The effectiveness of electric vehicles as a form of transportation has been studied in light of the expanding environmental concerns and ever-tighter emission regulations. Electric car battery charger topologies are crucial for boosting the use of electric automobiles (EVs). The study’s onboard plug-in battery charger for electric cars supports SEPIC, resonant inverter, or LLC topology and is suitable for nearby electric e-bikes with a 48V battery pack. In order to obtain the least amount of grid current ripple, an adaptive DC link voltage technique is also recommended for achieving the appropriate DC link voltage under all voltage conditions. The charger also employs a voltage synchronisation strategy to ensure a seamless mode transition between the grid-connected and freestanding modes. MATLAB/Simulink is used to simulate and validate the on-board charger.
Key words: Electric Vehicle / Lithium-ion Battery / Battery charger / SEPIC converter / LLC resonant converter
