System for providing voltage measurements of battery cells to a PCB within a battery module

摘要

A battery module and a method of manufacture are provided. The battery module may include a printed circuit board (PCB) assembly. The PCB assembly may include a PCB designed to be disposed in a battery module for controlling operations of the battery module. The PCB may also include voltage sensing circuitry. In addition, the PCB assembly may include a bus bar cell interconnect. The bus bar cell interconnect may electrically couple batteries of the battery module. The PCB assembly may also include a voltage sense connection tab. The voltage sense connection tab may carry a voltage between a bus bar cell interconnect of the battery module and the voltage sensing circuitry on the PCB.
