| Abstract | According to an embodiment of the present invention, a battery voltage measuring device includes: a plurality of battery modules each comprising a plurality of battery cells; a bus bar connected between the battery modules; and a voltage measuring unit which measures a voltage for each of the battery cells included in the battery module and the bus bar. According to the present invention, influence on the voltage measurement of the battery cell by current flowing through the bus bar can be reduced, and a diagnosis can be performed using the voltage measured for each bus bar.
