“…One of the attractions to propose a CSI-based powertrain is the reliability increase of the inverter compared to using large dc-link capacitors. For example, the total calculated capacitance for the proposed configurations is much lower that the capacitance required in the Chevrolet Spark EV which is estimated around 850 𝜇F [19]. Meanwhile, the inductors used add to the size and weight of the powertrain.…”

“…Motor In CSI-based powertrains, the constant dc voltage supplied by the battery pack is converted to a controllable dc current via a dc-dc converter coupled with a choke inductor. Several previous works [4,19] reported that the simplest topology is a bidirectional chopper converter topology. The converter consists of two half bridges that can be implemented by combining only one switch and one diode in each leg.…”

In this paper, new powertrain configurations for heavy-duty electric vehicles (HDEV) are proposed based on current-source inverters (CSI) and asymmetrical six-phase motors. Voltage-source inverters (VSI) are widespread in many applications; however, VSI-based powertrains require a bulky bank of capacitors with a limited lifetime. Recently, powertrains based on the current-source inverter (CSI) are getting more attention to be a more reliable structure for EVs by replacing the dc-link capacitor with a choke inductor. To the authors' best knowledge, a six-phase CSI-based powertrain is not fully addressed yet. Since the six-phase CSI comprises two three-phase CSIs, multiple configurations can arise based on the connection between the two CSIs. In this context, the proposed powertrain configurations are based on parallel, cascaded, and standalone six-phase CSIs. The standalone topology is based on separating the two three-phase converters by supplying each converter with a dedicated dc-dc converter. All the proposed configurations are studied from the perspective of structure, modulation, and stresses/sizing. A case study highlights the differences and compares the three structures. The comparison is backed by experimental results, and a detailed discussion is provided for concluding a suggested selection of the best-suited topology.

Digital twin (DT) technology has been used in a wide range of applications, including electric vehicles. The DT platform provides a virtual representation or advanced simulation of a physical object in real-time. The implementation of DT on various aspects of EVs has recently transpired in different research studies. Generally, DT can emulate the actual vehicle on the road to predict/optimize its performance and improve vehicle safety. Additionally, DT can be used for the optimization of manufacturing processes, real-time condition monitoring (at all levels and in all powertrain components), energy management optimization, repurposing of the components, and even recycling processes. This paper presents an overview of different DT platforms that can be used in EV applications. A deductive comparison between model-based and data-driven DT was performed. EV main systems have been discussed regarding the usable DT platform. DT platforms used in the EV industry were addressed. Finally, the review showed the superiority of data-driven DTs over model-based DTs due to their ability to handle systems with high complexity.

“…SiC and GaN are quickly becoming commercially viable alternatives to Si as the material to construct future integrated iOBCs. Figure 33 depicts the current state of the art for integrated motor drives, with power densities in kW/L and kW/kg [96,[147][148][149][150][151][152][153]. The power density for commercial integrated motor drive ranges from a minimum of 2.4 kW/L (Nissan Leaf) in 2012 to a maximum of 15.3 kW/kg (Bosch Gen3) in 2019, whereas the majority of electric vehicles on the market in 2021 use Si semiconductors (such as the VW ID.3 with the new Infineon HybridPACK TM drive).…”

This article reviews the different topologies compatible with V2G feature and control approaches of integrated onboard charger (iOBC) systems for battery electric vehicles (BEVs). The integrated topologies are presented, analyzed, and compared in terms of component count, switching frequency, total harmonic distortion (THD), charging and traction efficiencies, controllability, reliability and multifunctionality. This paper also analyzes different control approaches for charging and traction modes. Moreover, the performance indices such as setting time, rise time, overshoot, etc., are summarized for charging and traction operations. Additionally, the feasibility of a Level 3 charging (AC fast charging with 400 Vac) of up to 44 kW iOBC is discussed in terms of converter efficiencies with different switching frequencies and switch technologies such as SiC and GaN. Finally, this paper explores the power density trends of different commercial integrated charging systems. The power density trend analysis could certainly help researchers and solution engineers in the automotive industry to select the suitable converter topology to achieve the projected power density.
