Design and Development of Dual-Mode on-Board Battery Charger with Cuk Converter for Electric Vehicle | Chapter 2 | Theory and Applications of Engineering Research Vol. 9

 In recent days there has been growing interest in electric vehicle (EVs) technologies because of concerns about global warming, the energy crisis, and security. A combustion engine-based transportation mechanism uses only 30% of the fuel, and the rest of it goes as a loss. But in the case of electric motor motor-driven vehicles, the efficiency is more than 80%. However, charging configurations of EVs play a vital role in the development of automobile transformation. Hence, in the automobile industry increased demand for EVs requires an efficient and reliable system for recharging the battery. On-board charging and off-board charging are the two ways of charging schemes for EVs. This paper presents a topology that interfaces the two types of charging systems i.e. slow charging and fast charging as required by the user. TESLA S60 battery model is taken as an example for validation of the proposed topology in simulation. The Cuk converter is designed and implemented for charging the battery in two modes. The MATLAB/Simulink software is used to simulate and analyze the performance of the system. The prototype hardware model of the charger is developed and results are validated with simulation. The results show that the slow charging efficiency is 86% and the fast charging efficiency is more than 82%. In DC fast charging 22 V input is fed and for AC slow charging 230 V input is fed to get 12 V output. In the simulation, charging the battery in fast charging mode takes 5 hours and it takes 10 hours in slow charging mode for the same battery. The circuit charges the lead acid battery in 5 hours and 30 minutes in fast charging mode. In the case of slow charging mode, it charges in 11 hours 36 minutes.

Performance Evaluation of DC-DC Converters for Solar Photovoltaic-fed Switched Reluctance Motor Applications in Electric Vehicles | Chapter 4 | Contemporary Perspective on Science, Technology and Research Vol. 2

This member describes the performance of a Cosmic PV-powered switched disinclination motor accompanying low torque ripple in energetic vehicle applications. The prominent impression of solar energy in our nation’s strength requirements has become ruling in recent age. It is a boundless source of strength and the finest substitute for some other non-renewable beginnings in our country. Switched reluctance motors have enhance increasingly prevalent in the electric car subdivision due to their unbreakable looks, which include their enthusiastic ability, simple construction, lack of rotor windings, and depressed maintenance requirements. Nevertheless, because to its nonlinear face, SRM's large torque ripple is a restraint. This paper analyzes the performance of a exchanging reluctance engine with several DC-DC converters, and compares the judgments in terms of the motor's speed and turn ripple %. The switching time of the preacher is controlled by the MPPT controller, that uses incremental conveyance and the Integrator method. The converters presented in this place work are the Boost converter and the Cuk converter. These two types of converters are created in MATLAB software and their characteristics are analysed while furnishing the switched reluctance engine. . The DC-DC converter harvest is given to the input of capacity converter, which is irregular bridge converter. This converter drives the changed reluctance motor under changeable load conditions. By variable the duty cycle of the DC-DC preacher circuit the output service can be controlled. This in proper sequence controls the speed of the motor effectively. The verdicts of the simulation are used to resolve how well the suggested scheme works with the engine. From the results, it is evident that using this somewhat converter improves the speed and turn ripple performance of the cosmic PV powered switched disinclination motor. Hence, it is acceptable for electric vehicle uses, which require less revolution ripple and mechanical shakings.
