Integrated Optimization of Dual Active Bridge Converter and Photovoltaic System for Electric Vehicles

The combination of Electric Vehicles (EVs) and Photovoltaic (PV) systems has high potential to increase the sustainability and energy efficiency. The work of interest in the current paper is on the optimization of the energy management system that consists of a Dual Active Bridge (DAB) converter and PV system to ensure real-time conversion and charging of the battery. The goal is to optimise energy efficiency by formulating a control approach wherein solar power generation, power conversion, and electricity storage are interactively optimised with the energy storage of the electric vehicles. Here, the mathematical model of the integrated system is presented, and the design of a real-time mechanism of control is proposed to manage optimal flows in the integrated system. Simulations in MATLAB are done to confirm the model performance in the proposed system's given realistic driving and solar generation conditions. The findings show that the optimized development between the PV system and the DAB converter results in improved energy conversion, battery charging capacity, and driving range augmentation. This article gives an idea about how renewable energy could be the way to go further in the process of transportation electrification, and how more efficient energy management systems could be put forward to support the use of energy in EVs.
