Abstract
A traction battery pack assembly includes first and second thermal barriers each having a divider section and a covering section, and one or more battery cells sandwiched between the divider section of the first thermal barrier and the divider section of the second thermal barrier along a cell stack axis. The covering section of the first thermal barrier extends axially over at least a portion of the one or more battery cells and interfaces with the covering section of the second thermal barrier through a tongue-and-groove interface.

A traction battery pack assembly, comprising:
- first and second thermal barriers each having a divider section and a covering section;
- and
- one or more battery cells sandwiched between the divider section of the first thermal barrier and the divider section of the second thermal barrier along a cell stack axis, the covering section of the first thermal barrier extending axially over at least a portion of the one or more battery cells and interfacing with the covering section of the second thermal barrier through a tongue-and-groove interface.
A traction battery pack assembly, comprising:
- first and second thermal barriers each having a T-shaped cross-section with a stem section and a T-top section;
- and
- one or more battery cells sandwiched between the stem section of the first thermal battery and the stem section of the second thermal barrier along a cell stack axis, the T-top section of the first thermal barrier extending axially over at least a portion of the one or more battery cells in a first axial direction, the T-top section of the second thermal barrier extending axially over at least a portion of the one or more battery cells in a second axial direction to interlock with the T-top section of the first thermal barrier.
A traction battery pack assembly, comprising:
- first and second thermal barriers each having a divider section and a covering section, the divider section of the first thermal barrier and the divider section of the second thermal barrier configured to sandwich one or more battery cells along a cell stack axis, the covering section of the first thermal barrier configured to extend axially over at least a portion of the one or more battery cells to interface with the covering section of the second thermal barrier through a tongue-and-groove interface.
