Abstract

See full text

Systems and methods are described herein for reducing electromagnetic interference (EMI) affecting measurements of a battery module monitoring board. A battery module system includes battery cells on a top side and a bottom side of the battery module. Each battery cell is electrically coupled between an adjacent pair of busbars. Each busbar is coupled to at least one sensor wire. One busbar, which spans the top and bottom sides of the battery module, is coupled to two sensor wires such that EMI interference affecting measurement signals (e.g., noise signals accompanying voltage readings) associated with the top side of the battery module are in-phase with one another and the measurement signals associated with the bottom side of the battery module are in-phase with one another, such that the EMI interference generally cancels in measurement calculations.
