Abstract - Electric Vehicles (EVs) are going to be the future of eco-friendly transport and will soon reduce the toxic gas emissions dramatically besides cutting down the reliance on fossil fuels. One issue that EV technology faces is the improper use and management of several energy sources— batteries and renewables like solar—effectively. The present paper suggests a new kind of Single Inductor Multi-Port (SIMP) DC-DC converter that has been designed solely for electric vehicle applications. The converter allows for the interconnection of various DC power sources with high efficiency, and flexibility, and the use of one inductor at a time, which greatly lowers the power conversion system's overall size, weight, and cost. The proposed system is a dual input SIMP converter linked to a solar panel and a battery, which together supply power to the major traction drive (through an inverter and electric motor) and auxiliary loads. The topology designer of the converter has devised programs for its various degrees of operation including: solar-to-load, battery to-load, and solar-to-battery charging, thus guaranteeing the best power distribution and the least energy loss. The common inductor is time-multiplexed to facilitate the energy transfer among the different port’s openings, thus allowing dynamic source switching and energy sharing without having to resort to multiple big inductors or transformers.

Simulation studies performed in MATLAB/Simulink are the proof of the theoretical design and they also show the characteristics of good voltage regulation, high conversion efficiency, and stability during various input and load conditions. The converter is capable of operating efficiently under light as well as heavy load conditions. Hence, it is a perfect candidate for real-time ev application where power demand varies. In addition, the less number of components means there is less electromagnetic interference (EMI), more power density, and better cooling. The extruded SIMP converter is a paramount in the area of compact and smart power management systems for electric vehicles.
