Revolutionary Side Cooling Technique
The side cooling battery pack in Tesla vehicles employs an arc-shaped water-cooled plate that seamlessly adheres to the side of each cylindrical battery cell. This optimized design rapidly draws heat from the battery cell, efficiently transferring it to the coolant. Benefiting from the extensive surface area of cylindrical cells, the arc-shaped water-cooled plates enhance the interface between the battery cell and coolant, improving thermal management.
The side cooling method enhances the contact area between coolant and the battery pack pressure relief valve by 50% compared to traditional cooling approaches, thereby maximizing heat dissipation efficiency.
High-Strength Body Structure
Tesla integrates a robust body framework using herringbone ultra-high strength steel in key sections such as the threshold beam and floor crossbeam. The synergy between herringbone extruded aluminum and steel ensures robust body integrity and reduced weight. In the event of impact, the threshold beam, aided by the herringbone design, effectively protects the passenger compartment and battery pack pressure relief valve by absorbing significant kinetic energy while collapsing.
The vehicle floor hosts three ultra-high strength steel beams with tensile strengths reaching 1700MPa. These beams bolster the threshold beam to guard the passenger area and battery pack pressure relief valve from further compression in case of structural deformation.
