Method and apparatus for adjusting value of current of battery

An electronic device for adjusting a value of a current of a battery, the electronic device comprising:

• a memory configured to store a program;
• and
• a processor configured to execute the program to configure the electronic device to obtain values of one or more basic parameters of a battery comprising the current of the battery, a voltage of the battery, and a temperature of the battery;
• determine a value of a first correction parameter relating to a variation in current due to charging and discharging of the battery, based on at least a portion of the values of the one or more basic parameters;
• determine a difference between an electrolyte concentration of an anode surface and an electrolyte concentration of a cathode surface of the battery, based on at least a portion of the values of the one or more basic parameters;
• determine a value of a temperature parameter based on the temperature of the battery;
• determine a value of a second correction parameter relating to a temperature of the battery, based on a variation of the difference and the value of the temperature parameter;
• determine a correction value of the current by adjusting an initial value of the current, based on the value of the first correction parameter and the value of the second correction parameter;
• apply the correction value to a battery model for estimating an internal state of the battery;
• and
• control the charging or discharging of the battery using internal state conditions defined based on the internal state of the battery.
