  • Abstract:
  • With advancements in battery technology, EVs offer an environmentally friendly alternative to traditional internal combustion engine vehicles. This project focuses on the design and implementation of a bidirectional power converter system for Electric Vehicle (EV) applications, integrating both a battery and a supercapacitor as energy storage devices. The bidirectional converter facilitates power flow in two directions: from the EV battery to the load and vice versa, allowing for efficient energy transfer and management. The proposed system comprises two main components: an EV battery and a supercapacitor, both connected to a bidirectional power converter. The EV battery serves as the primary energy source for the system, providing high-energy density storage for prolonged operation of the EV. The supercapacitor acts as a complementary energy storage device, offering high-power density storage for rapid energy transfer and regenerative braking applications. The bidirectional converter enables power flow between the EV battery, supercapacitor, and load in both directions. The proposed system utilizes a quadratic bidirectional converter topology, which offers improved efficiency, reduced switching losses, and enhanced control capabilities compared to traditional converter topologies. Through prototype development, and experimental validation, this project seeks to demonstrate the feasibility and effectiveness of the proposed bidirectional power converter system for EV applications.
