Abstract –
Transportation electrification is happening at a rapid pace around the globe. As the electric vehicle technology recently evolved, the size of on-board storage units has increased, which require charging from an external energy source rapidly. By using renewable charging of electric vehicles is an attractive option to reduce the carbon footprint of an electric vehicle respectively. The intermittent nature of the renewable necessitates a storage unit to provide continuous power. With the system of solar generation, a strong and reliable power converter is deployed to interface these sources and storage units with the electric vehicle for charging. The reliable converter shall now have to operate to quench the charging requirements by sourcing power from solar generation and storage elements for the system. The converter also has capability to capture the generated solar power during the non-charging period and store it in the battery. All these functional requirements demand a unique, reliable and robust energy management strategy to utilize all available sources and storage units efficiently without compromising load requirements of the system.
In this project DSM-PI controller is used for Plug-in hybrid electric vehicle. This paper presents the methods of charging. The charging systems are simulated in MATLAB/SIMULINK. The problem of EV charger with DC output voltage settling & higher charging time required for battery charging is minimized with this paper. The expected charging has been simulated and presented in this project using MATLAB.
Key Words: —Electric vehicle battery charging, CC/CV control, RT-Lab simulation
