VOLTAGE MEASURING DEVICE AND BATTERY PACK SYSTEM

A voltage measurement device (100) for independently detecting the voltage of each of a plurality of battery cells (B1, etc.) of a battery pack (200) in which the plurality of battery cells (B1, etc.) are connected in series by n (an integer of 2 or more), the voltage measurement device (100) being provided with: n + 1 resistive elements (R1, etc. The first terminal is connected to a positive electrode of an uppermost battery cell (Bn) among the plurality of battery cells (B1 etc.), a negative electrode of a lowermost battery cell (B1) among the plurality of battery cells (B1 etc.), and contacts between the plurality of battery cells (B1 etc.). N + 1 capacitors (C1 etc.), the first terminals of which are connected to the second terminals of the n + 1 resistive elements (R1 etc.); and a voltage measurement unit (30) connected to the second terminals of the n + 1 resistive elements (B1, etc.). Second terminals of two or more of the (n + 1) capacitors (C1 etc.) are connected to a positive electrode of a kth (k i
