The evaluation of differences between the electric vehicle (EV) charging architectures is a crucial point in choosing between AC and DC charging solutions, given the diverse requirements of various use cases (e.g. workplace charging). This research paper presents a model and simulation of EV charging architectures, including the grid, photovoltaic (PV), and battery energy storage system (BESS), for varied charging scenarios to investigate the power conversion efficiency of AC and DC charging at 11 kW and 22 kW power levels. The EV chargers are used in different architectures to simulate charging scenarios using grid, PV, and BESS. The simulation parameters incorporate a typical office consumption profile and multiple charging points for both power levels. The simulation results demonstrate that DC charging is superior in both PV and BESS scenarios, with PV charging being more efficient. The daily losses for different charging architectures were extrapolated to weekly and annual losses to elucidate the long-term benefits of PV DC charging.
考虑到各种用例(例如工作场所充电)的不同要求,评估电动汽车(EV)充电架构之间的差异是选择交流和直流充电解决方案的关键。本文提出了电动汽车充电架构的模型和仿真,包括电网、光伏(PV)和电池储能系统(BESS),用于不同的充电场景,以研究交流和直流充电在11千瓦和22千瓦功率水平下的功率转换效率。电动汽车充电器用于不同的架构中,以模拟使用电网,PV和BESS的充电场景。仿真参数包含典型的办公室消耗配置文件和两个功率水平的多个充电点。仿真结果表明,直流充电在光伏和BESS两种情况下均优于直流充电,且光伏充电效率更高。不同充电架构的日损失被外推到每周和每年的损失,以阐明光伏直流充电的长期效益。

Energy consumed by trams is studied in many papers, with a wide diversity of approaches regarding how to model and solve this problem. A novel approach to modeling the power consumption of trams is presented in this paper. To identify the unknown parameters influencing the rolling resistance force acting on the tram, it is necessary to measure the power consumption and speed of a single tram (or multiple trams if there are different car types in operation). The developed model of the tram is calibrated with data from the Sarajevo tram system. Simulation results are compared with measurements and a good correlation was obtained. The power consumption model of the tram with identified parameters can be further used to develop a framework for the power consumption estimation of the traction substation.
有轨电车的能源消耗在许多论文中都有研究,关于如何建模和解决这一问题的方法多种多样。本文提出了一种新的有轨电车功耗建模方法。为了识别影响作用在有轨电车上的滚动阻力的未知参数,有必要测量单辆有轨电车(或多辆有轨电车,如果有不同的车种在运行)的功耗和速度。开发的有轨电车模型是用萨拉热窝有轨电车系统的数据校准的。仿真结果与实测结果进行了比较,得到了较好的相关性。利用已识别参数的有轨电车功耗模型,可进一步建立牵引变电所功耗估算框架。

The increased switching frequency offered by Silicon Carbide (SiC) based Multi-chip Power Modules may allow designers to reduce the size and weight of passive elements while still meeting converter specifications. For the 3-phase Voltage Source Rectifier (VSR), as switching frequency increases, the DC-link capacitor may be reduce while maintaining the same voltage ripple. However, an often overlooked part in sizing the DC-link capacitance is the converter's stability. The use of conventional control methods, such PI-based controls, may lead to larger DC-link capacitance to prevent instability, minimizing the value proposition of Wide Band Gap-based power conversion. Applications like electrified shipboard or more electrical aircraft can be extremely sensitive to increases in size/weight due to limited space and/or significant annualized fuel costs. To this end, this paper explores, through simulation, a nonlinear control method based on Lyapunov's direct method published 25 years ago to minimize DC-link capacitance of an SiC-based VSR.
基于碳化硅(SiC)的多芯片电源模块提供的更高开关频率可以使设计人员在满足转换器规格的同时减小无源元件的尺寸和重量。对于三相电压源整流器(VSR),随着开关频率的增加,可以在保持相同电压纹波的情况下减小直流链路电容。然而,在确定直流链路电容的尺寸时,一个经常被忽视的部分是变换器的稳定性。使用传统的控制方法,如基于pi的控制,可能会导致更大的直流链路电容,以防止不稳定,使基于宽带隙的功率转换的价值主张最小化。由于空间有限和/或巨大的年化燃料成本,电气化船舶或更多电动飞机等应用对尺寸/重量的增加非常敏感。为此,本文通过仿真,探索了一种基于25年前发表的Lyapunov直接法的非线性控制方法,以最小化基于sic的VSR的直流链路电容。

In recent years, fuel cells have been considered more and more attractive devices for generating electric power from green fuels. On the other hand, their applications are still limited by technical issues, which are mainly related to hydrogen availability and storage. In the case of an onboard application for ships, hydrogen use is subjected to further restrictions and proper regulation is still under development. In this context, high-temperature fuel cells represent an interesting solution, since they can be equipped with reformers that convert liquid fuels into hydrogen, overcoming all the difficulties associated with its presence onboard. In this paper, a 5-kW high-temperature fuel cell system powered by methanol is analyzed for its possible application as a main propulsion power source for a small boat. An energy storage system is also considered in order to improve the overall system response. Preliminary results of fuel cell parameters at various operating points and during different working conditions have been obtained by means of a laboratory set-up. The obtained results have been also used to evaluate a preliminary system design.
近年来,燃料电池被认为是越来越有吸引力的绿色能源发电设备。另一方面,它们的应用仍然受到技术问题的限制,这些问题主要与氢的可用性和储存有关。在船上应用的情况下,氢的使用受到进一步的限制,适当的法规仍在制定中。在这种情况下,高温燃料电池代表了一种有趣的解决方案,因为它们可以配备转化炉,将液体燃料转化为氢,克服了与氢相关的所有困难。本文分析了一种以甲醇为动力的5kw高温燃料电池系统作为小船主推进电源的可能性。为了提高整个系统的响应能力,还考虑了储能系统。通过实验室装置,获得了不同工况下燃料电池参数的初步结果。所得结果也用于初步系统设计的评价。

