a power supply unit which could change its voltage from 0 V to 5 V DC and its current to 0 A to 2 A. I read this to mean a variable power supply. The input might come from a battery, but then you need to convert the voltage somehow. You might do this with an adjustable linear regulator, or a switch mode power supply.
Implementing a backup power supply circuit can be a significant undertaking for the inexperienced engineer. The key complexity is that commercial supercapacitors are rated for around 2.7 volts, so to supply a typical 5-volt power rail, two supercapacitors must be used in series (Figure 4).
The dual power supply electric vehicle is driven by the batteries as primary energy source and the super-capacitors as the assistant power source. Discarding of voltage variation, for dual power supply system, the relationship of battery, BDC with super-capacitor, and the load in power or in current can be simplified to as shown in Fig. 4. In ...

Modular supercapacitor packages can supply significant amounts of backup energy. The Eaton XLR-16R2507B-R (Figure 3, right) has a capacitance of 500 F and operates with a maximum voltage of 16.2 V. The module has an ESR of 1.7 milliohms (mΩ) and can supply a peak power of 38.6 kilowatts (kW).
In the case of a black start operation in a microgrid, the amount of power to be connected should consider the capacity of energy storage. In such a case, supercapacitor-battery hybrid energy storage can handle the voltage and frequency stability by supplying the auxiliary power from the battery and transient power from the supercapacitor [28].
