Nissan to add Rogue, Murano hybrid around 2015

Except for the limited-production, Toyota-assisted Altima Hybrid, Nissan has pretty much shied away from hybrid vehicles, but that is all about to change. As a part of a plan to launch a total of 15 electrified vehicles by 2016, Nissan is launching the Pathfinder Hybrid, which goes on sale this fall, and we've heard in the past that the Altima will get another hybrid variant, as well. Now, Green Car Reports is confirming that the Murano and the smaller Rogue (seen above in next-gen prototype phase) will both receive hybrid powertrains.
Though riding on different platforms, both hybrid crossovers could share the system being introduced in the Pathfinder, consisting of a 2.5-liter supercharged four-cylinder engine, a 22-horsepower electric motor and a lithium-ion battery pack. There is still no word on when the next-gen Murano will arrive, but the 2014 Nissan Rogue will be introduced on September 10.

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.

Nissan tests fully autonomous ProPilot tech on Tokyo roads

We've been hearing a lot about Nissan's ProPilot technology lately. ProPilot Assist is coming to the U.S. in the Rogue, as well as the Leaf EV. For this generation, the system allows for Level 2 autonomous driving, which is essentially adaptive cruise control paired with a lane-keeping function. Later, Nissan will add ProPilot Park, which allows the car to park itself. The next generation of ProPilot, though, allows for Level 4 fully autonomous driving, even on urban streets, beginning in 2020. Nissan has announced that it has already tested it on public roads during a demonstration in Tokyo. The prototype test vehicle is an Infiniti Q50. It's fitted with 12 cameras, 12 sonar sensors, nine millimeter-wave radar sensors, six laser scanners and high-definition mapping, all run through artificial intelligence. With this combination of hardware and software, the Q50 prototype can navigate across town or on the highway, automating the entire driving duties from the moment the passenger selects a destination until their arrival. It can tackle busy intersections and respond to obstacles in the road, providing what Nissan claims is a "human-like driving feel that gives passengers peace of mind." View 29 Photos "Our next-generation ProPilot prototype showcases technology that will be available for real-world use from 2020," said Takao Asami, Nissan's senior VP of research and advanced engineering. "Today's demonstration is another example of our successful work toward creating an autonomous driving future for all." Autoblog has already had the chance to sample the current generation of ProPilot Assist, in both the Leaf and the Rogue. While there has been a little bit of disagreement in our office, most of us have found the technology to work fairly well, and are looking forward to trying the next generation of semi-autonomous and autonomous systems. As the tech advances, it will only get smoother and smarter.
