| Zusammenfassung: | A device includes a backup power supply configured to provide power to an external system upon loss of primary system power. The backup power provided by at least one capacitor. While the capacitor is available as a backup power supply to the external system, a transient elevation of the capacitor's stored potential is created above an upper predetermined operating potential of the capacitor. Measurements of a capacitor's output voltage are obtained during the transient elevation of the capacitor's stored potential. A capacitance of the capacitor is determined from the measurements. |
