Abstract
The present invention relates to a battery parameter management system and a battery parameter estimation method which are capable of simply estimating parameters of elements forming a battery equivalent model having a simple structure. The battery parameter system includes an amperemeter, a voltmeter, a control switch unit, and a processor, and the battery parameter estimation method includes supplying a pulse current, estimating resistance of an internal resistor, estimating capacitance of an internal capacitor, and estimating parameters of dynamic elements.
