Method and device for estimating parameters for secondary battery |
| abstract |
Disclosed are a method and a device for estimating parameters for a secondary battery. The device according to the present invention comprises: a sensor means which measures a plurality of current-voltage data items while a charged current decreases in a process in which a secondary battery is charged in a pattern where the charged current increases to a peak value and then decreases once again; and a control means which receives the input of the plurality of current-voltage data items from the sensor means, calculates, from the plurality of current-voltage data items, an approximate linear equation showing the correlation between the current and the voltage, estimates the open circuit voltage of the secondary battery by reflecting, on the Y intercept of the approximate linear equation, the polarization potential of the secondary battery quantified via an RC circuit, and estimates the charge state of the secondary battery from the estimated open circuit voltage. |
