Noise inflow analysis apparatus and method

An electromagnetic noise penetration analysis apparatus for analyzing electromagnetic wave noise penetrating a battery management device that manages at least one battery module and has a plurality of electrical components represented by a plurality of function blocks, the apparatus comprising:

• at least one near-field measurement probe positioned adjacent to at least one electrical component of the plurality of electrical components associated with first monitoring data identified as operating abnormally during an electromagnetic wave immunity test among the plurality of electrical components represented by the plurality of function blocks, and configured to measure an intensity of magnetic field while electromagnetic noise of a frequency applied when the first monitoring data was obtained during the electromagnetic wave immunity test is applied to the battery management device;
• and
• an analyzer configured to quantify intensity of electromagnetic wave noise penetrating to reach the at least one electrical component represented by at least one function block based on intensity of the magnetic field measured by the at least one near-field measurement probe.
