Claim Text:
1. A method of electrically interconnecting a plurality of batteries, said method comprising: fabricating a bus bar, said bus bar comprising a plurality of interconnects configured to include at least one interconnect per battery of said plurality of batteries, said at least one interconnect comprising: pre-shaping said sacrificial contact and said primary contact prior to contacting said at least one interconnect to said battery terminal, wherein said step of pre-shaping creates a first separation distance between a first contact surface corresponding to said sacrificial contact and said battery terminal, and creates a second separation distance between a second contact surface corresponding to said primary contact and said battery terminal, wherein said second separation distance is greater than said first separation distance; contacting said first contact surface corresponding to said sacrificial contact to said battery terminal; contacting said second contact surface corresponding to said primary contact to said battery terminal, wherein said step of contacting said second contact surface to said battery terminal is performed after completion of said step of contacting said first contact surface to said battery terminal; and attaching said primary contact to said battery terminal, wherein said step of attaching forms an electrical connection between said primary contact and said battery terminal.
