Abstract: Introduction was made to the working principle of supercapacitors in stand-alone photovoltaic system, as well as their advantages and disadvantages. This paper gave four kinds of supercapacitors equivalent electric circuits, such as three-branch circuit, transmission line, RC circuit in series and improved RC circuit in series and studied a variety of supercapacitors charging modes, analyzing the efficiency of supercapacitors constant voltage, constant current and constant power charging modes. Experimental research shows that the three kinds of charging modes have their own advantages and disadvantages. Under the precondition of ensuring the charging efficiency, the constant power charging mode can control charging time better, so it is more suitable for supercapacitors charging.
Key words: supercapacitor; energy storage element; charging mode
