The development of high-confidence, real-time capable simulation models for virtual and hardware-in-the-loop testing offers new opportunities for the automotive industry in terms of virtual product development and production to reduce the time-to-market of the fuel cell electric vehicles (FCEVs) at lower costs. However, the challenge is the combination of the hybridization and electrifications in the FCEVs leading to significantly increased vehicle variants and increased system complexity. In this paper, a unified organization of digital models is applied with the objective to seamlessly integrate virtual and real testing as proposed in the PANDA project is presented. This tool is than applied to the postal delivery FCEV developed during the Mobypost project and its components at the vehicle level. The model can reflect that the method developed during the PANDA project is capable to describe the Mobypost vehicle with its multi-domains, including electric, magnetic, mechanical and chemical. Besides, by simulating a complex road environment, the proportion of power and energy between battery and fuel cell can also be provided for the optimization of the FCEVs parameters.

Through the formation control, the virtual connection of two tram can be effectively relieved, which can effectively alleviate the passenger demand during peak passenger flow, flexibly decompose when the passenger flow is low, which can effectively deal with tidal passenger flow. This paper presents a method for longitudinal tram platooning control of the Autonomous-rail Rapid Tram (ART) based on cooperative adaptive cruise control(cooperation ACC). The following tram in the CACC formation will sense the position of the leading tram and adjust the speed to avoid collision. In order to realize wireless information transmission between different vehicles through V2V, and transfer information including position, speed, acceleration or road intersection status to assist the tram formation decision and planning. On the other hand, in order to improve control performance, it is important to design a closed-loop controller that takes into account vehicle dynamics. In this article, we try to solve this problem by using the Model Predictive Control (MPC) algorithm, which can explicitly deal with the constraints imposed on the actuator or the acceleration response. Finally, through hardware-in-loop simulation verification, we verified that the developed platooning control has a faster response speed and higher comfort even in traffic jam scenarios.

This paper presents an analysis and design of a charging unit inside an electric vehicle extreme fast charging station. Due to the benefits that partial power processing achieves in terms of size reduction and efficiency improvement, it is decided to implement a partial power converter architecture. This type of architectures reduce the power to process by the converter but, they require an isolated topology. Therefore, a dual active bridge is selected for the study. Then, design wise, four different turns ratio values are selected and their performance results are compared in terms of processed power by the converter, semiconductors stress factor and energy loss. Finally, it is concluded that the turns ratio value is a key factor that must be correctly selected for optimizing the concerned comparison parameters.

In DC electrified railways pantograph electric arcs represent not only a disturbance, but the step change of the pantograph voltage affects power losses directly and indirectly. The available line voltage is reduced if the train is in traction condition, the arc itself is characterized by ohmic power losses, and the triggered oscillating transient responses are characterized by a net power loss. In addition, if arc occurs during braking the arc voltage suddenly increases the pantograph voltage and may interfere with the dissipative braking chopper, reducing the recovered energy. This work presents the model and analysis of these phenomena with experimental results for arcs measured on a 3 kV dc line in traction and braking conditions.

Today, electrified railway systems are involved in renewal processes, which address vehicles, wayside infrastructure and management of fleet of rolling stocks. Railway System Operators (RSOs) test how novel and innovative strategies impact of their own systems in order to reach energy efficiency targets. Due to the intrinsic interaction between the railway traction system and its primary grid, the feasibility of each innovative strategy has to be evaluated in terms of energy and power not only on the railway traction system, but also on its feeding grid. In the actual context forced by the constraint of Covit-19 virus, one of the more relevant strategies applied to urban railway systems is to operate the railway traction system with reduced values of headway. This strategy, which forces repetitive starts, in some cases contemporaneous, of rolling stocks, can produce severe voltage drops on the primary distribution grid. This paper proposes of examining the motion of a fleet of metro trains on a traction system fed by a MV distribution grid of reduced short circuit value. The numerical results point out how constraints imposed by the distribution grid at the Traction Power Substations can influence the control of moving the fleet of rolling stocks on the track.

In this paper, an innovative model structuration is proposed to describe scaled Permanent Magnet Synchronous Machines (PMSM) at system level. By using the Energetic Macroscopic Representation formalism (EMR), the equations of the scaling laws are reorganized. The restructuration consists of a reference PMSM model complemented with two electrical and mechanical power adaptation elements. These latter elements take care of the scaling effects, including the power losses. The methodology is applied to scale the power of a PMSM for an electric vehicle, by a factor of 2. According to the studied designs, an average efficiency from 83.7% to 87.1% is obtained during an urban driving cycle.

In this paper, a cooling scheme and the corresponding thermal design method is proposed for high power high frequency transformer, which is used in power electronic transformer device for railway traction applications. Particularly, to address the overheating problem resulting from dimensional restriction and electrical insulation in railway applications, the cooling scheme based on actively cooled system with R245fa refrigerants is further enhanced by 2-phase flow cooling. The mathematic model of transformer copper and iron loss is first introduced. Subsequently, the required cooling area of transformer core is quantitatively calculated using thermal network method and the total pressure loss and heat transfer in two-phase flow is determined accordingly. Finally, the proposed thermal design method and corresponding cooling scheme are verified through the experiment on a 5.5kHz 140kVA transformer.

This paper presents an operation cost analysis of a fuel cell/battery-based plug-in hybrid electric vehicle under different sizing configurations. Specifically, the size of major energy source (e.g. the fuel cell system) is kept constant while altering the battery capacity. Dynamic programming is then employed to extract the vehicle’s operation costs imposed by the consumption of hydrogen and electricity power. Afterwards, a numerical analysis of the impacts on fuel economy, fuel cell durability, battery energy utilization rate is conducted, so as to provide useful guidelines to facilitate the powertrain design and the development of corresponding energy management strategies.

When using single vector model predictive control, the direction of output voltage in each control cycle is limited. Therefore, there is pulsation and a quite large harmonic distortion in stator current. In this paper, a novel cascade multi-vector model predictive control strategy is proposed. Firstly, the model predictive controller is used to replace the traditional linear controller in the external speed loop, and a three-vector model predictive controller is designed in the internal current loop. The amplitude and direction of output voltage vector are adjustable which improves the performance of the current control. As multi-vector model predictive control will increase the switching frequency of the system, we construct a cost function with switching frequency constraints to solve this issue. Finally, the proposed control strategy is verified on the asynchronous motor experiment set that it can improve the current tracking performance and effectively reduce the switching frequency of the inverter while maintaining the speed loop with good dynamic and static performance.
