Method, Apparatus, System, Electric Vehicle, Computer Program and Storage Medium for Charging or Discharging a Cell of an Electric Energy Store

A method for charging a cell of an electric energy store includes setting the cell into a charging mode; determining a first and a second impedance characteristic, each representative of a complex alternating current impedance of the cell; determining a first and a second temperature characteristic on the basis of the impedance characteristics, each representative of a temperature of the cell; determining a deviation in the temperature characteristics; and reducing a charging current of the cell in the event that the deviation exceeds a specified temperature threshold value.
