The invention discloses a super-capacitor-based elevator regenerated electric energy storage and recycling system which is connected in parallel to a direct current bus of a variable frequency driving system of an elevator and comprises a control unit and a super-capacitor energy storage unit, and the super-capacitor energy storage unit is connected with the direct current bus of a frequency converter through a charging and discharging loop; from the frequency converter side to the super capacitor energy storage unit, an isolation protection switch, a switching contactor, a super capacitor discharging switch and a pre-charging unit are sequentially arranged on the charging and discharging loop. The switching contactor, the pre-charging unit and the super capacitor energy storage unit are connected with the control unit; the control unit is connected with a frequency converter direct current bus and a frequency converter three-phase output line; the super capacitor energy storage unit is connected in parallel with the DC/DC step-down power supply module and the back-up power supply output isolation switch. A frequency converter direct current bus is directly hung through the super-capacitor energy storage unit, regenerative electric energy generated in the elevator running process is stored and recycled on site, and meanwhile, a backup power source support is provided for an elevator five-party intercom system and a power-off releveling layer.
