Recharge Wrap-up: Toyota FCV ready for production, Nissan tests Leaf-to-Home energy management

Toyota will begin selling its hydrogen fuel cell vehicle (FCV) in Japan in December. The US and Europe can expect to see the car become available next summer. The FCV, which will likely be called "Mirai" (meaning "future") in Japan, is ready for production ahead of its initial deadline at the end of the fiscal year in March. Toyota planned for annual production of 700 units, but might increase output to meet higher-than-expected demand, which is currently nearing 1,000 units. The cars will mostly be sold in the four cities where a hydrogen fueling infrastructure is already being put in place: Tokyo, Nagoya, Osaka and Fukuoka. Read more at Nikkei Asian Review. Nissan is testing the Leaf EV as part of an energy management system including "Leaf to Home" technology. The system allows the Leaf to help support the power grid during peak energy usage, or provide backup power to a home or building during outages, particularly in emergencies like natural disasters. Using the Leaf's battery to provide electricity during peak hours would lessen the demand on the grid and make the system work more efficiently. Furthermore, if consumers are compensated for the energy saved by using the Leaf for power during periods of high demand, it could encourage more people to adopt the EV.

CDP keeps track of how much companies are disclosing about their impact on global climate change. "The need for data on corporate climate change impacts and strategies to reduce them has never been greater," says CDP CEO Paul Simpson. "For this reason we congratulate those businesses that have achieved a position on CDP's Climate Disclosure Leadership Index." Other perfect scores were earned by Nissan, BMW, Daimler and General Motors. Read more in the press release from Honda below. Scientists at Stanford University have developed a lithium ion battery that can warn users before it overheats. A thin layer of copper between the anode and the layer separating the anode from the cathode acts as a sensor. When it detects lithium buildups from overcharging are approaching the separator, it sends an early alert long before it gets to a point where it would cause a short (which could lead to a fire). The new safety measure could be used in all sorts of battery applications, and not be limited to EVs. Learn more at Phys.org.

Recharge Wrap-up: Toyota Prius, V earn IIHS awards, Mitsubishi Outlander PHEV approved for V2H

The Toyota Prius and Prius V have earned IIHS 2015 Top Safety Pick+ ratings. The Prius V was singled out for its improved performance in the small overlap crash test. Lexus CT models built after September 2014 were also given the distinguished safety rating. In all, eight vehicles from Toyota and Lexus earned Top Safety Pick+ awards, while four more from Toyota and Scion were named Top Safety Picks. Read more in the press release below. The Mitsubishi Outlander PHEV can now provide power to the home in Japan. The vehicle-to-home capability requires the CHAdeMO quick charging socket and either Mitsubishi's own Smart V2H system, or the EVPower Station or Tsubaki eLINK system. The Outlander PHEV gained vehicle-to-home approval alongside all-electric vehicles because its electric motor doesn't run when used in for this purpose. The system allows owners to power their homes during outages and emergencies, and the Outlander PHEV can also directly power appliances with its 1500W AC100V power feeder.

It shows the standard AC connectors for the US and Europe, DC and combination connectors for fast charging and, of course, Tesla's own charging connector for the Model S. It also shows the standard plug types used around the world, which are color coded by country on a world map. See the Electric Vehicle Institute's poster here, or read more at Green Car Reports. Toyota Decks the Halls with IIHS 2015 'Top Safety Pick' Awards Eight Toyota and Lexus Models Earn Institute's Highest Top Safety Pick+ Four Toyota and Scion Vehicles Named Top Safety Picks December 23, 2014 TORRANCE, Calif., Dec. 23, 2014 - On the 12th day of Christmas, the Insurance Institute for Highway Safety (IIHS) gave to Toyota, 12 awards awarding. In fact, the automaker won more awards than any other automaker, including the most of the Institute's highest honor. In all, eight Toyota and Lexus vehicles earned a Top Safety Pick+ rating. IIHS in particular recognized the Prius V for its significantly improved performance all-around in the small overlap crash test – naming it a Top Safety Pick+. The Toyota Sienna was also the only minivan awarded the 2015 Top Safety Pick + designation. IIHS also recognized four additional Toyota and Scion vehicles as 2015 Top Safety Picks.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
