Abstract
Provided is a device for estimating secondary cell status using multiple models. The device for estimating secondary cell status uses multiple models, model 1, model 2, and model 3, to estimate the status of respective secondary cells. An arithmetic unit compares the estimated voltage values obtained from model 1, model 2, and model 3 with measured voltage values, sets the model having the highest correlation as the optimal model, optimizes the parameters of such model, and estimates secondary cell status.
