TL;DR: In this article, an aging study of a graphite LiNi1/3Mn 1/3Co/3O2 (NMC) Li-ion pouch cell with a nominal capacity of 10 Ah is presented.
186 citations
TL;DR: In this article, the authors present several aspects of charging regimes and charge acceptance and show that temperature is the most critical parameter and full charging within short times can be achieved only at elevated temperatures and a strong dependency of the charge acceptance during charging pulses on the pre-treatment of the battery can be observed.

TL;DR: A review of the current literature on EVs, the electric grid, and renewable energy integration is presented in this paper, where the economic, environmental and grid impacts of EVs are reviewed.
Abstract: Electric vehicles (EVs) and renewable energy sources offer the potential to substantially decrease carbon emissions from both the transportation and power generation sectors of the economy. Mass adoption of EVs will have a number of impacts and benefits, including the ability to assist in the integration of renewable energy into existing electric grids. This paper reviews the current literature on EVs, the electric grid, and renewable energy integration. Key methods and assumptions of the literature are discussed. The economic, environmental and grid impacts of EVs are reviewed. Numerous studies assessing the ability of EVs to integrate renewable energy sources are assessed; the literature indicates that EVs can significantly reduce the amount of excess renewable energy produced in an electric system. Studies on wind–EV interaction are much more detailed than those on solar photovoltaics (PV) and EVs. The paper concludes with recommendations for future research.
