Battery cell for electric vehicle battery pack

A method of providing battery packs, comprising:

• forming a housing for a battery cell of a battery pack having a plurality of battery cells, the housing having a closed end and an open end, the open end defining a lip;
• providing a first polarity terminal at a lateral end of the housing, the housing defining a lip that surrounds the first polarity terminal;
• electrically coupling a bridge with the lip of the housing to form a second polarity terminal, the bridge extending over a portion of the first polarity terminal;
• providing a busbar comprising a first conductive layer having a first opening aligned with the lip and a second conductive layer having a second opening;
• electrically coupling the bridge with the first conductive layer of the busbar via a first wire;
• and
• electrically coupling the first polarity terminal with the second conductive layer of the busbar via a second wire.

An electric vehicle, comprising:

• a battery pack installed in the electric vehicle to power the electric vehicle, the battery pack comprising:
• a battery cell comprising:
• a first polarity terminal disposed at a lateral end of the battery cell;
• a housing having a closed end and an open end, the open end defining a lip that surrounds the first polarity terminal;
• a second polarity terminal comprising the lip;
• a bridge electrically coupled with the lip and extending over a portion of the first polarity terminal;
• a busbar comprising:
• a first conductive layer having a first opening aligned with the lip;
• a second conductive layer having a second opening;
• a first wire having a first end and a second end, the first end of the first wire bonded with the bridge, the second end of the first wire bonded with the first conductive layer to electrically couple the second polarity terminal with the first conductive layer;
• and
• a second wire having a first end and a second end, the first end of the second wire bonded with the first polarity terminal, the second end of the second wire bonded with the second conductive layer to electrically couple the first polarity terminal with the second conductive layer.
