| Zusammenfassung: | A vehicle includes an electric power converter, a power source, a detection circuit, at least one processor, and at least one memory. The electric power converter filters voltage ripple generated by the electric power converter. The detection circuit determines an unfiltered measurement of the power source and a filtered measurement of the power source and generates a differential signal by comparing the unfiltered measurement and the filtered measurement. Said memory stores instructions executable by said processor. The instructions causes said processor to determine a state of health of the power source based at least in part on the differential signal. |
