Abstract
Aspects of the subject disclosure relate to various features of a battery subassembly, such as a battery module. The battery subassembly may be implemented in an electric vehicle or in a building. The battery subassembly may include a potting dam as described herein.
Claims20
An apparatus, comprising:
- a potting dam, comprising:
- a peripheral portion configured to cover and extend substantially parallel to a peripheral portion of an electrical structure of a battery subassembly;
- a wall that extends from the peripheral portion;
- and
- a central opening defined by the wall, wherein the wall is configured to block a potting material provided via the central opening, and the peripheral portion surrounds the wall and the central opening, wherein the peripheral portion of the potting dam that covers and extends substantially parallel to the peripheral portion of the electrical structure is configured to be spaced apart by a gap from the peripheral portion of the electrical structure, and to allow a portion of the potting material to fill a portion of the gap.

A battery subassembly comprising:
- a potting dam, the potting dam comprising:
- a peripheral portion configured to cover and extend substantially parallel to a peripheral portion of an electrical structure of the battery subassembly;
- a wall that extends from the peripheral portion;
- an opening defined by the wall, wherein the wall separates the opening from the peripheral portion and is configured to dam a potting material provided onto the electrical structure via the opening, wherein the peripheral portion of the potting dam that covers and extends substantially parallel to the peripheral portion of the electrical structure is configured to be spaced apart by a gap from the peripheral portion of the electrical structure, and to allow a portion of the potting material to fill a portion of the gap;
- an overhang extending from an edge of the peripheral portion;
- and
- a lip extending substantially horizontally from the wall, wherein the overhang and the lip are further configured to dam the potting material.
4 more elements
A method, comprising:
- attaching, to a battery subassembly having an electrical structure with a surface, a peripheral portion of a potting dam having a wall extending from the peripheral portion such that the peripheral portion of the potting dam covers and extends over and is parallel to a peripheral portion of the surface of the electrical structure, the wall defining a central opening of the potting dam;
- providing a potting material onto the surface of the electrical structure of the battery subassembly via the central opening in the potting dam;
- and
- restricting, with the wall and the peripheral portion of the potting dam, the potting material from flowing over an edge of the electrical structure of the battery subassembly, wherein the peripheral portion surrounds the wall and the central opening,
- wherein restricting, with the wall and the peripheral portion of the potting dam, the potting material from flowing over the edge of the battery subassembly comprises allowing a portion of the potting material to flow under the peripheral portion of the potting dam between a surface of the peripheral portion of the potting dam and a surface of an electrical structure of the battery subassembly.
