Abstract: A vehicle power module assembly including first and second power modules is provided. The first power module may include a first lock feature extending from a lower portion of a first minor side at a first central axis. The second power module may include a second lock feature at an upper portion of a second minor side at a second central axis. The lock features may be sized for interlock with one another to secure the power modules to one another. The first lock feature may be a loop element defining a through-hole and the second lock feature may be a wedge. The through-hole may be sized for the wedge to extend therein and to interlock the first power module and the second power module to one another. The first lock feature may be a flexible hook element and the second lock feature may be a slot.

Abstract: An electric vehicle power supply includes a housing, a power supply, and a plurality of fasteners. The housing defines an internal cavity and has inwardly protruding tabs that extend into the cavity. The power assembly has a front cover and an end cover. The power assembly also has an array of electrical switching units arranged horizontally between the front and end covers. The front and end covers have outwardly protruding tabs. Each of the plurality of fasteners extend vertically, engage one inwardly protruding tab, and engage one outwardly protruding tab to secure the power assembly to the housing.

Abstract: According to one embodiment, a power-module assembly includes a power-module stack having coolant chambers interleaved with power modules and supply and return manifold channels extending axially along the stack. An endcap has a major side defining recessed inlet and outlet manifold cavities aligned with the channels and inlet and outlet ports disposed on one or more minor sides that are perpendicular to the major side.

Abstract: A vehicle power supply includes a housing, a backing plate, a power assembly, and a clamp. The housing has a bottom wall and a side wall. The backing plate extends from the bottom wall. The power assembly has an array of electrical switching units that extend from the side wall to the backing plate. The clamp extends from the backing plate and is configured to engage a backside of the array such that a frontside of the array is forced into engagement with the side wall.
