Battery Module including Asymmetric Cell Electrical Connections

A battery module comprising:

• a module first terminal, the module first terminal having a first polarity,
• a module second terminal, the module second terminal having a second polarity that is opposite the first polarity,
• electrochemical cells, each cell comprising a first end that includes a cell first terminal having the first polarity, a second end that is opposed to the first end and includes a cell second terminal having the second polarity, and a sidewall that extends between the first end and the second end,
• a first bus bar that electrically connects the cell first terminals of at least a subset of the cells to the module first terminal, and
• a second bus bar that electrically connects the cell second terminals of the subset of the cells to the module second terminal,
• a first electrical connector that electrically connects the first bus bar to a cell first terminal of each cell of the subset of the cells, the first electrical connector having a first current carrying capacity, and
• a second electrical connector that electrically connects the second bus bar to a cell second terminal of each cell of the subset of the cells, the second electrical connector having a second current carrying capacity,
• wherein the first current carrying capacity is different than the second current carrying capacity.
