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.

2013 Nissan Pathfinder: Wrap-Up [w/video]

Despite our tendency as enthusiasts to clamor for things like wagons and hot hatchbacks, it's hard to argue with the buying public's increasing demand for functional crossovers. In fact, the great SUV craze of the late-1990s has all but faded in favor of the easier-driving, better-packaged, more-efficient crossover. That's even true at the larger end of the market - just look at what happened when Ford redesigned its body-on-frame Explorer into a stylish and well-equipped CUV. And now look at the similar success Nissan has had in repurposing its rugged Pathfinder sport-ute as an appealing crossover.
But happily, we report the following line: out of every long-term vehicle Autoblog has ever tested, not a single one has been as in-demand as the 2013 Pathfinder Platinum you see here. After 13 months of solid use, we added 24,372 miles to the Pfinder's odometer - and that's without the vehicle ever leaving the hands of our Detroit-based team (sorry, West Coasters).
There's good reason for that high-demand usage, too. After spending a little over a year with our Mocha Stone tester (a color that earned this Nissan the nickname "Sweet Brown") we came to appreciate its vast versatility, comfort, all-weather prowess, and the way it absolutely ate up the miles on long trips. We drove it all over the United States, in all four seasons, filling it with our families, friends, and occasionally using its capacious cabin for sleeping on the road. Through good and bad, the Pathfinder was a trusty friend. But like any good friendship, that wasn't without a couple of fights.

Nissan's 'No Charge to Charge' is what incentives look like in the EV age [UPDATE]

Nissan knows that offering free charging can increase Leaf sales, so it only makes sense for them to expand the "No Charge to Charge" program. And that's exactly what happened yesterday. As previewed during the New York Auto Show, No Charge To Charge gives new Leaf buyers free charging at participating public charging stations – which is pretty much any public station – for two years. That's the kind of thing that simplifies the EV buying process, which can move units, Brendan Jones, director of Nissan EV sales and infrastructure, told AutoblogGreen. "There is an expectation that we'll get a sales increase out of this," Jones said. "All the dealer has to say is that we have one card that accesses all chargers and we have a promotion where you can get free charging. The more complexity we reduce, the more sales we get." "The more complexity we reduce, the more sales we get." – Nissan's Brendan Jones That all-access angle is important for the broader EV market, Jones said, calling the program, "The first valid step towards interoperability." Jones said there will be more surprise announcements soon. "The infrastructure companies really came together to support Nissan on this," he said, but added that, "What's good for the industry and EVs in general is good for Nissan." "Leaf customers are not shy about their ability to provide constructive criticism," Jones said, " and interoperability has always been a big concern." Now that many of the early adopters drive an EV, the next target audience are the people who are telling EV companies to "Make this easy for me and I will adopt," Jones said. "[Interoperability] is a necessity for the industry now. We know the experience is great once they drive it. This just takes away a barrier, that confusion at the dealership." And, in some areas in the US, No Charge To Charge is now live. There are 2,600 public stations (200 of them fast chargers) in the initial 10 markets, Nissan says. Those include: San Francisco, Sacramento, San Diego, Seattle, Portland (OR), Nashville, Phoenix, Dallas-Fort Worth, Houston and Washington, DC. Nissan hasn't announced where the next 15 markets will be, but we know that they will likely be wherever the Leaf is selling well and there are a fair number of DC fast chargers. As we reported in April, each charging session in the No Charge To Charge program is limited to 30 minutes if you're plugged into a CHAdeMO fast charge station and to an hour at a Level 2 station.
