  "textContent": "A precharge resistor protection apparatus including a sensing unit configured to measure a battery voltage applied to both ends of a battery cell included in the battery pack and a precharge current flowing in the precharge resistor, and a processor operably coupled to the sensing unit. The processor calculates a first power estimated as being supplied to the precharge resistor and a second power supplied to the precharge resistor during a driving time of the precharge circuit unit by using at least one of a capacitance of a capacitor connected to both ends of the battery pack, the battery voltage and the precharge current, compares a reference power range according to the first power with the second power, and controls an operation state of the precharge relay based on the comparison result.",
