1. A semiconductor circuit comprising:
a switching circuit;
a first electrical energy storage device that comprises a first battery, a first capacitor, and a first selection circuit configured to connect the switching circuit and at least one of the first battery or the first capacitor;
a second electrical energy storage device that comprises a second battery, a second capacitor, and a second selection circuit configured to connect the switching circuit and at least one of the second battery or the second capacitor;
a voltage measuring circuit configured to measure a first voltage of the first electrical energy storage device and a second voltage of the second electrical energy storage device; and
a controller configured to compare the first voltage and the second voltage and to generate a comparison result,
wherein the switching circuit is configured to connect the first electrical energy storage device and the second electrical energy storage device in an interconnection relationship based on the comparison result, and to provide to an output terminal an output,
wherein the first selection circuit is configured to connect the switching circuit without the first capacitor to the first battery when the first battery is not discharged, and the first selection circuit is configured to connect the switching circuit without the first battery to the first capacitor when the first battery is discharged,
wherein the second selection circuit is configured to connect the switching circuit without the second capacitor to the second battery when the second battery is not discharged, and the second selection circuit is configured to connect the switching circuit without the second battery to the second capacitor when the second battery is discharged, and
wherein the interconnection relationship of the first electrical energy storage device and the second electrical energy storage device is one of a serial interconnection or a parallel interconnection.
