Abstract

Multiple voltage monitoring circuits each detect the voltage across at least one corresponding cell from among multiple cells. A current monitoring circuit detects the current that flows through the multiple cells. When the length of a period during which the current that flows through the multiple cells is substantially zero exceeds a predetermined judgment time, the current monitoring circuit asserts a detection signal. Upon detecting an assertion of the detection signal, each voltage monitoring circuit measures the voltage across at least one corresponding cell.
