E-rickshaws (or Electric-rickshaw) have sparked a great deal of interest as a green and sustainable transit option, as compared to traditional auto rickshaws that use fossil fuels. The primary component that affects E-rickshaw mobility over the course of its lifetime is its Energy Storage System (ESS). In contemporary E-rickshaws, lead-acid batteries are the most common form of ESS, hence it's essential to prolong their lifespan. From this perspective, we assess the potential for updating the traditional E-rickshaw's energy generation and storage systems for technological and financial gain by employing a solar PV panel on the rooftop. Battery Energy Storage System (BESS) is generally selected, but it reacts slowly to unpredictable transient events. Therefore, to construct a Hybrid Energy Storage System (HESS), a high-power density ESS like a supercapacitor (SCs) must be combined with a battery. In this paper, a combination of solar PV panel is installed over the E-rickshaw roof, along with the combination of both battery and SC as HESS. It is observed that HESS provides average power over extended periods of time and manages transient situations optimally. It normalizes the voltage and power at the DC link and regulates it according to the IEC 61000-3-2 standard. Finally, the MATLAB Simulink framework is used for performance analysis of the proposed system.

In developing countries, E-rickshaw is becoming popular and plays a vital role in initial and last-mile connectivity. The main reason for the wide acceptance of this mode of public transport is that it is economical as compared to a CNG auto, reduces air pollution, and provides better income opportunities. Over time, three major issues emerge related to the rise in fares, increased grid stress due to an increase in load demand for charging, and unsystematic disposal of lead-acid batteries. Presently, architectures for the charging station are available in the market but they are based on-grid supply which results in additional stress on the existing grid. In this proposed work a dedicated real-time socio-economic case study has been done to explore issues at the ground level to develop a photovoltaic (PV) based off-grid battery charging & swapping station (BCSS) and define a new category of E-rickshaw. The BCSS is proposed keeping objectives in mind to increase the return on investment (ROI) of both E-rickshaw owners by defining new a category & charging stations with fast recovery on the initial investments.
There has been a significant increase in the use of renewable energy solutions such as Photovoltaic (PV) power plant projects to decrease the dependency on fossil fuels while still meeting the global energy demands. H...

The designing and modeling of renewable based Electric Vehicle Charging Station (EVCS), using Solar Photovoltaics (SPV), SEPIC converter along with Maximum Power Point Tracking (MPPT) control, a BUCK converter as Voltage Regulation (VR) mechanism and Constant Current (CC) and Constant Voltage (CV) battery control for Li-ion battery charging which here is assumed as EV battery is proposed. A detailed modeling of the system is done in MATLAB/SIMULINK. The increase in Electric Vehicle (EV) has led to increasing demand of EVCS. The design proposed here is for off grid standalone charging station with renewable source integration enhancing green and clean energy source for sustainable transportation. Standalone systems are required to power the charging stations where grid feasibility is not available like in rural areas. SEPIC along with MPPT algorithm is used to dynamically optimize operating points of SPV to achieve maximum energy under different environmental conditions. In this paper a sustainable power generation system for Electric Vehicle Charging Station (EVCS) is proposed. The adoption of FLC for CC-CV control is advantageous over PID control in dealing with nonlinearities and adapting real time conditions parameters in changing environment. The performance and feasibility of system is demonstrated via results of simulations in SIMULINK. The dynamic responses of FLC based CC-CV charging system and overall system is observed.

Due to lack of electricity, many communities in India employ fossil fuel-based water pumping systems for irrigation. Due to the dangerous greenhouse gases they release, fossil fuels seriously impact the ecosystem. In this study, a solar energy-based automated water pumping system is suggested that can be deployed in many villages. The automatic system only activates the water pumps when the soil moisture content falls below a specific level, as measured by the moisture sensors positioned across the fields. This paper describes the advanced development on controlling and operating solar water pumps using the internet and messaging control for turning ON and OFF. The main aim of this type of system is to make it user-friendly, reliable, easy to handle and more efficient so that people can use it easily without facing any difficulty. This system saves electricity, produces a pollution- free environment, and also reduces the running cost. In this research work, modelling of an MPPT based solar water pump system is done in proteus software, which focuses on controlling the MPPT output power and switching of the solar pump. The Hill Climbing (HC) algorithm based MPPT is designed, which is coupled with a boost converter for obtaining high solar energy output. The overall output of the system is controlled by the Arduino programming based controller for automatic switching of solar pump.
