Nissan’s Smart Rearview Mirror wins 2014 Traffic Safety Achievement Award

Nissan's Smart Rearview Mirror wins 2014 Traffic Safety Achievement Award

 

- World Traffic Safety Symposium says Nissan Smart Rearview Mirror will help make vehicles and roadways safer -         

 
NEW YORK - Nissan's Smart Rearview Mirror will be introduced in Japan later this year, but it's already being recognized for the anticipated positive effect it may have on roadways. Today at the New York International Auto Show, the World Traffic Safety Symposium named the Nissan Smart Rearview Mirror a 2014 Traffic Safety Achievement Award recipient, a recognition given annually to organizations and individuals that help create a safer environment for motorists and pedestrians.
Nissan recently unveiled the technology for North American audiences last week during media days at the 2014 New York International Auto Show.
Each year, the World Traffic Safety Symposium addresses important traffic safety issues in an effort to minimize injuries and fatalities on America's roadways, culminating in a presentation of the most interesting and innovative advancements in traffic safety. Nissan's Smart Rearview Mirror - the world's first LCD monitor that not only provides clear rearward visibility under various conditions, but also allows the driver the ability to switch between the LCD monitor and the traditional rearview mirror - was one of only three winners recognized for demonstrating "the most cutting-edge, life-saving safety features available in vehicles today," according to the World Traffic Safety Symposium.

"Safety is a top priority for Nissan, and our products continue to evolve to meet regulations and consumer expectations," said Pierre Loing, vice president, Product Planning, Nissan North America, Inc. "By improving rearward visibility, we hope Smart Rearview Mirror will help make roads safer with potential ancillary benefits for vehicle design."
With conventional rearview mirrors, rearward visibility can be obstructed by tall passengers in the rear seats, luggage stacked high in the vehicle's rear compartment or even the design of the vehicle. Smart Rearview Mirror can help provide rearward visibility free from these and other in-vehicle obstructions as well as traditional blind spots, thanks to a high resolution camera mounted at the rear of the vehicle.
In addition to the ability to provide a clearer rear view, the Smart Rearview Mirror can also display a crisp, clear image in a variety of other circumstances. The high-quality camera and image processing system implemented in the LCD monitor consistently produces an image with minimal glare, even during sunrise or sunset conditions or when being followed by a vehicle with strong headlights. Visibility during nighttime driving and at dawn and dusk are also improved from that of a standard rearview mirror.
The Smart Rearview Mirror's high-resolution camera displays its images on an LCD monitor built into the rearview mirror, which also functions as a conventional rearview mirror. The camera projects a clear image onto the monitor, giving the driver a better view of conditions behind the vehicle.
Nissan is planning to introduce the Smart Rearview Mirror to global markets in the near future after an initial rollout to Japanese consumers this spring.

Nissan develops world first analysis technique for better lithium ion battery durability

Nissan develops world first analysis technique for better lithium ion battery durability

 

YOKOHAMA, Japan - Can the battery performance of electric vehicles be improved by observing electrons? Nissan sought an answer to this question through an advanced research project in partnership with universities in Japan. The result: Nissan Motor Company and its affiliate Nissan Arc Ltd. today announced the development of the world's first analysis method that enables direct observation of electron activity in the cathode material of lithium ion batteries during charging and discharging.

Applying this analysis technique to future research and design of battery materials could enable Nissan researchers to develop high-capacity and high-durability batteries that may extend the driving distance of zero emission EVs and improve their durability.

Nissan Arc Ltd., a 100-percent subsidiary of Nissan Motor Company, developed the analysis method in a joint R&D effort with Tokyo University, Kyoto University and Osaka Prefecture University. The newly developed technique provides an accurate depiction of how electrons are emitted from certain elements that constitute the cathode material of lithium ion batteries when charging and discharging.

Takao Asami, Nissan senior vice president and president of Nissan Arc Ltd., said: "Creating this analysis technique was a major step toward the further development of high-capacity, next-generation lithium ion batteries. It will play an important part in our future R&D aimed at extending the driving range of future zero emission vehicles."

In order to develop high capacity, long-life lithium ion batteries, the maximum possible amount of lithium must be stored in the electrode's active material, which allows it to generate the highest possible number of electrons. To develop such a material, an accurate reading of the electron activity inside the battery is essential. Existing analysis methods did not allow researchers to observe the movement of electrons. It was not possible to determine how the various electrodes' active material - i.e. manganese (Mn), cobalt (Co), nickel (Ni), oxygen (O) - was emitting electrons and how many electrons were actually being emitted.

The newly developed analysis method combines x-ray absorption spectroscopy¹ that utilizes L-absorption edges² and the first principle calculation³ from Japan's Earth Simulator supercomputer?.

X-ray absorption spectroscopy had been used in the past to analyze batteries. However, the majority of this analysis was done using K-absorption edges that can only observe restrained electrons in the atom (electrons that are not involved in the charging and discharging due to the vicinity to the nucleus) and not the actual electrons involved in cell reaction. By applying x-ray absorption spectroscopy that utilizes L-absorption edges, electrons that were directly involved with the cell reaction can be observed. Accurate analysis of the amount of electron mobility is made possible by combining the observation results with first principle calculations from the Earth Simulator supercomputer.

For years scientists have wanted to understand the origin of electrons during charging and discharging, and this newly-developed analysis method finally makes it possible. Scientists can observe the exact phenomenon inside a battery cell, especially the behavior of active materials of electrodes, permitting further study of better-performing, longer-lasting electrode materials.

Nissan Arc has used the new analysis technique to investigate lithium-rich high-capacity electrode materials, which are considered promising agents to increase energy density by 150 percent. The analysis revealed that at a high potential state, electrons originating from oxygen were active during charging. Meanwhile, electrons that originated from manganese were observed to be active during the discharge reaction. These findings were a big step forward toward the commercial development of lithium-rich electrode materials, which can produce higher-capacity, long-lasting batteries.

*1 X-ray absorption spectroscopy: An analysis method of electronic state and local structure of materials obtained by measuring the increase x-ray absorption energy (absorption edge) after irradiating variant strength x-rays.

*2 Absorption edge: The x-ray absorption value of energy (wavelength) that abruptly increases when the x-ray energy (wavelength) is changed. It is referred to as the K-absorption edge or L-absorption edge depending on the electron orbit.

*3 First Principle Calculation: A calculation method of electronic states without the use of experimental values.

*4 Earth Simulator: A supercomputer owned by the Japan Marine Science and Technology Center (JAMSTEC) originally developed to evaluate global environments.
