The voltage monitoring module includes an input terminal, a cell balancing input terminal, a switch, and a control circuit. The input terminal is coupled to a high-voltage-side terminal of a battery cell through a filter resistor. The cell balancing input terminal is coupled to the high-voltage-side terminal of the battery cell. The switch is coupled to the input terminal. The control circuit- controls ON/OFF of the switch. A filter resistor is coupled between the switch and a ground. The control circuit turns on the switch, so that a high-voltage-side voltage is compared with a low-voltage-side voltage.
