Abstract
A learning method of an open circuit voltage estimation model includes training the open circuit voltage estimation model to learn a relationship of the open circuit voltage estimation input data obtained by preprocessing terminal currents and terminal voltages of a secondary battery with an open circuit voltage of the secondary battery. The open circuit voltage estimation input data includes time-series data of: the terminal currents; the terminal voltages; and difference gradients of terminal voltage differences with respect to terminal current differences.
