Abstract
A system for a vehicle may include a first battery pack diagnosis apparatus connected to a first battery pack, a second battery pack diagnosis apparatus connected to a second battery pack, a third battery pack diagnosis apparatus connected to a third battery pack, and a fourth battery pack diagnosis apparatus connected to a fourth battery pack. The first battery pack diagnosis apparatus may be configured to determine, based on a measured value of an integrated insulation resistance of an inverter terminal associated with the vehicle, whether a battery, of the first battery pack, the second battery pack, the third battery pack, or the fourth battery pack, is in a failure state, and based on a determination that the battery is in the failure state and based on individually measured insulation resistance of the first-fourth battery packs, determine a failure position of the battery.
