Abstract: 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.
