Super capacitor circuit, charging and discharging method and power concentrator super capacitor system

The invention provides a super-capacitor circuit, a charging and discharging method and a power concentrator super-capacitor system, and the super-capacitor circuit comprises a plurality of super-capacitors and a plurality of switch groups. Each super capacitor is correspondingly connected with one switch group; every two adjacent super capacitors are connected through a switch group. The switch group is configured to control the plurality of super capacitors to be connected in series or in parallel by switching off or switching on each switch in the switch group; the super-capacitor circuit discharges when the multiple super-capacitors are connected in series, and the super-capacitor circuit charges when the multiple super-capacitors are connected in parallel. According to the invention, the connection mode of the corresponding super-capacitors is controlled by controlling the on or off of each switch in the switch group, so that the super-capacitors are charged during parallel connection and discharged duri
