samples not only absorb UV but also the visible light photons. This is because the Fe substitution at Ti-site in CaTi1-xFexO3 lattice induces the band transition from Fe3d to the Fe3d + Ti3d hybrid orbital. The photocatalytic activity of Fe doped CaTiO3 samples for hydrogen production under UV light

Thermal issues associated with electric vehicle (EV) and hybrid electric vehicle (HEV) battery packs can significantly affect performance and life cycle. Temperature variations from module to module in a battery pack could result in reduced performance. As part of the U.S. Department of Energy

Abstract—The interior permanent magnet synchronous motor (PMSM) are widely used in the modern electric vehicle (EV) and hybrid EV. For the interior PMSM, there are two different control strategies, namely, the field oriented control (FOC) and the direct torque control (DTC). Based on a 15-k

Abstract—This paper presents a cascaded H-bridge multilevel boost inverter for electric vehicle (EV) and hybrid EV (HEV) applications implemented without the use of inductors. Currently available power inverter systems for HEVs use a dc–dc boost converter to boost the battery voltage for a

Abstract – As environmentally friendly energy takes center stage, interests for Electric Vehicles/Plug in Hybrid Electric Vehicles (EVs/PHEVs) are getting increase. With this trend, there is no doubt EVs will take large portion to penetrations of total cars. Therefore, accurate EV modeling

We propose a new speciation mechanism for hybridizing populations based on frequency-dependent sexual selection theory. In contrast to previous reinforcement and symmetric speciation models, this model does not require viability selection for male sexual traits, selection against unfit hybrids

Simulation of the PEM fuel cell hybrid power train of an automated guided vehicle and comparison with experimental results

Although still a small share of the automobile marketplace, hybrid vehicle models and sales have been growing steadily. It is now possible to buy several types of HEVs such as the Toyota Prius, Honda Civic, and Ford Escape. Even luxury brands such as Lexus and Porsche are working on sporty hybrid

We present a fast, low-cost approach to measure battery impedance ‘on-line ’ in a vehicle across a range of frequencies (1-2000 Hz). Impedance measurement has promise for improving battery management since it is a very effective non-invasive method of diagnosing the internal state of an electrochemical cell. It is useful for estimating temperature, ageing, state of charge (SOC) and for fault detection. The aim of this paper is firstly to explore the usefulness of impedance for estimating SOC, focusing on lithium-ion iron phosphate (LFP) and nickel manganese cobalt oxide (NMC) cells, and secondly to demonstrate the performance of a low cost impedance measurement system that uses an existing motor drive similar to that of an electric vehicle to excite the battery current. We find that measurements made with this system are accurate to within a few per cent of results from an expensive, bulky commercial system. For SOC estimation in NMC cells, the charge transfer resistance and SEI layer resistance vary significantly with SOC. In LFP cells the parameter variation is much less obvious, although the double layer capacitance of the full pack may be a useful indicator of SOC.
