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 on the exterior of the case, and an attachment bracket connecting the sacrificial pocket to the vehicle body. The thin-walled section is designed to break away upon impact to prevent the transfer of the impact load to the battery case, ensuring the safety of the high voltage components.

Additionally, the assembly features non-sacrificial attachments that can withstand impact loads to prevent dislodging of the battery case from the vehicle body. The sacrificial pocket is integrally formed with the battery case and includes reinforcing side walls, an outer wall, and an upper wall, with an interior pocket cavity. The attachment bracket, typically an L-shaped stamped metal bracket, absorbs a portion of the impact load, enhancing the protective capabilities of the assembly. The design of the assembly aims to safeguard the high voltage battery modules within the cavity from impact forces, ensuring the overall safety and integrity of the vehicle.
