A method of protecting a precharge resistor provided in a battery pack, including attempting a first attempt to charge a precharge capacitor, the precharge capacitor being electrically connected to two ends of a battery module provided in the battery pack and charged by receiving a precharge current from the battery module, adding predetermined penalty points to a summed penalty point total based on a result of the first attempt to charge the precharge capacitor determining whether the precharge resistor is in a limited state based on the summed penalty point total, and preventing a second attempt to charge the precharge capacitor for a predetermined time if the precharge resistor is in the limited state.
