The present invention relates to a method for measuring an electric vehicle battery remaining life. More specifically, provided is the method for measuring the remaining life of a battery through a temperature, a charge/discharge cycle, and a discharge rate parameter. The method for measuring the spent battery remaining life according to one embodiment of the present invention comprises the following steps of: measuring an initial capacity of the battery; measuring a battery temperature and the number of charge and discharge cycles after the battery has been used for more than a certain period of a time; measuring a remaining capacity of the battery after the same has been used for the certain period of the time based on the battery temperature and the number of charge and discharge cycles; and measuring the remaining life of the battery based on a difference between the initial capacity of the battery and the remaining capacity.
본 발명은 전기차 배터리 잔존수명 측정방법에 관한 것으로, 보다 상세하게는 온도, 충방전 싸이클 및 방전율 파라미터를 통해 배터리의 잔존수명을 측정할 수 있는 방법을 제공하고자 한다. 본 발명의 일 실시예에 따른 폐배터리 잔존수명 측정방법은, 배터리의 초기용량을 측정하는 단계와, 상기 배터리가 일정기간 이상 사용된 이후의 배터리 온도와 충방전된 사이클 횟수를 측정하는 단계와, 상기 배터리 온도와 충방전된 사이클 횟수로부터 일정기간 이상 사용된 이후 배터리의 잔존용량을 측정하는 단계 및 상기 배터리의 초기용량에서 잔존용량의 차를 기초로 배터리의 잔존수명을 측정하는 단계를 포함한다.
