Publication number: 20230074724Abstract: A cold plate for a battery may comprise channels that extend from a first end of the plate to a second end of the plate or from a first side of the plate to a second side of the plate, the channels are located in parallel with each other and between the top surface and the bottom surface. The channels may be separated from each other by walls. The plate may be milled to form a first manifold on each end. The plate may also be milled to form notches in the surface(s) over the manifold. A port for the inlet and a port for the outlet of a working fluid may be inserted into the notches. The plate may have end caps, and the end caps and the ports may be welded or brazed to form a sealed enclosure. In various embodiment, the plate is an extruded plate, a cast plate, or a stamped/formed plate.Type: ApplicationFiled: November 15, 2022Publication date: March 9, 2023Applicant: Romeo Systems, Inc.Inventors: W.

Patent number: 10144466Abstract: A method for manufacturing a vehicle frame is disclosed. An upper body of the vehicle frame is formed, the upper body configured to be joined with an underbody of the vehicle frame at a first component of the upper body. The underbody of the vehicle frame is formed, the underbody configured to be joined with the upper body at a first component of the underbody. After forming the upper body and the underbody, a point on the upper body is aligned with a desired position for the point, independent of an alignment between the first component of the upper body and the first component of the underbody. After aligning the point on the upper body with the desired position for the point, the first component of the upper body is joined to the first component of the underbody.Type: GrantFiled: June 22, 2016Date of Patent: December 4, 2018Assignee: FARADAY&FUTURE INC.Inventors: Umran Ashraf, Felix Scheile, John Michael Colt
