Abstract
An interconnect board (ICB) assembly is used with a battery module and a battery controller. The ICB assembly includes a printed circuit board assembly (PCBA) integrally formed from a printed circuit board (PCB) and a flex circuit. The PCB has a component surface populated with electronic components which measure and report parameters of the battery module to the battery controller. The flex circuit is constructed of conductive foil, and defines tabular flying leads that project from a periphery of the flex circuit. A window may be present in the flex circuit. A carrier frame has a support surface flanked by busbars. The PCBA is seated on the support surface, with the flying leads conductively joined to a corresponding busbar. A battery system includes the battery controller and the ICB assembly.
