“…Since these chargers are designed to run with alternating current, they do not meet the specific needs of this application, where a DC-DC conversion is required. These are rated with efficiencies varying between 82 and 96% depending on the technology that is used [100,101]. Therefore, the two main energy losses occur when the power is cached (15% loss) and transferred to the car (10% loss) resulting in a total efficiency of 76.5%.…”

Climate change is one of the major problems that people face in this century, with fossil fuel combustion engines being huge contributors. Currently, the battery powered electric vehicle is considered the predecessor, while hydrogen vehicles only have an insignificant market share. To evaluate if this is justified, different hydrogen power train technologies are analyzed and compared to the battery powered electric vehicle. Even though most research focuses on the hydrogen fuel cells, it is shown that, despite the lower efficiency, the often-neglected hydrogen combustion engine could be the right solution for transitioning away from fossil fuels. This is mainly due to the lower costs and possibility of the use of existing manufacturing infrastructure. To achieve a similar level of refueling comfort as with the battery powered electric vehicle, the economic and technological aspects of the local small-scale hydrogen production are being investigated. Due to the low efficiency and high prices for the required components, this domestically produced hydrogen cannot compete with hydrogen produced from fossil fuels on a larger scale.

“…In EVs there are two energy storage devices, the first one is the main energy system (MES) which has a high energy storage capability and the second one is the rechargeable energy storage system (RESS) which is a high power capability (Al, Van and Gualous, 2011). Direct current -Direct current (DC-DC) converter boost type is used in many applications as renewable energy and electrical vehicles.…”

In this research paper is a study of a technique that is used in the charging of electric vehicles. This technique, which is registered as a patent, is represented by adding electric generators to supply the electric vehicle with a portion of the energy which is needed for it. This technique has been studied in this research paper and a number of important things have to be considered when dealing with this topic, the most important things that have been studied are the effects on the speed of the electric vehicle, the regenerative braking and the amount of energy that can be provided through this innovation. This research paper includes design of DC-DC Boost converter with two loops PID controllers and design for a Field Oriented Control (FOC) of electric AC motors.

“…Moreover, the output voltage of batteries and SCs are unregulated and low; therefore, an HV DC-DC converter is required to increase the low unregulated electric source voltage to a highly regulated level by transitorily storing the source energy. This energy is stored either in electric field storage elements (capacitors) or in magnetic field storage elements (single inductor/multiport inductor/coupled inductor/interleaved inductor) using active switching components (IGBTs/ MOSFETs) and diodes [21,[44][45][46][47][48][49][50][51].…”

“…However, a small-sized, reliable, parameterized, lightweight, controllable, scalable, and efficient DC-DC converter has a higher demand in automotive industries. Some of these characteristics can be attained by using the interleaving technique of boost converter [49,[53][54][55][56]. Full-bridge boost converters can also be selected for BEVs and PHEVs if galvanic isolation is required between the source and the load [57][58][59].…”

This article reviews the design and evaluation of different DC-DC converter topologies for Battery Electric Vehicles (BEVs) and Plug-in Hybrid Electric Vehicles (PHEVs). The design and evaluation of these converter topologies are presented, analyzed and compared in terms of output power, component count, switching frequency, electromagnetic interference (EMI), losses, effectiveness, reliability and cost. This paper also evaluates the architecture, merits and demerits of converter topologies (AC-DC and DC-DC) for Fast Charging Stations (FCHARs). On the basis of this analysis, it has found that the Multidevice Interleaved DC-DC Bidirectional Converter (MDIBC) is the most suitable topology for high-power BEVs and PHEVs (> 10kW), thanks to its low input current ripples, low output voltage ripples, low electromagnetic interference, bidirectionality, high efficiency and high reliability. In contrast, for low-power electric vehicles (<10 kW), it is tough to recommend a single candidate that is the best in all possible aspects. However, the Sinusoidal Amplitude Converter, the Z-Source DC-DC converter and the boost DC-DC converter with resonant circuit are more suitable for low-power BEVs and PHEVs because of their soft switching, noise-free operation, low switching loss and high efficiency. Finally, this paper explores the opportunity of using wide band gap semiconductors (WBGSs) in DC-DC converters for BEVs, PHEVs and converters for FCHARs. Specifically, the future roadmap of research for WBGSs, modeling of emerging topologies and design techniques of the control system for BEV and PHEV powertrains are also presented in detail, which will certainly help researchers and solution engineers of automotive industries to select the suitable converter topology to achieve the growth of projected power density.
