Abstract
An apparatus for diagnosing a fault for a lithium-air battery based power supply device includes a data collection part configured to collect data by measuring operational state changes occurring in the power supply device components for each type of fault, a training part configured to train a neural network model using the collected data to classify the type of fault, and a fault diagnosis part configured to diagnose the type of fault by inputting residual changes of each component during operation of the power supply device as input values for the trained neural network model.
