“…During the last ten decades, much automotive industry started to change its motor structure and control techniques to improve EVs performance. In [14] majority of EV motors are using rare earth magnet material high cost, the main advantage which are of BLDC motor is high torque density and power density. In [15,16] main issues in BLDC conventional and in-wheel motors are torque ripple, faulttolerant capability, EMI, acoustic noise, control problem in field weakening ability, and high cost of PM materials.…”

Electric vehicles (EVs) are playing a vital role in sustainable transportation. It is estimated that by 2030, Battery EVs will become mainstream for passenger car transportation. Even though EVs are gaining interest in sustainable transportation, the future of EV power transmission is facing vital concerns and open research challenges. Considering the case of torque ripple mitigation and improved reliability control techniques in motors, many motor drive control algorithms fail to provide efficient control. To efficiently address this issue, control techniques such as Field Orientation Control (FOC), Direct Torque Control (DTC), Model Predictive Control (MPC), Sliding Mode Control (SMC), and Intelligent Control (IC) techniques are used in the motor drive control algorithms. This literature survey exclusively compares the various advanced control techniques for conventionally used EV motors such as Permanent Magnet Synchronous Motor (PMSM), Brushless Direct Current Motor (BLDC), Switched Reluctance Motor (SRM), and Induction Motors (IM). Furthermore, this paper discusses the EV-motors history, types of EVmotors, EV-motor drives powertrain mathematical modelling, and design procedure of EV-motors. The hardware results have also been compared with different control techniques for BLDC and SRM hub motors. Future direction towards the design of EV by critical selection of motors and their control techniques to minimize the torque ripple and other research opportunities to enhance the performance of EVs are also presented.

Medium-duty/heavy-duty trucks (MD/HDTs) are yet to be included in India's electric mobility plans. With the improvement of electric vehicle (EV) technologies, there is a growing interest in battery-electric trucks (BETs) from original equipment manufacturers (OEMs). The time is opportune to consider electrification as a future direction for road freight in India.Accordingly, this article presents the results of an energy consumption simulation study of a BET under Indian conditions. This study specifically considered an MDBET over a domestic drive cycle. These energy consumption figures can facilitate future studies that analyze the technical and practical feasibility of BETs in the country. In addition, the article provides the requisite groundwork for BET modeling for a simulation study by reviewing available EV powertrain systems and components. Appropriate powertrain considerations are thereby obtained for a typical medium-duty/heavy-duty battery-electric truck (MD/HDBET) in the Indian context.

“…Also, maintaining the battery to operate at an optimum temperature has improved the battery's life span and increased in EV range [14]. Then, opting for newer, highly efficient designed motors like SRM, PMSM, and BLDC over DC motors shows better performance and less fuel is consumed [15], [16]. In [17], the design of an energy-optimal control method to improve the motor drive system's efficiency and extend the driving range of electric vehicles is studied.…”

Design, Modeling and Hardware Implementation of Regenerative Braking for Electric Two-Wheelers for Hilly Roads

The electric vehicles which operate in hilly region gain potential energy while moving uphill. Some of this energy can be recuperated to charge the battery while the vehicle moves downhill by using regenerative braking. The speed of the electric vehicle while descending the slope of hilly roads is often low to ensure the safety of the passenger, hence requiring regenerative braking at low speed. Braking at low speed is quite challenging due to the low level of back electromotive force (EMF) during regenerative braking. This paper presents a modular regenerative braking circuit for electric scooters operating at low speeds. The proposed modular regenerative braking circuit's configuration, operation, and control scheme are explained in the paper. Here using the state-space averaging technique, the small-signal modeling of the braking circuit was done, and a Type-II current controller was designed to track the braking current reference. The proposed configuration also suggests fast switching between the motoring and regenerative modes by enabling or disabling the gate pulses to the inverter or DC/DC boost converter. This removes the need for a separate switch in the power circuit, hence increasing reliability and reducing cost. The operation of the proposed regenerative braking circuit, along with the overall motor drive-train of the vehicle, was simulated in MATLAB/Simulink. Its hardware implementation was conducted on a scaled-down laboratory test set-up. The simulation and experimental results verify the working of the proposed regenerative braking circuit and the effectiveness of the proposed control scheme.INDEX TERMS Modular regenerative braking, electric scooters, DC/DC converter, Type-II compensator, hilly roads.
