Abstract
A method for estimating a state of health (SOH) of a battery pack includes estimating a number of charge and discharge cycles of the battery pack; calculating a first SOH of the battery pack by using the number of charge and discharge cycles; calculating a number of service years of the battery pack; calculating a second SOH of the battery pack by using the number of service years; calculating a limit discharge capacity of the battery pack; calculating a third SOH of the battery pack by using the limit discharge capacity; and comparing a value of the first SOH, a value of the second SOH, and a value of the third SOH and taking a minimum value as the SOH of the battery pack.
