Apparatus for diagnosing battery and method thereof

A battery diagnosing apparatus comprising:

• a memory configured to store program instructions;
• and
• a processor configured to execute the program instructions;
• wherein the program instructions comprise:
• calculating an integral value based on first data, and second data within a predetermined range;
• calculating a Full Width at Half Maximum (FWHM) value associated with a width of the second data relative to half a peak value of the first data;
• and
• determining a condition of a battery cell based on the integral value and the FWHM value;
• wherein the first data includes at least one of:
• a rate of change of pressure of the battery cell;
• an acceleration of the rate of change of the pressure;
• or any combination thereof;
• and
• wherein the second data includes at least one of:
• an areal capacity comprising a capacity per unit area of an electrode plate of the battery cell;
• a charging time of the battery cell;
• or any combination thereof;
• and
• stopping charging the battery cell upon determining that the extent of dendrite formation at an electrode of the battery cell exceeds a predetermined threshold value.
