APPARATUS AND METHOD FOR CALCULATING PRECHARGE RESISTANCE OF BATTERY PACK

摘要

Disclosed are an apparatus and a method for calculating a precharge resistance of a battery pack. The apparatus for calculating a precharge resistance of a battery pack according to the present invention includes: a load resistor configured to be connected between a battery pack and a precharge resistor in series; a voltage measuring unit configured to measure a no-load voltage in a no-load state in which the load resistor is not installed in the battery pack or a load voltage applied to the load resistor when the load resistor has a predetermined current value in a load state in which the load resistor is installed in the battery pack; and a precharge resistance calculating unit configured to calculate the precharge resistor of the battery pack using the no-load voltage of the battery pack, the load voltage, and the predetermined current value.
