Device and method for battery detection, and battery reliability inspection method thereof

Abstract

A battery detection device includes: a sensing unit, to sense voltage, current, and discharge time of a battery during its discharge process at a specific temperature; and a processing unit, determining a reaction rate coefficient based on the battery's voltage, current, and discharge time, for determining or predicting the battery’s health degradation state according to the reaction rate coefficient; wherein, a higher value of the reaction rate coefficient corresponds to a greater deterioration in the battery’s health degradation status, thereby predicting a higher possibility of abnormal battery conditions.
