Short Circuit, the vehicle Muskegon Community College's Motorsports Club races at electric drag races, broke its old world record at the U.S. 31 Motorsports Park in Martin recently. On Sept. 9, the student-built electric car traveled a quarter mile in 11.7421 seconds, which translates to 110.57 mph. It actually was the slower, time that night. Driver Jeff Montella's first pass was at 112.37 mph. The dragster needed to make two trips down the track in times that were within 1 percent of each other to make the record. The new record beats the old record of 12.369 seconds. That was set at the Milan Dragway near Detroit in 2013 by Short Circuit. "The fact Muskegon Community College is setting records is pretty cool," said Al Thomas, MCC's automotive coordinator and MCC Motorsports Club's advisor and the Short Circuit's team manager. To shave more than a half-second off the record may not seem like a lot, but actually is "a real big different," said Thomas , who is Midwest regional director of the National Electric Drag Racing Association. Changes to the dragster's electric motor allowing for voltage and amperage to be turned up higher made the difference, Thomas said. He said track conditions were also likely better than the previous record set in late October on a cold slick track. Short Circuit was built and is maintained by students in the college's automotive technology program and the Motorsports Club. "The students love building, showing and racing their creations," Thomas said.

World leaders in 100% electric since 2010: Discover the Nissan LEAF today... http://www.nissan.co.uk/leaf ] THE Nissan LEAF will hit our TV and cinema screens from today as part of a new major advertising campaign that will reach millions of motorists. For the first time since January 2014, the 100% electric LEAF returns to TV, Video on Demand and cinema. The new campaign demonstrates EV leadership through a ‘talkers vs. doers’ concept illustrating their commitment to the future of electric vehicles. During the film there are some key messages communicated about the largest electric charging network with nearly c. 2 billion KM driven and Nissan being world leaders in electric vehicles since 2010. The 30 second spot targeting the brand audience coincides with an exciting time of the year in the TV calendar with the return of the Champions League and the start of the Rugby World Cup. Over the next three weeks, the LEAF advert will have a presence in the highly regarded Channel 4 programme Hunted, Sky Atlantic’s Game of Thrones and ITV’s Britain’s Biggest Adventures With Bear Grylls. The LEAF advertising will reach our cinema screens from the 18th September and will feature in films such as Legend, Hitman: Agent 47, Straight Outta Compton, American Ultra, Dope, The Transporter Refuelled, and A Walk In The Woods. The campaign reach is further extended with a heavyweight digital brand campaign running across key lifestyle websites. A social media campaign on the LEAF also begins on YouTube today and Facebook from next Tuesday.

As of today, FastNed has 38 stations with 50 kW CHAdeMO (and other standards like Combo and AC Type 2). “Good news! From today onwards every new Nissan LEAF sold in The Netherlands will be offered with two years of free unlimited Fastned fast charging. This means free charging within 20 minutes at 38 stations along the highway. This number is growing: before the end of this year we expect to have 50 stations operational. What’s also great about this deal: because the new Nissan LEAF comes with a bigger battery pack (30 kWh) you can drive up to 250 km on a charge, according to Nissan. The bigger battery combined with ubiquitous Fastned fast charging stations on convenient locations, drivers will experience real freedom.” This is a similar project to “No Charge To Charge” in the US. “That’s exactly the goal of Fastned: giving freedom to the electric driver. We are doing this by building a nationwide network of very reliable fast charging stations which always offer the fastest charging. The development of this network runs parallel with the arrival of ever better electric cars. In the coming years car manufactureres will bring to market cars with bigger and better batteries. Just like the smartphone industry vies for consumers with bigger screens or better cameras, the electric car market will be about faster charging and longer range. Fastned is building the fast charging infrastructure to secure nationwide coverage for all electric cars, at the most convenient locations. This way you’ll never run out of electricity. And just like a smartphone you can buy a car with or without a subscription.” [© insideevs.com] ... http://fastned.nl/en/ Fastned http://cleantechnica.com/2015/09/22/fastned-nissan-gave-us-ev-wake-call/ Fastned & Nissan Gave Us An EV Wake-Up Call September 22nd, 2015 by Roy L Hales Soon Every EV Will Offer +100 Miles http://c1cleantechnicacom.wpengine.netdna-cdn.com/files/2015/09/17-250_range_presentatie-6752cc-original-1442905182.jpg ...

