This paper concerns the design optimization of two axial-flux permanent magnet (AFPM) machines, aimed to be used as a direct drive in-wheel motor for the propulsion of a solar-powered electric vehicle. The internal stator twin external rotor AFPM machine topology having either a distributed or toroidal stator winding configuration is investigated. The objective of the design optimization is to minimize the total volume of the machine. A gradient-based optimization algorithm is employed on a non-linear 2D equivalent motor model. The motor model consists of coupled electromagnetic and thermal models based on an Isogeometric Analysis (IGA) approach. A wide range of pole-pair numbers are optimized and compared in terms of power density and efficiency. Finally, the radius to evaluate the 2D model as a function of the pole-pair number is given, which minimizes the discrepancy with respect to the 3D finite element method (FEM).

An automotive, fluid-control solenoid valve is composed of an electromagnetic reluctance actuator and a near-constant-force spring. Its motion profile is characterized by short closed-to-open transition times which demand fast switching, while valve lifetime improves by minimizing the impact velocity, i.e. a soft landing. In this paper, a cascaded position- and current-feedback control is designed and implemented on nonlinear, axisymmetric magnetostatic finite element simulations of a low-energy solenoid valve actuator. By applying the cascaded control, actuator performance is improved considerably, as a soft landing, a timely actuation, and an increased energy-efficient device have been obtained.

This research evaluates the energy consumption and carbon dioxide (CO2) emissions of electric vehicles in Nordic climate conditions. The energy sources and CO2 emissions of electricity generation in the European Nordic countries were presented. The vehicle energy consumption was analyzed based on numerous simulations in different driving cycles and ambient conditions. Daily average energy consumption was calculated based on the temperature data from three different cities in Finland. Vehicle operation CO2 emissions were calculated based on monthly average energy consumption and average CO2 emissions of the electricity generation. The research results clearly show that the energy consumption of electric vehicles is much higher in cold climate conditions. Because the CO2 emissions of the electricity generation are high during the winter months in Finland, the vehicle CO2 emissions are much higher during winter months than in the summer. Due to the relatively low CO2 emissions of the electricity generation in most of the Nordic countries, the CO2 emissions from the vehicle production are more important during vehicle lifecycle.

As part of the ongoing NGC-project (Next Generation Car) related to the research of new technologies for future road vehicles at the DLR, this paper is dedicated to the substitution of an optimization method of a brushless electrically excited synchronous machine for use in electrical vehicles. In this application high torque densities and small vibrations are needed, so an optimization of torque and torque ripple is done. As optimization parameters torque ripple reduction techniques as skewing, cosine formed tooth and width of tooth are chosen. The combined multi-parameter optimization is necessary because of interactions between the optimization parameter effects. An analysis for a machine of 25 kW, used in urban electric vehicles, is done with different excitations to build up the working points. The results show a large effect of increasing skewing to decrease torque and increase ripples independent of excitation. The effects of the other techniques are smaller. The cosine form has in the example optimization a strong dependency on excitation.

In this paper proposes an experimental comparison between different rainfall harvesting devices and the study of the corresponding electrical rectifying circuit. More in detail, three harvesting structures are considered: the cantilever, the bridge and the floating circle. For each of the proposed structure, different waveforms have been acquired and discussed. The processed data have been compared in order to suggest the best choice for the rectifying circuit, from the simplest one to the most endorsed in the technical literature.

This paper focuses on the environmental and economic optimal operation of microgrid (MG) in various scenarios. An AC/DC hybrid MG including photovoltaic, diesel generator, lithium battery, electric vehicle charging points is analyzed. Considering the operation constrains of MG, a constrained multi-objective optimization problem (CMOP) is built. The optimization objectives of the proposed CMOP are the fuel cost, depreciation expense and emission cost of distributed generators. The fuzzy comprehensive evaluation is introduced for conversion from the multi-objective problem to a single-objective one. Then the comprehensive learning particle swarm optimization (CLPSO) is applied for the solutions of distributed generators' outputs. Optimization results in grid-connected and islanded modes demonstrate the effectiveness of the proposed models, methods, and algorithm.

DC/DC autotransformers present several advantages compared to Front-to-Front (F2F) topologies. This work presents the Transformerless (TL) DC/DC autotransformer topology, which consists on the substitution of the AC transformer in the DC/DC autotransformer for an AC filter, with the objective of reducing its cost. The TL topology is modelled, its control presented and its operation validated by means of simulations. Also, the losses of the converter are estimated for partial and full load.

This paper presents a comparison between efficiencies of the conventional two-level Dual-Active-Bridge (2L-DAB) and the Multi-Level Dual-Active-Bridge (ML-DAB) DC-DC converters for solar applications. A semiconductor chip-area-based comparison is employed to have a fair comparison between the two topologies. The definition of average efficiency for the European solar mix is utilized to make a comparison specific for a solar application. The rated power of the converters is 1 MW, and the switching frequency is swept from 10 kHz to 80 kHz to investigate its effect on the efficiencies of the converters. It has been shown that for a same amount of investment on the semiconductors, the 2L-DAB outperforms the ML-DAB both from efficiency and an operating junction temperature point of view. It has also been demonstrated that, by less than 70% more investment on the semiconductors, the efficiency of both converters can be increased by at least 0.7% while the operating junction temperature of the MOSFETs can be reduced by 50°C.

The paper deals with a 3D-FEA based comparison of four topologies of claw-pole alternators equipped with a dual excitation, namely: (i) the series-hybrid excited claw-pole alternator (SHECPA), (ii) the parallel-hybrid excited claw-pole alternator (PHECPA), (iii) the hybrid excited brushless claw-pole alternator (HEBCPA), and (iv) the PM-assisted hybrid excited brushless claw-pole alternator (PMA-HEBCPA). The study is initiated by a description of their topologies and an analysis of their rotor-stator flux linkages. Then, a special attention is paid to their back-EMF production capabilities, with emphasis on the no-load characteristics and the back-EMF wave-forms and harmonic contents. In order to highlight the possible improvements introduced by the dual excitation, the comparison is extended to the case of the conventional CPA which is taken as a reference.

The Second-Life use of retired electric vehicles' (EV) batteries in stationary storage systems can not only help to reduce the CO2 footprint of EVs but also generate a significant residual value before recycling. However, the nowadays repurposing process from vehicle batteries to Second-Life storage systems is characterized by time and cost intensive process steps like disassembly to module level and manual state of health (SOH) measurements with costly test equipment. Therefore, the aim of this paper is to introduce a novel cloud-connected battery management approach to estimate the residual value of vehicle batteries in respect to various potential Second-Life applications. Based on measurement data acquired by the battery management system (BMS) during regular vehicle operation, the state of the vehicle battery is continuously updated in the form of an electric-thermal system model on a server backend. In combination with an empirical aging model, the degradation behaviour for different Second-Life scenarios' load cycles can be predicted and thus the residual value calculated. Besides the introduction of the overall concept, the focus of this paper lies on the electric-thermal modelling approach as well as the algorithms used for dynamic electric parameter estimation.
