Abstract: An air duct system for a vehicle including at least one active air scoop configured to control air flow to the wheel wells of a vehicle. In some examples, the active air scoop can be positioned at the underbody of the vehicle. In some examples, the air duct system can include a first and second branch directing air to first and second areas of the wheel well. In some examples, the amount of air directed to the first and second branch are controlled by the active scoop and/or one or more valves in the air duct. In some examples, the active air scoop can be controlled based on one or more temperature measurements in the wheel well.

Abstract: Fluid cooled electric vehicle battery systems are disclosed. Systems can include an integrated coolant manifold and bus bar configured to carry coolant and electrical current along a common or coaxial path. An integrated coolant manifold and bus bar can include a conductive layer surrounding a coolant flow path and/or a conductor disposed within a coolant flow path. Integrated coolant manifold and bus bar structures may improve efficient use of battery space by reducing the number of battery components and by allowing reduced bus bar size due to fluid cooling of the bus bar.
