Title:
BATTERY PARAMETER ESTIMATION DEVICE AND PARAMETER ESTIMATION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/059879
Kind Code:
A1
Abstract:
 Provided are a battery parameter estimation device and a parameter estimation device for estimating parameters of an equivalent circuit model of a battery, at reduced computational load. The device is provided with a charge/discharge current detection unit (3) for detecting a charge/discharge current value of a battery (1), a terminal voltage detection unit (2) for detecting a terminal voltage value of the battery (1), and an estimation unit (4) which, on the basis of the charge/discharge current value and the terminal voltage value, estimates parameters in a battery equivalent circuit model (41) that approximates the Warburg impedance of the battery (1).
