METHOD OF DETERMINING STATE-OF-CHARGE OF BATTERY

摘要

PURPOSE: A method for determining the state of charge of a battery is provided to measure the state of charge of a battery in a short time through a simple method. CONSTITUTION: The impedance of a battery is measured. The parameter of devices constituting the equivalent circuit of the battery is measured based on the measured impedance. The first state of charge of the battery is determined by using a first parameter among determined parameters.
