In comparison with common combustion motor driven vehicles future electric driven vehicles vary more in their reachable range because of the high drive train efficiency and the different energy demand requirements in different drive conditions. One of the main issues to improve the overall range is the minimization of energy consumption. On the one hand an adapted energy management strategy is needed to achieve a more comfortable and acceptable equalization in the range. On the other hand it is important to recuperate mechanical, electrical and thermal energy, both inside and from the vehicles wherever possible. For example, it is thinkable to use the kinetic energy of braking vehicles outside the vehicle to power traffic lights. If a combustion process is used, a lot of waste thermal energy can be reused from the tailpipe. Or solar energy may be used. If a vehicle has a varying duty-cycle it makes sense to adapt the powertrain to suit the power need. Whatever the available energy, it has to go hand in hand with minimizing the energy consumption. This paper is based on the knowledge and combination of future technologies [2], which are useful to collect and convert energy coming from different sources within a vehicle.

Thermal effects are important in the power electronics for battery energy storage applications. This paper presents an experimental verification of the thermal stability of a MOSFET full bridge power inverter used in cascaded H-bridge inverter with split battery modules. The verification of the norm EN 61000-2-4 compatibility of the grid connected multilevel inverter is made by testing the submodules' current overload responses. Furthermore, the thermal capacity of the H-bridge using passive heat sink is analysed and the time constant is investigated. Efficiency measurements of the proposed topology are also made and the impacts of different currents and PWM switching frequencies are presented.

The paper presents the Markov reward approach to the comparative analysis of different types of traction electric motors for assessment the reliability associated cost of the ships' hybrid-electric propulsion systems. The preliminary results show that there are several appropriate machine types and it is necessary to decide, which kind of equipment has to be defined in advance for application respectively. In the paper, the Markov reward approach was developed for computing of average availability and the entire reliability associated cost, considering vehicle operational conditions and aging process of electric motors. Based on the obtained results of simulation, the decision about optimal type of traction electric motor for an icebreaking ships has been suggested.

The aim of this contribution is to study the driving load on electric vehicles through data mining methods. The battery pack is currently the major cost driver for these vehicles. Thus, battery durability is an important lever to economically establish electric mobility in the mass market. A segmentation modelling approach, based on unsupervised clustering algorithms, evaluates battery management system field data from BMW i3 vehicles such as state of charge, temperature and current in terms of their historical distribution. Clustering algorithms, due to their frequent use in the field of machine learning and information retrieval, are able to analyse big quantities of vehicle data with the aim to group vehicles with similar driving behaviour. The cluster analysis is further validated using the method of calculating respective silhouette coefficients to assess clustering performance and the influence of input parameters. The analysis of histograms concludes with the definition of the most common types of drivers worldwide. The vehicle clusters can further be correlated with battery ageing in order to find suitable 2nd life applications as part of stationary energy storage systems.

In this paper the attention is focused on a specific battery testing methodology for high power electric vehicles applications. The growing interest towards the working vehicles electrification increased the demand for a greater knowledge on battery performance. Due to the high power demand that characterizes these applications, a deeper understanding of the battery behaviour is necessary and requires specific testing techniques. In this work, a testing approach closer to real working conditions is considered. The attention is focused on the power demand that the ESS must satisfy to achieve certain vehicle performance. A numerical model of a working vehicle developed in previous works is used to test in Real Time a LiFePO4 cell in a Hardware In the Loop (HIL) testing configuration. The output Voltage-Current characteristic is thus compared with the same output generated by the numerical model of the considered battery.

In fact, compared to a committed capacity of less, compared to thermal plants, have times of utilization often far higher, leading to energy requirements to levels similar or even higher than those thermal, being the conversion factor of the electrical energy increasingly high. Leaving aside the procedural scheme energy certification, this article proposes a procedure, based on UNI EN 15193 and EN 15232 A possible to assess, through a numeric indicator of efficiency systems for electric lighting of the interior, they are kind of on / off equipped with systems for automatic adjustment dependent occupation of the premises or on the availability of daylight.
2010/31 / EU修订的指令2002/91 / EC引入了能源认证程序，旨在通过数字指标确定建筑物的整体能源效率，但注意到热电消耗。通常，功耗被错误地低估了，这种功耗需要非常注意。事实上，相比于承诺的容量少，相比于热电厂，有利用的时间往往要高得多，导致能源需求水平与热电厂相似甚至高于热电厂，电能的转换系数也越来越高。撇开程序方案能源认证不谈，本文提出了一个基于UNI EN 15193和EN 15232 a的程序，可以通过室内电气照明效率系统的数字指标来评估，它们是一种带有自动调节系统的开/关系统，取决于房屋的占用情况或日光的可用性。

Linear permanent magnet (PM) synchronous machines have been and continue to be viable candidates in many industrial applications where they exhibit higher performance than their rotating counterparts. In this paper, an analytical model-based optimization procedure of interior PM tubular linear synchronous machines (IPM-TLSMs) with fractional-slot-arranged winding in the armature, is developed in an attempt to enhance their electromagnetic force production capability. The proposed optimization procedure is initially-applied to an elementary concept. The force of the optimized concept is validated by a 2D finite element analysis (FEA). Then, the optimization procedure is extended to the entire machine. In spite of the force enhancement, it has been found that the machine is penalized by asymmetrical phase flux linkages. An approach to counter this limitation, through the reduction of the end effect, is proposed and validated by 2D FEA.

Interior permanent magnet (IPM) machines with spoke-type design are possible candidates for various applications, including vehicle traction. One of their drawback is the high demagnetizing current required in the flux weakening region to let the motor achieve high speeds. This problem can be mitigated by equipping the motor with a mechanical devices consisting of mobile rotor yokes. These move radially by centrifugal force so as to reduce the air-gap flux at high speed with no need for demagnetizing current injection. This paper addresses the problem of modeling such IPM motor to study its steady-state behavior under different operating conditions, both in the full-flux and in the flux-weakening region of the speed range. The approach uses a limited set of non-linear finite element analysis to characterize the dependency of motor flux linkages on the stator currents and rotor position. Interpolating functions are then obtained to mathematically capture this dependency and plug it into the steady-state electromechanical equations of the motor. The effectiveness and accuracy of the method are assessed through on-load measurements taken on the modelled motor both in low and high speed operation.

This paper presents a design of electrified hydraulic control system for a parallel type hybrid electric vehicle (HEV) with continuously variable transmission (CVT). Considering the hybrid characteristics and CVT feature which requires high line pressure to supply the demanded clamping force, three electrified hydraulic system: (1) 1-MOP+1-EOP, (2) 2-EOP and (3) 1-EOP were proposed and the energy consumption was evaluated. The EOP displacement was designed considering the demanded flow rate and pump efficiency. To investigate the amount of flow, pressure and energy consumption of the electrified hydraulic control system, an AMESim-MATLAB/Simulink co-simulator was developed for the target HEV, which consists of the vehicle powertrain and hydraulic system model. From the simulation results, it was found that 2-EOP system shows the smallest energy consumption while satisfying the required control, lubrication and leakage flow.
