Recharge Wrap-up: Comparing Nissan Leaf performance by climate, natural gas iffy for trucks

A new Carnegie Mellon University study looks at the effects of regional climate variations on the Nissan Leaf. The study shows (unsurprisingly) that the ambient temperatures of different regions have effects on battery performance and the use of climate control, both of which affect range. Efficiency and grid mix determine regional differences in emissions per mile. CMU enumerated many of the differences in performance across the US. For instance, on the coldest day of the year, maximum range can be 70 miles on the Pacific Coast, while it is less than 45 miles in the Upper Midwest. These differences in efficiency can also affect adoption patterns. Read more at Green Car Congress. Battery charger manufacturer CTEK has licensed WiTricity wireless charging technology. CTEK looks to commercialize the wireless power transfer tech for use with electric vehicle batteries, making the "plug-in" aspect of EV charging unnecessary. WiTricity's charging technology stands out for its ability for distance charging via magnetic near field. "We are excited to be on the forefront of the next generation of battery charging products for consumers and industry, and look forward to leveraging WiTricity's ground-breaking technology to bring a new level of convenience and ease of use to market," says CTEK CEO Jon Lind. Wireless charging is convenient for the public, but also especially useful for emergency vehicles, which need to be ready at a moment's notice but also keep electrical systems online while the car is parked.

Switching heavy trucking fleets from diesel to natural gas could make economic sense, but the environmental benefits aren't as certain, according to a new study from UC Davis and Rice University. Certain regions - particularly California, the Great Lakes and mid-Atlantic regions - could benefit from the switch with minimal investment. "But to have an environmental advantage for reducing greenhouse gas emissions would take significant policy intervention," says Amy Myers Jaffe, executive director for Energy and Sustainability at UC Davis. This would mean stricter efficiency standards for natural gas trucks, as well as stronger regulations for methane leakage. Read more in the press release from UC Davis below.

Nissan sells 100,000 Leaf EVs worldwide

Nissan sold 22,610 Leaf electric vehicles in the US last year, but the bigger story (literally) is how the company is selling the EV around the world. After selling the 99,999th Leaf to a woman in Virginia, Nissan sold the 100,000th Leaf to a man named Brett Garner in the UK. For the record, it took Nissan just about three years and one month to reach that mark, since the first Leafs were sold in December 2010. On a global scale, Nissan says the Leaf has a 45 percent market share among all the electric vehicles available. The car is available in 35 countries, but the bulk - as of the end of December, 42,122 units - have been sold in the US. That 99,999th Leaf was sold to Amy Eichenberger, a project manager overseeing major capital investments for the University of Virginia in Charlottesville (pictured below). Garner owns a dental practice in Fareham. You can read their gushing quotes about their new EVs in the Nissan press releases below. If you add in all of the electric vehicles that Nissan and partner Renault have sold (90,000 as of March, the last time official numbers were available), then the 100,000 was topped a while ago. Of course, electric vehicles remain a small portion of Nissan's global sales. In fiscal 2012, Nissan sold 4.9 million vehicles around the world. Still, 100,000 Leafs out of 4.9 million cars is far better than zero. Nissan LEAF global sales reach 100,000 units Nissan LEAF is best-selling EV in history with 45% market share The 100,000th customer is a British dentist After revolutionizing passenger vehicle segment Nissan is electrifying LCVs with the e-NV200 YOKOHAMA, Japan (January 20, 2014) – The 100,000th all-electric Nissan LEAF is being bought by a customer in the United Kingdom. The Nissan LEAF, the world's first mass-produced zero emissions vehicle, remains the best-selling EV in history with a 45% market share. Since its launch in December 2010 Nissan has seen the pace of sales increase consistently and 2013 was a record year. The LEAF is now available to customers in 35 countries on four continents. In Norway, the Nissan LEAF topped sales charts, out-selling conventional gasoline powered vehicles in October 2013. The 100,000th Nissan LEAF customer is Dr. Brett Garner, the owner of a dental practice in Fareham in the UK. "I have chosen my Nissan LEAF because I am very interested in its running costs," Dr. Garner said. "The cost of ownership such as maintenance, insurance and charging also convinced my wife.

The Scoot Quad is Nissan's small step toward EV car sharing

Halfway up Laguna Street, the panic set in. I might not make it up this hill. With my foot depressed all the way to the floor, I sucked in my stomach and started to pray. Yet again, I found myself in an unconventional way to get around on four wheels – but this time, I was on my own, and behind the wheel. Meet the Scoot Quad, aka Nissan New Mobility Concept, aka Renault Twizy. The many aliases reflect the path of descent from its development as a quirky French electric vehicle to its proliferation as a model for car sharing. The Quad resides in San Francisco as part of the Scoot fleet of shared electric vehicles and it's most certainly not for sale. As the line blurs between those who share cars for personal reasons and those who use them for business purposes, Scoot and Nissan came to an agreement in which a small number of New Mobility Concepts would join the Scoot fleet – which currently includes over 300 motorbikes. The added value of Scoot is the capacity for one-way rentals around the city, as well as a dedicated network of charging stations. "We think it's just the best way to get around the city for everyone," said Scoot fleet vice president Mike Waltman, explaining how 10 New Mobility Concepts made their way to San Francisco. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. The one-plus-one Twizy has been in production since 2012 and on sale in certain overseas markets, but it's entirely new for the United States, and it wears the Nissan badge here – kind of. No major changes were made to the Twizy when it became the New Mobility Concept, and similarly none were made in its "transformation" to the Quad. It sports the same insectile shape and the rear profile of a top hat, as well as an identical powertrain: a 13-kilowatt motor that produces 17 horsepower, routed to the rear wheels through a single-speed automatic transmission. Charging time is about four hours on a Level Two charger, made possible through Scoot's network of stations around the city. Its top speed is 50 miles per hour, but Nissan installed a governor at 25 mph to conform to US low-speed vehicle requirements. New Scoot members are required to successfully pass an exam before beginning to use the service, so that was my first order of business. After spending about 35 minutes going through a series of informational videos on the Scoot app, as any new member would do, I was ready to ride Scoot motorcycles.
