EV Battery and Radiator Layout for Better Traveling-Air Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The layout of functional parts in an electric vehicle with a battery extending between a down frame and a pivot frame is difficult due to the battery's large capacity, and existing designs do not effectively utilize traveling air for radiator cooling.
Innovation Solution
The radiator is positioned below the battery, with the rear side of the battery's bottom surface lower than the front side, allowing easy air intake and improved cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery is disposed extending between the down frame and the pivot frame, then the battery capacity can be increased for longer cruising distance, but the layout freedom of functional parts is reduced
Solution Approach 1:
The battery is disposed at an inclination in the vehicle width direction rather than horizontally, utilizing three-dimensional space efficiently. This dimensional change allows the battery to extend between the down frame and pivot frame while creating available space below the battery for radiator placement, thus resolving the layout constraint issue
2Adaptability or versatility
If the radiator is disposed below the seat, then the layout freedom is ensured, but the cooling property is reduced due to limited air intake
Solution Approach 1:
The radiator is positioned below the battery in the vehicle width direction, utilizing the three-dimensional space created by the inclined battery arrangement. This spatial reconfiguration allows the radiator to access traveling air from the front of the vehicle while maintaining a compact layout, thereby improving cooling efficiency without compromising layout freedom

AI summary
An electric vehicle comprises: a vehicle body frame that includes a down frame and a pivot frame, the down frame extending downward from a head pipe, the pivot frame pivotally supporting a rear wheel; a battery that is disposed in an extending manner between the down frame and the pivot frame; and a radiator that cools an electric vehicle functional part. In the electric vehicle, the battery is disposed such that a rear side of a battery bottom surface is lower than a front side of the battery bottom surface, and the radiator is disposed below the battery bottom surface.
