“…However, the smart grid can establish a two-way relationship between EVs and the grid. Bidirectional power flow can alleviate the pressure on energy generators and increase customer profits [39]. A study on using power generated from EVs and energy storage for smart homes is presented in [40], demonstrating that the power produced by EVs can be utilized for residential benefits.…”

Transportation electrification is pivotal for achieving energy security and emission reduction goals. Electric vehicles (EVs) are at the forefront of this transition, driving the development of new EV technologies and infrastructure. As this trend gains momentum, it becomes essential to enhance the quality of service (QoS) of EVs to encourage their widespread adoption. This paper has been structured with two primary aims to effectively address the above timely technological needs. Firstly, it comprehensively reviews the various QoS factors that influence EVs' performance and the user experience. Delving into these factors provides valuable insights into how the QoS can be improved, thereby fostering the increased use of EVs on our roads. In addition to the QoS, this paper also explores recent advancements in communication technologies vital for facilitating in-formation exchanges between EVs and charging stations. Efficient communication systems are crucial for optimizing EV operations and enhancing user experiences. This paper presents expert-level technical details in an easily understandable manner, making it a valuable resource for researchers dedicated to improving the QoS of EV communication systems, who are tirelessly working towards a cleaner, more efficient future in transportation. It consolidates the current knowledge in the field and presents the latest discoveries and developments, offering practical insights for enhancing the QoS in electric transportation. A QoS parameter reference map, a detailed classification of QoS parameters, and a classification of EV communication technology references are some of the key contributions of this review paper. In doing so, this paper contributes to the broader objectives of promoting transportation electrification, enhancing energy security, and reducing emissions.

“…However, on the other hand, these tendencies creates higher mobility in people [2]. This has led to rapid progress in the field of all-electric vehicles (EVs) [3,4] with regard to the appearance and development of new small EV types, such as electric mini-scooters and power-assisted electric bicycles [5], as well as the appearance of new transport services, such as rental scooters. Similar to the traditional vehicles with internal combustion engines, EVs are often supplied to the market in several versions [6], with electric motors of different power ratings that, however, do not significantly affect the scheme of the entire power train and, finally, the price of the vehicle.…”

Modular Segmented Motor for Power-Assist Wheelchairs: Proof of Concept

This paper presents an analysis of the opportunity to increase the price availability of small electric vehicles, such as electric scooters, such as bicycles and wheelchairs, by applying expandability and modularity principles to their motors. Assuming that, in many cases, small electric vehicles are brought to the market in several power/price versions, the authors of this report evaluate the possibility of combining different numbers of electromechanical modules while, at the same time, maintaining the unity of the entire drive/motor scheme, thus making the mentioned expandability possible. Power-assist wheelchairs are taken as an example of the application, where such expandability is reasonable. The application provides a price reduction for the less powerful wheelchairs in the case of less severe disabilities. To start, the authors briefly compare multidrive schemes that ground the principle of modularity at the electromechanical level. Then, they outline a radially segmented motor concept and discuss this concept using the example of a permanent magnet synchronous motor. In particular, they propose a methodology for the calculation of its parameters and calculate the particular design details of such a motor. The motor is then analyzed with the help of its mathematical model, as well as experimentally. This tentative evaluation of two 50 W segments (of a 300 W 6-segment motor) proves that the proposed segmented modularity concept is feasible, and that it requires a more detailed consideration of the parameters and the other implementation aspects (power driver, control, cooling) of the given synchronous motor. Moreover, the concept might be successfully utilized in the designs of other motor types.

“…According to the EV charging environment, EV monitoring can be divided into household EV monitoring and parking lot EV monitoring (Rastogi et al, 2019). At present, the minimum charging and discharging power of EVs sold on the market is 3 KW, which is 5-10 times that of most household appliances.…”

“…Due to the high power demand of EVs, it is significant to monitor such EV clusters: 1) For the parking lot with a large number of charging piles, its charging behavior has a certain regularity and synchronization, and such cluster charging behavior will generate a surge in the electricity demand (Li et al, 2021). In order to ensure intelligent charging of EVs, the power grid/third-party assistance can monitor EV charging in a more intelligent way (Dickerman and Harrison, 2010;Rastogi et al, 2019); 2) Charging an EV takes longer than filling up an internal combustion engine vehicle. The real-time queuing information for EVs can be provided by monitoring the parking lot equipped with charging piles, including the number of EVs being charged and the estimated waiting time (de Weerdt et al, 2016;Goel et al, 2020); 3) In the long-term vision, one of the goals of the smart grid is to optimize the power service economy by establishing a twoway relationship between the power grid and EVs (Zeff, 2016).…”

Monitoring the charging behavior of electric vehicle clusters will contribute to developing more effective energy management strategies for grid operators. A low implementation cost leads to a wide application prospect in nonintrusive monitoring for EVs. Aiming at the problem that traditional nonintrusive monitoring methods cannot identify unknown devices accurately due to the lack of classes, a nonintrusive monitoring method based on zero-shot learning (ZSL) is proposed in this article, one which can monitor the unknown types of EVs connected to charging piles. First, the charging characteristics of known EVs and unknown EVs are extracted by dictionary learning. Then EVs are classified by ZSL based on sparse coding. Furthermore, EVs are decomposed based on the proposed multimode factorial hidden Markov model (FHMM). Finally, the EV dataset of Pecan Street is used to verify the effectiveness and accuracy of the proposed method.
