Abstract: A battery pack thermal management system includes an outer conduit of a coolant conveying post, and an inner conduit of the coolant conveying post. The inner conduit disposed within the outer conduit. The coolant conveying post is configured to communicate coolant in a first direction through the outer conduit and outside of the inner conduit. The coolant conveying post is configured to communicate coolant in an opposite, second direction through the inner conduit.

Abstract: Bus bar assemblies are provided for electrically connecting battery cells within a battery array of a traction battery pack. An exemplary bus bar assembly may include a ladder frame and a bus bar plate that is mounted to the ladder frame. In some implementations, the bus bar plate is an arched bus bar plate. The bus bar plate may provide suitable welding surfaces for joining both battery cell tab terminals and sense leads to the bus bar plate. The battery cell tab terminals may be joined to the bus bar plate without positioning the bus bar plate perpendicular to the tab terminals and without bending the tab terminals.

Abstract: A traction battery assembly includes a plurality of battery cells arranged in a linear array, a substrate supporting the array, and an insulator assembly. The insulator assembly has outer compressible layers, at least one thermal insulation layer, and a metal layer. The metal layer includes a metal plate encapsulated in a dielectric material such that all surfaces of the metal plate are covered by the dielectric material, wherein the layers are secured to each other to form a unitary stack with the metal layer being disposed against the at least one thermal insulation layer and with the metal layer, the at least one thermal insulation layer is disposed between the outer layers, and the insulator assembly is disposed between an adjacent pair of the battery cells and is received on the substrate such that a portion of the dielectric material is between the substrate and the metal plate.

Abstract: A throttle body and an air control system that integrates the electronic engine control modules, sensors, actuators, and associated wiring on a throttle body is disclosed. In one version of the invention, there is provided a throttle body including a throttle body wall defining an airflow passage in the throttle body, a movable throttle plate that substantially conforms to the interior dimensions of the air flow passage, an engine control device (such as a sensor or an actuator) attached to the throttle body wall, and engine control electronics mounted to the throttle body wall in spaced apart relationship with the engine control device, the engine control electronics being electrically connected with the engine control device.

Abstract: There is disclosed herein an electronic control module assembly 30 for use in an internal combustion engine, wherein the engine includes an intake manifold 10 with N air inlet port(s) 14 and a throttle body 20 with N air outlet port(s) 24 where N=(1 or 2). One embodiment of the assembly 30 comprises: (a) a housing 32 having opposed upper and lower mounting surfaces 34/36 and an outer surface 38 about the housing, and N bore(s) 42 through the housing, wherein each bore has an upstream port 44 defined in the upper mounting surface 34 and a downstream port 54 defined in the lower mounting surface 36; (b) an electronic control module 60 for controlling one or more sub-systems of the engine; and (c) means 70 for attaching the electronic control module 60 to the outer surface 38 of the housing 32.
