Abstract: A traction battery assembly according to an exemplary aspect of the present disclosure includes, among other things, a thermal exchange plate having a plurality of coolant channels distributed within the thermal exchange plate according to a first pattern, and a thermal interface material disposed on a surface of the thermal exchange plate according to a second pattern. The first pattern mimics the second pattern.

Abstract: Protection and load distribution strategies are disclosed for electrified vehicle traction battery packs. Exemplary battery protection structures may include a corrugated portion and at least one flat sheet portion that are joined together. The battery protection structure may be integrated as part of an outer enclosure assembly of the traction battery pack or could embody a skid plate design that is a separate structure from the outer enclosure assembly. The battery protection structures may be configured for absorbing and transferring energy during vehicle loading events, thereby minimizing the transfer of loads inside the battery pack where relatively sensitive battery internal components are housed.

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: This disclosure details exemplary battery pack designs for use in electrified vehicles. Exemplary battery packs may include an enclosure assembly, one or more battery internal components (e.g., battery arrays, battery electronic components, or both) inside the enclosure assembly, and a structural brace outside of the enclosure assembly. The battery internal component may be mechanically coupled to the structural brace while also being mechanically decoupled from the enclosure assembly.

Abstract: A battery pack includes an enclosure assembly, a sensitive battery component housed inside the enclosure assembly, and a sacrificial battery component packaged outside of the enclosure assembly. The sacrificial battery component includes a pre-defined failure area configured to minimize the transfer of impact loads into the enclosure assembly. The sacrificial battery component may plastically deform and break at the pre-defined failure area in response to an impact loading event that exceeds a pre-defined load threshold of the pre-defined failure area.

Abstract: This disclosure relates to a battery for an electrified vehicle and a corresponding method. In particular, the battery and method accommodate for variable cell thickness. An example method of this disclosure includes inserting a separator between a first battery cell and a second battery cell. The separator has a thickness based on a thickness of the first battery cell and the second battery cell. This disclosure has a number of benefits. Among them, the method may be used to provide a battery array with a desired overall length despite differences in individual cell thickness. In turn, this leads to improved battery performance and lifespan.

Abstract: An exemplary support assembly includes, among other things, a hoop bracket coupling a battery pack to a vehicle body structure, and a tuned bracket within an open area of the hoop bracket. The tuned bracket is configured to control a collapse of the hoop bracket in response to a load above a threshold level to reduce a transfer of the load to the battery pack. An exemplary supporting method includes coupling a battery pack to a vehicle body structure using a hoop bracket disposed alongside the battery pack. The hoop bracket includes an open area that receives a tuned bracket. The tuned bracket is configured to control a deformation of the hoop bracket in response to a load above a threshold level to reduce a transfer of the load to the battery pack.
