A method for estimation of state-of-health (SOH) characteristics of a battery in hybrid vehicles includes charging and discharging the battery at least one time within an upper region of a state-of-charge (SOC) window, wherein the battery; charging and discharging the battery at least one time within a lower region of the SOC window, calibrating a battery management unit included in the hybrid vehicle by using the reached levels outside the SOC window, and estimating the SOH characteristics of the battery during the charge and discharge periods by using the battery management unit.
