This paper presents the control and design of a stand-alone photovoltaic (PV) system with a battery bank for an electric vehicle (EV) battery charging. It also describes the necessary requirements and power electronic converters design for the EV battery charging station. The design of a bidirectional converter to allow for bidirectional power flow control to regulate the charging and discharging of the battery bank is presented. The PV system connected to the battery bank system is used to enhance the power output of renewable energy sources, regulate electrical power to effectively charge batteries, draw maximum power from solar panels, and provide a high-quality DC output for electric vehicle charging. The PV is the primary power source of the system, and a battery bank is used as a backup storage system. A comparison between the performance both of lithium-ion batteries and lead-acid batteries based on using it as a backup storage system for the off-grid PV system is presented. The proposed system has been designed and simulated in the MATLAB-Simulink environment. The effective performance of the proposed station for EV battery charging is achieved through the simulation results. A proposed charging station cost estimation is performed to present a powerful index of the proposed charging station's effectiveness.

The energy sector of today’s Rwanda has made a remarkable growth to some extent in recent years. Although Rwanda has natural energy resources (e.g., hydro, solar, and methane gas, etc.), the country currently has an installed electricity generation capacity of only 226.7 MW from its 45 power plants for a population of about 13 million in 2021. The current national rate of electrification in Rwanda is estimated to 54.5% (i.e.; 39.7% grid-connected and 14.8% off-grid connected systems). This clearly demonstrates that having access to electricity is still a challenge to numerous people not to mention some blackout-related problems. With the ambition of having electricity for all, concentrated solar power (CSP) and photovoltaic (PV) systems are regarded as solutions to the lack of electricity. The production of CSP has still not been seriously considered in Rwanda, even though the technology has attracted significant global attention. Heavy usage of conventional power has led to the depletion of fossil fuels. At the same time, it has highlighted its unfriendly relationship with the environment because of carbon dioxide (CO2) emission, which is a major cause of global warming. Solar power is another source of electricity that has the potential to generate electricity in Rwanda. Firstly, this paper summarizes the present status of CSP and PV systems in Rwanda. Secondly, we conducted a technoeconomic analysis for CSP and PV systems by considering their strengths, weaknesses, opportunities, and threats (SWOT). The input data of the SWOT analysis were obtained from relevant shareholders from the government, power producers, minigrid, off-grid, and private companies in Rwanda. Lastly, the technical and economical feasibilities of CSP and PV microgrid systems in off-grid areas of Rwanda were conducted using the system advisor model (SAM). The simulation results indicate that the off-grid PV microgrid system for the rural community is the most cost-effective because of its low net present cost (NPC). According to the past literature, the outcomes of this paper through the SWOT analyses and the results obtained from the SAM model, both the CSP and PV systems could undoubtedly play a vital role in Rwanda’s rural electrification. In fact, PV systems are strongly recommended in Rwanda because they are rapid and cost-effective ways to provide utility-scale electricity for off-grid modern energy services to the millions of people who lack electricity access.
