Solution Overview
Problem
Conventional battery modules for electric vehicles and hybrid vehicles face a challenge in cooling efficiency due to increased size requirements for heat dissipation, which compromises the compactness of the battery pack.
Innovation Solution
A battery module with a compact cooling structure that includes a front and rear plate, side plates with cooling channels, and a heat-dissipating member, allowing for efficient heat absorption and dissipation without increasing the overall size, utilizing a heat transfer material and adjustable coupling members for secure assembly and pressure application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a channel gap is formed between battery cells and a coolant circulates through the channel gap for cooling, then cooling performance is improved, but the overall size of the battery module is increased
Solution Approach 1:
The cooling channel is integrated into the side plates that are already part of the battery module structure, merging the cooling function with the structural support function. This eliminates the need for separate cooling channels between battery cells, achieving compact cooling without increasing overall module size
Solution Approach 2:
The side plates serve multiple functions: they provide structural support for the battery cells and simultaneously contain the cooling channels. This multi-functionality allows the cooling system to be embedded within existing structural components, avoiding additional space requirements

Implementation Method 1
a heat-dissipating member arranged under the battery pack and absorbing heat generated by the battery pack
Implementation Method 2
side plates arranged at lateral ends of the front plate and the rear plate, arranged to be in contact with respective lateral ends of the heat-dissipating member, and having a cooling channel through which a coolant circulates to thus cool the battery pack
