“…Therefore, although the input power fluctuates, it is possible to wait until the input and output power is stabilized by means of a timed interrupt. In this way, based on the sampled values of the stabilized input currents and voltages, the next phase shift angle adjustment can be calculated more accurately (Barman et al, 2023;Zhou et al, 2023). To increase the reliability of the control, the system compares Fuzzy algorithm optimal efficiency point system control process.…”

Introduction: The rapid development of electric vehicle technology in the field of renewable energy has brought significant challenges to wireless charging systems. The efficiency of these systems is crucial for improving availability and sustainability. The main focus of the research is to develop an intelligent charging strategy that utilizes fuzzy logic to optimize the efficiency of wireless charging systems for electric vehicles.Method: Introduce a model that combines fuzzy logic algorithm with automatic control system to improve the wireless charging process of electric vehicles. The model adopts dynamic tracking and adaptive control methods by analyzing the characteristics of static wireless charging systems. Utilizing primary phase shift control and secondary controllable rectifier regulation, combined with optimized fuzzy control algorithm.Result and discussion: The experimental results show that when the secondary coil is stable, the model maintains a stable duty cycle of about 75.6% and a stable current of 5A. It was observed that when the mutual inductance values were set to 10, 15, and 20 uH, the efficiency of the primary coil before applying control decreased with increasing resistance.Conclusion: The proposed system has shown great potential for application in real-world electric vehicle charging systems, demonstrating good applicability and feasibility in controlling the charging process and tracking the optimal efficiency point. The integration of fuzzy logic enhances the system’s ability to adapt to different operating conditions, which may lead to wider implementation and improved operational efficiency.

“…This improvement underscores the positive impact of integrating a capacitor bank in stabilizing and optimizing the battery's SOC across different load profiles. Figures 11,12,13, and 14 depict the State of Charge (SOC) of the system as it evolves over time while the proposed model is subjected to various load conditions. These figures provide a show how the SOC changes in response to different loads, both with and without the incorporation of a capacitor bank.…”

This experimental study investigates the performance of Lead Acid Battery driven Electric Rickshaws (E-Rickshaws) enhanced with a Capacitor Bank. With a growing demand for sustainable urban transportation solutions, E-Rickshaws have emerged as a promising option. However, challenges such as limited battery life and variable performance under different load conditions persist. In this research, we explore the application of a Capacitor Bank circuitry to mitigate these challenges. The study involves a series of performance tests conducted on E-Rickshaws equipped with the proposed hardware model. Key parameters, including charging current, charging time, and discharging current under varying load conditions, are rigorously analyzed. Our experimental results reveal substantial improvements in E-Rickshaw performance when compared to conventional Lead Acid Battery-driven models. Notably, reductions in starting current and minimized power fluctuations, especially under full load conditions, lead to a smoother and more efficient driving experience. Crucially, the extended battery life resulting from these hardware enhancements demonstrates the economic viability of the modified E-Rickshaw prototype. This research contributes valuable insights into the sustainable transformation of urban transportation, with implications for both performance optimization and economic feasibility in the E-Rickshaw industry.

The paper considered the theoretical information of generators for several power sources, schematic their solutions, and the main disadvantages and advantages. A generator for 4 batteries based on field-effect transistors with optical galvanic isolation and a clock generator built on the basis of the Atmega328 microcontroller, which is part of the Arduino Uno device, was studied. The result of the study was the confirmation of the existence of the "Tesla-switch" effect. A program code was developed for the alternate switching of six transistor switches of the optical decoupling. The structural diagram of the device was studied, and the influence of the generator frequency and the consumed power of the load on the output parameters of the device were determined. The considered idea of energy saving and environmental friendliness of power supply systems is relevant, in particular in cases of blackouts.
