Patent number: 11942658Abstract: A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.Type: GrantFiled: June 28, 2021Date of Patent: March 26, 2024Assignee: Rivian IP Holdings, LLCInventors: Ehsan Baseri, Kyle Butterfield, Luke Rayment Morrow, Akshay Kishor Murkute, Jonathan Verghese

Patent number: 11876200Abstract: An electric vehicle battery pack with a thermal shield that protects internal components from, for example, battery ventilation, and in particular allows battery pack electrical components to be placed above venting ends of batteries. The thermal shield is positioned above the venting ends of one or more batteries, and various battery pack electrical components may be placed above the thermal shield. Gases and particulate matter from battery venting are thus intercepted and deflected by the thermal shield, instead of damaging battery pack electrical components. In this manner, various battery pack electrical components may be placed above battery venting ends without risk of damage. This allows for a more compact and versatile arrangement of battery pack components.Type: GrantFiled: July 13, 2021Date of Patent: January 16, 2024Assignee: Rivian IP Holdings, LLCInventors: Ehsan Baseri, Kyle Butterfield, Vignesh Sekar
