Abstract
A device for estimating a state-of-health (SOH) of a battery module controls a battery current to have a predetermined current value for a testing period such that a battery voltage decreases during the testing period, corrects a voltage variation value of the battery module during the testing period according to a temperature value of the battery module, and estimates the SOH of the battery module according to the corrected voltage variation value, a current variation value of the battery module during the testing period, and a rated capacity of the battery module.
