The present invention relates to circuit for measuring battery voltage and method for battery voltage measurement using the same. In the circuit for measuring battery voltage and method for battery voltage measurement using the same, three or more capacitors, which form a closed loop and are sequentially connected, are provided, and voltages of voltage sources are measured by using the three or more capacitors in turn, which prevents measurement errors from occurring due to residual charges in the capacitors and enables more precise measurement. Further, according to the present invention, since the three or more capacitors are alternately charged and discharged, the delay in time is decreased, and the voltages of the plurality of voltage sources can be measured at one time. Therefore, it is possible to reduce the amount of time required to measure battery voltage.
