METHOD FOR DETERMINING AN ELECTRICAL CELL VOLTAGE OF A BATTERY CELL OF A TRACTION BATTERY OF A VEHICLE AND DEVICE

摘要

The invention relates to a method for determining an electrical cell voltage of a battery cell of a traction battery of a vehicle, in which, in order to provide a cell voltage signal which describes the cell voltage of the battery cell, the cell voltage of the battery cells is filtered with a filter device (3) and the filtered cell voltage is scanned with an analog-digital converter (4), wherein the cell voltage signal is evaluated, wherein a ripple value is also provided, which describes a ripple of the cell voltage, and the cell voltage signal is evaluated according to the ripple value.
