Abstract
An apparatus for measuring a battery cell voltage includes a battery having a cell group; a first switching unit for selectively connecting both terminals of each battery cell of the cell group to conductive lines; a first voltage charging unit connected between the conductive lines to primarily charge a cell voltage; a second voltage charging unit for relaying the charged voltage in the first voltage charging unit for secondary charging; a cell voltage sensing unit for sensing the voltage charged in the second voltage charging unit; and a second switching unit for interconnecting the voltage charging units in the charged voltage relaying mode and isolating the voltage charging units in the charged voltage sensing mode. This apparatus realizes isolation between a high voltage battery and a voltage sensing unit, thereby allowing voltage sensing of each battery cell included in a high voltage battery using a part with low withstanding voltage.
