1. An electrical system comprising:

  • a primary energy source for an electrical load;

    a rechargeable energy source for the electrical load;

    a first switch coupled between the primary energy source and the rechargeable energy source, wherein activation of the first switch facilitates charging of the rechargeable energy source with the primary energy source;

    a second switch coupled between the primary energy source and the electrical load;

    a third switch coupled between the rechargeable energy source and the electrical load; and

    a control unit to operate the second switch and the third switch such that by default the primary energy source is decoupled from the electrical load and the rechargeable energy source is coupled to the electrical load to provide operating power to the electrical load, and such that under a degraded performance condition associated with the rechargeable energy source the rechargeable energy source is decoupled from the electrical load and the primary energy source is coupled to the electrical load to provide operating power to the electrical load.
