Interconnecting structure for energy storage cells

An energy storage device comprising:

• a cell holder assembly;
• energy storage cells disposed in the cell holder assembly;
• and
• interconnect members that connect with the energy storage cells, wherein
• the interconnect members include:
• double row interconnecting structures disposed on opposite sides of the cell holder assembly;
• and
• a pair of single row terminal interconnecting structures that border the double row interconnecting structures on both sides,
• wherein each single row terminal interconnecting structure terminates with a first independent arm and a second independent arm,
• wherein two openings are formed in the first independent arm configured for withdrawing current, and
• wherein one opening is formed in the second independent arm configured for measuring voltage,
• each of the interconnect members includes a first independent metallic layer member and a second independent metallic layer member that are electrically coupled to each other and that electrically connect to the energy storage cells,
• the first independent metallic layer member is an upper member of each interconnect member that connects the interconnect member with a battery management system (BMS),
• the second independent metallic layer member is a lower member of each interconnect member that connects the interconnect member with the energy storage cells,
• the first independent metallic layer member is made of copper and provides a current flow passage, and
• the second independent metallic layer member is made of Nickel and establishes a joint to terminals of the energy storage cells.
