According to one embodiment of the present invention, a battery life estimation device may include a charging unit that charges a battery based on a charging cycle including a pulse section for applying a pulse current to a battery, a CC (constant current) charging section, and a CV (constant voltage) charging section, wherein the pulse section is a section before the CC charging section, a sensor unit that measures a voltage change of the battery and a current change of the battery during the pulse section, and a DCIR calculating unit that calculates a DCIR (direct current internal resistance) of the battery based on the voltage change and the current change.

    본 문서에 개시된 일 실시 예에 따른 배터리 수명 추정 장치는, 배터리에 펄스 전류를 인가하는 펄스 구간, CC(constant current) 충전 구간, 및 CV(constant voltage) 충전 구간을 포함하는 충전 사이클에 기반하여 배터리를 충전하는 충전부, 상기 펄스 구간은 상기 CC 충전 구간 전의 구간이고, 상기 펄스 구간 동안의 상기 배터리의 전압 변화 및 상기 배터리의 전류 변화를 측정하는 센서부, 및 상기 전압 변화 및 상기 전류 변화에 기반하여 상기 배터리의 DCIR(direct current internal resistance)을 산출하는 DCIR 산출부를 포함할 수 있다.
