Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years, increase in e...

In this work the fuel consumption of two vehicles is compared. For investigating the fuel consumption a whole vehicle simulation is developed with the SmartPowerTrains library and the SmartElectricDrives library. Both librarys are written in Modelica language. As a reference vehicle a conventional vehicle with manual transmission is modeled. A parallel hybrid electric vehicle with a starter/gen...

Thanks to the development of electric motors and batteries, the performance of EV is greatly improved in the past few years. The most distinct advantage of an EV is the quick and precise torque response of the electric motors. A further merit of a 4 in-wheel-motor drived electric vehicle (4WD EV) is that, the driving/braking torque of each wheel is independently adjustable due to small but powe...

Capacitive power transfer (CPT) technology is an effective and important alternative to the conventional inductive power transfer (IPT). It utilizes high-frequency electric fields to transfer electric power, which has three distinguishing advantages: negligible eddy-current loss, relatively low cost and weight, and excellent misalignment performance. In recent years, the power level and efficie...

More and more popular electric vehicles are excellent application platforms for steerby-wire (SBW) system. Handling stabilities and active safety are greatly improved when SBW is adopted in electric vehicle. The proposed new architecture of SBW electric vehicle is introduced, its dynamics model is built after the principle and structure. The algorithm achieves the yaw motion of electric vehicle...

For Electric Vehicles (EVs), Weight and losses reduction are important factors not only in reducing the energy consumption and cost but also in increasing autonomy. This paper describes the application of an evolutionary algorithm for multiobjective optimization in the traction chain (TC) of pure EV. In this study, the optimisation algorithm is based on the Strength Pareto Evolutionary Algorith...

This paper reviews and improves a recently proposed model of road network dynamics. The model is also adapted and generalised to represent the patterns of battery consumption of electric vehicles traveling in the road network. Simulations from the mobility simulator SUMO are given to support and to illustrate the efficacy of the proposed approach. Applications relevant in the field of electric ...

The most distinct advantage of electric vehicle is its quick and precise torque generation. However, most electric vehicles developed until now have not yet utilized it. In this paper, two novel traction control techniques of electric vehicle using this advantage are proposed. One is the model following control and another is the optimal slip ratio control. The basic effectiveness of the propos...
