Document Type and Number:

WIPO Patent Application WO/2024/100975

Kind Code:

A1

Abstract:

A secondary battery model parameter generation method according to one aspect of the present technology comprises the following four: (1) intermittently charging a secondary battery to a second voltage after discharging the secondary battery to a first voltage; (2) measuring the voltage and current of the secondary battery during the discharging and the intermittent charging of the secondary battery; (3) estimating a model parameter of a battery model on the basis of a voltage value and a current value of the secondary battery obtained during the intermittent charging; and (4) comparing the voltage value of the secondary battery obtained during the discharging with a voltage value at the time of discharging obtained from the battery model to which the model parameter obtained by the estimating is applied, to determine the accuracy of the battery model.
