Method for operating a rechargeable battery cell and battery control device

Abstract

The invention relates to a method for operating a rechargeable battery cell: wherein —a first measurement (101) of a first voltage of the battery cell is carried out, —a first comparison (102) of the first voltage with a first limit voltage is carried out, —a charging process (104) of the battery cell is carried out if the first voltage is less than the first limit voltage, —a second measurement (106) of a second voltage of the battery cell is carried out, —a second comparison (107) of the second voltage with a second limit voltage is carried out, —a discharge process (109) of the battery cell is carried out if the second voltage is greater than the second limit voltage, wherein the first limit voltage is greater than the second limit voltage. The invention also relates to a battery control device which is equipped to carry out the method according to the invention.
