Title
(EN) Device for estimating a lifetime of a secondary battery and method thereof
Abstract
(EN)

Embodiments of the present invention provide an accelerated lifetime estimation device for predicting the lifetime of a secondary battery, and a method thereof. The accelerated lifetime estimation device can accurately estimate a normal lifetime of the secondary battery while reducing an evaluation time period of the secondary battery.
