Abstract
Battery pack designs for use in electrified vehicles may include a polymer-based enclosure having features for sealing external joints, retaining components inside the battery pack, securing electrical and coolant lines to the polymer-based enclosure, etc. The proposed designs reduce the number of overall parts in assembly, such as fasteners and brackets, and simplify the overall battery pack manufacturing and assembly processes.
Claims20
A battery pack, comprising:
- an enclosure assembly including a tray, a mid-tray, and a cover,
- wherein the mid-tray is secured to the tray at a tongue and groove connection;
- and
- at least one of a tape seal or a liquid seal applied at an external seam associated with the tongue and groove connection.
A battery pack, comprising:
- an electrical subassembly;
- a foam shell disposed around the electrical subassembly to establish a foamed electrical subassembly;
- and
- a battery array connected to the foamed electrical subassembly.
A battery pack, comprising:
- a polymer-based enclosure;
- a connector secured to the polymer-based enclosure,
- wherein the connector includes a connector body and a weld flange that circumscribes the connector body;
- and
- an electrical or coolant line secured to the connector body.
