New study: Lithium cost swings unlikely to impact battery prices

Global lithium prices have doubled over the last six months, sparking a scramble to secure sources of the metallic element, and causing pundits to ponder whether white lightning may be the new black gold. However, a new study by a Carnegie Mellon University team has found that even large increases in lithium prices are unlikely… Read more »

New Union of Concerned Scientists report: EV life-cycle emissions are half that of an average gas car

Diehard fossil-fuel fans are fond of speculating that EVs may be no cleaner than legacy ICE vehicles, once the emissions resulting from power generation and manufacturing are taken into account. In fact, study after study, including reports from the Union of Concerned Scientists (2012), the University of Minnesota, and Carnegie Mellon University, has shown that,… Read more »

Yet another study: EVs emit less carbon than legacy vehicles, including electricity generation

EV skeptics have long speculated that EVs powered by grid electricity may be no cleaner in terms of greenhouse gas (GHG) emissions than ICE vehicles. Well, according to studies by the Union of Concerned Scientists, the University of Minnesota, and Carnegie Mellon University, the opposite is true. On average, EVs produce less well-to-wheels emissions than… Read more »

New study: EVs powered by natural gas reduce emissions by 40% compared to gasoline

It’s a fair question: Do EVs powered by grid electricity result in lower greenhouse gas (GHG) emissions than legacy ICE vehicles? On average, yes they do, according to studies by the Union of Concerned Scientists, the University of Minnesota, and Carnegie Mellon University. However, regional differences in the energy mix mean that EVs are much… Read more »

Researchers find a way to double transfer efficiency of wireless charging

Researchers from North Carolina State University and Carnegie Mellon University have found that adding a magnetic resonance field enhancer (MRFE) – which can be as simple as a copper loop – to a wireless charging system can boost transfer efficiency by at least 100 percent, and possibly as much as 5,000 percent. “Our experimental results… Read more »

New study: Nighttime EV charging may increase carbon footprint (Updated)

The question of the “long tailpipe” is a fraught one: does an EV deliver lower carbon emissions than a legacy vehicle if the electricity comes from dirty coal? The latest study to address the issue comes from Carnegie Mellon University, and it includes a couple of surprising new findings. “Regional Variability and Uncertainty of Electric Vehicle… Read more »

New study: Chinese more receptive to EVs than Americans

A new study by a team from Carnegie Mellon University, Ford and Drexel University suggests that Chinese consumers are more receptive to adopting battery-electric vehicles (BEVs) than their American counterparts. The study, “Will subsidies drive electric vehicle adoption? Measuring consumer preferences in the US and China,” was published in the journal Transportation Research Part A…. Read more »

New study: controlled charging helps manage grid fluctuations and reduces costs

As electric vehicles proliferate, more attention needs to be paid to their interaction with the electrical grid. Some fear that abundant EVs might drive up electricity prices if they are charged during times of peak demand. In a new study published in the journal Applied Energy, Carnegie Mellon University researchers found that controlled charging of… Read more »
