METHOD AND DEVICE FOR DETERMINING THE DEGRADATION OF A BATTERY MODULE OR BATTERY CELL

Method for determining the degradation of a battery module or a battery cell, wherein the battery module or battery cell delivers energy to an electric load and following steps are comprised:a) Capturing a battery parameter set (10) comprising an actual temperature (11) of the battery module (110),b...

description Method for determining the degradation of a battery module or a battery cell, wherein the battery module or battery cell delivers energy to an electric load and following steps are comprised:a) Capturing a battery parameter set (10) comprising an actual temperature (11) of the battery module (110),b) Capturing a load parameter set (20),c) Capturing an environmental parameter set (30),d) Setup and training a machine learning model (40) with the battery parameter set (10), the load parameter set (20) and the environmental parameter set (30),e) Calculating a predicted temperature (41) and a standard deviation (42) using the machine learning model (40),f) determining the degradation of a battery module (110) using predicted temperature (41), the standard deviation (42) and the actual temperature (11).
