Disclosed is a method of evaluating a residual value of an EV battery. Provided is a method, in which in order to shorten a process time, SOH is calculated under partial discharge which occurs in the (state of charge, SOC) of the battery rather than complete discharge, in evaluating a residual value of an EV battery by calculating (state of health, SOH) of the battery, (state of available power capability, SOP) of the battery, and cell voltage deviation (state of balance, SOB).
전기차 배터리 잔존가치 평가 방법이 개시된다. 이 방법은 배터리의 용량수명(state of health, SOH)과 파워수명(state of available power capability, SOP) 및 셀 전압편차(state of balance, SOB)를 산출하여 전기차 배터리의 잔존가치를 평가함에 있어서, 공정 시간의 단축을 위해 완전방전이 아닌 소정의 배터리 용량(state of charge, SOC) 구간에서 이루어지는 부분방전 하에 SOH를 산출한다.
