1. An energy-recovery generation system for a handling and carrying electric vehicle, comprising:

  • a hoisting cylinder having an output pipeline provided with a pressure sensor unit and a directional valve;

    the directional valve (2) is under the control of the pressure sensor unit (1);

    a first outlet of the directional valve is connected to a tank via a multi-way valve with an operating handle;

    pressure oil is configured to flow out from a second outlet of the directional valve, pass through a pump having an oil suction port capable of bearing pressure or through a motor, and then pass through the multi-way valve, to finally flow back to the tank;

    the pump or the motor drives an electric motor to output electric energy; and

    an electric energy output end of the electric motor is connected to an energy storage device through a converter.
