Vehicle Electric Component Arrangement Heat Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric component arrangements in vehicles are vulnerable to heat influences from the engine and have lengthy harnesses that lead to inefficiencies in electricity supply, particularly for electricity-storage devices, converters, and batteries.
Innovation Solution
The electric component arrangement structure positions the generator at the front of the engine, with the electricity-storage device and converter on the opposite side of the vehicle width, allowing for straighter harnesses and minimizing heat exposure by placing the electricity-storage device outside the engine room and in front of a front wheel for better air cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If electric components (electricity-storage device, convertor, battery) are installed in the engine room, then the length of harnesses can be shortened, but the components are exposed to improper heat influence from the engine
Solution Approach 1:
The electricity-storage device is extracted from the conventional engine room location and placed in a new location on the vehicle front side, outside the engine room. This separation removes the harmful heat influence from the engine while the convertor acts as an intermediary to maintain electrical connectivity with shortened harnesses
2Object-affected harmful factors
If the generator is positioned on one side of the vehicle and electric components on the other side, then heat influence is reduced, but harness length increases
Solution Approach 1:
The electrical connection is arranged in three-dimensional space by routing the harness through the vehicle width direction and utilizing vertical space, allowing the generator and electricity-storage device to be positioned on opposite sides while maintaining a compact harness path that does not simply follow a linear horizontal route
3Object-affected harmful factors
If electric components are placed away from the engine to reduce heat exposure, then heat resistance is improved, but the complexity of the arrangement structure increases
Solution Approach 1:
The convertor is designed to serve multiple functions: it converts electricity from the generator to the battery, acts as an electrical connection point between components on opposite sides of the vehicle, and serves as a mounting structure that integrates the harness routing system, thereby reducing overall arrangement complexity

AI summary
A generator is provided at a front portion of an engine provided between a pair of front side frames at an offset position on one side, in a vehicle width direction, of a vehicle, and an electricity-storage device, a convertor, and a battery are provided on the other side, in the vehicle width side, of the vehicle. Accordingly, the electricity-storage device, the convertor, and the battery can be restrained from receiving any improper heat influence from the engine, and the length of harnesses coupling the generator, the electricity-storage device, the convertor, and the battery can be shortened as much as possible.
