2014 Nissan Dayz Roox is the littlest high-roof van you ever did see

Even average production cars from Japan often seem very conceptual to US eyes. Throw in typical, nonsensical-quasi-English-words name like "Dayz Roox" and you'd be forgiven for thinking this Nissan box on wheels was still a designer's dream. But the fact is that the Nissan Dayz is a model currently on sale, and this Roox version is the latest take on the micro-van, which is a popular segment in Japan.
In fact, this generation of Dayz is the first minicar that Nissan has developed completely in-house, and the thing has been selling astoundingly well in its first stint on the market (30k units in month one month, says Nissan). So it's unsurprising that the company is looking to expand the range with a model that is more fully featured.
The Roox (we have no clue as to where that name came from, or what it means) would appear to be a high-roof version of the three-cylinder Dayz minicar - in fact Nissan goes so far as to call it an "Impressive Super Height Wagon." Features like automatic sliding doors, Around View Monitor and UV-insulated glass are all luxuries in kei-class car. The press release also specifies that the Roox is tall enough to swallow a 27-inch bicycle.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Renault, Nissan limit French government interference

Renault and Nissan are taking action to limit the influence that one can exercise over the other's operations. The measures, announced by both automakers after meetings of their respective boards in Paris and Tokyo, aim to keep each other at arm's length. But more than that, they seek to cap the degree of influence which the French government can bring to bear on either automaker. The steps are being taken in response to investment moves by the French state. While the government's investment arm – known as the Agence des Participations de l'Etat (or state participation agency) – previously controlled 15 percent of Renault's shares, it increased its holdings this April to 19.73 percent. The action sparked concerns at Renault that the French government would attempt to dictate operating procedures to both automakers, potentially to favor production in France over other locations. Given that Renault holds a 43-percent stake in Nissan, the Japanese automaker grew concerned over potential French state interference as well. To assuage those concerns, Renault, Nissan, and the French government came to an agreement with three vital clauses. Most importantly, despite its nearly 20-percent holdings, the French government will be granted only 17.9 percent of voting rights in Renault (to be extended up to 20 percent under certain exceptional circumstances). Renault (and by extension the French government) will also be prevented from interfering in Nissan's governance. With those measures in place, Nissan will not seek more voting rights based on the 15-percent stake which it, in turn, holds in Renault. Having successfully concluded the deal and hedged against the threat of government interference, the Renault board reasserted its confidence in Carlos Ghosn. Through the unique terms of their alliance, Ghosn serves as chairman and CEO of both Renault and Nissan. The two cooperate closely and share resources extending far beyond their chief executive, but remain distinct companies rather than merge, as Fiat and Chrysler have. Renault Board approves alliance stability covenant between Renault and Nissan As early as 16th April 2015, the Renault Board of Directors unanimously reiterated that the sustainability, success and resilience of the Alliance since its very inception in 1999 were based on a balance of shares held by Renault and Nissan.