[EVDL] EVLN: Nissan Euro EV Director Interview> 30kWh-Leaf EV, +more
http://www.driving.co.uk/news/interview-nissans-electric-car-chief-on-new-leaf-hybrid-qashqai-and-the-ev-tipping-point/ Interview: Nissan's electric car chief on new Leaf, hybrid Qashqai and the EV tipping point By Will Dron 16 September 2015 [image http://cdn.wp.driving.co.uk/get/2015/09/Nissan-Leaf-Jeasn-Pierre-Diernaz-interview.png Jean-Pierre Diernaz interview about Nissan electric cars ] Surging ahead IF THE 2015 Frankfurt motor show is anything to go by, plug-in cars that run purely or partly on electric power are still very much part of car makers' plans for the near future. In fact, after Tesla Motors' success with the Model S, the mainstream car makers seem to be redoubling their EV efforts. Peugeot brought along the Fractal Concept, BMW showed the new 225xe, 330e, 740e, and X5 xDrive40e models, as well as the i3 and i8 (perhaps the strain of it all was what led the company's chief executive to collapse on stage), Audi announced that it has 310-mile electric SUV in the works and Porsche is tackling Tesla head-on with its 330-mile, 600bhp Mission E four-door coupé. However, it wont be plain sailing for the established car makers. Upstart Tesla had an update for its long-range Model S electric car, boosting its power in the process to 762bhp, and its electric Model X SUV will be launching in 2016, followed by the Model 3 family car in 2017. According to the Society of Motor Manufacturers and Traders, the number of plug-in models on sale in the UK has more than doubled from 12 in 2012 to 25 this year. The VW group, which includes Audi and Porsche as well as Bentley, Bugatti, Lamborghini, Volkswagen, Seat and Skoda, plans to launch 20 electric and plug-in hybrid (PHEV) cars by 2020 (see the Driving section this weekend for more). The number of plug-in models on sale in the UK has more than doubled from 12 in 2012 to 25 this year Amongst all this, another company is fighting to remain at the head of the electric car pack. Nissan says it has sold 200,000 Leafs since the pure-electric hatchback launched in 2011, making it the world's best-selling electric car. It brought an updated Leaf to Frankfurt, with a new, longer range (155-mile) battery pack, along with a new extended-range electric (E-REV) crossover concept called Gripz. Driving asked Jean-Pierre Diernaz, Nissan Europe's electric vehicle director, about the new Leaf, Nissan's EV programme, and the future of electric cars in general. Driving: The Nissan Leaf is getting a 30khw battery – how much extra range will that yield? Jean-Pierre Diernaz: A 250km (155-mile) range, which will be – excluding the Tesla, which is in a different segment – the highest range of any competitor. Driving: What has changed technically? JPD: The battery is changing significantly. We don’t want to reveal how it is being constructed, but the physical size is exactly the same between the 24kWh and the 30kWh, so we have actually just increased the density of the battery. Driving: How has that been achieved? JPD: An evolution of the construction techniques and we are more mature in the way we develop the technology. It’s really a normal curve in innovation management. One thing that is important to notice is that the durability of the battery has been increased, so we’re going to move from a five year warranty to an eight year warranty. Driving: What else is new on this Leaf? JPD: We have a new onboard telematics system with a new look and feel, and additional functions. It will be faster, and the mobile apps that link to it – the way drivers charge their battery, the way you remotely charge and look at the battery level – is improved. I think customers will really appreciate this. It’s faster, simpler and has a better look and feel. Driving: When Leaf was launched in 2011, Nissan explained that 80% of daily driving in Britain is below 30 miles, so 100 miles of range was more than adequate to cater for our daily needs. Is the bigger battery an admittance that the original battery was too small? JPD: No. In fact, it’s still the same size. The statistics from 2011 in terms of how many people actually need more than 100 miles is still the same. What we’re talking about here is a difference between what you actually need, and what you believe you need, which is a big difference. There’s two things: one, battery technology is improving, therefore range is improving, and by doing so we effectively increase our accessible market, because more and more people will be interested in EVs, as the range effectively goes up. As far as your question is concerned, it’s not just that we admit the range was too low, because literally for all the commuters who are the number one target for EVs, you don’t need more than 150km a day. It’s just a perception; it’s to remove the anxiety. Claiming 250km is going to reassure everybody. Driving: Do you think the education process is taking longer than imagined? JPD: I don’t know if it’s longer than we imagine

Jonathan Porterfield, from Orkney, and Chris Ramsey, who lives in Aberdeen, completed the journey on Wednesday evening in 27 hours and 46 minutes. Earlier in the week, the duo drove from John O'Groats to Land's End in 28 hours and 38 minutes. They have submitted an application to Guinness World Records to have the quicker time recognised as a record. The pair, who only used the existing public rapid charger infrastructure, had hoped to make the round trip in 48 hours. Robert Llewellyn, who plays Kryten in the Red Dwarf comedy TV series and is an electric vehicle enthusiast, followed the pair's trip. After the men reached Land's End, Llewellyn tweeted: "Well done guys. Great achievement. Hope you find time for a nap now."

