1. An uninterruptible energy storage system comprising:
a first energy storage unit with a positive and negative terminal,
a second energy storage unit with a positive and negative terminal,
a DC load,
a DC power source,
an output series circuit configuration wherein the first energy storage unit and the second energy storage unit are connected in series to the output series circuit configuration, to supply power to the DC load,
a first input parallel circuit configuration wherein the DC power source is connected to the first energy storage unit, and
a second input parallel circuit configuration wherein the DC power source is connected to the second energy storage unit,
a control unit that regulates a cycle having a duration comprising a first phase and a second phase,
wherein during the first phase, the DC power source connects to the first input parallel circuit configuration,
wherein during the second phase, the DC power source connects to the second parallel circuit configuration, and
wherein the control unit is capable of simultaneously activation and selected from the group consisting of at least one DPDT switch, at least one programmable mechanical switch, and at least one electronic device selected from the group consisting of at least one transistor, at least one printed circuit board, at least one integrated circuit chip, and at least one microcontroller.
