“…It is also possible that technological progress not only improves financial performance, but also reduces carbon emission. This is consistent with the research results of many scholars (Ambrose et al, 2020;Ehrenberger et al, 2020;Su et al, 2020). In general, NEV needs more TI than traditional vehicles .…”

Vehicle industry has made great contribution to human progress. However, in the process of vehicle operation, a large number of carbon compounds are emitted, which brings serious environmental problems. As one of the important means of vehicle carbon emission governance, the development of new energy vehicles(NEVs) has attracted much attention. The behavior and performance of NEV enterprises are highly concerned. Using Chinese 23 NEV vehicle enterprises' data from 2011 to 2018, this paper evaluates the carbon emission performance with the super-efficiency slacks-based measure (SE-SBM) model based on unexpected output, and then constructs STIRPAT model to analyze the influencing factors of carbon emission performance.The results indicate that, firstly, the carbon emission performance of China's NEV enterprises is not ideal at present, but it is increasing year by year. Secondly, the carbon emission performance of different NEV enterprise is distinct in the same year, and the carbon emission performance of the same NEV enterprise is distinct in different year. Thirdly, technological innovation, government support and free cash flow have significant positive impact on the carbon emission performance of NEV enterprises, while debt constraint, energy intensity and enterprise size have a significant negative impact on the carbon emission performance of NEV enterprises.

“…Therefore, it is necessary to reduce the energy consumption of NEV. TI can achieve this goal (Ambrose et al, 2020;Ehrenberger et al, 2020). Thirdly, the effect of TI is related to NEV's enterprise governance structure and its initiative for R&D activities (Liu et al, 2018).…”

“…The use of full electric vehicles avoids carbon emissions as far as driving the vehicle is concerned, although the electricity required to recharge the batteries produces carbon emissions unless it is generated by renewable energy sources. Nevertheless, other electric vehicles such as hybrid and plug-in vehicles cannot be considered emissions free since they combine an electric engine and an ICE one [41,42].…”

This paper is focused on the determination of real driving ranges for electric vehicles (EV’s) and how it influences fuel consumption and carbon emissions. A precise method to evaluate the driving range of an EV can establish the correct reduction in GEI amount, mainly CO and CO2, ejected to the environment. The comparison of the daily driving range between an internal combustion engine (ICE) vehicle and an EV provides a useful tool for determining actual fuel saved during a daily trip and a method to compute carbon emissions saved depending on the type of ICE vehicle. Real driving range has been estimated on the basis of a daily trip consisting of five different segments, acceleration, deceleration, constant speed, ascent and descent, which reproduce the different types of driving. The modelling has been developed for urban routes since they are the most common and the most polluted environment where the use of electric vehicles is applied. The effects of types of driving have been taken into account for the calculation of the driving range by considering three main types of driving: aggressive, normal and moderate. The types of vehicle in terms of shape and size as well as dynamic conditions and the types of roads have also been considered for the determination of the driving range. Specific software has been developed to predict electric vehicle range under real driving conditions as a function of the characteristic parameters of a daily trip.

“…A second important parameter that affects the pollutant emission performance is the number of engine starts and the time that the thermal engine is not working. [24][25][26] Particularly, for Vehicle 3 the higher NO x emissions are observed at tests V 3 -T 3 and V 3 -T 4 , the route that includes uphill and downhill driving and the reverse RDE respectively. For V 3 -T 3 , the high NO x emissions were observed at the engine starts indicated in Figure 10(c), points where catalyst temperature was lower than 300°C.…”

Vehicles’ powertrain electrification is one of the key measures adopted by manufacturers in order to develop low emissions vehicles and reduce the CO2 emissions from passenger cars. High complexity of electrified powertrains increases the demand of cost-effective tools that can be used during the design of such powertrain architectures. Objective of the study is the proposal of a series of real-world velocity profiles that can be used during virtual design. To that aim, using three state of the art plug-in hybrid vehicles, a combined experimental, and simulation approach is followed to derive generic real-world cycles that can be used for the evaluation of the overall energy efficiency of electrified powertrains. The vehicles were tested under standard real driving emissions routes, real-world routes with reversed order (compared to a standard real driving emissions route) of urban, rural, motorway, and routes with high slope variation. To enhance the experimental activities, additional virtual mission profiles simulated using vehicle simulation models. Outcome of the study consists of specific driving cycles, designed based on standard real-world route, and a methodology for real-world data analysis and evaluation, along with the results from the assessment of the impact of different operational parameters on the total electrified powertrain.
