The device can include a current sensor to measure a discharge current output from a rechargeable battery during a discharge period in which the rechargeable battery is discharged from a predetermined reference voltage with a constant voltage, and a control circuit to calculate a resistance change relationship depending on a State of Charge (SOC) change during the discharge period based on the predetermined reference voltage and a change of the discharge current depending on time passage.",
