This note extends the analysis of Lemoine, Kammen, and Farrell's paper "An innovation and policy agenda for commercially competitive plug-in hybrid electric vehicles" (http://www.iop.org/EJ/abstract/1748-9326/3/1/014003/) to cover the case of all-electric vehicles (EVs). We pay particular attention to grid impacts, break-even battery costs, and the three ways in which EVs could dramatically cha...

This addendum adds to the analysis of ‘An innovation and policy agenda for commercially competitive plug-in hybrid electric vehicles’ (D M Lemoine et al 2008 Environ. Res. Lett. 3 014003) to the case of all-electric vehicles (EVs). We pay particular attention to grid impacts, break-even battery costs, and the three ways in which EVs could dramatically change the results we obtained for plug-in ...

Many perceive electric vehicles (EVs) to be ecoenvironmentally sustainable because they are free of emissions of toxic and greenhouse gases to the environment. However, few have questioned the sustainability of the electric power required to drive these vehicles. This paper presents an in-depth study that indicates that massive infusion of EVs to our society in a short time span will likely cre...

As discussed in the previous chapter, electrification is the most viable way to achieve clean and efficient transportation that is crucial to the sustainable development of the whole world. In the near future, electric vehicles (EVs) including hybrid electric vehicles (HEVs), plug-in hybrid electric vehicles (PHEVs), and pure battery electric vehicles (BEVs) will dominate the clean vehicle mark...

This paper deals with the Electric Vehicle Scheduling and Optimal Charging Problem. More precisely, given a fleet of Electric Vehicles EVs and Combustion Engine Vehicles CVs, a set of tours to be processed by vehicles and a charging infrastructure, the problem aims to optimize the assignment of vehicles to tours and minimize the charging cost of EVs, while considering several operational constr...

Sustainability is today one of the key factors for car manufacturers worldwide. Electric vehicles (EVs) are clean, quiet and efficient and offer a great opportunity to keep our environment healthy. After the first era of EVs in 1900 (28% of the vehicles in the US were electric at that time [3]) the second era seems to have started: In the US and China one million electric vehicles are targeted ...

Electric vehicles (EVs) provide a tremendous opportunity to reduce greenhouse gas (GHG) emissions and save money at the same time. In the United States today, EVs generally result in substantially fewer GHG emissions compared to gasoline-powered internal combustion engine (ICE) vehicles. EVs are also typically cheaper to operate than ICEs. A recent Synapse analysis found that replacing ICEs wit...

In the last decade a rapidly growing interest in electrification of transport passenger cars could be noticed. The major motivation are the problems related to the use of fossil fuels in the transport sector such as crude oil dependency, greenhouse gas emissions (GHG) and air pollution. Electric vehicles (EV) are often presented as zero-emission vehicles. However, from a lifecycle CO2 perspecti...

Electric vehicle, as a clean energy industry, is an important branch. Electric vehicles not only are the energy of the electric user, but also can be used as mobile and distributed energy storage unit to the grid. As a precondition of safety operation for power grid, studies of EVs’ charging load characteristics is also the theoretical basis of intelligent scheduling EVs charging orderly. This ...
