Abstract (en)
[origin: WO2022146690A1] At least one electrochemical cell is charged to a predetermined voltage of the electrochemical cell using an external power source. A charging current of the at least one electrochemical cell is monitored. An increase in the charging current is detected at the predetermined voltage of the at least one electrochemical cell. It is determined that the at least one electrochemical cell is in danger of experiencing a performance decrease based on the detected increase in the charging current.
