Abstract

A module interface device for a multi-cell battery module comprises a cathode bus connectable to a cathode terminal and an anode bus connectable to an anode terminal of the battery module, and a set of one or more inter-cell taps connectable to respective inter-cell electrical interconnectors that interconnect neighboring pairs of cells of the battery module. The module interface devices comprises a cell balancing circuit that includes: an electrically conductive pathway that joins the cathode bus with the anode bus, a set of multiple resistive-capacitive elements arranged along the electrically conductive pathway, and a set of one or more switches in which a respective switch is located along each inter-cell tap. Each inter-cell tap joins the electrically conductive pathway at a respective location between a different neighboring pair of resistive-capacitive elements.
