Abstract

To improve the full charge capacity estimation accuracy.SOLUTION: A full charge capacity estimation method includes a step A of acquiring battery data and processing the acquired data, a step B of extracting data, and a step C of estimating the full charge capacity of a battery to be measured. The step A includes acquiring battery data including a voltage value, a current value, and a temperature value, which can be obtained over time from the battery to be measured, and processing the acquired data. The step B includes extracting data equal to or greater than n satisfying a predetermined condition from at least one of the acquired data in the step A and the data obtained by the processing in the step A. The step C includes estimating the full charge capacity of the battery to be measured on the basis of the data extracted in the step B. Here, n is an integer equal to or greater than 3.SELECTED DRAWING: Figure 2
