METHOD FOR STANDARDING MEASUREMENT LOCATION OF AC-IMPEDANCE

摘要

The present invention provides a method for standardizing a measurement location of an AC-impedance in order to prevent the occurrence of a deviation in an AC impedance measurement value of a vehicle battery by the measurement location through standardizing the measurement location to measure batteries at the same location in inspection of the products. The method comprises the steps of: applying an AC-voltage to a secondary battery; and standardizing the measurement location in order to measure the battery at the same location.
