The choice between AC and DC charging impacts V2G equipment design for electric vehicles.
Electric vehicle batteries require DC charging for V2G operations, while the electricity grid primarily uses AC transmission.
Conversion from AC to DC for V2G can occur in the vehicle through an onboard charger or at the V2G-enabled charging station.
Most electric cars designed for V2G have onboard chargers, necessitating additional power electronics for bidirectional charging capabilities.
The location of power electronics and control systems in V2G setups influences communication handling and regulations compliance for feeding electricity into the grid.
Ongoing development focuses on V2G solutions where costs for technology may be integrated into the vehicle or the V2G charging infrastructure.
Combined inverters are technically feasible for V2G applications, such as integrating household solar panels with V2G-compatible charging stations.
