Abstract
A method for charging a battery includes: determining a first charging section, in which a current charging rate of the battery is located, from among a plurality of charging sections predetermined based on a functional relation between a state of charge of the battery and an open circuit voltage of an anode of the battery; and charging the battery for the first charging section with a first charging rate corresponding to the first charging section.
Claims16
A method for charging a battery, the method comprising:
- monitoring a state of the battery;
- determining, based on the monitored state of the battery, a current charging stage among a plurality of charging stages to which both a multi-stage constant current charging scheme and a single stage constant voltage charging scheme are applied, wherein the plurality of charging stages is consecutive stages in which the battery is charged with different constant charging rates, respectively;
- charging the battery during the current charging stage with a current charging rate corresponding to the current charging stage;
- and
- charging the battery during a next charging stage with a next charging rate corresponding to the next charging stage based on a potential difference between a potential of an anode of the battery and a potential of an electrolytes solution of the battery in the current charging stage being determined to be equal to or less than a predetermined value.
