This paper suggests an Intelligent Control Algorithm for optimizing the charge and discharge of a battery pack used in a hybrid/electric vehicle. With precision control of voltage and current levels in secondary batteries, high performance and greater battery life can be achieved and the problems of overcharging and over discharging in batteries can be avoided. It uses cell isolation system, which controls the number of cells required specifically for an instantaneous load condition, thus reducing the overall internal resistance of battery pack, hence reduces losses due to heating.

Dynamic wireless electrical vehicle (EV) charging is the process of supplying electrically driven vehicles along their driving path with electric energy via a wireless energy transfer system. To increase the range of electric vehicles, a dynamic charging lane is to be installed on a highway. With regard to the amount of power needed, supply of electric energy is a major concern. High-power overhead lines or cables are not regularly available. In many cases, electrified railway lines run in parallel to or cross motorways. Consequently, the railway energy supply system can be used to feed the wireless energy transfer system. However, the design of such a link has to conform to the railway energy supply system as well as to the wireless energy supply system. This paper introduces and discusses concepts for such a link, including also the option of a bidirectional link. A companion paper presents the wireless charging system including its magnetic topology.

This paper proposes a procedure to apply a damping control to induction motor driven system in the single-pulse mode. In this mode, the amplitude of voltage vector is kept constant and it is determined by the filter capacitor voltage. Therefore, there is a possibility that the oscillation of the filter capacitor voltage deteriorates the torque control performance by fluctuation of the rotor flux. In this regard, this paper examines the oscillation of filter capacitor voltage and the dynamics of rotor magnetic flux by the frequency characteristics. This study reveals that the inversed value of the resonance frequency of LC input filter should be lower than the secondary time constant of the induction motor in order to avoid influence of the oscillation of the filter capacitor voltage to the rotor flux fluctuation. The proposed method is verified by the experimental tests with 0.75-kW-class miniature-model.

This paper considers thermal modeling of a 2 MW permanent magnet machine designed and manufactured for marine applications. The main focus is placed on the winding made of the Litz wire, and a practical approach to model heat transfer is presented. The proposed thermal modeling method, named segment-layer, is compared to traditional thermal models used mainly for standard winding configurations. In order to evaluate the accuracy of the developed thermal model, both simulation and experimental results are presented. In the simulation study, the proposed and traditional modeling methods are compared to a detailed finite element model of the Litz wire. Temperature measurements are carried out on the 2 MW machine prototype and a good agreement between the measurements and corresponding thermal model results is achieved. The suggested method is user-friendly and enables both analytical and numerical modeling of the Litz wire. Also, the parameters that play an important role in the winding heat transfer, e.g. impregnation goodness, can be easily implemented in the model developed in this paper.

Variations in the network architecture and component choices of superconducting DC networks proposed for future aircraft propulsion systems could have a significant impact on their fault response. Understanding these potential variations is key to developing effective protection solutions for these aircraft applications. To this end, this paper presents the results of sensitivity studies conducted using a representative model of a faulted superconducting DC network in which key system parameters are varied. Of the parameters considered, network voltage and the cable dimensions are shown to have the greatest impact on fault current profile whilst the rate of change of fault current is shown to be sensitive to network voltage and cable length. The paper concludes by exploring the implications of these findings on the prospective protection strategy for future aircraft propulsion systems.

The increasing complexity of ship's Integrated Power Systems (IPSs) led to the need of a review of conventional design process. Moreover, several stakeholders influence ship design, each of them aiming to protect its own interests, in particular when responsibility of accidents has to be defined. Dependability could be the tool to modify conventional design, transforming it into a dependability oriented design, as to properly manage the inherent system's complexity avoiding future liabilities. In addition to that, dependability could become a new index recognized by all the involved subjects, capable of establishing design quality. This paper addresses motivations to include dependability into internal processes for all the stakeholders involved in ship design process, as well as the motivations to demonstrate internal dependability levels to others subjects. Subsequently, a notional dependability oriented design process, tailored on IPS design, is presented, together with a discussion on the influence of every stakeholder on design steps. This with the aim of explaining dependability impact on design and to demonstrate how modifying conventional process important advantages could be achieved.

This paper reviews the main trends and opportunities to integrate in the power electronics systems dedicated to the More Electrical Aircraft (MEA). As a matter of fact, the emergence of this promising concept implies a revision of the usual aircraft architectures. As a consequence, it leads to the creation of new converters and strategies of energy management. In addition, with the challenging objectives announced by aircraft manufacturers, current technologies are not performant enough to ensure the expected requirements. They have to be highly improved or replaced by innovative ideas thanks to new explorations or technological ruptures in terms of topology, material and strategy. Thus, the emerging innovations and future developments in aeronautic are presented in this paper and assessed thanks to the literature and the expertise of the Avionics and Simulation Products department of Airbus.

This paper is focused on a series hybrid electric bus (SHEB). A rule-based energy management strategy is proposed by controlling the state of charge (SOC) of the battery (BT) and a variable output control for the auxiliary power unit (APU). Furthermore, a power splitter control is developed to split the power among BT and supercapacitor (SC). The optimization to obtain the values for the control levels is carried out with multi-objective genetic algorithm (GA). The aim of the optimization is to minimize the daily operating cost of the bus. The objective functions are the costs related to fuel and energy (BT and SC degradation by cycling cost, recharge from the grid cost) consumption. The results are given in a Pareto front with a set of optimal solutions, the optimal one will depend of an analysis on which objective has priority to be minimized and what are the consequences of this decision on the other one.

This paper proposed a wye-delta multi-function balance transformer based power quality control system (MBT-PQCS) to deal with the power quality problems in the single-phase power supply system. MBT-PQCS is mainly consists of a wye-delta multi-function balance transformer (YD-MFBT) and a three-phase full-bridge converter (FBC). It fully explores the inherent negative sequence current (NSC) suppressing ability of YD-MFBT, which makes the active power transformed by FBC is less than that of conventional transformer based compensating system. On the other hand, because YD-MFBT exits an interface for connection of active part, so FBC can be integrated with the main transformer without the help of other high-power auxiliary transformers. Hence the initial cost, installing difficulties, and covering space of the whole compensating system are reduced significantly. First, the current transforming relationship and compensating principle of MBT-PQCS are presented. Second, the detection and control methods are given as well. Finally, the simulation and experiment results verify the effectiveness of the proposed system.
