Significant Factors

The selection of motor is one of the significant factors in Electric Vehicle design. When the motor is selected based on the conventional method, its performance during starting of the EV is met but it may fail in other operating regions of the driving cycle. This is because, acceleration requirements assume zero initial speed conditions and the requirements with different initial speeds is not accounted in the conventional method. This paper discusses an alternative procedure to compute the ratings of induction motor. The preliminary method to compute the ratings is carried out based on vehicle performance requirements. The improvisation techniques in the computation are then adopted to get required acceleration and transient torque capabilities of motor to meet the driving cycle requirements. The procedure is illustrated through simulation studies using MAT lab software.

Fuel Consumption And Emissions

With the economic development, transportation in the city becomes more crowded. Furthermore, fuel consumption is causing a serious problem of pollution in the urban environment. Hybrid electric vehicles are considered as a good solution compared to conventional internal combustion engine vehicles. In order to solve those problems, the components parameters of a series hybrid electric vehicle are selected and tested with the ADvanced VehIcle SimulatOR (ADVISOR) simulation tool, which is a software-based on Matlab_simulink. Then, an optimisation was done to minimise simultaneous fuel consumption and emissions (HC, CO, and NOx) of the vehicle engine. In addition, the driving performance requirements are also examined during the urban dynamometer driving schedule (UDDS) to fix their optimal control parameters. Finally, the results show that those steps help reduce fuel consumption and emissions while guaranteeing vehicle performance. Hence, the series hybrid electric vehicle greatly improves fuel economy and reduces toxic emissions.

The Impact

Increasingly electric vehicle design is looking forward the application of multiple ratio transmissions in place of traditional single ratio gearboxes. The choice of gear ratio has significant influence on vehicle performance, including range, acceleration, and gradeability. To study the impact of different transmissions on EV’s dynamic and economic performance, mathematical models of an EV is presented which is applicable to both single and multiple ratio transmissions. These transmission variants are then studied under different operating conditions to investigate how operating conditions in the motor work efficiency change with different transmissions. Here comparisons are made between 2-speed and single speed transmission. Then the reasons for the results are analysed.

Acquisition Method

The driving cycle of the vehicle is taken as the basis of the vehicle test, which plays an important role in improving vehicle performance and reducing energy consumption. Traditional fuel vehicles have been studied more in the current stage. Test conditions specifically for pure electric vehicles have been less studied. The data acquisition method of pure electric vehicle is studied and used to collect driving data. The driving cycle was established through the extraction and analysis of characteristic parameters. The research results can lay a foundation for the research of driving system optimization and energy consumption reduction of pure electric vehicles.

Selection Of

A surface-mounted permanent magnet (SPM) machine is widely used in many auxiliary parts of an electric vehicle, so its design level directly influences the performance of the electric vehicle. In the design process of the SPM machine, selecting the appropriate stator slot and rotor pole combination and pole arc coefficient is a necessary and important step. Therefore, in this paper, a 750 W machine is set as an example to research stator slot and rotor pole combinations and pole arc coefficients for the SPM machine. First, the design schemes of machines adopting different stator slot and rotor pole combinations are determined according to the winding coefficient, stator size, and electromagnetic performance requirements. Further, finite element models of SPM machines with different stator slot and rotor pole combinations are established by Ansys Maxwell. On this basis, the back electromotive force (back EMF), cogging torque, electromagnetic torque, and loss and efficiency of SPM machines are calculated and compared to select the better stator slot and rotor pole combinations. Further, effects of pole arc coefficient on cogging torque and electromagnetic torque are also researched to guide the selection of the pole arc coefficient in the design process of the SPM machine. Conclusions achieved in this paper will provide guidance for design of the SPM machine.
