Nissan, least profitable Japanese automaker in Q3, stays strong on EVs

Nissan had some not-so-good financial news to report today. Despite a 57-percent net income increase, Nissan was Japan's least-profitable carmaker for the third quarter of last year. A weak yen helped put the company's operating profit below the estimates of financial analysts. In a speech on the financial situation, Nissan corporate vice president Joji Tagawa said "These results, however, do not reflect the full potential of Nissan." Given our focus on expensive electric vehicles, among other things, we wondered how this might affect EVs. One of the financial analysts told Bloomberg that the news is a "crisis" at the company, but the official word is that things are steady as she goes on the EV front. In his speech, Tagawa reaffirmed the company's strong belief in plug-in vehicles, saying that "Nissan's EV strategy will accelerate with the launch in fiscal 2014 of the e-NV200, the second all-electric model available globally." That electric van has the potential "to transform emissions among commercial vehicles" and Nissan remains interested in initiatives such as EV carsharing in Japan and the continued deployment of charging infrastructure. The speech transcript is available below. In a statement to AutoblogGreen, Billy Hayes, Nissan's vice president and program director, said that, "Nissan considers zero emission vehicles to be the ultimate solution for realizing sustainable mobility in the future and is strongly committed to EV technologies. Nissan's investment in Leaf and EV technology is positive for the company's business results over the lifecycle, and accelerating sales of Leaf only help to build economies of scale and improve the business model for the technology further." FY13 3Q financial results Nissan Motor Co., Ltd. Joji Tagawa, Corporate Vice President Introduction For the nine-month period, Nissan has made solid progress to improve its business performance. The pro forma nine-month financial results, and particularly those of the third quarter, are up compared to the same period last year, despite intense competition and uncertain economic conditions. These results, however, do not reflect the full potential of Nissan. Looking ahead to the quarter ending March 31, 2014, we expect to continue to improve our business results and as such, we are maintaining our prior profit outlook for the fiscal year.

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.

NHTSA opens investigation into 130k Nissan Versas for breaking springs

The National Highway Traffic Safety Administration has opened a preliminary evaluation into a suspension problem that could affect an estimated 130,000 Nissan Versas from 2008-2010. According to the government agency's documentation (here as a PDF), there have been 93 complaints of the front coil springs fracturing while driving in these vehicles. Based on reports so far, it appears to NHTSA that this problem can happen at any speed and without warning. When the spring breaks, the pieces can also puncture a tire or brake line. A preliminary evaluation sets out to investigate "the scope, frequency and safety-related consequence" of the potential problem. According to a portion of a statement from the automaker to Autoblog, "Nissan is cooperating fully to answer the agency's questions regarding this issue in a timely manner." INVESTIGATION Subject : Front Coil Spring Fracture Date Investigation Opened: MAY 13, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15019 Component(s): SUSPENSION All Products Associated with this Investigation Vehicle Make Model Model Year(s) NISSAN VERSA 2008-2010 Details Manufacturer: Nissan North America, Inc. SUMMARY: The Office of Defects Investigation (ODI) has received 93 complaints (VOQs) alleging incidents of front suspension coil spring fracture in model year (MY) 2008 through 2010 Nissan Versa passenger cars. Preliminary analysis of the complaints indicates that the coil spring failures occur without warning and can happen at any speed. One complaint (VOQ #10663102) reported the passenger-side coil spring fractured while traveling at 65 mph and caused a sudden tire failure by cutting the inner sidewall 360 degrees. Another complaint ( VOQ #10680740) reported the passenger-side coil spring fractured while traveling 40 mph and result in tire puncture and brake line failure. ODI has also received EWR field report information relating to coil spring failures in the subject vehicles. A Preliminary Evaluation has been opened to assess the scope, frequency and safety-related consequence of the alleged defect.
