Abstract: A battery module includes: positive and negative terminals disposed on an exterior of a housing of the battery module; groups of two or more cylindrical battery cells, each of the battery cells of each group having positive and negative terminals; and electrically conductive busbars that electrically connect the groups, that electrically connect positive terminals of the battery cells of a first one of the groups with the positive terminal of the battery module, and that electrically connect negative terminals of the battery cells of a second one of the groups with the negative terminal of the battery module; and a cooling plate including: first and second second planar plates; and a coolant channel plate that is sandwiched between the first and second planar plates that includes: an inlet; an outlet; and a coolant channel that extends in at least two different directions.

Abstract: An underbody assembly for a vehicle includes a plurality of polymer-fiber composite components. The polymer-fiber composite components include a base and a first reinforcement. The base includes a first side and a second side. The base is configured to extend in a longitudinal direction between a front of the vehicle and a rear of the vehicle. The first reinforcement is coupled to the base. The first reinforcement includes a first elongated ridge and a first elongated trough. The first elongated trough is disposed adjacent to the first elongated ridge. The first elongated ridge and the first elongated trough each extend transversely between the first side of the base and the second side of the base. In various aspects, the underbody assembly consists essentially of the polymer-fiber composite components.
