Transportation is the leading source of logistics, and people contribute the significant primary emissions for increasing global warming, so we should avoid such a situation and concentrate on zero emissions. The range of the vehicle is the major problem (range-anxiety) in electric vehicles. Nowadays, researchers focus on range extender optimization since range extenders significantly improve the range of the vehicle with an auxiliary power unit (APU), which can prove consumer satisfaction. However, range extenders can recover energy by proposing the various configurations and systems of extended-range electric vehicles (EREV). Many industries and researchers summarize these efforts to optimize and find the solution for range-extenders. This paper reviewed the most suitable technologies for energy recovery and state-of-the-art topological constructions. The analysis of the study primarily concentrated on optimizing the cost of the systems, fewer emissions, and more fuel economy. The research is based on the range-extenders evaluation and summary for electric vehicles to guide automakers and researchers to invent other state-of-the-art configurations and topologies to obtain optimized EV ranges, namely, enhanced functionality and fewer emissions. A survey on specific extend-range electric vehicles and classification of EREV technologies, the performance of APUs, different control strategies of energy management in EREVs, and various existing difficulties are discussed and further enhanced for the future researcher EREV forecast offered by advanced technologies.

“…In addition, regarding the control method of torsional vibration of the range extender, early research mainly concerned vibration control during the start and stop processes of the engine (Guo and Wang, 2016, 2017a, 2017b; Guo et al, 2009; Hwang, 2013), as well as engine torque compensation control (Andert et al, 2017; Xiong et al, 2020); however, there has been less research on controlling the typical working process of the range extender.…”

The noise of extended-range electric vehicles is an industry concern, with the range extender providing the main noise source. Suppressing torsional vibration is important for reducing the noise of the range extender. A new combined model of system dynamics, generator control, range extender control, and active vibration control is proposed. The working state and torsional vibration characteristics of the model were analyzed under typical working conditions for the start, idling, stable operation, and stop stages. Under steady-state working conditions, for example, idling and stable operation stages, the torsional vibration of the range extender is mainly related to the excitation torque fluctuation of the engine, and when switching the operation stage (e.g., from idling to stable operation), it is mainly related to sudden changes in the generator and engine torque. An active vibration control model—including active torque composition controllers for engine torque fluctuation and switching the operation mode—is established. The simulation showed that active control effectively improved the torsional vibration and provided a new concept for controlling torsional vibration.

“…With the rapid development of automotive industry, vehicle's safety has been greatly improved, and more manufacturers focus on noise, vibration and harshness [1,2]. The ride comfort refers to keeping the vibration and impact response of vehicles within a certain range to ensure the comfort of passengers and integrity of goods [3,4].…”

A new type of non-inflatable metal tire is designed to prevent the flat tire caused by puncture and shrapnel penetration, and it can be used on star rovers and military or civilian wheeled vehicles. In order to study vibration damping characteristics of the new wheel, a specimen with the same size as the pneumatic tire (235/70 R16) is made for contrast tests. A filtering method is proposed to reduce impulse and random interference noise in collected vibration signal. Comparative analysis of ride comfort performance is conducted by solving weighted acceleration root mean square (RMS) values. The results show that the filtering method has a good effect, and ride comfort of the metal tire is slightly worse, while it has a better grasping ability. Therefore, some extended structures have been recommended to improve the vibration damping performance.
