Tab-direct cooling battery module

Tab-direct cooling module that extends plate-fin structures to wrap and cool cell tabs

This technology addresses heat generation in the tab areas of pouch-type battery cells by extending existing parallel plate-fin cooling structures to wrap and compress the tab heat dissipation section, effectively dissipating heat from the tabs to the outside through compression pads and internal fins.

While conventional parallel plate-fin methods are effective for cooling the sides of battery cells, they struggle to efficiently dissipate heat from the high-temperature tab areas, leading to uneven temperature distribution and reduced battery performance and lifespan.

By adding tab heat dissipation plates (first and second tab heat sinks) that wrap around both sides of the tabs and extending the existing internal fins and compression pads to enclose these heat sinks, this technology can be applied to improve the stability and longevity of battery thermal management and safety systems.

Key Features:

• A plurality of battery cells, each having tabs protruding outward and arranged such that the tabs are aligned in a first direction
• Cooling fins disposed between each pair of adjacent battery cells to face the surface of the battery cells
• A configuration that extends the plate-fin cooling structure to wrap and compress the battery cell's tab heat dissipation section
• A battery module that manages cell temperature by directly cooling the heat generated at the tab area using plate fins
