For switched reluctance machines, a major problem is the torque ripple, which causes increased and undesirable acoustic noise and possible irregular speed. This paper aims at determining optimal turn-on and turn-off angles for torque ripple reduction of a three-phase 6/8 switched reluctance motor/generator. A commutation-angle optimization technique is therefore implemented for both motoring and generating operation modes over an extended speed range.

In this study, an integrated powertrain-thermal energy management strategy (IEMS) was proposed for a power-split type plug-in hybrid electric vehicle. Dynamic models of the powertrain components including the engine, motor/generator, power-split transmission and battery were obtained with a thermal management system consisting of an engine (thermal part), radiator, positive temperature coefficient (PTC) heater, heater core and cabin. Using the powertrain and thermal management system model, a performance simulator was developed and simulation results of the powertrain components, engine coolant temperature and the cabin temperature were compared with the vehicle dynamometer test results. Based on the powertrain and thermal management system characteristics, an IEMS was proposed that considers not only the battery SOC, but also the ratio of PTC heater power consumption to battery power consumption. The simulation results of the IEMS were compared with the existing energy management strategy (EMS) and the IEMS improved fuel economy over EMS.

Hydrogen production with wind power generators is a very effective means to solve the problem of future energy supply. There is a method for producing hydrogen by using stand-alone wind power generators. However, there has been few report so far about experimental study of hydrogen production with stand-alone wind power generators. Therefore, this paper presents results of experimental analysis of hydrogen production by using stand-alone wind power generations. The experimental system is composed of Permanent Magnet Generators (PMG) as a wind generator. It is shown that each generator output can be controlled by DC chopper circuits to follow each MPPT operation independently.

The use of electrical machines (EMs) with variable-frequency drives (VFDs) results in electromagnetic interference (EMI). At high frequencies (HFs) of conducted EMI, the impedance of an EM insulation system fed from a VFD is small due to the parasitic capacitive couplings. Thus, the conducted EMI currents flow through the insulation into the other conductive parts of the machine or ground. This can cause damage to the insulation, accelerate corrosion and bearings, and influence other electrically and/or mechanically connected equipment in the system. In order to understand the phenomena of EMI and how to minimize it, one must understand parasitic capacitances in a VFD-cable-EM system. Many authors analyze the topic of parasitic capacitances of cables and machine's bearing capacitances. However, not many publications are focused on the detailed analysis of the windings. In most cases, the parasitic capacitances of the winding are represented as a part of a global equivalent RLC circuit. Some authors use simplified models such as solenoids, which are not adequate representatives of the actual winding topologies used in EMs. To date, not much attention is given to the actual distribution of parasitic capacitive couplings in the winding itself, especially for multi-layer coils. Therefore, it appears necessary to provide an overview of the models proposed in the literature and their implementation in the analysis of EMs. This paper presents capacitive couplings from the point of view of winding topology and conductor geometry, including insulation coating between conductors, and conductor and ground, which can be implemented in the winding equivalent RLC circuit, which can further be applied to analyze the machine's behavior at HFs. The discussion section at the end of this paper recommends further steps on how to determine the parasitic capacitive couplings in the future with more accuracy.

A method based on multi-objective optimization (MOO) is employed for the concept design of electric powertrain with in-wheel motor (IWM). The inherent challenges of IWM vehicles are powertrain packaging, increased unsprung mass, and motor cooling. Elimination of hub-reduction gearbox and adaption of high torque and low power electric motor can mitigate these challenges, but it degrades high speed gradeability. Simultaneous optimization of motor power, battery size and drivability parameters to size the powertrain components (electric motor and gearbox) is important for the effective design of powertrain layout. In this study, motor torque, base speed, and gear-ratio are taken as design variables to minimize the motor peak power and the battery size, while maximizing the drivability performance. AC induction machines and Li-ion batteries are considered for the discussion, but the same approach can be applied for other motor and battery types. The results are validated virtually using a high-fidelity vehicle simulator, which confirms the findings of MOO. The optimal powertrain layout includes a high torque (600Nm) and low speed motor without gearbox.

This paper discusses requirements and potential solutions for interoperable wireless charging systems for electric and plugin hybrid vehicles. Such technology is known as resonant magnetic induction charging, also referred to as wireless electric vehicle charging (WEVC). Future requirements for a WEVC system are: low cost, small package, high power transfer and interoperability. This paper discusses interoperability requirements as a key factor for successful deployment of WEVC systems. One key aspect analyzed in this paper is primary and secondary coils requirements as they relate to interoperability. Theoretical and practical studies have been conducted and a suggested interoperable solution is presented.

Research activities on electricity production from photovoltaics as carried out by the Photovoltaic Laboratory (PV LAB) at Bern University of Applied Sciences BFH, Burgdorf, Switzerland are presented. The activities are nested in one of the new Competence Centers for Energy Research set up by the Swiss Government in view of implementing the “Energy Strategy 2050”. Information on long-term energy yields is gained from measurements in a Swiss photovoltaic installation network. This unique network was started in the 1990s by the PV LAB, who today operates around 35 PV installations in Switzerland. The current research focus is on alpine sites as they produce a stable energy yield in winter. Photovoltaic-oriented buildings (PVOB) also contribute to electricity production in winter and form another research pillar of the PV LAB. In order to survey mounting work, the quality of PV modules in complex terrain or on façades of high-rising buildings, a new IR-multicopter was built.

In any hybrid or electrical vehicle, the electric motor can be used as an electric generator to impose a negative torque to the wheel providing the braking effect by recovering part of the kinetic energy used for charging the batteries. The main hypothesis of this study is to propose that a slip control is preferable to a braking torque control during the regenerative braking. The experimental results obtained with a three wheel recreational electric vehicle validate that the wheel slip control is an efficient regenerative braking strategy to ensure both the optimal energy recovery and the wheel adherence in spite of road uncertainties.

In a range-extended electric vehicle (RE-EV), the system efficiency decreases when the engine power is transmitted to the driving motor through the battery due to the charging and discharging energy conversion efficiency. To improve the system efficiency, a control algorithm is proposed using the route information. The control algorithm calculates the threshold power based on the battery charging amount and the demanded vehicle power from the target route. Using the threshold power, more engine power can be transmitted directly from the engine to the driving motor without charge and discharge process through the battery. It was found that the proposed algorithm reduces the fuel consumption of the target RE-EV, compared with the existing CD/CS control.

In this work, the electro-thermal behavior of a prismatic 50 Ah Lithium Manganese Oxide (LMO)/ Graphite cell is investigated. This cell is designed to be integrated in independent 12-cell modules, the global battery rack being composed of several modules. Optimal sizing of the thermal management system requires accurate knowledge end prediction of the thermal load associated with given operating conditions (current profile). It was obtained by identifying the electro-thermal model parameters for a single cell, carried out using a custom electrical bench able to impose a predefined current evolution, controllable by serial interface. From these measurements, the heating power is predicted using the Bernardi model. The identified electrical and thermal model parameters are then integrated in a 3D FEM transient simulation of the cell thermal behavior under realistic conditions.
