Abstract: 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.

Abstract: Connection and control concepts for battery packs in a high voltage battery assembly are provided. Parallel, modular configurations permit improved safety, voltage balancing, and redundancy, improving operation and reliability of an associated high voltage electrical vehicle such as a heavy-duty truck.

Abstract: Systems and methods provide for battery conditioning for high voltage (HV) electrical vehicles. Battery temperatures are monitored, and responsive to one or more battery temperatures falling within designated ranges, one or more battery temperatures may be increased via heating in order to provide for more uniform battery performance and conditioning.

Abstract: A webbing device for a vehicle underbody can comprise a plurality of rows of ribs and members that extend between the ribs to provide rigidity and force load distribution. The webbing device can comprise channels to receive a variety of structural components of the underbody and can accommodate underbodies of various sizes without altering its rigidity and force load distribution.

Abstract: 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.
