Abstract
Disclosed is a battery pack management method for HEV and EV. Power for a control signal is applied to a relay of a battery pack connection circuit through a battery management system (BMS) or vehicle control device. Then, current or voltage from a pre-charge resistor of the battery pack connection circuit is detected. Thereafter, the detected current or voltage is compared with standard correspondence information pre-stored in a memory unit of the BMS to determine whether the detected value is within a normal range of the battery pack. A connection between the battery pack and the power conversion circuit is carried out when the detected value is within the normal range as a result of the determination, otherwise a pre-charge relay of the battery pack connection circuit is turned off and then a driver is provided with a warning signal.
