Abstract: A method for monitoring a state of at least one predetermined battery cell of a battery having a number of series-connected or series-connectable battery cells. In one example, the method includes placing the battery, during a first phase, into a first state in which the battery cells in each case have a predefined charging state, discharging the battery, which is in the first state, during a second phase following the first phase, charging the battery during a third phase, following the second phase, up to a point in time at which at least one battery cell of the battery has the predefined charging state, detecting the voltage provided by the at least one predetermined battery cell at least temporarily, and determining information for detecting the state of the at least one predetermined battery cell by evaluating the detected voltage.

Abstract: The invention relates to a method and to a device for measuring a battery cell current through a battery cell unit. After the battery cell unit has been switched off, inductively stored energy from the battery cell unit is discharged (S1) by means of a discharging unit, wherein the inductively stored energy from the battery cell unit is energy stored by means of an inductive behavior of the battery cell unit, a time period in which the inductively stored energy from the battery cell unit has fallen to a predefined threshold value is determined (S2), and a battery cell current is determined (S3) on the basis of the time period determined.
