The modern trends in converting a gasoline-powered vehicle (Diesel, Petrol, or CNG) into an electric vehicle requires an appropriate redesign in the placement of new electrical components. These new trends of approaches are often applied to vehicles that are manufactured for the sole purpose of operating a fully electric vehicle without any gasoline components. However, in the case of retrofitting a gasoline-powered vehicle into a battery-powered electric vehicle (EV), different approaches are used in an already running vehicle that can be converted into a fully functioning Electric Vehicle. This results in better recycling, environment-friendly usage of old vehicles, and a massive improvement in air pollution levels. A minimum amount of maintenance while owning an Electric Vehicle is a key factor where the automobile industry gains attention for buyers or customers. The conversion of traditional or conventional vehicles into fully functioning Electric Vehicles has gained preference in recent years. However, the components used in an Electric vehicle are to be discussed to fully assess the working of an EV in the process of this conversion. In this paper, we shall focus particularly on the implementation of such conversions and controlling of the electric vehicle through different types of Electric Vehicle Control. The functions of each component in an Electric Vehicle Controller or just a controller in general, show different approaches to communicating with each other to achieve an efficient range and performance of the particular electric vehicle. The relations between these components inside of an EV controller can be studied by their energy flow, circuitry, and their functions. Control Area Network (CAN) is also considered as a topology to determine the aforementioned working of each component. Fault diagnosis, charging status, and battery capacity status are some of the many factors that are applicable after installing a controller within the Electric Vehicle.

This paper presents a review on the recent research and technical progress of electric motor systems and electric powertrains for new energy vehicles. Through the analysis and comparison of direct current motor, induction motor, and synchronous motor, it is found that permanent magnet synchronous motor has better overall performance; by comparison with converters with Si-based IGBTs, it is found converters with SiC MOSFETs show significantly higher efficiency and increase driving mileage per charge. In addition, the pros and cons of different control strategies and algorithms are demonstrated. Next, by comparing series, parallel, and power split hybrid powertrains, the series–parallel compound hybrid powertrains are found to provide better fuel economy. Different electric powertrains, hybrid powertrains, and range-extended electric systems are also detailed, and their advantages and disadvantages are described. Finally, the technology roadmap over the next 15 years is proposed regarding traction motor, power electronic converter and electric powertrain as well as the key materials and components at each time frame.

“…To develop the efficiency map of the motor, the finite element method (FEM) was used to obtain the inductance L d and L q on the dq-axis, as well as the magnetic flux ψ a for a permanent magnet. Based on the FEM results, the information needed for the efficiency map of the motor is derived through the following Equation of torque (10) and Equations of voltage ( 11)-( 13) [13], by using the equivalent circuit (Figure 6) on the dq-axis of the motor [14]:…”

In a battery-electric vehicle, a representative electric vehicle, there is a growing demand for performance and one-charge mileage improvement. As an alternative to such improvements, the capacity of the battery has been increased; however, due to the corresponding increase in the weight of the battery and the limited space in the vehicle, increasing the capacity of the battery also has limitations. Therefore, researches are being actively conducted to improve system operation efficiency to overcome such limitations. This paper proposes a distributing method of the driving forces to a battery-powered electric shuttle bus for last-mile mobility equipped with the decentralized driving system while taking into account voltage changes of the input terminals due to changes in the battery charge. The system operation efficiency changes were compared and evaluated by performing energy consumption analysis using ‘Manhattan Bus Driving Cycle’ at low voltage condition (SOC 20%). Various analyzes were performed and compared, such as the uniform distribution method of driving forces of the front and rear wheels (Uniform), the optimization method without considering the input terminal voltage change (Vnorm = 90 V), and the optimization method considering the input terminal voltage change (Vdclink). As a result, it shows that the proposed algorithm can improve 6.0% compared to the conventional uniform driving force distribution method (Uniform). Moreover, it shows that the real-time optimization method without considering the input voltage change (Vnorm = 90 V) can improve 5.3% compared to the uniform distribution method. The proposed method can obtain an additional 0.7% increase in total cost compared to the existing optimization method, which shows that the vehicle system has cost-effectiveness by reducing the battery capacity required to achieve the same mileage.
