Wireless charging is gradually making its way to the market. We’ve seen countless demonstration projects over the past few years, and a couple of OEMs have announced that they have wireless charging systems in the pipeline. Convenience is the most obvious reason to cut the cable, but wireless can deliver several other benefits as well… Read more »

2014 plug-in sales post 23% gain over 2013 as Tesla takes the lead and Mercedes and VW enter the race
2014 was another year of steady growth for EV sales. Some 12,874 plug-ins were sold in the US in December, a healthy gain compared to December 2013. For the full year, sales are up 23%. The Tesla Model S passed the LEAF and Volt to slide into the lead (doubtless thanks to the new P85D’s… Read more »
Tesla developing snakelike automatic charger
It’s classic Elon Musk: a tantalizing hint of a nifty (and picturesque) new feature straight out of a sci-fi novel. The Prophet of Palo Alto tweeted on New Year’s Eve: “We are actually working on a charger that automatically moves out from the wall & connects like a solid metal snake. For realz. This can… Read more »
Gallium nitride and silicon carbide expected to displace silicon in power electronics
Emerging materials such as gallium nitride (GaN) and silicon carbide (SiC) will eventually displace silicon in power electronic applications, according to a new report from Lux Research, which forecasts that the market for GaN power electronics will reach $1.1 billion, about 5% of the total market, by 2024. While silicon and SiC (SiC-on-SiC) each come… Read more »
Graphene wrapper enhances performance of lithium-sulfur batteries
Lithium-sulfur batteries are of great interest, as they could offer specific energy densities far greater than those of current lithium-ion chemistries. However, current designs are plagued by low efficiency and capacity degradation. A team of researchers from the University of Cambridge and the Beijing Institute of Technology has devised a three-dimensional sandwich-type graphene sheet-sulfur/carbon composite… Read more »
Ioxus announces new line of high-temperature ultracapacitors
New York-based ultracapacitor manufacturer Ioxus has introduced a new line of high-temperature 1250-Farad cells. According to the company, its proprietary Titan technology meets the requirement of automotive customers for ultracaps with a wider operating range that meets both cold and high temperature standards. Ioxus’ newest line of cells functions at temperatures ranging from -40 to… Read more »
How to calculate the cost of your EV conversion
More and more gearheads are converting their favorite cars (and boats) to electric drive. However, it can be tough to estimate how much a particular project will cost. The final bill may be anywhere from $6,000 for a basic city car to $125,000 for a state-of-the-art Tesla-killer. It all depends on the type of vehicle,… Read more »
DOE offers funding for research into fuel cells, batteries, Schottky diodes
The DOE’s Funding Opportunity Announcement (FOA) for fiscal year 2015, which spans the range of energy technologies, includes a few EV-related topics. Phase I grants of up to $225,000 will be made to small businesses to evaluate the feasibility of ideas that have commercial potential. Topics of interest include: Fuel Cell-Battery Electric Hybrid for Utility… Read more »
Researchers develop dendrite-free lithium films, an important step toward lithium metal anodes
There’s a lot of interest in using lithium metal as an anode material, because of its theoretical high capacity of 3,860 mAh g−1 (around ten times that of the graphite anodes used in typical Li-ion batteries). However, it doesn’t measure up in terms of cycle life and safety requirements, and one reason is the formation of… Read more »
Renault-Nissan sells 200,000 EVs
The Renault-Nissan Alliance has sold its 200,000th EV, highlighting its dominant position in the pure EV market, with a 58% market share. Renault and Nissan EVs have driven approximately 4 billion kilometers, saving 200 million liters of fuel and 450 million kilograms of carbon dioxide. The flagship LEAF is the top-selling plug-in vehicle in the… Read more »
