Nissan installs 1,000th CHAdeMO fast charger in Europe

While the European Union hasn't been very supportive of CHAdeMO stations, the fast chargers are seeing significant growth in the European electric vehicle (EV) infrastructure, with Nissan installing number 1,000 at the Roadchef Clacket Lane Services in Surrey, UK recently. In the past year, the number of CHAdeMO fast chargers nearly doubled in Europe, starting from about 600 stations in early 2013, and that's helping make EVs more useful. Nissan says that installation of a CHAdeMO station along Norway's E18 highway increased EV use eightfold there in the 18-month period after that station was installed. The new CHAdeMO station in the UK is available to use for free and, like other CHAdeMO stations, can charge a Nissan Leaf or other compatible EV up to an 80-percent charge in just under 30 minutes. Japanese automakers like Nissan and Mitsubishi are dedicated to the CHAdeMO but German and US automakers continue to support a competing technology in Europe and abroad, the SAE Combo DC fast charger. Tesla Motors has covered all the bases as it rolls out its $1,000 CHAdeMO adapter for its Supercharger stations. Nissan worked with Ecotricity, a UK green energy firm considered to be a pioneer in EV charging, for the Surrey installation. Nissan says that installing it on the M25 highway south of London helps EV drivers gain easy access to Kent and onward into Europe on one of the busiest roads in Europe. That will help drivers of the Leaf and the upcoming Nissan e-NV200 electric van to quickly extend their journeys, said Jean Pierre Diernaz, Nissan's director of electric vehicles, in the press release available below. 1,000th CHAdeMO standard quick charger installed in the UK UK has 18% of Europe's electric vehicle quick chargers Charger provides free, zero carbon electricity from Ecotricity Chargers recharge electric cars from 0-80% in 30 minutes Nissan has announced 1,000 CHAdeMO quick chargers have now been installed in Europe with the commissioning of the charger at the Roadchef Clacket Lane Services in Surrey, UK. The fast charging unit can recharge the batteries of compatible* electric vehicles - including the 100% electric Nissan LEAF - from zero to 80 percent charge in just 30 minutes, and at zero cost. The installation of the fastest type of chargers dramatically increases the uptake and usage of electric vehicles.

Infiniti's new VC-T changes the rules of small turbocharged engines

The upcoming Infiniti QX50 crossover does not get our pulse racing, no matter how shapely the QX Sport Inspiration concept that previews it may be. No midsize SUV does, to be fair. But it has something special under the hood – the world's first production variable-compression-ratio engine. That means the QX50's 2.0-liter turbo four, which makes 268 horsepower and 288 pound-feet of torque, will have up to 27 percent better fuel economy. Here's how it works. The trend of moving to smaller, turbocharged engines carries with it one big falsehood. Under low load when the turbo isn't needed, these engines are less efficient than an equivalent engine without a turbo because of the low compression ratio the turbo requires. That is, if you never need the extra power, you're wasting fuel. Turbocharged (and supercharged) engines use a lower compression ratio to prevent detonation. When you force extra air in a cylinder and mix it with fuel, it's more likely to prematurely go boom. Lowering the compression ratio prevents this problem, but it's less efficient. Infiniti's VC-T promises the best of both worlds, with a compression ratio that ranges from 8.0:1 for high-power turbo needs to a 14.0:1 ratio for fuel-sipping efficiency. At its heart the VC-T engine is a simple idea, but it's complicated to explain. Consider yourself warned. The photo below from Infiniti serves as a good visual overview. For the truly nerdy, this patent application covers the mechanical concept. Instead of having the pistons connected to the crankshaft, Infiniti's engine has a pivot arm with a connection on each end. One end connects to the piston, the other connects to a second lower shaft, which is controlled by an actuator arm. At any given time the engine's pistons move up and down according to the lobes on the crankshaft. But the actuator arm can change the angle of the pivot arm up and down. That is, the pistons still move in the same motion with the same stroke, but phase the entire stroke up or down. Move the pivot up and there's less room at the top, which means a higher compression ratio. Move the pivot down and the compression ratio goes down, too. As an added bonus, the lower shaft eliminates the need for counter-rotating balance shafts. Infiniti says this system works constantly and can vary the compression ratio to any number between 8:1 and 14:1. It also uses electronic variable valve timing on the intake valves to switch into Atkinson-cycle combustion for greater efficiency.

Nissan seeks tech tie-up without Renault as alliance nears end of road

Nissan is developing growth plans in areas such as software and electric vehicles (EVs) independent of Renault SA as the automakers work to finalize terms of a sharply limited alliance, said seven people with knowledge of the matter. Japan's third-biggest automaker by sales is seeking a partner outside the auto industry to develop software that connects vehicles to cloud-based services, two people involved in discussions said, without elaborating on candidates. That would address a relative weakness for Nissan as it tries to make cars "smarter and more connected," one of the people said. It is also working on an expanded strategy for all-battery and plug-in EVs for North American and Asian markets that will be for Nissan alone, they said. The revelations come as the alliance oversight board met this week to discuss a rebalance that will see Renault cut its stake in Nissan to 15% from 43% — matching the size of Nissan's stake in Renault — and Nissan gain reciprocal voting rights. Under the deal, to be finalized by mid-year, Nissan will also invest in the French automaker's new Ampere EV business. Imbalance had long riled Nissan executives who complained Renault did not pay its fair share of costs for innovation and development. Nissan's emerging strategy reflects a belief within the automaker that the 23-year-old alliance has run its course for many of the biggest challenges it faces, the people said. While Nissan sees continued savings in shared parts procurement with Renault, it has no plan to provide engineering support to Ampere, said two of the people, who all asked not to be identified because talks between the pair are ongoing. It also has no plan to provide its e-Power hybrid technology to a gasoline powertrain-focused joint venture Renault has with China's Zhejiang Geely Holding Group Co Ltd and Saudi Aramco Base Oil Co JSC, two of the people said. GOING SOLO Such go-it-alone thinking is shaping a longer-term plan that could be announced by year-end focusing on improved operational performance, electrification and software allowing self-driving and other "connected car" features, one of the people said. "Even if Renault gets something from Nissan, benefits moving in the other direction are hard," a second person with knowledge of Nissan's stance said.
