After 1000 s, the simulation results are shown in Fig. 2. It can be seen from the figure that the voltage of supercapacitors is rising and gradually approaching during the charging process, and the charging rate is gradually decreasing. Finally, the voltage of each supercapacitor reaches the rated voltage of 2.7 V.
