Abstract: Proposed are a real-time battery monitoring apparatus and method using transient response analysis. The real-time battery monitoring apparatus may include a monitoring circuit connected to a battery and a processor. The processor may be configured to determine deterioration of the battery by controlling the monitoring circuit to measure a voltage and a current of the battery, estimate an internal resistance of the battery based on the measured voltage and current, and compare the estimated internal resistance with a pre-set threshold value.
