Current collector assembly with an elongated fuse

A battery subassembly, comprising:

• a current collector assembly electrically coupled with one or more battery cells, the current collector assembly comprising an electrically conductive layer that comprises:
• a first tab electrically coupled with a first battery cell of the one or more battery cells;
• a first fuse connected to the first tab, the first fuse comprising a first portion extending along a first direction and having a first width, the first fuse further comprising a second portion extending along a second direction different from the first direction and having a second width greater than the first width;
• a second tab electrically coupled with a second battery cell of the one or more battery cells;
• a second fuse connected to the second tab;
• an interconnect, wherein the first portion of the fuse is connected to the interconnect and the second fuse is connected to the interconnect;
• a thermal collector that extends from the interconnect and is configured to receive thermal energy generated in the electrically conductive layer, wherein the thermal collector is positioned between the first fuse and the second fuse;
• a first insulating layer that covers a first surface of the first portion;
• and
• a second insulating layer that covers a second surface of the first portion, wherein the second portion is at least partially uncovered by the first insulating layer and the second insulating layer.

A vehicle, comprising:

• a battery subassembly comprising a current collector assembly electrically coupled with one or more battery cells, the current collector assembly comprising:
• a tab electrically coupled with a battery cell of the one or more battery cells;
• and
• a fuse connected to the tab, the fuse comprising a first portion extending along a first direction and having a first width, the fuse further comprising a second portion extending along a second direction different from the first direction and having a second width greater than the first width;
• a first insulating layer;
• and
• a second insulating layer, wherein the first portion is enclosed by the first insulating layer and the second insulating layer, and the second portion extends from the first insulating layer and the second insulating layer, wherein the second portion widens from the second width as the second portion extends away from the first insulating layer and the second insulating layer, and wherein:
• the second insulating layer comprises an edge portion, and
• the second portion bends over the edge portion.
