Abstract
Provided is a method for diagnosing a state of reusable (SOR) of a battery and, more specifically, to a method for diagnosing an SOR of a battery, the method being capable of diagnosing the overall state of a battery during battery reuse by separately diagnosing a state of health (SOH) and a state of power (SOP) of the battery.The method for diagnosing a state of reusable (SOR) of a battery according to the present invention includes: estimating a state of charge (SOC) according to a change in an open circuit voltage (OCV); estimating a state of health (SOH) by using the SOC; calculating a state of power (SOP) in consideration of an output of a current battery; and calculating the SOR by using the SOH and the SOP.
