Abstract
Provided is an inter-module voltage balance correcting circuit of a power storage system including a plurality of storage modules connected in series, each of the storage modules including a plurality of storage cells connected in series. The inter-module voltage balance correcting circuit includes a resistance voltage dividing circuit (R-R) that equally divides a series voltage across a first storage module and a second storage module connected in series; and a pair of transistors that are turned ON/OFF complementarily based on a voltage (Vp-Vp) appearing between an intermediate connecting point (p) between the storage modules M, Min series and a voltage dividing point pof the resistance voltage dividing circuit, and a bypass discharge resistive element is selectively connected to modules by turning ON/OFF the complementary transistors.
