1. A battery pack management method for HEV and EV, the method comprising steps of:

  • applying power for a control signal to a relay of a battery pack connection circuit through a battery management system (BMS) or vehicle control device;

    detecting current or voltage from a pre-charge resistor of the battery pack connection circuit;

    comparing the detected current or voltage 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; and

    carrying out a normal charging operation when the detected value is within the normal range as a result of the determination, otherwise turning off a pre-charge relay of the battery pack connection circuit and then providing a driver with a warning signal through warning means electrically connected to the BMS.
