Abstract
A battery module includes a housing, a plurality of battery cells disposed in the housing, and a printed circuit board (PCB) assembly disposed in the housing. The PCB assembly includes a PCB and a shunt disposed across a first surface of the PCB. A second surface of the shunt directly contacts the first surface of the PCB, and the shunt is electrically coupled between the battery cells and a terminal of the battery module.
