Abstract

A battery system includes: a plurality of battery cells electrically connected to each other in series between a first node and a second node; an intermediate node dividing the plurality of battery cells into a first subset of battery cells and a second subset of battery cells; a step-down converter connected in parallel with the plurality of battery cells between the first node and the second node and having an output node; a first diode, an anode of which is connected to the intermediate node and a cathode of which is connected to the output node; and a control unit interconnected between the output node and the first node and configured to control the step-down converter.
