Abstract

The invention provides a power supply control device, a power supply control method, refrigeration equipment and a storage medium, and the power supply control device comprises a power supply circuit; a delay starting circuit the input end of which is connected with the output end of the power supply circuit, wherein the delay starting circuit comprises an energy storage device; a controller connected with the acquisition end of the delay starting circuit and the control end of the power supply circuit, wherein the controller is configured to obtain a discharge voltage value of the energy storage device according to a power-off signal corresponding to the power supply circuit, determine a first duration according to the discharge voltage value, and control the power supply circuit to restore power supply according to the first duration. The first duration after power failure is determined according to the discharge voltage value of the energy storage device, and the moment when the power supply circuit recovers power supply is controlled, so that starting failure caused by system imbalance when the system is quickly powered on after power failure can be effectively avoided, the failure rate of equipment applying the power supply control device is reduced, and the operation effect of the equipment is improved.
