This paper cautions that the adoption of electric vehicles with the aim of reducing greenhouse gas emissions must balance that beneficial effect against increased water consumption. It recommends battery electric vehicles charged by solar energy as the best solution.
Electric vehicles (EVs) are widely regarded as the key to finally making private mobility clean, yet virtually no research is being conducted on their potential contribution to the expansion of impervious surfaces. This study aims to start a discussion on the topic by exploring three relevant issues: the impact of EVs’ operating costs on urban size, the space requirements of charging facilities, the land demand of energy production through renewables.

Accurate health estimation and lifetime prediction of lithium-ion batteries are crucial for durable electric vehicles. Early detection of inadequate performance facilitates timely maintenance of battery systems. This reduces operational costs and prevents accidents and malfunctions. Recent advancements in “Big Data” analytics and related statistical/computational tools raised interest in data-driven battery health estimation. Here, we will review these in view of their feasibility and cost-effectiveness in dealing with battery health in real-world applications.
Lithium ion batteries (LIB) continue to gain market share in response to the increasing demand for electric vehicles, consumer electronics, and energy storage. The increased demand for LIB has highlighted potential problems in the supply chain of raw materials needed for their manufacture. Some critical metals used in LIB, namely lithium, cobalt, and graphite are scarce, are not currently mined in large quantities, or are mined in only a few countries whose trade policies could limit availability and impact prices.
The development of new high-efficiency magnets and/or electric traction motors using a limited amount of critical rare earths or none at all is crucial for the large-scale deployment of electric vehicles (EVs) and related applications, such as hybrid electric vehicles (HEVs) and e-bikes. For these applications, we estimated the short-term demand for high-performing NdFeB magnets and their constituent rare earths: neodymium, praseodymium and dysprosium. In 2020, EV, HEV and e-bike applications combined could require double the amount used in 2015.
