The invention relates to a clean energy charging discharging circuit and a control method thereof, which comprises a solar energy conversion module and a wind energy conversion module. The solar energy conversion module and the wind energy conversion module are respectively connected with a stored electrical energy module. Charging current sampling modules are arranged between the wind energy conversion module and the stored electrical energy module, as well as between the wind energy conversion module and the stored electric energy module. The stored electrical energy module and the charging current sampling module are respectively connected with an intelligent charge discharge coordinated control module. The intelligent charge discharge coordinated control module is connected with a lighting control system. The stored electrical energy module is connected with the lighting control system, and an external circuit is connected with the intelligent charge discharge coordinated control module. The clean energy charging discharging circuit and the control method thereof has the advantages that in the charge and discharge control system, through the introduction of the intelligent charge and discharge coordinated control module, the charging current sampling control is realized, which can be used to evaluate the budget of a battery power, a discharge coefficient is output then, the output lumen control of the lighting control system is achieved.
