An apparatus and method for detecting battery pack voltage is disclosed. The voltage detection apparatus includes a plurality of selectors for providing a cell voltage of a predetermined cell, a detector buffer for receiving the cell voltage of the predetermined cell and supplying an intermediate voltage, a data process circuit for processing the intermediate voltage to acquire a voltage value indicative of the cell voltage of the predetermined cell, wherein each selector includes a plurality of switches and a plurality of level shifters, each switch being controlled by one of the plurality of level shifters to operate with a safe gate-source voltage, source-bulk voltage and reverse-biased body diode.
