Abstract
A battery monitoring method includes identifying a state of charge (SOC) of a battery, obtaining a voltage of the battery with respect to the SOC, in response to the identified SOC being included in a diagnosis section, and determining a state of health (SOH) of the battery based on the obtained voltage of the battery.
