Busbar assembly

A method of manufacturing a battery pack, the method comprising:

• providing a casing;
• providing at least one row of battery cells;
• and
• attaching a respective busbar assembly to each row of the least one row of battery cells and to the casing, wherein the respective busbar assembly comprises:
• an elongated support structure having a length direction and a defined width, the elongated support structure comprising:
• a bottom wall,
• two side walls, extending in the length direction along longitudinal sides,
• two spaced-apart central ridges extending in the length direction,
• a signal line, connected to the elongated support structure between the central ridges,
• conductor members positioned between the side walls and an adjacent central ridge, adapted for interconnecting terminals of battery cells that are adjacent in the length direction,
• wherein the side walls and the central ridges each extend at a cover side from the bottom wall to a connecting plane and define a top adhesive surface strip, the top adhesive surface strips being situated in the connecting plane and adapted for adhesive connection to a top wall of the casing,
• wherein the bottom wall comprises bottom adhesive surface strips that are respectively vertically aligned with the top adhesive surface strips,
• wherein the bottom adhesive surface strips are adhesively bonded to the respective tops of the battery cells, and
• wherein the top adhesive surface strips are adhesively bonded to the top wall of the casing.

An electric vehicle comprising:

• a battery pack comprising:
• a casing with a first bottom wall, two first side walls, and a top wall;
• and
• a defined quantity of rows of battery cells, wherein each battery cell has two spaced-apart electric terminals in a top plane, wherein each row of battery cells is attached to a respective busbar assembly comprising:
• an elongated support structure having a length direction and a defined width, wherein the elongated support structure comprises:
• a second bottom wall,
• two second side walls, extending in the length direction along longitudinal sides,
• two spaced-apart central ridges extending in the length direction,
• a signal line, connected to the elongated support structure between the central ridges,
• conductor members positioned between the second side walls and an adjacent central ridge, adapted for interconnecting terminals of battery cells that are adjacent in the length direction,
• wherein the second side walls and the central ridges each extend at a cover side from the second bottom wall to a connecting plane and define a top adhesive surface strip, the top adhesive surface strips being situated in the connecting plane and adapted for adhesive connection to the top wall of the casing,
• wherein the second bottom wall comprises bottom adhesive surface strips that are respectively vertically aligned with the top adhesive surface strips,
• wherein the bottom adhesive surface strips are adhesively bonded to the respective tops of the battery cells, and
• wherein the top adhesive surface strips are adhesively bonded to the top wall.

A battery system comprising:

• a plurality of battery packs, wherein each battery pack comprises:
• a casing with a first bottom wall, two first side walls, and a top wall;
• and
• a defined quantity of rows of battery cells, wherein each battery cell has two spaced-apart electric terminals in a top plane, wherein each row of battery cells is attached to a respective busbar assembly comprising:
• an elongated support structure having a length direction and a defined width, wherein the elongated support structure comprises:
• a second bottom wall,
• two second side walls, extending in the length direction along longitudinal sides,
• two spaced-apart central ridges extending in the length direction,
• a signal line, connected to the elongated support structure between the central ridges,
• conductor members positioned between the second side walls and an adjacent central ridge, adapted for interconnecting terminals of battery cells that are adjacent in the length direction,
• wherein the second side walls and the central ridges each extend at a cover side from the second bottom wall to a connecting plane and define a top adhesive surface strip, the top adhesive surface strips being situated in the connecting plane and adapted for adhesive connection to the top wall of the casing,
• wherein the second bottom wall comprises bottom adhesive surface strips that are respectively vertically aligned with the top adhesive surface strips,
• wherein the bottom adhesive surface strips are adhesively bonded to the respective tops of the battery cells, and
• wherein the top adhesive surface strips are adhesively bonded to the top wall.
