Digital Communication Control Application Involving Wireless Power Transmission for Charging Electric Vehicles

This paper presents a digital communication control application involving wireless power transmission for charging electric vehicles. In the development of electric vehicle (EV) charging systems, wireless charging plays a crucial role. This is due to the rise of self-driving automobiles and significant advancements in artificial intelligence. The majority of studies in this field use induction charging, while others use magnetic resonance. The proposed system is simulated and modeled in MATLAB/SIMULINK using state-space equations. The system architecture employs the inductor-capacitor-capacitor-capacitor (LCC-C) compensation topology. A 32-bit microcontroller ESP32 was used to facilitate communication between the transmitter and receiver. The receiver used a digital signal to start and stop charging, checked the energy level, and kept track of the EV tag for future ways to pay for energy. The project was designed and implemented to charge a lithium battery with a capacity of 55,000 mAh across a distance of 6 cm at 77.52% efficiency.
