Abstract

The present invention relates to a method for predicting a status of a battery cell (12) of an electrical energy storage device of a motor vehicle by a management device (14) of the electrical energy storage device (10), the method comprising the steps of detecting at least one parameter (24, 26, 28, 30) of the battery cell (12) by a detecting device of the management device (14), determining a mathematical model (22) for a metal anode of the battery cell (12) by an electronic computing device (34) of the management device (14), and predicting the status of the battery cell (12) by the electronic computing device (34) based on the parameter (24, 26, 28, 30) and the mathematical model (22). Furthermore, the present invention relates to a corresponding management device (14) and non-transitory computer readable medium.
