Solution Overview
Problem
Conventional battery packs face challenges in effectively cooling a larger number of battery modules with a simpler structure, as existing designs often require complex cooling mechanisms to manage heat dissipation efficiently.
Innovation Solution
The battery pack design incorporates a housing with multiple outer walls and elastic members to thermally connect battery modules to these walls, allowing for effective heat transfer and dissipation, while also being dust-proof and drip-proof to protect the modules from environmental contaminants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional cooling mechanisms are used to cool battery modules, then heat dissipation is achieved, but the structure becomes complex
Solution Approach 1:
The housing serves dual functions as both structural enclosure and heat dissipation component. The housing is thermally connected to the battery modules and includes heat radiating surfaces, merging the protective enclosure function with the cooling function into a single integrated structure, thereby achieving heat dissipation without adding separate complex cooling mechanisms.
Solution Approach 2:
The housing is designed as a multi-functional component that simultaneously provides mechanical protection, structural support, and thermal management. By making the housing thermally conductive and incorporating heat radiating surfaces, it performs multiple functions including containment, support, and active heat dissipation, eliminating the need for dedicated cooling structures.
2Quantity of substance
If more battery modules are installed in the housing, then capacity increases, but heat dissipation becomes more difficult
Solution Approach 1:
The housing is thermally connected to multiple battery modules simultaneously, serving as a common heat sink for all modules. This integration allows heat from numerous modules to be dissipated through the housing's external surfaces, enabling high capacity installation while maintaining effective thermal management across all battery units.
