Abstract:
1. A battery cell assembly, comprising: a first frame member having a first rectangular ring-shaped body and a first plurality of tabs extending away from a first peripheral edge of the first rectangular ring-shaped body, each tab of the first plurality of tabs having a first tab portion, the first tab portion extending in a first direction from the first rectangular ring-shaped body and being substantially perpendicular to the first rectangular ring-shaped body, each tab of the first plurality of tabs further having a first coupling feature at a distal end of the first tab portion that extends substantially perpendicular to the first tab portion and toward an inner open region defined by the first rectangular ring-shaped body; the first peripheral edge further having a first plurality of slots extending into the first peripheral edge, each slot of the first plurality of slots being disposed directly adjacent to a respective tab of the first plurality of tabs; a second frame member being directly coupled to the first frame member, the second frame member having a second rectangular ring-shaped body and a second plurality of tabs extending away from a second peripheral edge of the second rectangular ring-shaped body, each tab of the second plurality of tabs having a second tab portion, the second tab portion extending in the first direction from the second rectangular ring-shaped body and being substantially perpendicular to the second rectangular ring-shaped body, each tab of the second plurality of tabs further having a second coupling feature at a distal end of the second tab portion that extends substantially perpendicular to the second tab portion and toward an inner open region defined by the second rectangular ring-shaped body; the second peripheral edge further having a second plurality of slots extending into a second peripheral edge, each slot of the second plurality of slots being disposed directly adjacent to a respective tab of the second plurality of tabs; a first slot of the second plurality of slots having a depth in a second direction from the second peripheral edge toward an inner open region of the second rectangular ring-shaped body that is greater than a length of an engaging surface of a first coupling feature of a first tab of the first plurality of tabs such that an open space is defined in the second direction between an end of the engaging surface of the first coupling feature of the first tab of the first plurality of tabs and the second rectangular ring-shared body when the first coupling feature of the first tab of the first plurality of tabs is disposed in the first slot of the second plurality of slots and is coupled to the second rectangular ring-shaped body; the engaging surface of the first coupling feature of the first tab of the first plurality of tabs directly contacting the second rectangular ring-shaped body; and a battery cell being disposed between the first and second frame members when the first and second frame members are coupled together.
