This paper presents a straightforward power management algorithm that supervises the contribution of more than one energy source for charging a vehicle, even if the car is in motion. The system is composed of a wireless charging system, photovoltaic (PV) generator, fuel cell (FC), and a battery system. It also contains a group of power converters associated with each energy resource to make the necessary adaptation between the input and output electrical signals. The boost converter relates to the PV/FC, and the boost–buck converter is connected with the battery pack. In this work, the wireless charging, FC, and PV systems are connected in parallel via a DC/DC converter for feeding the battery bank when the given energy is in excess. Therefore, for each of these elements, the mathematical model is formulated, then the corresponding power management loop is built, which presents the significant contribution of this paper. The efficient power management methodology proposed in this work was verified on Matlab/Simulink platforms. The battery state of charge and the hydrogen consumption obtained results were compared to show the effectiveness of this multi-source system.
Wireless power transfer provides a new technology to charge electric vehicles (EVs) without physical contact. This system has to partially resolve the autonomy problem for EVs and buses. The majority of researchers were exposed to two categories of this technique: stationary wireless charging (SWC) and dynamic wireless charging (DWC) systems. Actually, the wireless recharge method is a recent solution that eliminates the problem of waiting time in recharge stations. However, the problem is always related to the vehicle status: if it is in motion and if it is in high-speed running mode. In this context, this paper defines and examines the mathematical model of the DWC system and explains its function in relation to several parameters related to the vehicle situation. This study explores the mathematical model and identifies the best conditions for using the recharge method when the vehicle is in motion. The analysis study was elaborated using MATLAB/Simulink software, and the obtained results showed the variation of the state of charge, depending on the vehicle speed.
