, weight, and placement constraints of traditional battery sets, which affect the center of gravity and increase accident risk.
Innovation Solution
A battery set for electric motorcycles is designed with a main block and side blocks forming a U-shape, allowing the rear wheel to be positioned between the side blocks, optimizing space and integrating an inverter and DC-DC converter, with protected connections and a cooling window, and featuring connecting plates with anchoring hooks for battery modules.

Engineering Contradiction Analysis
1Quantity of substance
If traditional square or rectangular battery sets are used, then the battery capacity is sufficient, but the volume and weight occupy too much space on the motorcycle
Solution Approach 1:
The battery set is divided into multiple battery modules arranged in specific configurations (series/parallel connections). These modules are organized into supporting structures with vertical and horizontal arrangements, segmenting the overall battery pack into manageable units that optimize space utilization while maintaining required capacity.
Solution Approach 2:
The patent utilizes three-dimensional space efficiently by arranging battery modules in both vertical and horizontal dimensions. The supporting structures create multiple levels and configurations (first and second battery modules in different orientations), transforming the traditional two-dimensional flat arrangement into a three-dimensional optimized layout that reduces the battery set's footprint on the motorcycle.
2Quantity of substance
If traditional battery sets are placed on motorcycles, then the battery capacity is adequate, but the center of gravity is affected and stability decreases
Solution Approach 1:
The battery modules are arranged with different orientations (vertical and horizontal) at specific locations within the motorcycle frame. The first battery modules are arranged vertically while second battery modules are arranged horizontally, creating localized density variations that optimize the center of gravity position and improve overall vehicle stability while maintaining required battery capacity.
