A control method for a bi-directional DC/DC converter. A source terminal transmits electric energy to a destination terminal sequentially through a first rectifier module and a second rectifier module of the converter. The method includes obtaining a first voltage value output by the first rectifier module in a current control cycle, obtaining a second voltage value output by the second rectifier module in the current control cycle, calculating a theoretical voltage control quantity of the bi-directional DC/DC converter in the current control cycle based on a preset reference voltage value and the second voltage value, and setting an actual output voltage of the bi-directional DC/DC converter in a next control cycle based on the theoretical voltage control quantity and the first voltage value.

Bi-directional DC/DC converter, control method and apparatus thereof, and storage medium

The application provides a method, a charging-discharging device, a cloud server, a system and a medium for charging-discharging interaction, which belong to the fields of electric power technologies. The method for charging-discharging interaction includes: the charging-discharging device transmits a vehicle-to-grid V2G function confirmation message to a battery management system of a target vehicle; when no V2G function feedback message fed back by the battery management system is received within a preset period of time after transmitting the V2G function confirmation message, the charging-discharging device transmits a first indication message to a cloud server to indicate that the target vehicle is V2G-disabled; in response to a non-V2G charging instruction received from the cloud server, the charging-discharging device performs a non-V2G charging for the target vehicle. The availability of the charging-discharging device can be improved according to embodiments of the present application.
