“…Study by [62] have started to evaluate the possibility of integrating the cooling system for the CVT fluid and the motor's fluid, and this helps in making the powertrain system more compact and cost effective. Latest review on the lubrication for EV powertrain can be accessed here [95,96] which explored the possibility of integrating the cooling system for all components of an EV powertrain. The literatures also evaluate various possible lubricants for specific EV powertrain that have different requirements than the conventional ICE powertrain.…”

Electric vehicles (EV) are quickly gaining a foothold in global markets due to their zero tailpipe emissions and increasing practicality in terms of battery technologies. However, even though EV powertrains emit zero emissions during driving, their efficiency has not been fully optimized, particularly due the commonly used single-speed transmission. Hence, this paper provides an extensive review on the latest works carried out to optimize the power flow in EV powertrains using multispeed discrete transmission, continuously variable transmission and multi-motor configurations. The relevant literatures were shortlisted using a keyword search related to EV powertrain in the ScienceDirect and Scopus databases. The review focused on the related literatures published from 2018 onwards. The publications were reviewed in terms of the methodologies applied to optimize the powertrain for efficiency and driving performance. Next, the significant findings from these literatures were discussed and compared. Finally, based on the review, several future key research areas in EV powertrain efficiency and performance are highlighted.

“…These challenges are discussed in [39]. There are various new battery chemistries researched, and some of the latest popular batteries are the sodium-ion batteries [40], bio-inspired material for the secondary application of batteries [41], anionic battery [42], rechargeable Zn-air battery [43], potassium ion batteries [44], batteries related to particular applications such as EVs [45,46], non-aqueous, rechargeable aluminum batteries [47,48], and flexible zinc battery [49]. BMS plays a major role in state monitoring, energy management, communication between hardware and software and the protection of batteries from fault.…”

This paper presents a bibliometric analysis of battery state estimation in electric vehicles. In this paper, a quick study is performed on the top global research contributors, funding agencies, and affiliate universities or institutes performing research on this topic while also finding the top keyword searches and top authors based on the most citations in the field of electric vehicles. Trend analysis is done by using the SCOPUS and Web of Science (WOS) databases (DB) from the period of 2000 to 2021. Battery state estimation plays a major role in the battery present state based on past experience. Battery available charge and health knowledge is a must for range estimation and helps us acknowledge if a battery is in useful condition or needs maintenance or replacement. A total of 136 documents in SCOPUS and 1311 documents in Web of Science were analyzed. Through this bibliometric analysis, we learn the top authors, country, publication journal, citation, funding agency, leading documents, research gap, and future trends in this research direction. The author Xiong Rui has the most publications, and he is working at the Beijing Institute of Technology, China. The most common institution is the Beijing Institute of Technology, and China is the most highly contributing country in this research. Most of the publications are conference types in SCOPUS DB and article types in WOS DB. The National Natural Science Foundation of China provides the most funding. The journal Energies has the most publications related to this field. The most cited works are by the authors M.A. Hannan and L.G. Lu in SCOPUS and WOS DB, respectively. A statistical analysis of the top ten countries’ productivity results is also discussed.

“…According to Paris Agreement, global temperature increment in this century is limited to 2 °C by consistently reducing the emission of greenhouse gas globally [1]. Transportation sector is the primary contributor to greenhouse gases emission, while traditional internal combustion engine vehicles (ICEVs) contributed to 75 % of carbon monoxide emission [2]. Therefore, the invention of electric vehicles (EVs) and hybrid electric vehicles (HEVs) are encouraged to be invented as it will serve as a greener solution.…”

The market of electric and hybrid vehicles (EVs and HEVs) is expanding exponentially in recent years. It serves as a greener solution in the transportation sector as compared to internal combustion engine vehicles’ (ICEVs). Conventional lubricants used for ICEVs are not suitable for the EVs and HEVs as the latter operates on electric motors instead of combustion engines. Performance characteristics such as the electrical conductivity, thermal conductivity and copper compatibility are not considered by the ICEVs lubricant but are important for the EVs and HEVs. In this research, computer-aided molecular design technique is used to design the lubricant that is compatible with the EVs and HEVs. The lubricant properties considered are thermal conductivity, specific heat capacity, viscosity, density, and flash point. Group contribution (GC) property prediction model is utilized to ensure that the desired properties are possessed by the generated lubricant. There are six possible solutions of lubricant being generated and discussed. Other properties such as the electrical conductivity, copper corrosivity etc. are reviewed for future development. Additionally, the advantages and challenges of utilizing GC method in designing EVs and HEVs lubricant are discussed. This research serves as guidance for the comprehensive design of advanced lubricant of EVs and HEVs.
