V2G Charging Interaction for Mixed V2G and Non-V2G Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
V2G-enabled charging-discharging devices cannot charge V2G-disabled vehicles, reducing their availability and utilization.
Innovation Solution
A method and system that includes a charging-discharging device and cloud server to transmit confirmation messages and instructions for non-V2G charging, allowing V2G-enabled devices to charge V2G-disabled vehicles by performing non-V2G charging operations when no V2G feedback is received within a preset time, and switching to V2G charging or discharging when the vehicle is confirmed V2G-enabled.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a V2G-enabled charging-discharging device is used, then V2G charging and discharging functionality is achieved, but V2G-disabled vehicles cannot be charged, reducing device availability
Solution Approach 1:
The charging-discharging device is designed to support multiple charging modes (V2G and non-V2G) to serve both V2G-enabled and V2G-disabled vehicles. The device universally handles different vehicle types by detecting V2G capability through confirmation messages and automatically switching between V2G charging mode for enabled vehicles and non-V2G charging mode for disabled vehicles, thereby achieving multi-functionality and improving device availability

AI summary
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.
