Smart EV Charging-Discharging Management with Grid-Home-PV Interaction using V2X Charger

Electric Vehicle (EV) charging and discharging can be rapid and reliable when it is connected to a dedicated charging station. EV charging at home is always not possible due to other household electrical appliances and their demands. Smart EV charging and discharging can be achieved in solar PV-connected modern houses using a V2X (vehicle-to-everything)-enabled EV charger. This paper proposed a novel eight-mode control strategy to perform smart EV charging and discharging without affecting the operation of household appliances. At the same time, other operations such as V2G (vehicle-to-grid), V2H (vehicle-to-home), or V2L (vehicle to load) can be achieved using the V2X-enabled EV charger by applying the proposed control strategy. The simulation results obtained by MATLAB Simulink modeling show eight coordinated modes of operation depending on the availability and unavailability of grid supply, solar PV generation, and EV battery power based on its state of charge (SoC).
