Battery Lifespan Estimation Device And Method

Abstract: This battery lifespan estimation device comprises: a charging/discharging unit for charging/discharging a battery; and a controller which charges/discharges the battery in a partial voltage section defined as the section from a first voltage to a second voltage, so as to calculate a partial cumulative capacity corresponding to the partial voltage section, and which inputs the first voltage, the second voltage and the partial cumulative capacity into an estimation model trained on the basis of machine learning, so as to estimate a lifespan corresponding to the entire voltage section of the battery.
