This paper presents two battery energy management (BEM) techniques for an electric vehicle (EV) traction system which incorporates indirect field-oriented (IFO) induction motor (IM) drive system. The main objective of the proposed BEM is to regulate IM’s speed while minimizing lithium-ion (Li-ion) bank state charge (SOC) reduction and health (SOH) degradation. In contrast most existing w...

The vehicle will generate an amount of current while the electric just starting to regeneratively brake. In order avoid impact high on traction battery, a novel electrohydraulic hybrid has been proposed. main power source is supplied by drive system, and hydraulic system performs auxiliary that fully exerts advantages system. A proper regenerative braking control strategy presented, parameters ...

in the present work, multidimensional modeling of open-cycle process of om355 engine was developed. calculations for computational mesh were carried out. the results of the model were validated by experimentally measured in-cylinder pressure and the good agreement between calculations and measurements approved the trustworthy of numerical code. results included pressure, temperature, emission a...

THERE is a growing interest worldwide in using alternative fuels, motivated by the potential benefits they can offer regarding emissions and energy security. Among the alternative fuels, natural gas has received special attention due to its vast proven reserves across the world. On the other hand, the composition variation of natural gas poses a challenge for the conventional lookup table-based...

this study mainly focuses on enhancing the overall efficiency of gas transmission networks. the authors developed a model with detailed characteristics of compressor and pressure reduction stations. following this, they suggested three different systems with gas turbine including: organic rankine cycle (orc), air bottoming cycle (abc), and abc along with steam injection (si-abc). in addition, u...
