Title: METHOD AND DEVICE FOR MEASURING A BATTERY CELL CURRENT
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.
