Battery pack retention assembly and retention method

#This disclosure is directed toward retaining areas of a battery pack and, more particularly, to utilizing an extrusion to secure portions of a battery array within a battery pack.

#Generally, electrified vehicles differ from conventional motor vehicles because electrified vehicles are selectively driven using one or more battery-powered electric machines. Conventional motor vehicles, by contrast, rely exclusively on an internal combustion engine to drive the vehicle. Electrified vehicles may use electric machines instead of, or in addition to, the internal combustion engine.

#Example electrified vehicles include hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), fuel cell vehicles, and battery electric vehicles (BEVs). A powertrain of an electrified vehicle is typically equipped with a battery pack having battery cells that store electric power for powering the electric machines.

#The various features and advantages of the disclosed examples will become apparent to those skilled in the art from the detailed description. The figures that accompany the detailed description can be briefly described as follows:

#FIG. 1 is a schematic view of an example powertrain of an electrified vehicle.

#FIG. 2 is a schematic perspective view of a battery array within powertrain of FIG. 1.

#This disclosure relates generally to an extrusion that secure a battery array within a battery pack. The extrusion provides effective retention within a relatively tight packaging space.

#FIG. 1 schematically illustrates a powertrain 10 for a hybrid electric vehicle (HEV). The powertrain 10 includes a battery pack 14, a motor 18, a generator 20, and an internal combustion engine 22.

#The motor 18 and generator 20 are types of electric machines. The motor 18 and generator 20 may be separate or may have the form of a combined motor-generator.
