Abstract
An apparatus for calculating battery resistance according to an embodiment of the present invention can include a measurement circuit connected between one terminal among a positive (+) terminal and a negative (−) terminal of a battery pack and a chassis, a voltage measurement unit that measures a voltage from the measurement circuit, and an insulation resistance calculation unit that calculates insulation resistance of the battery pack based on the voltage measured by the voltage measurement unit. When the calculated insulation resistance is less than a preset threshold, the insulation resistance calculation unit can recalculate the insulation resistance based on an amount of change in voltage of the battery pack over time.
