“…However, each battery technology has a separate way in which it must be treated. Majorly, the mathematical modeling of a battery system in a hybrid system depends on the battery state of charge (SOC), the depth of discharge (DOD), and the state of health (SOH) [36,37]. The SOC is the cumulative sum of charge or discharge transfers of the battery daily.…”

Over the years, sustainability and impact on the environment, as well as operation expenditure, have been major concerns in the deployment of mobile cellular base stations (BSs) worldwide. This is because mobile cellular BSs are known to consume a high percentage of power within the mobile cellular network. Such energy consumption contributes to the emission of greenhouse gases (GHGs) through the use of conventional diesel generating set (gen-set). As a result, mobile cellular operators are faced with the dilemma of minimizing the power consumption, GHG emissions, and operation cost, while improving the quality of service (QoS) of the networks. In attempting to find a solution, this study presents the feasibility and simulation of a solar photovoltaic (PV)/battery hybrid power system (HPS), as a predominant source of power for a specific mobile cellular BS site situated in the Soshanguve area of the city of Pretoria, South Africa. It also presents the technical development and shows the environmental advantage and cost benefits of using a solar PV/battery HPS to power a BS site with a 24 h daily load of 241.10 kWh/d and peak load of 20.31 kW as compared to using the HPS with a solar PV/diesel gen-set/battery. The solar resource pattern for the city of Pretoria was collected from the National Aeronautics and Space Administration and was modeled statistically. The statistical modeling done using solar radiation resource exposure characteristic patterns of Pretoria, South Africa revealed an average annual daily solar radiation of 5.4645 Wh/m 2 /d and a 0.605 clearness index. The simulation and the design were done using Hybrid Optimization Model for Electric Renewables (HOMER) and Matlab/Simulink software. The simulation finding showed that the HPS of the solar PV/battery combination has about a 59.62% saving in the net present cost (NPC) and levelized cost of energy (LCOE) and an 80.87% saving in operating cost as against conventional BSs powered with a gen-set/battery.

“…The Li-Ion battery with a capacity of 24V and 16Ah is the primary source of power that is connected to the voltage regulator. The voltage regulator is responsible for regulating the input DC voltage of 24V from the battery to 5V, which is required for the proper functioning of the throttle and gate driver circuits [22][23][24][25].…”

The dwindling supply of fossil fuels has created a shortage, while the discharge of CO2 emissions from internal combustion engines poses a serious threat to the environment through air pollution. Hence, electric vehicles (EVs) play a vital role in the automotive sector by decreasing CO2 emissions and reducing the usage of fossil fuels. The performance of EVs is also comparable to that of internal combustion engines used in automobiles. The faithful operation of an EV relies on three main parts: the battery, controller, and motor. This proposed research article emphasizes the design, implementation, and testing of a low-cost EV controller that operates at a lower frequency than other conventional high-frequency controllers. A PMDC motor is used as a load to rotate the wheels, and a Lithium-Ion battery powers the electric vehicle. The controller, which is the major part of the vehicle, is used to control the PMDC motor. The controller controls the output voltage, and the converter is controlled by the controller. Compared to conventional vehicles or transport, electric vehicles are more efficient, and this E-vehicle's load capability will be increased. The ripple of the output voltage from the converter will be reduced by adding capacitors.

In this paper, an AC to DC rectifier circuit has been discussed and the simulation results are provided. This converter is very useful for the upcoming development of the electric vehicles charging technology. For producing steady DC from a rectified AC supply requires a smoothing circuit or filter. The main purpose of the filter circuit is to remove the ripple or ac components from the output of the diode circuit. So, to make the output DC pure, the filter circuit is used. The filter circuit may be inductive (built with only inductors in series) or capacitive (built with only capacitors in parallel) or Inductive-Capacitive (built with both inductors and capacitors). A voltage regulator which is used to maintain the constant output DC voltage. Design of the controller is detailed for reference. The converter will operate in continuous conduction mode (CCM). Finally, some selected experimental results are presented to verify the proposed theory.
