Vertical Battery Stacking for Heat Dissipation in Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle battery systems comprising high-capacity and high-power batteries lack optimal arrangement, leading to reduced salability and performance due to differing characteristics, which affects heat dissipation, usage frequency, and durability, ultimately impacting running distance and fuel economy.
Innovation Solution
The vehicle incorporates a high-capacity battery pack above a high-power battery pack, with the high-capacity batteries placed to facilitate heat dissipation and increased rigidity, allowing for efficient electric power supply and extended running distance, while the high-power batteries handle momentary power demands and noise reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the high-capacity battery is placed below the high-power battery, then the vehicle structure is simplified, but heat dissipation from the high-capacity battery is impaired and battery characteristics deteriorate
Solution Approach 1:
The patent transitions from horizontal battery arrangement to vertical stacking, placing the high-capacity battery above the high-power battery. This dimensional change enables superior heat dissipation for the high-capacity battery while maintaining compact vehicle structure and simplified installation procedures
2Quantity of substance
If the high-capacity battery is made larger to increase capacity, then running distance is extended, but luggage space is reduced
Solution Approach 1:
The patent utilizes the vertical dimension by stacking the high-capacity battery above the high-power battery within the luggage compartment. This vertical arrangement maximizes battery capacity while preserving horizontal luggage space for passenger use
3Adaptability or versatility
If the high-capacity battery is accessed frequently for replacement, then adaptability is improved, but ease of operation deteriorates due to difficult access
Solution Approach 1:
The patent positions the high-capacity battery in the upper portion of the vertical arrangement, making it easily accessible from above for frequent replacement operations, while the high-power battery remains in the lower position

AI summary
[PROBLEM] To place a high-power assembled battery and a high-capacity assembled battery at optimal positions in a vehicle. [SOLVING MEANS] A vehicle includes a motor serving as a driving source for running the vehicle, and a high-power assembled battery and a high-capacity assembled battery each capable of supplying an electric power to the motor and placed in a luggage space. The high-power assembled battery is capable of charge and discharge with a current relatively larger than that in the high-capacity assembled battery. The high-capacity assembled battery has an energy capacity relatively larger than that of the high-power assembled battery and has a higher dependence of battery characteristic on temperature than that of the high-power assembled battery. The high-capacity assembled battery is placed over the high-power assembled battery in the vehicle.
