Abstract
A method for estimating a state of health of a battery includes calculating a measured value of a charging required time for each of preset voltage intervals in a preset voltage range in which the battery is charged; calculating an estimated value of the charging required time for each of the voltage intervals by a preset battery meta-model; and estimating the SOH having lowest error between the measured value of the charging required time and the estimating value of the charging required time by allowing the estimated value of the charging required time to iteratively approach the measured value of the charging required time.