[EVDL] Safer Flow Batteries for Grid Storage
http://www.ecnmag.com/news/2015/09/rechargeable-battery-power-home-rooftop-solar-panels A Rechargeable Battery To Power A Home From Rooftop Solar Panels Thu, 09/24/2015 - 2:19pm A team of Harvard scientists and engineers has demonstrated a rechargeable battery that could make storage of electricity from intermittent energy sources like solar and wind safe and cost-effective for both residential and commercial use. The new research builds on earlier work by members of the same team that could enable cheaper and more reliable electricity storage at the grid level. The mismatch between the availability of intermittent wind or sunshine and the variability of demand is a great obstacle to getting a large fraction of our electricity from renewable sources. This problem could be solved by a cost-effective means of storing large amounts of electrical energy for delivery over the long periods when the wind isn't blowing and the sun isn't shining. In the operation of the battery, electrons are picked up and released by compounds composed of inexpensive, earth-abundant elements (carbon, oxygen, nitrogen, hydrogen, iron and potassium) dissolved in water. The compounds are non-toxic, non-flammable, and widely available, making them safer and cheaper than other battery systems. "This is chemistry I'd be happy to put in my basement," says Michael J. Aziz, Gene and Tracy Sykes Professor of Materials and Energy Technologies at Harvard Paulson School of Engineering and Applied Sciences (SEAS), and project Principal Investigator. "The non-toxicity and cheap, abundant materials placed in water solution mean that it's safe—it can't catch on fire—and that's huge when you're storing large amounts of electrical energy anywhere near people." The research appears in a paper published today in the journal Science. This new battery chemistry was discovered by post-doctoral fellow Michael Marshak and graduate student Kaixiang Lin working together with co-lead author Roy Gordon, Thomas Dudley Cabot Professor of Chemistry and Professor of Materials Science at Harvard. "We combined a common organic dye with an inexpensive food additive to increase our battery voltage by about 50 percent over our previous materials," says Gordon. The findings "deliver the first high-performance, non-flammable, non-toxic, non-corrosive, and low-cost chemicals for flow batteries." Unlike solid-electrode batteries, flow batteries store energy in liquids contained in external tanks, similar to fuel cells. The tanks (which set the energy capacity), as well as the electrochemical conversion hardware through which the fluids are pumped (which sets peak power capacity), can be sized independently. Since the amount of energy that can be stored can be arbitrarily increased by scaling up only the size of the tanks, larger amounts of energy can be stored at lower cost than traditional battery systems. The active components of electrolytes in most flow battery designs have been metal ions such as vanadium dissolved in acid. The metals can be expensive, corrosive, tricky to handle, and kinetically sluggish, leading to inefficiencies. Last year, Aziz and his Harvard colleagues demonstrated a flow battery that replaced metals with organic (carbon-based) molecules called quinones, which are abundant, naturally occurring chemicals that are integral to biological processes like photosynthesis and cellular respiration. While quinones in aqueous solution formed the negative electrolyte side of the battery, the positive side relied on a conventional bromine-bearing electrolyte that is used in several other batteries. The high performance and low cost of the technology, which Harvard has licensed to a company in Europe, hold the potential to provide scalable grid-level storage solutions to utilities. But bromine's toxicity and volatility make it most suitable for settings where trained professionals can deal with it safely behind secure fences. So the team began searching for a new recipe that would provide comparable storage advantages—inexpensive, long lasting, efficient—using chemicals that could be safely deployed in homes and businesses. Their new battery, described in a paper published today in the journal Science, replaces bromine with a non-toxic and non-corrosive ion called ferrocyanide. "It sounds bad because it has the word 'cyanide' in it," explains co-lead author Marshak, who is now assistant professor of chemistry at the University of Colorado Boulder. "Cyanide kills you because it binds very tightly to iron in your body. In ferrocyanide, it's already bound to iron, so it's safe. In fact, ferrocyanide is commonly used as a food additive, and also as a fertilizer." Because ferrocyanide is highly soluble and stable in alkaline rather than acidic solutions, the Harvard team paired it with a quinone compound that is soluble and stable under alkaline condit
