Abstract
A sensing circuit for battery cell voltage may include a first cell module including a plurality of battery cells; a first sensor sensing voltage of each battery cell of the first cell module; and a first isolation relay device including a plurality of relays, determining an electrical connection state between each battery cell of the first cell module and the first sensor by being connected thereto, and maintaining isolation between the first cell module and the first sensor.
