“…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.

“…This model is capable of giving an accurate prediction of SOC, and state of discharge (SOD) of the battery. Equations of charging and discharging signals of LA, Ni-MH, and Li-ion based on ECM proposed by [16] are defined, respectively as LA and Ni-MH (1) (2) where (3) Li-ion (4) (5) where (6) where Vt is battery terminal voltage, E0 is battery constant voltage, Q is battery capacity, it is an actual battery charge, R is battery internal resistance, t is the actual battery current, K is polarization resistance, A is an exponential zone voltage, Vfull is fully charged voltage, and Vexp is exponential zone voltage. The parameters mentioned were obtained from the manufacturer datasheet except K, 3/Qexp and Vfull -Vexp should be measured from the discharge curve as in [16].…”

“…Field testing was done for three different cases for different types of batteries. Based on previous literature, ECM is not superior in terms of accuracy compared to electrochemical model because the errors made by using ECM can hit to 8% [29,3]. However, due to low in complexity makes ECM is capable to implement in low cost real-time monitoring system.…”

“…In order to maximize the battery run-time, as well as to maintain the power delivered, appropriate actions have to be taken. Therefore, a monitoring system based on battery performance estimation should be developed before effective prevention can be taken [3]. The battery signal, analysis methods, and parameters estimation have been studied according to the Institute of Electrical and Electronics Engineers (IEEE) Standard 1188-2005 standard.…”

This research presents the analysis of battery charging and discharging signals using spectrogram, and S-transform techniques. The analysed batteries are lead acid (LA), nickel-metal hydride (Ni-MH), and lithium-ion (Li-ion). From the equivalent circuit model (ECM) simulated using MATLAB, the constant charging and discharging signals are presented, jointly, in time-frequency representation (TFR). From the TFR, the battery signal characteristics are determined from the estimated parameters of instantaneous means square voltage (VRMS (t)), instantaneous direct current voltage (VDC (t)), and instantaneous alternating current voltage (VAC (t)). Hence, an equation for battery remaining capacity as a function of estimated parameter of VAC (t) using curve fitting tool is presented. In developing a real-time automated battery parameters estimation system, the best time-frequency distribution (TFD) is chosen in terms of accuracy of the battery parameters, computational complexity in signal processing, and memory size. The advantages in high accuracy for battery parameters estimation, and low in memory size requirement makes the S-transform technique is selected to be the best TFD. Then, field testing is conducted for different cases, and the results show that the average mean absolute percentage error (MAPE) calculated is around 4%.

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.