The 25 kV AC railway power supply is widespread worldwide, but it produces a voltage unbalance on the upstream three-phase electric power transmission grid. Nowadays, the railway traffic increase exacerbates this unbalance issue. The use of power electronic converters appears to be an appropriate response. This paper first recalls the principle of the Railway Power Conditioner (RPC). This converter redistributes power between two railway sectors of the same substation. The study focuses on substations with either Scott or VV transformer arrangements. Simulations, considering the actual power consumption of a substation, are carried out. The sizing of converter is then discussed, taking into account the type of transformer (Scott or VV) and a control with a partial or total compensation of voltage unbalance.

This paper explores various design strategies for low-voltage, high current DC-DC converters, in order to optimize efficiency, volume, and mass, while keeping the project as simple and cost efficient as possible by using only on-the-shelf components, including inductor and heatsinks. The impact of topologies on both efficiency and compactness is studied for a specific aeronautical application. A 2kW 3-level FCML module has been developed for a 100V to 28V DC-DC step-down. It relies on pairs of paralleled EPC2022 GaN transistors to significantly increase converter power density. Two routing strategies to reduce parasitic switching loops are compared using computer simulations, with experimental verification. First experimental results on a prototype show an efficiency up to 98.4% for a specific power of 12.5kW/L.

The electrification of the transportation for a sustainable mobility is an outcome of the European strategy to reduce the environmental pollution. It requires the need to upgrade the electric distribution system with smart infrastructures able to locally manage the energy demand of the Electric Vehicles (EVs) charging systems. A first level of integration can be implemented in smart homes and nanogrids. In such scenario, local renewable energy sources, energy storage systems, smart appliances and EVs charging points can be managed in a smart way, with the aim to minimize the stress on the distribution grid given by the stochastic and intermittent behaviour of the aggregated demand. This paper presents a study focused on the energy flow optimization of a smart home equipped with a bidirectional EV charging wallbox, a local energy storage system (ESS) and two deferrable appliances (DAs). The impact of the smart charging, the DAs and the local ESS in the smart home are evaluated and discussed in detail considering different case studies.

The paper presents an Improved Impulse Response (IIR) method for the identification of capacity fade in LiFePo pouch 40Ah cells. The impulse response (IR) method for capacity-fade identification consists of building a pre-calculated table in which the cell voltage response to a input pulse current is measured and stored at a given State of Charge (SoC) for several iterations of full charge/discharge ageing cycles. Each stored impulse response can be used to calculate the voltage response to whatever input by means of convolution integral. However, since the same method can be also used for on-line SoC identification, it is necessary to investigate on the correlation between the cell impulse response, SoC and residual capacity, and the temperature. To this aim, an IIR method is here proposed that allows to evaluate the accuracy of IRs at different conditions of SOC, capacity fade, and temperature. A significative planning of charge-discharge cycles and IR measurements has been carried out to this aim. At present, only some rows of the IIR matrix have been already characterized.
提出了一种改进的脉冲响应(IIR)方法,用于鉴别40Ah袋状LiFePo电池的容量衰减。容量衰减识别的脉冲响应(IR)方法包括建立一个预先计算的表,在该表中测量电池电压对输入脉冲电流的响应,并在给定的充电状态(SoC)下存储几个完整的充电/放电老化循环迭代。每个存储的脉冲响应可用卷积积分的方法计算任意输入的电压响应。然而,由于同样的方法也可以用于在线SoC鉴定,因此有必要研究电池脉冲响应、SoC和剩余容量与温度之间的相关性。为此,本文提出了一种IIR方法,可以在不同的SOC、容量衰减和温度条件下评估ir的准确性。为此进行了有意义的充放电周期规划和红外测量。目前,仅对IIR矩阵的一些行进行了表征。

The impulse response (IR) method for capacity-fade identification consists of building a pre-calculated table in which the cell voltage response to a input pulse current is measured and stored at a given State of Charge (SoC) for several iterations of full charge/discharge ageing cycles. Each stored impulse response can be used to calculate the voltage response to whatever input by means of convolution integral. However, since the same method can be also used for on-line SoC identification, it is necessary to investigate on the correlation between the cell impulse response, SoC and residual capacity, and the temperature.

Lithium-ion Batteries (LiBs) have become the main energy storage chemistry for applications like electric vehicles (EVs). High-fidelity physics model of LiBs for online operation of a battery management system (BMS) is yet to be achieved and is ongoing research. In this paper, a novel algorithm is proposed to implement a pseudo-two-dimensional (P2D) model of a LiB using the Finite Volume and Euler Methods. Our proposed approach uses a novel root-finding algorithm that solves the P2D model with the same degree of accuracy as commercially available solvers but with much faster solving speeds, making our approach suitable for real-time applications.
