Zusammenfassung: | An electronic device includes a subsystem, a plurality of energy storage elements coupled to the subsystem through one or more switches, and a charging and monitoring apparatus for concurrently charging the plurality of energy storage elements and monitoring operability of the energy storage elements. A first subset of the energy storage elements is coupled to a first node and a second subset of the energy storage elements is coupled to a second node of a bridge circuit. A power supply provides a DC charging voltage and an AC test voltage to both the first and second subsets of the energy storage elements. A monitoring circuit produces a predefined fault signal if a predefined electrical characteristic of the first subset of the energy storage elements differs from a same predefined electrical characteristic of the second subset of the energy storage elements by more than a predefined amount. |
