Abstract

In a method for operating a battery, e.g., in a driverless transport vehicle, the battery is charged in a charging process starting from a start time; during the charging process at a number of measurement times a charging current flowing through the battery, a battery voltage applied to the battery and a battery temperature prevailing in the battery are measured; an amount of charge introduced into the battery is calculated from the charging current; a voltage gradient is calculated from the battery voltage and the amount of charge; a first end criterion is determined from a curve of the voltage gradient; a temperature gradient is calculated from the battery temperature and the amount of charge; a second end criterion is determined from a curve of the temperature gradient; a temperature increase is calculated from a curve of the battery temperature; a third end criterion is determined if the temperature increase exceeds a threshold value; and the charging process is ended after at least one of the end criteria is present.
