BACKGROUND
[0002]
In the automotive industry, the advent of electric vehicles (EVs) has 5 significantly reshaped the landscape of transportation, emphasizing the importance of high-performance battery packs. Electrical cells such as lithium ion, both cylindrical and prismatic, are commonly employed due to their favorable energy density and power capabilities. However, as the demand for electric vehicles grows, the need for battery packs that are not only lightweight and compact but 10 also efficient in terms of cooling becomes increasingly apparent.
[0003]
Efficient cooling is essential to maintaining optimal performance and extending the lifespan of battery packs. Traditional cooling systems often struggle to meet the demands of automotive applications where space and weight considerations are critical. Additionally, as electric vehicles aim for faster charging 15 capabilities, the cooling system's ability to manage heat dissipation becomes even more crucial to prevent thermal runaway and ensure safe operation.
[0004]
One of the challenges in designing a cooling system for battery packs lies in effectively dissipating heat from the individual cells within the modules. These modules typically consist of multiple cells arranged in a specific configuration to 20
3
achieve the desired power output. However, conventional cooling methods may
not adequately address the heat generated during operation, especially when cells are stacked closely together.
[0005]
Therefore, there is an essential requirement for a solution that addresses the above-mentioned problems with a current power source units. 5
