A high voltage battery case assembly for a vehicle has been granted a patent (Publication Number: US11919404B2). The assembly includes a battery case with walls defining a cavity for high voltage battery modules, a sacrificial pocket with a thin-walled section designed to break away upon impact, and an attachment bracket connecting the sacrificial pocket to the vehicle body. This design aims to prevent the transfer of impact loads to the battery case, ensuring the safety and integrity of the high voltage battery assembly in the event of a collision.

Additionally, the assembly features non-sacrificial attachments integrated into the battery case to withstand impact loads and prevent dislodging from the vehicle body. The sacrificial pocket, with reinforcing side walls and an interior pocket cavity, is strategically designed to absorb impact energy and protect the battery case assembly. The attachment bracket, made of stamped metal, is configured to absorb impact forces, further enhancing the safety features of the assembly. Overall, this patented high voltage battery case assembly offers a robust and innovative solution for protecting high voltage battery modules in vehicles, ensuring safety and reliability in various driving conditions.
