1. A method for charging-discharging interaction, comprising:
transmitting, by a charging-discharging device, a vehicle-to-grid (V2G) function confirmation message to a battery management system of a target vehicle;
transmitting, by the charging-discharging device, a first indication message to a cloud server to indicate that the target vehicle is V2G-disabled, 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;
performing, by the charging-discharging device, a non-V2G charging for the target vehicle, in response to a non-V2G charging instruction received from the cloud server,
wherein the non-V2G charging instruction is transmitted by the cloud server in response to the first indication message or a non-V2G charging mode selection instruction from a terminal device communicatively connected with the cloud server.
