Abstract: Exemplary battery pack designs for use in electrified vehicles may include an enclosure assembly that houses one or more battery internal components (e.g., battery arrays, battery electronic components, or both). A tear-away service panel may be positioned within a wall of the enclosure assembly. The service panel may be removed from the enclosure assembly to access one of the battery internal components requiring service and may be subsequently replaced with a replacement service panel. The replacement service panel may be part of a battery pack resealing kit.

Abstract: This disclosure details exemplary battery pack designs for use in electrified vehicles. An exemplary battery pack assembly process may include supporting one or more components, such as a heat exchanger plate, of the battery pack against deflection during the assembly process. Supporting the heat exchanger plate to keep the plate relatively flat during the battery pack assembly process improves the flow distribution of a thermal interface material (TIM), thereby achieving improved TIM coverage and improved heat transfer between battery cells and the heat exchanger plate of the battery pack.

Abstract: Electrified vehicles such as hybrid electric vehicles (HEV's), plug-in hybrid electric vehicles (PHEV's), battery electric vehicles (BEV's), or fuel cell vehicles differ from conventional motor vehicles in that they are powered by one or more electric machines (i.e., electric motors and/or generators) instead of or in addition to an internal combustion engine. High voltage current for powering these types of electric machines is typically supplied by a high voltage traction battery system having one or more battery cells that store energy.
