Apparatus and method for estimating parameter of secondary battery |
| abstract |
Disclosed is an apparatus and method for estimating a parameter of a secondary battery. The apparatus according to the present disclosure includes a sensor means configured to measure a plurality of current-voltage data while a charging current decreases when a secondary battery is charged in such a pattern that the charging current increases to a peak value and then decreases, and a control means configured to receive an input of the plurality of current-voltage data from the sensor means, calculate a linear approximation equation representing a correlation between a current and a voltage from the plurality of current-voltage data, estimate an open-circuit voltage (OCV) of the secondary battery by reflecting a polarization voltage of the secondary battery quantified through a resistor-capacitor (RC) circuit on a Y intercept of the linear approximation equation, and estimate a state of charge (SOC) of the secondary battery from the estimated OCV. |
