Abstract:
A system and method for more accurately measuring an internal resistance of a battery for a vehicle are provided. The method includes measuring, by a controller, current-voltage pairs for the battery and calculating a correlation between current and voltage in the measured current-voltage pairs. In addition, the internal resistance of the battery is measured using the current-voltage pairs having the correlation equal to or greater than a preset threshold.
