Abstract
Disclosed are a voltage measuring apparatus and a battery management system including the same. The voltage measuring apparatus is connected to a plurality of battery cells connected to each other in series to measure respective voltage of the battery cells. The voltage measuring apparatus includes a first node coupled to one of an positive electrode and a negative electrode of one of a plurality of battery cells as a voltage measuring target, amplifies a voltage difference between the first node and the second node to generate an error voltage, converts the error voltage into a digital signal, and compensates for a polarity of the digital signal.
