A method of monitoring a high-voltage battery provided in an electric vehicle (EV) may check the state of a high-voltage battery and a low-voltage battery, actively perform monitoring at a time when monitoring is required, such as when the low-voltage battery is in good condition and the high-voltage battery is slightly degrading. When an aging state of the high-voltage battery and the low-voltage battery progresses, the method may change accordingly a monitoring repetition period to reduce the power consumption compared to the same monitoring time or reduce the total monitoring time to reduce the power consumption, thereby preventing the low-voltage battery used as an auxiliary battery from being fully discharged.
