Method for Determining a Thermal Runaway of an Electric Energy Storage Unit of an at Least Partially Electrically Operated Motor Vehicle, Computer Program Product, and Electronic Computing Device

Abstract: a method for determining a thermal runaway of an electric energy storage unit of an operated motor vehicle includes continuous monitoring of the electric energy storage unit by at least one diagnostic method of an electric energy storage unit based on a diagnostic signal, determining a frequency of the anomaly when the anomaly is detected in the diagnostic signal, determining dynamics of the anomaly when the anomaly is detected in the diagnostic signal, continuous monitoring of a communication line by a limited anomaly counter, comparing the limited anomaly counter with an unlimited anomaly counter when the anomaly is detected inside the communication line and generating a differential signal on the basis thereof, and determining the thermal runaway on the basis of the determined frequency and the determined dynamics and the differential signal.
